AR-HMD Multitask Viewing System Concept with a Supporting Handheld Viewport for Multiple Spatially-Anchored Workspaces.

We propose a system concept for Augmented Reality Head-Mounted Display users, which supports multitask viewing with multiple virtual workspaces anchored in the real-world space. Although people encounter multitasking necessities frequently, the native AR HMD and existing interfaces lack measures to visualize multiple sets of spatially-anchored information in parallel. The system separately visualizes two different sets of spatially-anchored information, one on each AR HMD and smartphone, enabling side-by-side multitasking on AR HMD without applying heavy load on users. We implemented a proof-of-concept prototype that allows side-by-side viewing of the two different virtual workspaces. The proposed concept shows promises of multitasking on AR HMD, and future research will develop the system to be fully functional and verified with user studies.
