Research Areas: augmented reality, wearable technology, collaborative and social computing, information visualization and visual analytics, and design of novel interaction techniques

About

Besides his bachelor degree in music theory from the University of Calgary, Barrett Ens also holds a BSc in computer science from the University of Manitoba where he founded the hUManitech student group for exposing new students to HCI. Barrett is currently researching spatial interfaces for head-worn displays. His research draws from diverse areas including augmented reality, wearable technology, collaborative and social computing, information visualization and visual analytics, and design of novel interaction techniques. By bringing together knowledge from these areas, Barrett aims to better understand the relevant human factors for developing future computing interfaces that blend naturally into both our physical and social environments.
