Vitiligo is a common pigmentary skin disorder. Children with vitiligo are likely to have low self-esteem and fear of social communication. The common treatment of vitiligo for children is physiological, rarely in psychological measures. In this paper, we present ColorGuardian, a new and interesting skin tattoo customization system, to relieve the psychological damage caused by vitiligo to children. The system scans the vitiligo area with the Light Detection and Ranging scanner to generate the 3D skin surface model and obtain the white patches image. Users can design their own tattoos or choose recommended designs that are available in the gallery to match up the pattern and the white patches’ shape through the application that is linked to the system. We evaluate our system through a light usability test and semi-structured interview. The results show that ColorGuardian has positive impacts on children by reducing their feelings of inferiority.

HCI community believes in understanding socio-cultural norms and designing for users’ values - both of which can stem from users’ belief systems. Using stories from my research work in an Islamic context, I make a case for how religion can impact HCI research. In particular, I discuss a) the implications of socio-cultural norms and participants’ belief (e.g. hijab or ’veil’) on HCI research in these settings; b) how religion forms users’ individual and collective values and socio-cultural norms that impact users’ understanding, use, or perception of technologies; and c) how our presumptions about a belief system or our value tensions can impact reporting and viewing of such findings. Thus, HCI needs to look beyond engagement with populations to include the belief systems to understand the interpretations, negotiations, and enactments of these values, their implications on our research, and their results.

Many active people experience physical activity (PA) frequency fluctuation over the year and need to overcome several perceived barriers to PA to remain active. This paper mainly addresses one of these barriers, Seasonal Variability, and its adherent influencing factors on PA maintenance, which has received limited attention in previous self-tracking studies. We followed a Research through Design approach to explore the influence of the seasons on people's PA fluctuations. We were inspired by professional athletes’ seasonal training plan approach, and conceptualized Seasons, a PA self-management tool. We used the tool to gather PA maintenance and fluctuation coping strategies from 10 participants. Our results show that experiencing PA fluctuations is commonplace, especially due to weather conditions, as well as unexpected circumstances. Individuals deploy different strategies to overcome these fluctuations. Our findings lead to recommendations for HCI researchers to consider when designing future PA maintenance tools.

Algorithmically mediated systems and tools are used by workers across the globe. Many of these workers are in low-power positions, where they have little leverage to make demands around transparency, explanation, or terms of use, yet, at the same time rely deeply on these systems for many aspects of their jobs. This tension between little power and high reliance drives the production of intensive algorithmic imaginaries, where workers engage in meaning-making to construct understandings of these systems. Yet, there has been little attention paid to the diversity and ingenuity of algorithmic understandings crafted by the workers. In this workshop, our goal is to bring together researchers and practitioners from across disciplines to create a research agenda, compare vocabularies, and discuss methodologies around this form of “folk tradecraft.” This toolkit will help elicit insights into these phenomena and ultimately build mechanisms by which the labor of algorithmic meaning-making can be respected, understood, and leveraged for system design.

How long is a lifetime of practice in human-computer interaction? In my case, it has been 42 years, almost all of that in IBM Research (with a couple of sabbatical years in the then new Watson Group). Having queued up for access to DEC and Prime machines during my PhD work in the mid 70s, I was positively thrilled when, upon arriving at the T.J. Watson Research Center in 1978, I found a dedicated 3277 “green screen” terminal on my desk attached to a 370 mainframe. Hot-rodded with an onboard character buffer and double speed cursor circuitry, I could fly through writing and coding, personally experiencing the productivity benefits of sub-second response time [1]. Beyond some great hardware (for the time), I also had extraordinary colleagues. I imprinted on the working style of John Gould and Stephen Boies as we built the second hardware iteration of what became the world's first commercial voice mail system and its final manifestation as the messaging system for the 1984 Summer Olympics. In this talk I'll share some of the still relevant behavioral principles of system design we learned in the course of that project [2]. Beyond this, I'll review work in early (pre-Web!) Internet access for schools [3], home shopping [4], Web accessibility [5], and programmer productivity in peta-scale scientific computing [6]. Each project will highlight a barrier to building useful and usable systems, barriers that still persist. More importantly, I'll tell you how we overcame those barriers, giving you something that will, perhaps, be useful in your own work.
在人机交互方面，一生的实践有多长?就我而言，我已经工作了42年，几乎所有的时间都在IBM研究院(除了在当时新成立的沃森集团(Watson Group)休息的几年)。在上世纪70年代中期攻读博士学位期间，我一直在排队使用DEC和Prime机器。1978年，当我到达T.J.沃森研究中心(T.J. Watson Research Center)时，我发现桌子上有一台专用的3277“绿屏”终端，连接着一台370大型机，这让我非常兴奋。借助板载字符缓冲器和双速光标电路，我可以快速编写和编码，亲身体验亚秒级响应时间的生产力优势[1]。除了一些出色的硬件(在当时)，我还有出色的同事。我在John Gould和Stephen Boies的工作方式上留下了深刻的印象，我们建立了世界上第一个商业语音邮件系统的第二次硬件迭代，并最终体现为1984年夏季奥运会的信息系统。在本次演讲中，我将分享我们在该项目过程中学到的一些与系统设计相关的行为原则[2]。除此之外，我将在早期回顾工作(在web之前!)学校[3]、家庭购物[4]、网络可访问性[5]以及peta级科学计算中的程序员生产力[6]的互联网接入。每个项目都将突出构建有用和可用系统的障碍，这些障碍仍然存在。更重要的是，我会告诉你我们是如何克服这些障碍的，给你一些东西，也许对你自己的工作有用。

We present Connected Companion (CoCo), a health tracking wearable that provides users with timely, context-relevant notifications aimed at improving wellness. Traditionally, self-tracking wearables report basic health data such as resting heart rate; these data are visualised and positive behaviours (e.g. exercising often) are encouraged with rudimentary gamification (e.g. award badges) and notification systems. CoCo is the first wearable to combine caffeine, alcohol and cortisol sensors, a context network (which predicts user context), and a wellness model (which establishes per-user wellness measures). Working in tandem these provide users with notifications that encourage discrete behaviours intended to optimise user-wellness per very specific biological and social contexts. The paper describes the (sometimes unexpected) results of a user-study intended to evaluate CoCo's efficacy and we conclude with a discussion about the power and responsibility that comes with attempts to build context-aware computing systems.

The past two decades have seen an increase in the amount of research in the CHI community from South Asia with a focus on designing for the unique and diverse socio-cultural, political, infrastructural, and geographical background of the region. However, the studies presented to the CHI community primarily focus on working with and unpacking the regional contextual constraints (of the users and the infrastructures), thus taking a developmental stance. In this online workshop, we aim to broaden the perspective of the CHI research and community towards the contributions from the region including and beyond development, by bringing together researchers, designers, and practitioners working or are interested in working within these regions on diverse topics such as universal education, global healthcare, accessibility, sustainability, and more. Through the workshop discussion, group design activity, and brainstorming, we aim to provide a space for symbiotic knowledge sharing, and defining shared visions and missions for HCI activities in South Asia for including and moving beyond the development agenda.

The current state of audio rendering algorithms allows efficient sound propagation, reflecting realistic acoustic properties of real environments. Among factors affecting realism of acoustic simulations is the mapping between an environment’s geometry, and acoustic information of materials represented. We present a pipeline to infer material characteristics from their visual representations, providing an automated mapping. A trained image classifier estimates semantic material information from textured meshes mapping predicted labels to a database of measured frequency-dependent absorption coefficients; trained on a material image patches generated from superpixels, it produces inference from meshes, decomposing their unwrapped textures. The most frequent label from predicted texture patches determines the acoustic material assigned to the input mesh. We test the pipeline on a real environment, capturing a conference room and reconstructing its geometry from point cloud data. We estimate a Room Impulse Response (RIR) of the virtual environment, which we compare against a measured counterpart.

Negative thoughts are a widespread everyday experience. Failures to appropriately cope with negative thoughts are related to serious mental health issues, such as depression. Consequently, preventive technology-mediated everyday interventions to support coping with negative thoughts are of interest. One promising platform for mental health applications is personalized virtual reality (VR). We developed an explorative VR prototype based on personally relevant textual messages from email, messengers and alike, which trigger negative thoughts. The prototype presented these messages in VR and allowed to physically manipulate them, for example, by physically punching and trashing them. A qualitative empirical exploration (N=10) revealed a general positive shift in thoughts and emotions after using the prototype, mainly in form of increased relaxation and self-reflection. Based on this and further insights, we derive four themes for VR in mental health, touching upon the importance of personalization, immersion and focus, interaction design and embodiment, as well as, integration into everyday life.

Soft robotics use in haptic devices continues to grow, with pneumatic control being a common actuation source. Typical control systems used, however, rely on a digital on/off control allowing only inflation/deflation at a set rate. This limits the degrees of freedom available when designing haptic experiences. We present an alternative system to allow the use of analog control of the pneumatic waveform profiles to design and experiment with haptic devices, and to determine the optimum wave profile for the desired experience. Using a combination of off-the-shelf components and a user interface, our system allows for rapid experimentation with various pressure levels, and the ability to control waveform profiles in a common format such as attack-sustain-release. In this paper, we demonstrate that by altering the attack and release profiles we can create a more pleasant pulsing sensation on the wrist, and a more continuous sensation for communicating movement around the wrist.
