We are a human-computer interaction research lab contributing new methods, tools, and technologies for creating novel interactive systems and technologies.

We have a history of building and studying next-generation user interfaces, involving touch, gesture, speech, multi-modal, multi-device interactions, and now virtual, augmented, and mixed reality interfaces. When studying these forms of interfaces, our focus is on improving both the designers’ and the end-users’ experience through novel ways of creating and using them.

We thank our sponsors for supporting the research below.

Current Research Topics

Our research group is currently pursuing three major research themes:

  • Democratizing XR development: In a series of new systems, we are exploring different ways of enabling designers and domain experts to create new AR/VR experiences without significant training in 3D programming, animation, or modeling.
  • Instructional XR experiences: As part of our involvement in the U-M wide XR initiative, we are investigating new techniques and tools for creating immersive instructional materials making use of XR technology to facilitate training and learning.
  • Safe and accessible XR applications: We are constantly exploring new, promising applications of XR. Our current efforts are focused on improving collaboration, and making XR more accessible and safe, by incorporating accessibility and privacy principles into design.

Recent Work

Here, we summarize recent contributions to ACM CHI, the premier conference in the human-computer interaction field:

  • Virtual production of immersive lectures: With XRStudio, we created a virtual production and live streaming system for immersive instructional experiences. XRStudio equips instructors interested in using VR for teaching with tools and infrastructure to record or live stream lectures in VR. Students can access these VR lectures with or without VR devices using different output channels including mixed reality capture, 3D desktop, mobile AR, or fully immersive VR.
  • Mixed reality user studies: With MRAT, we created a mixed reality analytics toolkit, designed to support user evaluations on AR/VR devices, eliciting a diverse set of requirements and presented general concepts and techniques to collect, pre-process, and visualize mixed reality user data.
  • Collaborative immersive authoring: With XRDirector, we created a role-based, multi-user immersive authoring system that adapts roles familiar from filmmaking to coordinate multiple AR/VR designers and characterize the issues related to spatial coordination.
  • Key barriers to entry for novice XR creators: We conducted an interview study with 21 participants elaborating on their practices and challenges making use of current XR technologies and tools and explored opportunities for better end-user programming support.

Earlier Research

Over the first three years at U-M, the lab has worked at the forefront of cross-device interfaces, multi-modal interaction, and AR/VR. Our systems research contributions include ProtoAR [CHI’18] and 360proto [CHI’19] for rapid prototyping of AR/VR interfaces using cross-device authoring, 360Anywhere [EICS’18] for 360 video based collaboration using mixed reality, GestureWiz [CHI’18] for using Wizard of Oz and crowdsourcing in gesture design and recognition tasks. Using the knowledge from building these systems, the lab has also been working on conceptual frameworks and new ways of thinking about future interfaces’ design through contributions such as What is Mixed Reality? [CHI’19 Best Paper Honorable Mention], The Trouble with AR/VR Authoring Tools [ISMAR’18 Adj.], Playing the Tricky Game of Toolkits Research [CHI’17 HCI.Tools Workshop], and studies on creating cross-device AR experiences resulting in XD-AR [EICS’18 Best Paper Award] as well as user-driven design principles for gesture representations [CHI’18].

We keep an archive of our previous research here.
