Activated Motivation: An Opportunity for HCI Research?
Wallace, James (University of Waterloo, 2022-02-24)Self-Determination Theory [7, 13, 14] is a decades-old, widely-validated macro-theory that describes human motivation. Generally, it defines motivation on a spectrum ranging from amotivation, or a lack of motivation, to ... -
Advancing Public Health through Computational Thematic Analysi
Gauthier, Robert P.; Wallace, James (Association for Computing Machinery (ACM), 2023-04-28)Public health researchers often use thematic analysis to develop human understandings of discussions from online communities. However, these analyses are difficult to conduct because of their and a general lack of programming ... -
Agency and Amplification: A Comparison of Manual and Computational Thematic Analyses by Public Health Researchers
Gauthier, Robert; Pelletier, Catherine; Carrier, Laurie-Ann; dionne, Maude; Dubé, Ève; Meyer, Samantha B.; Wallace, James (ACM, 2023-01)Computational techniques offer a means to overcome the amplified complexity and resource-intensity of qualitative research on online communities. However, we lack an understanding of how these techniques are integrated by ... -
The Computational Thematic Analysis Toolkit
Gauthier, Robert; Wallace, James (ACM, 2022-01)As online communities have grown, Computational Social Science has rapidly developed new techniques to study them. However, these techniques require researchers to become experts in a wide variety of tools in addition to ... -
Creating Your Bubble: Personal Space On and Around Large Public Displays
Wallace, James R.; Iskander, Nancy; Lank, Edward (ACM, 2016-05)We describe an empirical study that explores how users establish and use personal space around large public displays (LPDs). Our study complements field studies in this space by more fully characterizing interpersonal ... -
Design and Evaluation of Technologies for Informed Food Choices
Costa Bomfim, Marcela; Wong, Erin; Liang, Paige; Wallace, James (ACM, 2022-10-04)Technology increasingly mediates our everyday interactions with food, ranging from its production and handling to the experience of preparing and eating it with friends and family. However, it is unclear whether these ... -
Effect of Bezel Presence and Width on Visual Search
Wallace, James R.; Vogel, Daniel; Lank, Edward (Association for Computing Machinery, 2014-06)We investigate how the presence and width of interior bezels impacts visual search performance across tiled displays. In spite of a potential benefit from structured segmentation, we do not find significant differences in ... -
The effect of interior bezel presence and width on magnitude judgement
Wallace, James R.; Vogel, Daniel; Lank, Edward (Canadian Human-Computer Communications Society, 2014-05)Large displays are often constructed by tiling multiple small displays, creating visual discontinuities from inner bezels that may affect human perception of data. Our work investigates how bezels impact magnitude judgement, ... -
Felines, Foragers, and Physicists: Supporting Scientific Outreach with Multi-Surface and Multi-Space Games
Cheung, Victor; Wallace, James R. (Association for Computing Machinery, 2016-11-06)We describe the design, development, and deployment of two scientific outreach games to support an open house event at an Institute for Quantum Computing (IQC) by an 11-member team of academics and practitioners over a ... -
Food Literacy while Shopping: Motivating Informed Food Purchasing Behaviour with a Situated Gameful App
Bomfim, Marcela C.C.; Kirkpatrick, Sharon I.; Nacke, Lennart; Wallace, James R. (ACM, 2020-04-25)Establishing healthy eating patterns early in life is critical and has implications for lifelong health. Situated interventions are a promising approach to improve eating patterns. How- ever, HCI research has emphasized ... -
Group vs Individual: Impact of TOUCH and TILT Cross-Device Interactions on Mixed-Focus Collaboration
Homaeian, Leila; Goyal, Nippun; Wallace, James R; Scott, Stacey (Association for Computing Machinery, 2018-04-28)Cross-device environments (XDEs) have been devel-oped to support a multitude of collaborative activities. Yet, little is known about how different cross-device in-teraction techniques impact group collaboration; in-cluding ... -
"I Will Not Drink With You Today": A Topic-Guided Thematic Analysis of Addiction Recovery on Reddit
Gauthier, Robert; Costello, Mary Jean; Wallace, James (ACM, 2022-04)Recovery from addiction is a journey that requires a lifetime of support from a strong network of peers. Many people seek out this support through online communities, like those on Reddit. However, as these communities ... -
Increasing Passersby Engagement with Public Large Interactive Displays: A Study of Proxemics and Conation
GHARE, MOJGAN; Pafla, Marvin; Wong, Caroline; Wallace, James R.; Scott, Stacey (Association for Computing Machinery, 2018-11-19)Prior research has shown that large interactive displays de- ployed in public spaces are often underutilized, or even un- noticed, phenomena connected to ‘interaction’ and ‘display blindness’, respectively. To better ... -
Joint Action Storyboards: A Framework for Visualizing Communication Grounding Costs
Homaeian, Leila; Wallace, James, R.; Scott, Stacey D. (ACM, 2021)Building and maintaining common ground is vital for effective collaboration in CSCW. Moreover, subtle changes in a CSCW user interface can significantly impact grounding and collaborative processes. Yet, researchers and ... -
Merlynne: Motivating Peer-to-Peer Cognitive Behavioral Therapy with a Serious Game
Chan, Tina; Gauthier, Robert; Suarez, Ally; Sia, Nicholas F.; Wallace, James R (ACM, 2021-09)Human-Computer Interaction researchers have explored how online communities can be leveraged for peer support, but general disinterest and a lack of engagement have emerged as substantial barriers to their use in practice. ... -
Nature vs. Stress: Investigating the Use of Biophilia in Non-Violent Exploration Games to Reduce Stress
Reetz, Adrian; Valtchanov, Deltcho; Barnett-Cowan, Michael; Hancock, Mark; Wallace, James R (ACM, 2021)Games hold the potential to help many address health-related issues such as chronic stress. We investigated the use of biophilia, an affective response to nature grounded in the psychology literature, as indirect physiological ... -
Pirate Bri’s Grocery Adventure: Teaching Food Literacy through Shopping
Bomfim, Marcela C.C.; Wallace, James (ACM, 2018-04)Food Literacy (FL) is associated with the improvement of autonomy and confidence around food, healthier dietary intake, and chronic disease prevention. However, to date, behaviour change research at CHI has focused on ... -
