Wrist tracking devices

Abstract:

A head-mountable device can be operated with devices worn on wrists, arms, hands, and/or other limbs of a user. Such devices can provide indicators that allow a head-mountable device to determine both an identity and a characteristic (e.g., position, orientation, distance, etc.) of the devices and therefore the user. The information regarding the tracking devices and/or the hands can be used to produce a virtual representation of the hands or otherwise be used to receive and interpret gestures as user input. The devices that facilitate such tracking can be worn in a variety or arrangements depending on whether the tracking is to be performed. As such, they can be compactly stored in a manner that allows them to be readily accessible for deployment.
