CHI 2019 will take place in Glasgow, Scotland. This conference and its namesake organization which has been around for 35 years, is TorCHI's "mother organization." The CHI Conference is an annual meeting, which gathers approximately 3,000 participants from around the world who share passion for UX, Usability, and Human Computer Interaction in research and practice, in academia and industry. This TorCHI event will be a preview of the research talks to be given at the conference by Students from University of Toronto's Dynamic Graphics Project (DGP). To be accepted for presentation at CHI is a significant accomplishment, because the worldwide competition for admission is fierce and only a small number of submissions are accepted each year following a rigorous peer review process. Which means, that these projects are exceptional and worthy of worldwide attention for their leading edge technology and innovation.
If you can't make the CHI2019 conference, this is a perfect opportunity to get a peek at the content you will be missing. If you are planning to attend CHI2019, this will give you the chance to see more, so you can experience the remaining 19 parallel tracks with slightly less loss aversion, than you would feel, if you did not see these talented presenters practice their talks and answer tough questions from our TorCHI audience.

HoloDoc: Enabling Mixed Reality Workspaces that Harness Physical and Digital Content
Prior research identified that physical paper documents have many positive attributes, for example natural tangibility and inherent physical flexibility. When documents are presented on digital devices, however, they can provide unique functionality to users, such as the ability to search, view dynamic multimedia content, and make use of indexing. This work explores the fusion of physical and digital paper documents. It first presents the results of a study that probed how users perform document-intensive analytical tasks when both physical and digital versions of documents were available. The study findings then informed the design of HoloDoc, a mixed reality system that augments physical artifacts with rich interaction and dynamic virtual content. Finally, we present the interaction techniques that HoloDoc affords, and the results of a second study that assessed HoloDoc's utility when working with digital and physical copies of academic articles.","keywords":"Mixed reality; Augmented reality; Digital pen input; Reading behavior

"I feel it is my responsibility to stream": Streaming and Engaging with Intangible Cultural Heritage through Livestreaming
Globalization has led to the destruction of many cultural practices, expressions, and knowledge found within local communities. These practices, defined by UNESCO as Intangible Cultural Heritage (ICH), have been identified, promoted, and safeguarded by nations, academia, organizations and local communities to varying degrees. Despite such efforts, many practices are still in danger of being lost or forgotten forever. With the increased popularity of livestreaming in China, some streamers have begun to use livestreaming to showcase and promote ICH activities. To better understand the practices, opportunities, and challenges inherent in sharing and safeguarding ICH through livestreaming, we interviewed 10 streamers and 8 viewers from China. Through our qualitative investigation, we found that ICH streamers had altruistic motivations and engaged with viewers using multiple modalities beyond livestreams. We also found that livestreaming encouraged real-time interaction and sociality, while non-live curated videos attracted attention from a broader audience and assisted in the archiving of knowledge.","keywords":"Livestreaming; intangible cultural heritage; user engagement; social media; cultural preservation

A Lie Reveals the Truth: Quasimodes for Task-Aligned Data Presentation.
Designers are often discouraged from creating data visualizations that omit or distort information, because they can easily be misleading. However, the same representations that could be used to deceive can provide benefits when chosen to appropriately align with user tasks. We present an interaction technique, Perceptual Glimpses, which allows for the transparent presentation of so-called 'deceptive' views of information that are made temporary using quasimodes. When presented using Perceptual Glimpses, message-level exaggeration caused by a truncated axis on a bar chart was reduced under some conditions, but users require guidance to avoid errors, and view presentation order may affect trust. When Perceptual Glimpses was extended to display a range of views that might otherwise be deceptive or difficult to understand if shown out of context, users were able to understand and leverage these transformations to perform a range of low-level tasks. Design recommendations and examples suggest extensions of the technique.

The Breaking Hand: Skills, Care, and Sufferings of the Hands of an Electronic Waste Worker in Bangladesh
While repair work has recently been getting increasing attention in HCI, recycling practices have still remained relatively understudied, especially in the context of the Global South. To this end, building on our eight-month-long ethnography, this paper reports the electronic waste (‘e-waste’, henceforth) recycling practices among the e-waste recycler ( ‘bhangari’) communities in Dhaka, Bangladesh. In doing so, this paper offers the work of the bhangaris through an articulation of their hands and their uses. Drawing from a rich body of scholarly work on social science, we define and contextualize three characteristics of the hand of a bhangari: knowledge, care, and skills and collaboration. Our study also highlights the pains and sufferings involved in this profession. By explaining bhangari work through the hand, we also discuss its implications for design, and its connection to HCI’s broader interest in sustainability.

Integrating Multimedia Tools to Enrich Interactions in Live Streaming for Language Learning
Online language lessons have adopted live broadcasted videos to provide more real-time interactive experiences between language teachers and learners. However, learner interactions are primarily limited to the built-in text chat in the live stream. Using text alone, learners cannot get feedback on important aspects of a language, such as speaking skills, that are afforded only by offering richer types of interactions. We present results from a 2-week in-the-wild study, in which we investigate the use of text, audio, video, image, and stickers as interaction tools for language teachers and learners in live streaming. Our language teacher explored three different teaching strategies over four live streamed English lessons, while nine students watched and interacted using multimodal tools. The findings reveal that multimodal communication yields instant feedback and increased engagement, but its use is dependent on factors such as group size, surroundings, time, and online identity.

How Do One’s Peers on a Leaderboard Affect Oneself?
Leaderboards are a workhorse of the gamification literature. While the effect of a leaderboard has been well studied, there is much less evidence how one's peer group affects the treatment effect of a leaderboard. Through a pre-registered field experiment involving more than 1000 users on an online movie recommender website, we expose users to leaderboards, but different sets of users are exposed to different peer groups. Contrary to what a standard behavioral model would predict, we find that a user's contribution increases when their peer's scores are more dispersed. We also find that decreasing average peer contributions motivates a user to contribute more. Moreover, these effects are themselves mediated by group size. This sheds new light on existing theories of motivation and demotivation with regards to leaderboards, and also illustrates the potential of using personalized leaderboards to increase contributions.
