Currently, researches about automatic documentation tools seldom pay attention to user experience. In attempt to explore how existing works consider user experience of automatic documentation tools and user experience challenges automatic documentation tools are faced with, we qualitatively analyze evaluation sections in 21 papers. We find (1) User experience of automatic documentation tools is usually considered as the supplementary for document quality. (2) Automatic documentation tools are faced with three user experience challenges. Developers do not trust the generated documents. High expectations towards automatic documentation tools also hurt user experience. How developers work and acquire information presents another challenge to the design of automatic documentation tools. Apart from identifying three user experience related challenges, this paper also benefits none SE professionals who are interested in automatic documentation tools by selecting representative papers and summarizing how evaluations are conducted.

Serious concerns have been raised about social media’s and online news outlets’ contribution to a pandemic of misinformation. The sheer volume and tendency of misinformation to exploit people’s cognitive biases have eroded the public’s trust in media outlets, governmental institutions, and the democratic process. With Human-Computer Interaction being at the forefront of designing and developing user-facing computing systems, we bear special opportunities to address these issues and work on solutions to mitigate problems arising from misinformation. This workshop brings together designers, developers, and thinkers across disciplines to redefine computing systems by focusing on technologies and applications that instil and nurture critical thinking in their users. By focusing on the problem of misinformation and users’ cognitive security, this workshop will sketch out blueprints for systems and interfaces that contribute to advancing technology and media literacy, building critical thinking skills, and helping users telling fake from truth.

There is limited infrastructure for providing stress management services to those in need. To address this problem, chatbots are viewed as a scalable solution. However, one limiting factor is having clear definitions and examples of daily stress on which to build models and methods for routing appropriate advice during conversations. We developed a dataset of 6850 SMS-like sentences that can be used to classify input using a scheme of 9 stressor categories derived from: stress management literature, live conversations from a prototype chatbot system, crowdsourcing, and targeted web scraping from an online repository. In addition to releasing this dataset, we show results that are promising for classification purposes. Our contributions include: (i) a categorization of daily stressors, (ii) a dataset of SMS-like sentences, (iii) an analysis of this dataset that demonstrates its potential efficacy, and (iv) a demonstration of its utility for implementation via a simulation of model response times.

It is difficult for people with visual impairments to have balanced nutrition, and one of the reasons is because it is challenging for them to shop for grocery items. In this study, we focused on designing descriptions on grocery items to people with visual impairments to help them with making purchase decisions independently. To identify types of information to be provided, we first conducted an online survey with 73 participants with visual impairments. Then we conducted an in-depth phone interview with eight participants to understand how to better design descriptions for different grocery items. Based on the findings, we provide implications for a camera-based wearable grocery shopping assistance system, which is currently in the prototype stage. This system will help taking the next step in providing effective assistance for people with visual impairments when shopping for groceries.

Within computing education, accessibility topics are usually taught in Human Computer Interaction and Web Design courses. Few have included accessibility in programming courses as an add-on topic. We studied assignments that infuse accessibility into programming topics without impacting the core computing learning objectives. We present two examples, assignments that can be used in Introductory Programming and Object Oriented Programming courses. Both assignments cover accessibility in addition to the primary computing topic taught. We included the two assignments in two courses for two semesters, conducting surveys and interviews to understand the impact of the assignments on students’ learning of accessibility and computing. Our findings show this approach has potential to satisfy accessibility and programming learning objectives without overwhelming the students, though more work is needed to make sure that students are clear on the relationship between the assignments and technical accessibility knowledge.

The HCI Education Community of Practice (CoP) has grown considerably over the past few years, starting with the HCI Living Curriculum workshop at CHI 2018 and continuing through to the EduCHI symposia at both CHI 2019 and CHI 2020. Central to the growth of the CoP has been two parallel efforts: creating channels to discuss issues pertinent to HCI education and providing a platform for sharing HCI curricula and teaching experiences. To continue this progress, we are organizing EduCHI 2021, the 3rd Annual Symposium on HCI Education. EduCHI 2021 will be held virtually and will feature interactive discussions about HCI education trends, curricula, pedagogies, teaching practices, and current and future challenges facing HCI educators.

Passively consuming digital social media content often precludes users from mindfully considering the value they derive from such experiences as they engage in them. We present a system for using Twitter that requires users to continuously turn a hand crank to power their social media screen. We evaluate the device and its effects on how users value Twitter with 3 participants over 3 weeks, with the middle week of Twitter usage directed exclusively through our system. Using our device caused a dramatic decrease in Twitter usage for all participants, which either persisted or rebounded in the post-intervention week. Our analysis of diary studies and qualitative interviews surfaced three themes indicating shifting focus on content, shifting awareness about the role of social media, and new social dynamics around content-sharing.

In the field of sports, visually impaired spectators are unfortunately at a disadvantage in terms of understanding the precise developments of a game. To provide such information to them, making play-by-play announcements of the live coverage of the game is the best approach; however, this is infeasible as it is difficult to employ a professional commentator for every game. Therefore, this study proposes a blind football play-by-play system, combining a tactile graphic display function and a position acquisition function, to aid visually impaired spectators understand game developments. To conduct a basic study, an experimental system was developed herein, which detects the positions of the players and ball using image processing technology and deep learning, and shows these positions via a refreshable tactile display. The validity of the proposed system was then established through subjective experiments. This system provides a rich user experience to the spectators as well as being a powerful feedback tool to the players. Moreover, an audio–tactile graphic system, which can be used to overcome tactile cognitive limitations, can be implemented as an application of the system in the future.

Eye movement recording has been extensively used in HCI and offers the possibility to understand how information is perceived and processed by users. Hardware developments provide the ubiquitous accessibility of eye recording, allowing eye movements to enter common usage as a control modality. Recent A.I. developments provide powerful computational means to make predictions about the user. However, the connection between eye movements and cognitive state has been largely under-exploited in HCI. Despite the rich literature in psychology, a deeper understanding of its usability in practice is still required. This virtual EMICS workshop will provide an opportunity to discuss possible application scenarios and HCI interfaces to infer users’ mental state from eye movements. It will bring together researchers across disciplines with the goal of expanding shared knowledge, discussing innovative research directions and methods, fostering future collaborations around the use of eye movements as an interface to cognitive state.

Effective communication of genetic risk is increasingly important for prevention and treatment of hereditary cancer syndromes. Many individuals do not have access to genetic counselors, or lack the ability to understand and act on genetic risks, due to the complexity of the information. Automated approaches that incorporate animated pedagogical conversational agents may address these barriers. We describe a pedagogical agent that functions in the role of a virtual genetic counselor that discusses hereditary breast cancer risk and motivates women to obtain breast cancer screening. We report the design and evaluation of two prototypes of the virtual counselor. Our results demonstrate the feasibility of this approach, and the effectiveness in improving breast cancer genetics knowledge, by adapting the virtual counselor's pedagogical strategies to an individual's comprehension based on dynamic assessments and preferences.
