Case studies

XRC Toolkit

The XRC Toolkit is a collection of tools and 3D interaction techniques, developed by the XR Collaboratory, to accelerate AR/VR prototyping. These modular, reusable packages are used across all our prototyping activities, including research collaborations and student projects.
Case study coming soon.
XRC Designer

The XRC Designer is a design tool for head-mounted displays. The project provides a sandbox environment for 3D interaction designers at the XR Collaboratory, by enabling the deployment of interaction technique prototypes to a functioning application.
Case study coming soon.
