1. A Qualitative Examination of a Reminiscence Intervention for Older Adults Using Three-Dimensional (3D) Printed Objects.

Author

Anderson, Keith A., Berg-Weger, Marla, Olofinboba, Olu, and Plocher, Tom

Abstract

Reminiscence has been found to be an effective therapy for older adults and researchers and practitioners have identified a range of benefits, from cognitive stimulation to the reconciliation of past experiences. In this qualitative study, the authors explore the experiences of older adults engaged in a technology-enhanced form of reminiscence therapy (RT) using three-dimensional (3D) printed objects from peoples' past. Content analysis of individual interviews with seven participants (n = 7) revealed three themes: (1) positive experiences with the RT intervention; (2) reflections on the use of 3D printed objects; and (3) the development of relationships between participants and researchers. These findings suggest that RT using 3D printed objects can be effective, but only if objects are accurate and if it suits participants' personalities. Researchers and practitioners may find that the use of 3D printed objects can enhance their RT interventions and thereby enrich the lives of older adults. [ABSTRACT FROM AUTHOR]

Abstract

Objective: The objective of the current project was to determine the feasibility of using 3D printed technology to facilitate reminiscence-related activities for persons with memory loss (PWMLs).Methods: A parallel convergent mixed methods design was used. Fifteen PWMLs, 13 family members, and six staff from two residential long-term care facilities participated. Participants were observed and interviewed initially, during a 2-week reminiscence session, and again during a 1-month reminiscence session. Staff participants also completed a 1-month focus group, and staff and family members were administered a 3D printing review checklist at 1-month.Results: The integrated qualitative and quantitative data strongly suggested that PWMLs enjoyed using the 3D objects, were engaged while doing so and appeared to value the objects due to their personalized nature. The use of 3D printed objects also appeared to encourage family involvement as well as family and staff interactions with PWMLs. Barriers to use included memory impairment and behavioral issues.Conclusions: The use of 3D printed objects could provide an easy-to-use, well-received, person-centered approach that augments current reminiscence strategies for PWMLs.

Abstract

For the convenience of firefighters' decision-making and operation, touch screen display was chosen as the preferred interface for a fire information display system. Few studies were conducted to determine comfortable button/icon size on touch screens. This experiment investigated the effect of four factors on operators' performance with touch screen: 1) button size (20*20, 30*30, 40*40, and 50*50 pixels 2), spacing between buttons (0, 5, 10, and 20 pixels), 3) button/icon types (digit buttons only, picture icons only, combination), and 4) glove wearing (wearing vs. not wearing). 14 males were asked to accomplish a series of matching tasks on touch screen with the forefinger of right hand. Results showed that the spacing between buttons/icons, and wearing or not wearing a glove did not affect performance. Subjects pointed to the digit buttons faster than the other two kinds of buttons/icons. There was a significant difference among button/icon sizes. People performed best when it was equal to or bigger than 40*40 pixels. [ABSTRACT FROM AUTHOR]

Abstract

Cultural models in terms of the characteristics and content of folk theories and folk psychology have been important to social scientists for centuries. We suggest that they should be at the heart of the scientific study of human-computer interaction (HCI). The CULTUSAB project is conducting an in-depth investigation of the key dimensions of culture that affect usability testing situations, including language, power distance, and cognitive style. All phases of the usability test are being evaluated for cultural impact, including planning, conducting, and reporting results. Special attention is being focused on subject-evaluator communication and cultural bias in the test design and structure of the user interface being tested. Experiments are being replicated in three countries: Denmark, India and China. The research will result in new testing methods and guidelines that increase the validity of usability tests by avoiding cultural bias, and allow us to produce comparable results across different countries.

25. Touch Screen User Interfaces for Older Adults: Button Size and Spacing.

Author

Abstract

This study investigated the optimal button size and spacing for touch screen user interfaces intended for use by older adults. Current recommendations in the literature are aimed at general audiences and fail to consider the specific needs of older adults. Three independent variables, button size, button spacing, and manual dexterity were studied in two experiments that measured reaction time, accuracy and user preferences. Design recommendations for touch screen button size and spacing for older adults are stated based on these experiments. The paper also discusses the role of manual dexterity in designing appropriate touch screen interfaces for older adults. [ABSTRACT FROM AUTHOR]

26. A Study on the Vertical Navigation of High Rise Buildings.

Carbonell, Jaime G., Siekmann, Jörg, Harris, Don, Xianghong Sun, Plocher, Tom, and Weina Qu

Abstract

Scroll bar and stab touch screen controls were designed and compared to a soft keyboard to help firefighters perform vertical navigation tasks for high-rise buildings depicted on a graphical display. 18 male subjects were asked to accomplish three experimental tasks: 1) input floor number and navigate to the floor, 2) switch the current floor to another one that was two floors higher/lower, and 3) check around the floors in the high rise to find the one on fire. Task completion time and number of screen operations were recorded. Results showed that, keyboard method of floor selection was the fastest, and scroll bar the slowest. In Task 1 and Task 2, the least number of screen operations were shown with soft keyboard. But in Task 3, keyboard was slowest. The other two control methods were not sensitive to tasks. Design implications for scroll bar and stab controls are discussed. [ABSTRACT FROM AUTHOR]

28. Crewcut: A New Tool for Predicting Human Performance in Conceptual Systems

Author

Plocher, Tom, Lockett, John F., Kovach, Peter, and Powers, Jeffrey

Abstract

CREWCUT was developed in response to the need for a tool that can predict the effects of automation on operator workload and system performance. Previous analytical tools have considered either operator workload alone or system performance alone, neglecting the important interaction. In contrast, CREWCUT integrates workload estimation algorithms into a dynamic human performance simulation framework, such that the performance consequences of excessive workload can be observed and quantified. CREWCUT also provides a mechanism for simulating operator coping or workload management strategies and their effects on system performance.Workload algorithms in CREWCUT are based on a multiple resource theoretical model that includes three workload components: 1) single task demands, 2) cognitive interference, and 3) structural interference. Workload is computed as the demand placed on each mental resource at any given moment in the simulation, given the degree of conflict or interference in resource demands at that moment. When demands exceed threshold, workload management strategies are called into play by CREWCUT and attempt to reduce workload. Various performance penalties are assessed, depending upon the particular strategy selected and its degree of success in normalizing workload.The effects of automation on technology insertion can be simulated in CREWCUT in terms of its effects on operator tasks (sequencing, allocation, time, and error parameters), workload demands, and crewstation displays and controls. The workload and system performance effects of display and control media, as well as the physical layout of the crewstation are considered. Both graphic and tabular simulation outputs are provided, supporting a variety of system performance measures.
