Mixed Reality (MR) is especially suited for guidance during physical tasks where individuals work together to perform actions in the real world. In my dissertation, I explore how MR's unique affordances can help us go "beyond being there" and actively support collaborators’ needs to make it easier to provide and receive guidance. I do so using a (human)communication-first approach where I evaluate interaction techniques that prioritize easing the task of communicating over realism.
The dissertation spans a few projects:
Project MaLi > Uncovering the effects of spatial information and automated guidance to task objects.
This project focuses on referencing - the ability to refer to an object in a way that is understood by others. Being crucial for communication during physical tasks, we evaluated two ways of easing the process of referencing in a 2x2 mixed factorial experiment. We also dive into how aspects of referencing can be offloaded to reduce collaborators' need for spatial information. This work is pulished at CHI 2021 (Read the paper, Watch the talk).
Project UnMapped > Exploiting expert's knowledge in collaborative XR. Details to come.
Project Framework > A communication-focused conceptual framework for XR collaboration. Details to come.
