ARTEMIS > Designing and evaluating an XR remote guidance system for open surgery and trauma care.

ARTEMIS is a mixed-modality collaborative system geared towards facilitating remote guidance for surgery and trauma care. It was designed and developed in collaboration with the Naval Medical Center at San Diego and evaluated using cadaver studies for a number of trauma procedures. This work is published at CHI 2021 and has been accepted at the journal Surgery (go to project page).

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).

UnMapped > Leveraging expert's knowledge in collaborative XR. 

In this paper, we design UnMapped, an alternative interface for remote experts that combines a live 3D view of the active space within the novice’s environment with a static 3D recreation of the expert’s own workspace to leverage their existing spatial memories within it. We evaluate the impact of this approach on single and repeated use of collaborative MR systems for remote guidance through a comparative study. Our results indicate that despite having a limited understanding of the novice’s environment, using an UnMapped interface increased performance and communication efficiency while reducing experts’ task load. We also outline the various affordances of providing remote experts with a familiar and spatially-stable environment to assist novices. (Read the paper, Watch the talk)
