“…Although SUS was originally designed to assess perceived usability as a single attribute, Lewis and Sauro [ 53 ] found that there are actually two factors in SUS. Eight of the questions reflect a usability factor and two reflect a learnability factor [ 54 ]. Figure 17 and Figure 18 show results per participant of the different SUS dimensions (Overall Score, Usability Dimension, Learnability Dimension) and the distribution of the aggregated results considering all tested tasks.…”

Obesity is a preventable chronic condition that, in 2016, affected more than 1.9 billion people globally. Several factors have been identified that have a positive impact on long-term weight loss programs such as personalized recommendations, adherence strategies, weight and diet follow-up or physical activity tracking. Recently, various applications have been developed which help patients to self-manage their condition. These apps implement either one or some of these identified factors; however, there is not a single application that combines all of them following a holistic approach. In this context, we developed the OBINTER platform, which assists patients during the weight loss process by targeting user engagement during the longer term. The solution includes a mobile application which allows users to fill out dietetic questionnaires, receive dietetic and nutraceutical plans, track the evolution of their weight and adherence to the diet, as well as track their physical activity via a wearable device. Furthermore, an adherence strategy has been developed as a tool to foster the app usage during the whole weight loss process. In this paper, we present how the OBINTER approach gathers all of these features as well as the positive results of a usability testing study performed to assess the performance and usability of the OBINTER platform.

“…Comparing the results on system usability between the two studies, we find that the system with Gaze-Guided Narratives (condition D) obtained an average SUS score of 82.81 (SD = 12.06) in the real world and 69.33 (SD = 12.31) in the CAVE (see section 4). An average SUS score above 80 has been suggested to be considered as "pretty good", while a score of 66 could be considered as average [56]. One possible explanation for this difference could be the higher degree of immersion in the real world.…”

“…Regarding the questionnaire, we use the Likert Scales [25], a series of statement to which the respondents rate their level of agreement on a 5-point scale. The rankings from 1 to 5 indicate from "Strongly Disagree" to "Strongly Agree".…”

“…What's more, to avoid the "social desirability bias" [25], we collect the posttest data in a way that the evaluator did not see the responses until the participant has left, and we also made the survey itself anonymous to elicit more honest reactions. Data collected in the survey are expressed by histogram in percentage.…”

Leisure Food: Derive Social and Cultural Entertainment through Physical Interaction with Food

Food is not simply a source of nutrition, but also a symbolic medium for social bonds and entertainment. Beyond this, food is common artefact across cultures, embedded with internal cultural value and identity. This paper presents the notion of "Leisure Food", which explores the roles of mundane food in deriving social and cultural entertainment from people's interaction with physical food. We focus on the application of culturally based food experiences as a gateway for enriched and profound entertainment, through maximizing the physical, social and cultural affordances of food using technologies. From this notion, we developed two prototypes based on the positive interactions that people have as they eat and prepare food in their everyday lives and also extend them to remote situations. The preliminary user study demonstrates that these two prototypes can enhance the level of social engagement and culture recollection experience through the new designed forms of physical food-mediated interaction, which verified the proposed features regarding "Leisure Food".
