Personalized Recommendation of PoIs to People with Autism

The suggestion of Points of Interest to people with Autism Spectrum Disorder (ASD) challenges recommender systems research because these users' perception of places is influenced by idiosyncratic sensory aversions which can mine their experience by causing stress and anxiety. Therefore, managing individual preferences is not enough to provide these people with suitable recommendations. In order to address this issue, we propose a Top-N recommendation model that combines the user's idiosyncratic aversions with her/his preferences in a personalized way to suggest the most compatible and likable Points of Interest for her/him. We are interested in finding a user-specific balance of compatibility and interest within a recommendation model that integrates heterogeneous evaluation criteria to appropriately take these aspects into account. We tested our model on both ASD and "neurotypical" people. The evaluation results show that, on both groups, our model outperforms in accuracy and ranking capability the recommender systems based on item compatibility, on user preferences, or which integrate these two aspects by means of a uniform evaluation model

RECIPE: How to Integrate ChatGPT into EFL Writing Education

The integration of generative AI in the field of education is actively being explored. In particular, ChatGPT has garnered significant interest, offering an opportunity to examine its effectiveness in English as a foreign language (EFL) education. To address this need, we present a novel learning platform called RECIPE (Revising an Essay with ChatGPT on an Interactive Platform for EFL learners). Our platform features two types of prompts that facilitate conversations between ChatGPT and students: (1) a hidden prompt for ChatGPT to take an EFL teacher role and (2) an open prompt for students to initiate a dialogue with a self-written summary of what they have learned. We deployed this platform for 213 undergraduate and graduate students enrolled in EFL writing courses and seven instructors. For this study, we collect students' interaction data from RECIPE, including students' perceptions and usage of the platform, and user scenarios are examined with the data. We also conduct a focus group interview with six students and an individual interview with one EFL instructor to explore design opportunities for leveraging generative AI models in the field of EFL education

Specializing social networking services to support the independence of adolescents and adults with autism

Many individuals with autism manifest problems in transitioning to adulthood due to social impairments, communication difficulties, and rigid behaviors. One of those challenges is developing a robust and sufficiently large network of people who can provide advice about a variety of everyday situations. In this dissertation, I investigate ways of supporting adolescents with high functioning autism in navigating their everyday life through specializing social networking services (SNSs). A series of studies were conducted to identify opportunities for the design and use of a specialized SNS to foster the independence. The results demonstrates SNS can support some adolescents and adults with autism in increasing the independence by 1) facilitating the asking of a variety of online networks beyond a primary caregiver; and 2) allowing acquisition of rapid, direct, and informational advice with crowdsourcing. Drawing on several formative studies and investigations, I synthesized design guidelines for inquir.us, a specialized hybrid social question-and-answer (Q&A) platform with features for scaffolding question creation and crowdsourcing answers. Through the initial evaluation of inquir.us, I examined the Q&A behavior of individuals with autism on this platform and identified both opportunities and barriers to adoption in the context of supporting transition skills for the independence. The contributions of this thesis are: (1) a rich description of challenges and opportunities related to attaining independent life using SNSs; (2) empirical studies of individuals with autism’s online Q&A behavior; (3) design implications for designing a specialized SNS facilitating the Q&A interactions; and (4) the design and exploratory study of a social Q&A platform in the real world.Ph.D

Understanding University Students’ Experiences, Perceptions, and Attitudes Toward Peers Displaying Mental Health–Related Problems on Social Networking Sites: Online Survey and Interview Study

BackgroundCollege students’ mental health is at an all-time low. Students are increasingly disclosing their vulnerable, stigmatizing experiences on online social networking sites (SNSs). Peer support facilitated by SNSs can play a crucial role for the students in coping with mental health–related problems. Thus, it is imperative to understand how university students form perceptions, attitudes, and behaviors toward their peers who are dealing with mental health problems. ObjectiveThis study aimed to provide a better understanding of how college students recognize, perceive, and react to signs of mental health problems in their peers on SNSs. Our ultimate goal in this study was to inform the design of SNSs that can facilitate online peer support. MethodsWe conducted surveys with 226 students as well as semistructured interviews with 20 students at six universities in South Korea. ResultsOf the 226 survey respondents, 150 (66.4%) reported that they recognized signs of a mental health problem on their friends’ SNS posts. However, a considerable number of respondents (62/150, 41.3%) were reluctant to offer support, even when they had identified friends who were at risk; this reluctance was due to a lack of knowledge or confidence and their desire to maintain a distance from at-risk peers to save their identity from stigmatization and to avoid emotional contagion online. ConclusionsDrawing on these results, we provide implications that could explain the construction of students’ perceptions regarding their peers’ mental health problems. We also provide design proposals for SNSs to serve as platforms that facilitate just-in-time and adaptive support exchanges among peers while mitigating stigma-related concerns

Designing for Self-Tracking of Emotion and Experience with Tangible Modality

Self-tracking technologies have been developed to understand the self. Emotions are critical to understanding one???s daily life; however, tracking the emotion is challenging due to the implicit form of data. In this paper, we introduce MindTracker, an approach for tracking emotion through a tangible interaction with plasticine clay. We explored the benefits and challenges of MindTracker via a two-week data collection study with 16 college students as well as via interviews with three clinical mental health experts. MindTracker is designed for users to craft a form that represents emotion using clay and to describe the experience that evokes the emotion using a diary. We found that the tangible modality of MindTracker motivated the participants to express various aspects of emotions. In addition, MindTracker???s data collection and reflection process could have therapeutic properties, such as expressive therapy, selfsoothing, and emotional self-regulation. We conclude this paper by discussing the design features of emotion-tracking tools and opportunities to use MindTracker to promote mental health

MindNavigator: Exploring the stress and self-interventions for mental wellness

Mental wellness is a desirable health outcome for students. However, current personal informatics systems do not adequately support students in creating concrete mental health-related goals and turning them into actionable plans. In this paper, we introduce MindNavigator - a workshop in which groups of college students were invited to generate behavioral change goals to manage daily life stress and practice personalized interventions for two weeks. We describe the manner in which participants identified both stressors and pleasures to create actionable, engaging, and open-ended behavioral plans that aided in stress relief. We found that the social nature of the workshop helped participants understand themselves and execute self-intervention in new ways. Through this practice, we build on prior studies to propose an analytical framework of personal informatics for mental wellness

AESTHETIC PRODUCT INTERACTION: THE NECESSITY OF CONSISTENCY BETWEEN FUNCTION & EMOTION

We investigate the application of aesthetic stimuli's influence on emotional response during product interaction; implications for novel yet acceptable product experiences. Adopting a research-through-design approach, three tape-dispenser products were designed. Together with a control, the dispensers offered visual and auditory stimulation during product use. Results indicate the importance of consistency between function and stimulus for elicitation of positive response towards novel aesthetic interventions. User profiles also appeared to implicate response to aesthetic stimuli

Design Requirements for Ambient Display that Supports Sustainable Lifestyle

People are ready to change themselves to adopt more eco-friendly habits such as conserving electricity when they are aware of the possible problems of their lifestyle. In this sense, ambient display, which users experience occasionally without its interfering with their primary tasks, is well suited to provide the feedback of their personal activities in a more subtle manner than direct information presentation. We present the results of user studies with two ambient displays in different visualization styles. Participants showed diverse usage behaviors of ambient displays according to their motivational level of sustainable lifestyle. In addition, iconic metaphor of eco-visualization can trigger more emotional attachment while indexical representation helps retrospective functions. Finally, we suggest design requirements for ambient displays that support different stages of persuasion from raising awareness to motivating to change behaviors and to maintaining desired habits

Design Constraints and Their Influence upon Design Outcome

Background: The Effect of two design constraints, ergonomic and aesthetic, on conceptual design ideation and development was investigated. The chosen constraints were selected as experimental conditions to understand the influence of design constraints more generally on concept design. Methods: Workshops were held with participant designers who provided the two constraints (ergonomics and aesthetics). Design outcomes were then assessed by both a sample of potential users and design experts. Results: The results indicated that ergonomic, rather than aesthetic, constraints resulted in radically new ideas. Aesthetic outcomes indicated a highly figurative process, resulting in appropriate, yet less novel solutions. Critical function failure was also identified in ergonomic derived outcomes. Conclusions: The provision of ergonomic design constraints provided a foundation for the emergence of more novel product design solutions. However, aesthetic derived concepts were assessed as more appropriate in terms of both form and function. The appropriation of ergonomic constraints may provide greater scope for novel design solutions but only if functional expectations are satisfied. Aesthetic design constraints stimulated analogous and metaphoric design approaches. Thus, the results indicate how the provision of differing constraints implicated design outcomes
