ARCritique: Supporting Remote Design Critique around Mockups

Collaborative presentation and critique of physical artifacts is an essential part of the design process and studio model in many disciplines, such as Industrial Design (ID). In a conventional in-person session, the instructor and other students can communicate fluidly about the artifacts because of the shared space and ease of spatial referencing. However, moving these critique sessions online to support re-mote learning is difficult, as it is challenging to give feedback on a physical object through remote communication tools. While...

Glanceable AR: Evaluations in Authentic Everyday Uses

In the near future, augmented reality (AR) glasses are envisioned to become the next-generation personal computing platform. They could be always on and worn all day, delivering continuous and pervasive AR experiences for general-purpose everyday use cases. However, it remains unclear how we could enable unobtrusive and easy information access without distracting users, while being acceptable to use at the same time. To address this question, we implemented two prototypes based on the Glanceable AR paradigm, a promising way of...

AR Virtual Monitors

The value of multiple, large displays is well established for physical monitors. High-resolution displays with wide aspect ratios can fit large quantities of content side-by-side, allowing users to manage and visualize multiple windows at the same time. These capabilities are essential for productivity tasks. However, the adoption of these devices is not without a cost. Physical monitors require space, lack flexibility, and can become expensive and less portable in large setups. For instance, a student in a classroom or a...

Get the job! An immersive simulation of sensory overload

We designed an immersive experience that simulates sensory issues that are commonly present in conditions such as autism spectrum disorders, PTSD, and schizophrenia. These issues are composed of hypersensitivities, such as perceiving lights brighter than they are, and hyposensitivities, such as not being able to make a distinction over sounds. Our solution was submitted to the 3DUI Contest 2020. We placed the user in an environment where they needed to solve a mundane task, namely, go to a job interview....

Glanceable AR: Information Access Methods for Head-Worn AR Displays

Augmented reality head-worn displays (AR HWDs) have the potential to assist personal computing and the acquisition of everyday information. We propose Glanceable AR, an interaction paradigm for accessing information in AR HWDs. In Glanceable AR, secondary information resides at the periphery of vision to stay unobtrusive and can be accessed by a quick glance whenever needed. We propose two novel hands-free interfaces: "head-glance", in which virtual contents are fixed to the user's body and can be accessed by head rotation,...

Situated Modeling of Large Structures in AR

In recent years, researchers have proposed many mixed reality applications aimed at solving or simplifying problems in the architecture domain. Although designing 3D models digitally is not an unexplored topic, modifying existing methods to fit 3D user interfaces still provides challenges such as maintaining high accuracy while working with more degrees of freedom. For instance, defining a full-scale building model in outdoors using AR (called situated modeling) may require at-a-distance interaction, since navigation may not be easy to perform. We...

Welcome to the 3D Interaction Group

The 3D Interaction (3DI) Group performs research on 3D user interfaces (3D UIs) and 3D interaction techniques for a wide range of tasks and applications. Interaction in three dimensions is crucial to highly interactive virtual reality (VR) and augmented reality (AR) applications to education, training, gaming, visualization, and design. We also conduct empirical studies to understand the effects of immersion in VR and AR, the impact of natural and magic 3D interaction techniques, and usability and user experience in 3D UIs.
