SYSTEMS, DEVICES, AND METHODS FOR INTERACTING WITH CONTENT DISPLAYED ON HEAD-MOUNTED DISPLAYS

摘要

Systems, devices, and methods that enable sophisticated and inconspicuous interactions with content displayed on a head-mounted display are described. A head-mounted display includes an eye-tracker and the user also carries/wears a wireless portable interface device elsewhere on their body, such as a ring. The wireless nature of the portable interface device enables a small and unobtrusive form factor. The portable interface device includes an actuator that, when activated by the user, causes the portable interface device to wirelessly transmit a signal (e.g., a radio frequency signal or a sonic signal). A selection operation performed by the user is defined as the user activating the actuator of the portable interface device while the user is substantially concurrently gazing at a displayed object (as detected by the eye-tracker). In response to the selection operation, the head-mounted display displays a visual effect to the user.
