With augmented virtual information being pervasive and continuous-present, they could become overwhelming, distract and occlude users' view of the real world. In this project, we propose Glanceable AR, an interaction paradigm for information acquisition in AR HDWs. Inspired by existing work in peripheral awareness and calm technology, in Glanceable AR, virtual information stays at the peripheral vision to stay unobtrusive, but can be quickly accessed through a glance whenever needed.

We propose two interfaces:
(1) Gaze-Summon: virtual information is represented as translucent visual targets residing at the edge of the AR display so prevent occlusion. Users can summon the virtual information into the field of view by glancing at these targets for half a second.
(2) Head-Glance: virtual information is body-fixed and resides at the periphery of vision to ensure a clear forward vision. When the users only turn their head to one side of their periphery, they could access the virtual information.
