Exploration strategies for tactile graphics displayed by electrovibration on a touchscreen
- We conducted experiments with human participants to investigate the recognition rate and time of five basic tactile shapes (triangle, square, pentagon, ...
Advancements in surface haptics technology have given rise to the development of interactive applications displaying tactile content on touch surfaces such as images, signs, diagrams, plots, charts, graphs, maps, networks, and tables. ...
Evaluating the effect of displaying team vs. individual metrics on team performance
- A 3-person team had persistent feedback based on the team, the individuals, or both.
This work explores the assessment dimension of persistent feedback to a team, i.e., how presenting feedback based on individual scores vs. team scores vs. both (I&T) affects team performance and team dynamics of a three-person team. ...

- A novel manually annotated Alzheimer's disease dataset for low resource language i.e., Nepalese, consisting of 168 Alzheimer's disease and 98 control normal ...
Alzheimer's disease (AD) is considered as progressing brain disease, which can be slowed down with the early detection and proper treatment by identifying the early symptoms. Language change serves as an early sign that a patient's ...
“I felt her company”: A qualitative study on factors affecting closeness and emotional support seeking with an embodied conversational agent
- The ECA's physical characteristics, conversational ability, rapport building behaviours, and program errors, influenced feelings of closeness towards it.
Embodied conversational agents (ECAs) show promise for use as companions in emotional support applications, although real world uptake can be low. Incorporating closeness building techniques to interactions may improve engagement. ...

- We present the first user study evaluating interactions using facial expressions in virtual reality.
Virtual Reality (VR) interfaces provide an immersive medium to interact with the digital world. Most VR interfaces require physical interactions using handheld controllers, but there are other alternative interaction methods that can ...
Modeling and mitigating human annotation errors to design efficient stream processing systems with human-in-the-loop machine learning
- Study of human annotation task in hybrid stream processing systems.
- Presenting ...
High-quality human annotations are necessary for creating effective machine learning-driven stream processing systems. We study hybrid stream processing systems based on a Human-In-The-Loop Machine Learning (HITL-ML) paradigm, in which ...
