Patent attributes
A system may include a finger device that is worn on a user's finger. The finger device may serve as a controller for a head-mounted device or other devices in the system. The finger device may have a foldable housing with hinge structures that allow portions of the housing to fold with respect to each other. Magnets or other bistability structures may be used to provide the folding housing with folding bistability. This allows the housing to be placed in a stable unfolded state that releases the finger or a stable folded state in which the housing snaps over the finger and holds the finger device in place. A base may be used to store the finger device for charging. The base may have deployment structures that help place the finger device on the user's finger for use.
