PaperToPlace - Transforming Instruction Documents into Spatialized and Context-Aware Mixed Reality Experiences

UIST 2023 Paper instructions are a mainstream medium for sharing knowledge. However, consuming such instructions and translating them into activities can be inefficient due to the lack of connectivity with the physical environment. PaperToPlace is a novel workflow comprising an authoring pipeline, which allows the authors to rapidly transform and spatialize existing paper instructions into an MR experience, and a consumption pipeline, which computationally places each instruction step at an optimal location that is easy to read and does not occlude key interaction areas. This is a collaborative project with Adobe Research.

Embodied Exploration - Facilitating Remote Accessibility Assessment for Wheelchair Users with Virtual Reality

ASSETS 2023 Assessing accessibility for wheelchair users can be challenging, due to lack of accessibility details needed for individual users. Embodied Exploration is a VR technique to deliver the experience of a physical visit while keeping the convenience of remote assessment. Embodied Exploration allows wheelchair users to explore high-fidelity digital replicas of physical environments with themselves embodied by avatars, leveraging the increasingly affordable VR headsets.

Towards Visualization of Time–Series Ecological Momentary Assessment (EMA) Data on Standalone Voice–First Virtual Assistants

ASSETS 2022 To explore the potential opportunities for visualizing time-series based EMA data on standalone IVAs, we designed a prototype system, where older adults are able to query and examine the time–series EMA data on Amazon Echo Show — a widely used commercially available standalone screen–based IVA
