Abstract

Mindless eating, or the lack of awareness of the food we are consuming, has been linked to health problems attributed to unhealthy eating behaviour, including obesity. Traditional approaches used to moderate eating behaviour often rely on inaccurate self-logging, manual observations or bulky equipment. Overall, there is a need for an intelligent and lightweight system which can automatically monitor eating behaviour and provide feedback. In this paper, we investigate: i) the development of an automated system for detecting eating behaviour using wearable Electromyography (EMG) sensors, and ii) the application of such a system in combination with real time wristband haptic feedback to facilitate mindful eating. Data collected from 16 participants were used to develop an algorithm for detecting chewing and swallowing. We extracted 18 features from EMG and presented those features to different classifiers. We demonstrated that eating behaviour can be automatically assessed accurately using the EMG-extracted features and a Support Vector Machine (SVM): F1-Score=0.94 for chewing classification, and F1-Score=0.86 for swallowing classification. Based on this algorithm, we developed a system to enable participants to self-moderate their chewing behaviour using haptic feedback. An experiment study was carried out with 20 additional participants showing that participants exhibited a lower rate of chewing when haptic feedback delivered in forms of wristband vibration was used compared to a baseline and non-haptic condition (F (2,38)=58.243, p<0.001). These findings may have major implications for research in eating behaviour, providing key new insights into the impacts of automatic chewing detection and haptic feedback systems on moderating eating behaviour with the aim to improve health outcomes., Comment: v1: 13 + 12 pages

24. Investigation of virtual worlds as a platform to support healthy aging for older people

Abstract

Due to the aging of the population in recent years, it is becoming essential to find innovative activities to help the increasing older population maintain an active lifestyle and delay the need for institutionalized care. Virtual worlds, which have many potential values such as in providing social engagement, could be used to support older people in this aspect. Despite this, most research and design of virtual worlds today are based on young users and do not coincide well with the interests and requirements of older people. It is therefore necessary to investigate how virtual worlds can be designed to not only meet the needs of older users but also to provide opportunities for social engagement and support healthy aging. In the first stage of the research, a series of studies were carried out with older virtual world users to investigate their characteristics, interests and activities. This includes a qualitative interview study and an empirical study. Older users were able to develop interpersonal relationships in virtual worlds and were interested in activities which made useful contribution to society or those which allowed them to socialize with people who share similar interests. Next, two experiment studies were carried out, the first to investigate age related differences in virtual social interaction and the second to determine how different factors influence the social interaction experience. Factors such as navigation were found to influence social interaction and the study revealed limitations relating to the usefulness of the avatar. The findings from this thesis helps extend our theoretical understanding of the interactions and activities of older people in virtual worlds and how previously identified concepts regarding virtual social interaction relate to older users. In addition, the findings were also applied into guidelines to aid developers in creating better virtual worlds to facilitate social interaction and healthy aging.

42. A Comparison of Empathic Communication Pattern for Teenagers and Older People in Online Support Communities

Author

Siriaraya, Panote, Tang, Caleb, and Ang, Chee Siang

Abstract

This article reports a study that investigated the occurrences of empathy in online support communities for teenagers. Qualitative content analysis with 400 messages from a discussion board about depression was used to identify how empathy was expressed in the specific online communication. Emphasis was also placed on the comparison of this age group to older people, by comparing the results with those from a previous study on empathy in an online support community about depression for older people. Specifically, the analysis focused on the frequencies of the categories of the code scheme, linguistic characteristics of the communication content, the occurring components of empathy, and the roles as well as activities of the members. From our analysis, we concluded that young people exchanged a substantial amount of empathic emotional communication when participating in an online support community, and they communicated on a more personal level compared to older people, who tended to engage in a more formal communication. In addition, teenagers also showed a high level of understanding but lower level of concern compared to older persons when expressing empathy online. (Contains 1 figure, 3 tables, and 3 notes.)
