In this workshop, we will explore the emergent methodological space of social media based HCI design and research. We will gather scholars and practitioners from different areas within HCI to discuss how social media platforms might support their practice. Through short presentations, open discussions, and design-led activities, we will examine the affordances of existing social media platforms and speculate future developments in this methodological space. The outcome of the workshop will be an interactive data visualization of existing social media platforms, their main characteristics, and their affordances for HCI design and research. Overall, we will begin to characterize the methodological space of social media based HCI design and research, setting the foundation for future developments in this space.

Mergers and acquisitions pose complex organizational and technical challenges. A user-centered approach can help ensure the success of a merger. By prioritizing the management of user expectations, by addressing change aversion and by ensuring users feel heard, a merger cannot only be made more successful, but also be perceived as a positive change by end users. This case study describes and discusses the user-centered approach taken to successfully merge two established online LaTeX editors: Overleaf and ShareLaTeX. A mixed methods approach was used to simultaneously ensure broad coverage of the user base (quantitative; relevant because these were established products) and also in-depth understanding of their issues, opinions and motivations (qualitative; relevant to making informed design decisions). This user-centered approach was successful in helping the company to set a path for the merger, to adapt in the face of new data, and to create the foundation for sustained growth.

Adjusting the balance between the player’s game skill and the difficulty level is one of the most important factors to improve the player’s engagement. However, it is still quite rare to find works that aim to straightly control the subjective difficulty perceived by the player. Our research question is whether or not it is possible to control the perceived difficulty just by adding enemy objects that do not raise the actual difficulty level. To investigate this issue, we designed a simple shooting game with two ‘fake enemy bullets’: Unreachable Bullets and Non-collisionable Bullets, which do not damage the player character. The experiment suggests that the non-collisionable bullet can efficiently increase the perceived difficulty level but the unreachable bullet does not. Such a study in novel techniques that can control the perceived difficulty without changing the actual difficulty could contribute to both research and practices in game design.

Research on migration (both internal and external, voluntary and forced) has been an emergent domain in HCI and related disciplines over the past decade. However, as the number of migrants has been increasing over the last two decades, coupled with various growing global affairs, new challenges encountered by diverse types of migrants (e.g. international students, migrant workers) keep arising, and research on mobility gets entangled with many broader social and political issues. Hence, migration can no longer be considered as a ‘special case’ for some immigrant and refugee communities, but an everyday reality to hundreds of millions of people worldwide and across diverse socio-economic groups. Therefore, the objectives of this workshop are to (a) build a community with HCI researchers and practitioners involved in different domains, within and beyond migration, to share ideas and exchange expertise, (b) broaden the scope of HCI migration research and identify gaps within this field, and (c) provide a safe space for critical reflection on methodological approaches, research infrastructure, and space boundaries in relation with migration to achieve a better real-world impact.

The population of the developed world is aging. Most websites, apps, and digital devices are used by adults aged 50+ as well as by younger adults, so they should be designed accordingly. This one-part course, based on the presenter's recent book, presents age-related factors that affect older adults’ ability to use digital technology, as well as design guidelines that reflect older adults’ varied capabilities, usage patterns, and preferences.

Breathing exercises reduce stress and anxiety and are commonly implemented in well-being applications. Here, we compare how well three synthetic auditory feedback stimuli (breath, music, and compound) can guide slow and fast breathing. The results indicate that all three feedback types helped participants entrain the target breathing rate, however, the deviation from the target rate was higher for fast compared to slow breathing. Importantly, when target rate was fast, the compound feedback type resulted in a significantly smaller average respiration error and a longer duration close to the target respiration rate and the breath feedback type resulted in a smaller average deviation from target pace compared to music feedback type. The results point towards an advantage of compound and ecological sound stimuli in particular when the target respiration rate is fast.

Advertising networks enable developers to create revenue, but using them potentially impacts user privacy and requires developers to make legal decisions. To understand what privacy information ad networks give developers, we did a walkthrough of four popular ad network guidance pages with a senior Android developer by looking at the privacy-related information presented to developers. We found that information is focused on complying with legal regulations, and puts the responsibility for such decisions on the developer. Also, sample code and settings often have privacy-unfriendly defaults laced with dark patterns to nudge developers’ decisions towards privacy-unfriendly options such as sharing sensitive data to increase revenue. We conclude by discussing future research around empowering developers and minimising the negative impacts of dark patterns.

COVID-19 has resulted in the rapid popularization of video conferencing. A growing number of users have become obligated to find suitable places for video conferencing, but sometimes they inevitably participate in unsuitable conditions such as noisy or too silent public spaces. However, the video conference experience according to the environment users are in has not been sufficiently discussed. In particular, there is no conducted research on the occasions where video conferencing participants feel unable to speak with their voice due to spatial factors and how to address these situations. In this study, we propose a voice output communication aid (VOCA) for video conferencing which allows users to chat without making a sound. We made a technology probe and conducted a user test. Users who feel unable to speak orally could participate more actively with VOCA. Based on the results, we described the effects and potential of VOCA for video conferencing.

Hyperscanning is an emerging method for measuring two or more brains simultaneously. This method allows researchers to simultaneously record neural activity from two or more people. While this method has been extensively implemented over the last five years in the real-world to study inter-brain synchrony, there is little work that has been undertaken in the use of hyperscanning in virtual environments. Preliminary research in the area demonstrates that inter-brain synchrony in virtual environments can be achieved in a manner similar to that seen in the real world. The study described in this paper proposes to further research in the area by studying how non-verbal communication cues in social interactions in virtual environments can affect inter-brain synchrony. In particular, we concentrate on the role eye gaze plays in inter-brain synchrony. The aim of this research is to explore how eye gaze affects inter-brain synchrony between users in a collaborative virtual environment.

Ubiquitous computing systems rely on ubiquitous methods to sense user interactions, which have manifested in our daily environments as physical buttons, switches, sliders, and beyond. These conventional controllers are either wired, which eliminates flexible deployments, or powered by batteries that require user maintenance. Additionally, built-in wireless communications such as Wi-Fi, Bluetooth, and RFID add up to the total cost. All aforementioned constraints prevent truly ubiquitous interactions from intelligent environments such as smart homes, industry 4.0, precision farming, and a wider range of Internet-of-Things (IoT) applications. We present CubeSense, a wireless and battery-free interactive sensing system which encodes user interactions into radar cross section (RCS) of corner reflectors. Through careful designs of corner reflector mechanisms, CubeSense achieves robust accuracies with controllers made of ultra-low-cost plastics and metal films, resulting in a total cost of around only 20 cents per unit.
