Implementations set forth herein relate to effectuating device arbitration in a multi-device environment using data available from a wearable computing device, such as computerized glasses. The computerized glasses can include a camera, which can be used to provide image data for resolving issues related to device arbitration. In some implementations, a direction that a user is directing their computerized glasses, and/or directing their gaze (as detected by the computerized glasses with prior permission from the user), can be used to prioritize a particular device in a multi-device environment. A detected orientation of the computerized glasses can also be used to determine how to simultaneously allocate content between a graphical display of the computerized glasses and another graphical display of another client device. When content is allocated to the computerized glasses, content-specific gestures can be enabled and actionable at the computerized glasses.
