5. HCCI Tool: A Lens to Support Industrial Designers during the Conceptualisation of Smart Products

Author

De Ruyck, Olivia, Conradie, Peter, Van Hove, Stephanie, All, Anissa, Baccarne, Bastiaan, De Marez, Lieven, and Saldien, Jelle

Abstract

Interactions between humans and smart products (i.e. digital components integrated in physical Internet of Things devices) are becoming more complex and less visible. Yet designers lack tools to capture these interactions and incorporate them into their design. In this paper we present the Human-Computer-Context Interaction (HCCI) tool that helps the designer to consider the different interactions of the user early in the conceptualisation phase, in order to eventually improve the user experience for smart products. This tool introduces 5 relevant interaction levels to be considered, when defining the context-of-use. In this paper we assess the use of the tool by means of a design challenge with a total of 34 industrial design students, given the task to design a smart kitchen concept. The tool was evaluated by a mixed method approach. Results show that the tool was evaluated as useful and usable during the early concept phase of the design of smart products. Unsupported concepts typically envisioned a single user interacting with one object through explicit interactions. Hence, tool-supported designs were more holistic and better captured interactions with other objects, users, content and services. From this we conclude that the tool can help to detect possible pitfalls of design selections. The tool is aimed to be used in a new product development process by HCI researchers, designers, and developers and is technology independent. Based on observations and participant feedback, we reflect on the strengths and limitations of this tool.

13. Exploratory Study on User's Dynamic Visual Acuity and Quality Perception of Impaired Images

Subjects

Abstract

In this paper we assess the impact of head movement on user's visual acuity and their quality perception of impaired images. There are physical limitations on the amount of visual information a person can perceive and physical limitations regarding the speed at which our body, and as a consequence our head, can explore a scene. In these limitations lie fundamental solutions for the communication of multimedia systems. As such, subjects were asked to evaluate the perceptual quality of static images presented on a TV screen while their head was in a dynamic (moving) state. The idea is potentially applicable to virtual reality applications and therefore, we also measured the image quality perception of each subject on a head mounted display. Experiments show the significant decrease in visual acuity and quality perception when the user's head is not static, and give an indication on how much the quality can be reduced without the user noticing any impairments., Comment: 6 pages, 5 figures

22. Networked gift-giving: Ethno-religious minority youths' negotiation of status and social ties in a society of distrust.

Abstract

The reciprocal exchanges of messages, likes, and pictures on social media are typical expressions of mobile youth culture. After all, it is well-established that young people's disclosure practices support their efforts to maintain relationships, gain autonomy, and, by large, consolidate a place in the world. What is often missing, however, is an exploration of how the specific socio-cultural contexts of ethno-religious minority youths shape and are shaped by social media appropriations. Therefore, we conducted a 15-month ethnographic study among ethno-religious minority youths in which we investigated networked gift-giving practices. We stress the notion of "networked" because the results illustrate how these young people appropriate the amplified visibility of their relational maintenance behaviors on social media in order to negotiate status and social ties. We connect these findings to the concept of a "distrustful society" as the participants hold a general distrust in society due to experiences of racism and marginalization. [ABSTRACT FROM AUTHOR]

34. Mobile Learning in Secondary Education: Perceptions and Acceptance of Tablets of Teachers and Pupils

Author

Montrieux, Hannelore, Courtois, Cédric, De Grove, Frederik, Raes, Annelies, Schellens, Tammy, and De Marez, Lieven

Abstract

This paper reports on the introduction of the tablet computer as a personal, mobile learning tool in a secondary school in Flanders, Belgium. In this longitudinal research project, drawing upon the Theory of Planned Behavior, we question the relative extent to which attitude, subjective norm, and self-efficacy explain the prospective uptake of the device for educational purposes. The results indicate that attitudes towards the rollout are generally positive. Teachers are dominantly intrinsically motivated, welcoming it as a useful and easy to use aid. The role of attitude among pupils is strong, however they do report feelings of social influence, albeit mostly by parents and peers. The pupils also consider the tablet as instrumental, although their positive attitude is strongly linked to the expectation of having a more enjoyable learning experience.

44. Computer-Mediated Social Support for Physical Activity: A Content Analysis

Author

Stragier, Jeroen, Mechant, Peter, De Marez, Lieven, and Cardon, Greet

Abstract

Purpose: Online fitness communities are a recent phenomenon experiencing growing user bases. They can be considered as online social networks in which recording, monitoring, and sharing of physical activity (PA) are the most prevalent practices. They have added a new dimension to the social experience of PA in which online peers function as virtual PA partners or supporters. However, research into seeking and receiving computer-mediated social support for PA is scarce. Our aim was to study to what extent using online fitness communities and sharing physical activities with online social networks results in receiving various types of online social support. Method: Two databases, one containing physical activities logged with Strava and one containing physical activities logged with RunKeeper and shared on Twitter, were investigated for occurrence and type of social support, by means of a deductive content analysis. Results: Results indicate that social support delivered through Twitter is not particularly extensive. On Strava, social support is significantly more prevalent. Especially esteem support, expressed as compliments for the accomplishment of an activity, is provided on both Strava and Twitter. Conclusion: The results demonstrate that social media have potential as a platform used for providing social support for PA, but differences among various social network sites can be substantial. Especially esteem support can be expected, in contrast to online health communities, where information support is more common.

45. User Consultation during the Fuzzy Front End: Evaluating Student's Design Outcomes

Author

Conradie, Peter, De Marez, Lieven, and Saldien, Jelle

Abstract

In this paper we evaluate the involvement of a partially blind user as lead user in the early stages of a product redesign during an undergraduate product design-engineering course. Throughout the early stages of product design, or fuzzy front end, there is a high level of uncertainty. End users, with their increased contextual knowledge can play an important role in this process, improving decision-making. Yet limited research has thus far been done on user types for involvement and concept generation efficiency. To study whether end user involvement will impact results, a group of students were given consults from a partially blind end user. Using a panel of four judges, we evaluate the results. We find no significant differences in the feasibility, user value or originality of the concepts created by students who received a user consult. We discuss these findings within the context of user involvement in design engineering education.
