Generally we use simple led regular static type display screen to deliver the message. Previously, to update the data either it may be large one it takes a long process to update data. Now a days scrolling type displays are more preferred over the static type displays. By adopting a programming device called NODEMCU, data can be displayed on dot matrix in scrolling manner. By adopting led 8x8 dot matrix using can controlled via IoT based system which controlled by mobile or laptop. Scrolling type text display boards, projects uses led dot matrix displays or regular outside purpose digital sign boards. The message scrolling displays are also type of scrolling LED display examples, presented here are nodemcu based led matrix display project. The led matrix is controlled using nodemcu by serial communication protocols. In this pair of 8*8 led Matrix display modules have used to display the transmitted message on Matrix display. nodemcu is heart of this project. The nodemcu is the transmitter to send data, and the receiver is led matrix display to display message on it.

Augmented reality (AR) optical-see-through (OST) head-mounted displays (HMD) have developed to a point where browsing information on the go is possible. In this paper, we investigate the readability of text on an AR HMD while the user is walking. There are two common methods of displaying text on a HMD: anchoring the text on the screen coordinate system or the world coordinate system. We report on the results of two laboratory experiments comparing text readability when the text is displayed in these two coordinate systems, and while the participants walked on a treadmill. In the first experiment, the participants read letter strings comprising Sloane letters, whereas the second experiment used English words. In addition to evaluating the text readability and workload experienced by participants, we employed IMU sensors to compare the effects of the text display method on the participants’ head movement and gait. In both experiments, the reading speed and head movement were significantly higher and mental workload significantly lower for the world coordinate system than for the screen coordinate system. These results suggest that text readability while walking is better on the world coordinate system, and displaying text with the screen coordinate system results in an unnatural gait owing to the user trying to keep their head still in an effort to stabilize the HMD screen.

A hand gesture is a non-verbal means of communication involving motion of fingers to convey information. Hand gesture are used in sign language and are a way of communication for deaf and mute people. Common public most often is unable to understand the sign language. So, in this paper we aim to provide an electronic method for hand gesture recognition which is cost effective, this system makes use of flex sensors, on-board gyroscope and accelerometer. A flex sensor works on the principle of change in the internal resistance to detect the angle made by the user's finger at any given time. The flexes made by hand in different combinations amount to a gesture and this gesture can be converted into speech signals or as a text display to aid physically challenged people. A smart glove is designed which has an Arduino circuit which is equipped with the custom-made flex sensors, an on-board gyroscope and an accelerometer, out of which the last two components are used to supplement the gestures detected by a flex sensor.

This work describes a colorimetric signaling approach for competitive lateral flow immunoassays (LFIAs) enabling sensitive and semiquantitative direct visual result readout in the form of "text", demonstrated on the example of 8-hydroxy-2'-deoxyguanosine (8-OHdG) detection. The distinctive feature of the developed text-displaying LFIA (TD-LFIA) is the test zone system consisting of a combination of two types of inkjet-deposited capture molecules referred to as "mask antigen" and "text antibody", allowing for sensitive turn-on signaling as opposed to the inverse response of conventional competitive LFIAs. The user operation is limited to sample application, followed by direct reading of assay results written in text after approximately 10 min. TD-LFIAs enabled the visual detection of 8-OHdG at concentrations down to 3 ng/mL, which is a 2-3 orders of magnitude lower visual detection limit than that achieved with the corresponding conventional design and is comparable to the existing LFIAs relying on external signal readout equipment. Highly reproducible observer-independent assay performance was confirmed, and the result interpretation is not influenced by sample color and readout timing. Making use of customizable threshold settings for text appearance, a device for semiquantitative assays was developed and successfully applied to the detection of 8-OHdG at four concentration levels (trace, low, medium, and high) in 54 human urine samples within the clinically relevant concentration range. The sensitive and intuitive signaling method of the developed system offers great potential for an alternative competitive LFIA platform suitable for real-world point-of-care testing applications.

When typing on smartphones or palm tablets, users generally make an effort to type correctly while simultaneously checking the small keyboard and the text display. Unlike physical keyboards that allow users to perform typing based on long-term muscle memory, virtual keyboards typically require more frequent eye movements between the keyboard and the text display areas. This study proposes a new way of designing a virtual keyboard display to reduce the effort associated with frequent eye-movements. For this study, we developed virtual keyboard display systems featuring both static and dynamic word-by-word (WBW) feedback displays. The two display systems were examined in comparison with a more conventional method known as character-by-character (CBC) feedback display. We investigated user satisfaction, typing performance and the user’s eye gaze shifts. Eye gaze shifts were measured between the keyboard and the text display areas across the three conditions using self-report, log, and eye-tracking measures. In the static WBW condition, the words being typed displayed in a fixed area at the top of the virtual keyboard; in the dynamic WBW display, the words displayed in a small popup window at the tip of the selected key. Using a repeated measure experiment for the three display conditions, participants were asked to type fifteen phrases using a palm tablet while wearing eye-tracking glasses for each condition. We conducted a mixed-model design ANOVA with group (SLOW vs. FAST typing; men vs. women) as between-subject factors and display condition (CBC vs. WBW). We found a significant (11%) improvement in typing speed with the dynamic WBW over the CBC display for less experienced keyboard users. In addition, participants reported higher satisfaction with the two WBW conditions than the CBC condition. Eye fixations, dwell times, and heat map data also supported that WBW displays are advantageous for less experienced, slower typists by helping them stay focused more on the keyboard, thus reducing eye transitions to the text display. Our study systematically demonstrates how and to what extent the virtual keyboard display strategy influences typing performance and subjective experience based on self-reports and eye-tracking measures. The approach and findings of this study should provide useful information and practical guidance to mobile application developers and designers who are interested in improving virtual keyboard functionalities and user satisfaction.

We designed and evaluated SplitVectors, a new vector field display approach to help scientists perform new discrimination tasks on large-magnitude-range scientific data shown in three-dimensional (3D) visualization environments. SplitVectors uses scientific notation to display vector magnitude, thus improving legibility. We present an empirical study comparing the SplitVectors approach with three other approaches - direct linear representation, logarithmic, and text display commonly used in scientific visualizations. Twenty participants performed three domain analysis tasks: reading numerical values (a discrimination task), finding the ratio between values (a discrimination task), and finding the larger of two vectors (a pattern detection task). Participants used both mono and stereo conditions. Our results suggest the following: (1) SplitVectors improve accuracy by about 10 times compared to linear mapping and by four times to logarithmic in discrimination tasks; (2) SplitVectors have no significant differences from the textual display approach, but reduce cluttering in the scene; (3) SplitVectors and textual display are less sensitive to data scale than linear and logarithmic approaches; (4) using logarithmic can be problematic as participants' confidence was as high as directly reading from the textual display, but their accuracy was poor; and (5) Stereoscopy improved performance, especially in more challenging discrimination tasks.

Running text or commonly known as text running a medium to deliver information that is most often encountered as a means of advertising that are informative. Running text display is generally in the form of LED-LED are connected and assembled into a row of LED or may be a dot matrix. Submission of information by displaying the running text has not been effective and efficient in terms of use. There are still shortcomings that enable people to experience vision errors and too long waiting for the text to be displayed. Thus the necessary tools to deliver information that can work optimally to minimize shortages by designing a control tool running text using voice (voice) and arduino uno. This tool uses a series of android smartphones facilities to provide input sound is converted into a data string and compiled in arduino using serial communications, and will be displayed on the LED Dotmatrix as output. Submission of information by using running text that comes with using sound can improve efficiency and effectiveness in the use and also the time required so that it can reduce the level of difficulty of the user in receiving the information

In this paper we discuss the development and implementation of a loosely coupled expert database system supporting catalog sales for a large industrial supplier, Richmond Supply Company. The system is called an Automated Catalog System (ACS) because it automates most of the sales, purchasing, and technical support processes. The ACS enables the user to search a database of products using any combination of the seller-defined parameters and select items for full-page graphic and text display. It helps the user build purchase orders and send them via the push of a button through his or her modem. Since the average customer is not very familiar with the technical aspects of the products they are going to purchase, expert product selectors have been incorporated. The product selectors, which are small expert systems on different product categories such as casters, paint, and gloves, aim to help users make better, more informed purchase decisions.

The number of users of hearing aids is expected to increase along with the aging society. On the other hand, the hearing aid is not perfect device for listening, user have to guess what he cannot hear clearly. However, this guess requires a great deal of user effort.In this study, a speech-text display system as an auxiliary device of the hearing aid is proposed. This system displays the speech text of the speaker in front of the user on the HoloLens by voice recognition. This makes it possible to visually assist the conversation which cannot be heard even by using a hearing aid. Furthermore, by having the sound source segregation function, it is possible to segregate the speeches of the plural speakers in real time, and to display the speech-text of each speaker on the HoloLens. In this paper, the outline of our system is described, the evaluation results of each function are shown, and the effectiveness of the speech-text display system is confirmed.

This article describes the design and implementation of LiftingDoneRight, a novel system for healthcare professionals to enhance their compliance with best practices and regulations regarding proper body mechanics for lifting and pulling activities. The system uses Microsoft Kinect to track the motion of consented users non-intrusively. The system relies on the use of a smartwatch to deliver an alert via vibration and text display whenever a wrong activity that violated the proper body mechanics has been detected. A core contribution of this study is a registration mechanism for a healthcare professional to explicitly give permission to the system to monitor his or her activities. Furthermore, a non-intrusive biometrics-based single sign-on mechanism is incorporated into the system to allow a user to be automatically identified for tracking as long as the user has manually registered with the system before. Finally, the system offers a number of configurations to accommodate different usability needs and privacy requirements.

A smart pill box (SPB) for the elderly and nursing homes meets the needs of the market by integrating electronic technology and network functionality. The interactive SPB, which features a particular device that contains embedded sensors in each compartment that not only transmits detected signals to website when users are taking their pills but also receives a remind message back to the LCD screen on SPB by displaying words and/or patterns, or speaking a voice. This study uses the Webduino module installed in SPB to achieve two-way messaging with remote relatives via internet of thing (IoT). The module first reads the sensing signal in the kit and uses WiFi to transmit the signal to WiFi Router, and then sends the medication information to a remote webpage or cell phone for monitoring (on LCD). Remote relatives can input care messages on the webpage or mobile phone to send a signal back to the WiFi Router and then to Webduino module. After receiving the signal, Webduino will send it to Arduino for text display and voice playback in the SPB. Therefore, the elderly staying in their home or nursing home institution can easily manage their medication via this application. The smart interactive pill box will be crucial for medical care management for elder persons of this aging population or in the future.

Despite the popularity of mobile reading devices, many studies have indicated that small screens restrict information transmission, adversely affecting reading performance on mobile devices. Moreover, mobile reading typically occurs in different reading contexts. Therefore, suitable text display type for mobile reading in different reading contexts should be considered, such that learners can effectively read content. This work selected the frequently used static and dynamic text display types (i.e. Paging and Auto-scrolling) and assessed their effects on mobile reading performance. Furthermore, the features of static and dynamic text display types were considered when designing a mixed text display type for mobile reading. Based on brainwave detector, reading-comprehension test sheet, and cognitive-load scale, this work designed a mobile reading experiment with a two-factor experimental design to assess the effects of the selected static, dynamic, and designed text display types, which were respectively ...

This study investigated the effects of display method, number of message lines and text colour on comprehension performance and subjective preferences for reading Chinese on a light-emitting diode display. The factors and levels studied were: two text display methods (rapid serial visual presentation ‘rapid serial visual presentation (RSVP)’ and paged view scrolling), four numbers of message lines displayed at a time (one to four lines) and three text colours (amber, green and red). The RSVP method resulted in higher comprehension scores than the paged view scrolling method, and the green text produced better comprehension score than amber or red. However, the paged view scrolling received better subjective evaluation ratings than the RSVP method. A multiline display was found to be superior to a single-line display for both comprehension scores and subjective evaluations. The results here provide useful ergonomics recommendations for choice of appropriate display method and format setting for presenting Chinese messages on light-emitting diode displays.

The effectiveness of tablet computers to supplement or replace paper-based text in everyday life has yet to be fully revealed. Previous investigations comparing reading performance using tablets and paper have, however, reported inconsistent results. Furthermore, the interpretability of some previous findings is limited by lack of experimental control over variables like text display conditions. In the current study, we investigated reading performance for text presented on tablet and paper. Crucially, the levels of luminance and contrast were matched precisely across tablet and paper. The study used Arabic text which differs substantially from the languages used previously to investigate effects of tablet and paper on reading, thus offering a distinctive test of the influence of these two media on reading performance. The results suggest that when text display conditions are well-matched, there is no reliable difference in reading performance between the two media. Also, neither the order of medium (reading from tablet or paper first), nor familiarity with using a tablet significantly influence reading performance. These results call into question previous suggestions that reading from tablets is linked to poorer reading performance, and demonstrate the benefits of controlling text display conditions. These findings are of interest to reading scientists and educators.

A focus group session is a useful tool for learning user expectations, preferences, and suggested enhancements during the design stage of a new product. This paper showcases the usefulness of using a mixed-method focus group study of first responders to examine the design of a hand-held radiation detector. The study used a survey and a semi-structured script that explored five main topics: difficulties of using radiation detection with respect to the equipment and environment; preferences for handle design; preferences for control design; preferences for screen, menu, and interface design, and instructional and maintenance issues. The focus group indicated a desire for fewer and bigger buttons to control the device, a desire for a san serif font type for the display, a request to minimize the use of abbreviations and symbols in the text display, having a color coding display bar to describe radiation levels, and a need for detailed maintenance procedures and processes. These results provide important feedback for planning the development and testing of a more ergonomic radiation detector. Relevance to industry A hand-held radiation detector to test for fissionable materials is one of the essential tools used by first responders. This paper presents the results from a focus group of first responders exploring characteristics for a more ergonomic detector.

The purpose of this study was to evaluate age differences in the visual demands imposed by reading in-vehicle text message displays during simulated driving. Visual demand was operationalized in terms of five eye gaze data parameters. Sixteen young (mean age=20) and 16 older (mean age=77) licensed drivers served as participants. They were required to read variable length text messages from a console mounted display while driving on straight segments on a simulated rural highway. Older drivers required much more time to complete the concurrent text reading task — especially for messages of longer lengths. As hypothesized, most of this age-difference resulted from an increase in the time spent reacquiring the road scene between successive glances to the text display. Lane keeping variability increased and driving speed decreased while reading text for older, but not younger, drivers. This pattern of findings is consistent with prior claims that driving performance in older adults is negatively influenced by problems with attention switching mechanisms.

Conversational agents that display many human qualities have become a valuable method business uses to communicate with online users to supply services or products, to help in online order process or to search the Web. The gaming industry and education may benefit from this type of interface. In this type of chats, users could have different alternatives: text display, photo of a real person, or a cartoon drawing and others. This is an exploratory study that reviews five randomly chosen conversations that an animated chatbot has with Web users. The character simulates human gestures, but they are stylized to reproduce animation standards. The goal of this exploratory study is to provide feedback that will help designers to improve the functionality of the conversational agent, identify user’s needs, define future research, and learn from previous errors. The methodology used was qualitative content analysis

Over the past 20 years web browsers have changed considerably from being a simple text display to now supporting complex multimedia applications. The client can now enjoy chatting, playing games and Internet banking. All these applications have something in common, they can be run on multiple platforms and in some cases they will run offline. With the introduction of HTML5 this evolution will continue, with browsers offering greater levels of functionality. This paper outlines the background study and the importance of new technologies, such as HTML5's new browser based storage called IndexedDB. We will show how the technology of storing data on the client side has changed over the time and how the technologies for storing data on the client will be used in future when considering known security issues. Further, we propose a solution to IndexedDB's known security issues in form of a security model, which will extend the current model.

Human eye gaze has recently been used as an effective input interface for wearable displays. In this paper, we propose a gaze-based interaction framework for optical see-through displays. The proposed system can automatically judge whether a user is engaged with virtual content in the display or focused on the real environment and can determine his or her cognitive state. With these analytic capacities, we implement several proactive system functions including adaptive brightness, scrolling, messaging, notification, and highlighting, which would otherwise require manual interaction. The goal is to manage the relationship between virtual and real, creating a more cohesive and seamless experience for the user. We conduct user experiments including attention engagement and cognitive state analysis, such as reading detection and gaze position estimation in a wearable display towards the design of augmented reality text display applications. The results from the experiments show robustness of the attention engagement and cognitive state analysis methods. A majority of the experiment participants (8/12) stated the proactive system functions are beneficial.

This study compared 30 undergraduate social work and speech language pathology students' recall of material presented through multimedia versus traditional lecture. Advanced multimedia included audio, video, animation, graphics, text, and special effects. Traditional lecture included a text display in the form of PowerPoint bullets only. Both conditions presented material on the brain and the ear. Quantitative and qualitative results indicated that multimedia presentations had a positive effect on learning. Similar findings were obtained during a follow-up study three weeks later.

As increasing amounts of information are viewed, read and manipulated digitally, many users still report performance and satisfaction costs with digital documents compared to paper equivalents. While many factors impact this process, image quality has been assumed by many to have relatively little impact once current screen display standards are maintained. We test this hypothesis by comparing users on a variety of routine information tasks performed on standard and enhanced screen displays. Using Microsoft ClearType, a font technology which enhances text display resolution by accessing vertical color stripes at the pixel level, we examined user performance on reading, editing and searching tasks with routine office applications. Results suggest that for tasks involving lengthy eye-on-text interaction (e.g., reading for comprehension) advances in image quality can still yield significant improvements in performance for most users.

The presentation of packet-level communication network performance data to a user in an easy to assimilate, visual form by computer screen is considered. Standard presentation mechanisms such as bar graphs and numeric (text) displays require considerable concentration on behalf of the operator if more than a very small number of measurement values are presented. However, for many network operation tasks the initial requirement is for the relative value of the measurements and any trends in these measurements to be readily identifiable. A different approach to measurement presentation has therefore been considered whereby an object's shape is distorted in proportion to the values of a set of measurement data. A casual viewing of the object therefore immediately indicates the relative values of the measurements. This approach has been applied to the presentation of packet delay values for a commercially operational network, and its use in a performance measurement system for the commercial communication network is described.

A message presentation and processing model is presented here. It was used, in two experiments, to study how different types of highlighting and text display color combinations affect reading performance. We found that highlighting can significantly improve table searching and that the best highlighting method was color, followed by reverse video and blinking. When different color combinations were used for textual display, the reading speed was higher but the visual preference was lower for situations in which the foreground luminance was lower than the background luminance or the foreground chroma was lower than the background chroma. Hue combinations also affected both visual preference and reading speed, but did not override the dominant impacts of luminance and chroma contrast. The color impact on visual preference was not consistent with its impact on reading speed. Based on these findings, design guidelines are proposed.

As an abstract concept, ‘location error’ in is considered to be an important element with great difficult to understand and apply. The paper designs and develops an instrument to measure the location error. The location error is affected by different position methods and reference selection. So we choose position element by rotating the disk. The tiny movement transfers by grating ruler and programming by PLC can show the error on text display, which also helps students understand the position principle and related concepts of location error. After comparing measurement results with theoretical calculations and analyzing the measurement accuracy, the paper draws a conclusion that the teaching aid owns reliability and a promotion of high value.

The purpose of this study was to investigate the alignments in the use of theory, principles and guidelines in instructional design books and popular books on design. The review of literature was conducted in three parts. The first part of the literature review was a general review of literature and it was conducted on cognitive information processing, cognitive load theory, affordance theory and text display. The second part of the literature review extracted the theories, principles and guidelines from four books on instructional design and technology. Six theories were extracted. The six theories extracted from these four books of instructional design and technology were cognitive information processing theory, cognitive load theory, multimedia theory, perception theory, minimalism theory and motivation theories. The third part of the review of literature was on content analysis, the different definitions of content analysis and the historical background of content analysis. Two sets of books were used in the study. The first set of books was instructional design and technology textbooks. These books were referred to as the scholarly books. The second set of books was selected by systematic sampling. These second set of books were the ten most positively reviewed books on web design from Amazon.com Inc. These ten books were pruned down to four books by a panel of experts. This second set of books was referred to as the popular books. A content analysis was conducted on the scholarly and the popular books. The theories, principles and guidelines extracted from the four scholarly books were aligned with the codified themes, word phrases and word sense from the four popular books. The results were tabulated under categories identified. The results showed that two of the popular books did not address theory in their content. The two other popular books addressed guidelines and principles applicable to the theories extracted in the scholarly books. The scholarly books gave theoretical foundations for their guidelines while the popular books did not give a theoretical foundation for their guidelines. Ph. D.

Thirty-six participants were tested in a flight simulator on their ability to decide which of two airports was furthest from a storm front, based on the manner in which information was presented on a navigational display. Results indicated that use of a moving-map display was superior to either a tabular, text-only display or a text display with an additional orienting symbol. In addition, in contrast to an earlier study (Williams, 1999), pilots performed better using a north-up map than when using a track-up map. Discussion of the results focuses on recommendations for moving-map displays and the display requirements for support of the nearest-airport function within a navigational display in particular.

Thirty-six participants were tested on their ability to orient toward the nearest airport based on the manner in which information was presented on a global positioning system (GPS) area navigation display. Results indicated that use of the tabular, text-only format normally found on such displays was significantly slower and less accurate than either a map display of nearest airport information or a text display that included an orientation symbol. Additionally, pilots ignored information from the heading indicator, focusing on the GPS to perform the task. Discussion focuses on the need to support pilot decision making.

In this project we use the technologies of virtual reality, conversional interfaces, animated touch screens, metro-style navigation to allow users to immerse inside Qur'an and some of its related sciences. The goal is to build a small scale implementation of only Part 30 "IOA Ua" of a Conversional, Animated Qur'an Memorizer application. The implementation is ported on major smart phones and here w describe the system model and design decisions. Major features of the application are demonstrated and explained. The animated conversional interface is described with its options to change view and customize its drop down menus locations and contents. The flexible indexing of both Qur'an, its narrators, types of recitation, links to Tafseers and glossaries along with the metro-style touch screen navigation and book marking are demonstrated. The search capability of both text and audio has been demonstrated. Tracking of what one has memorized from each Surah so far with ability to change text display through the Qur'an viewer (e.g. display movement characters (CaEOsia)) are demonstrated. The bi-lingual display of Qur'an Tafseers and glossaries are also demonstrated. Changing setting and getting help are also demonstrated. Audi recording is implemented but audio voice recognition, correction and teach exams have not been implemented completely yet in the current small scale implementation. In fact the usability of the conversional, animated, immersive interface screens allows easy interaction with the application. Also on-line help is extensive and allow easy navigation among various interface screens.

Web browsers and e-book are some of the most dominant applications on mobile devices today. They spend a significant amount of time handling text in these documents. Based on the experimental results from different commercial web browsers, the majority of the time spent to display text is dedicated to layout design and painting the bitmaps of the character glyphs on the screen; the time needed to rasterize the bitmaps of these glyphs is negligible. Many efforts have been made in software to improve the performance of text layout and display and very few are trying to come up with parallel processing schemes for System-On-Chip (SoC) designs to better handle this graphic processing. This work introduces a new novel hardware-software hybrid algorithm which performs the layout design of text and displays it faster by using a small piece of hardware which can easily be added to the SoCs of today's mobile devices. This work also introduces a novel method for applying kerning to layout design process. The performance of the algorithms are compared to WebKit, the most widely used web rendering framework, and has resulted in a 29X and 192X performance increases in layout design when kerning is both used and not used respectively.

Design variables surrounding the presentation of signal words in warnings have been previously shown to affect performance, or variables likely to be related to performance. The present study emphasized the signal word WARNING by presenting it in red, surrounded by a red border. It was at the head of an otherwise black pesticide label that used 8-point type. A study using 24 undergraduates investigated the effect of signal-word font size (8 to 32 points), white space around the signal word (2 to 32 points), and border width (1 to 8 points) on the rated urgency of the label. A measure of the aesthetic merit of each label was also obtained from nine design students and professionals. Seven levels of each variable were used, covering the practically-useful range of each variable in the circumstances. Results showed a linear relationship between each variable and perceived urgency, with text size having the greatest effect, followed by border width. It was shown that, within the variable ranges used, the perc...
