  • Patent number: 10656708
    Abstract: First media content including text is presented on a display. User expressions of a user, including eye movement, are tracked by an image detector while the user is reading the text of the first media content. User expression data is generated based on the user expressions of the user. A determination can be made as to whether the user expression data indicates that the user gazes at a portion of the text presented on the display for a period exceeding a threshold value. Responsive to determining that the user expression data indicates that the user gazes at a portion of the text presented on the display for a period exceeding a threshold value, one or more actions can be automatically initiated.

  • Patent number: 10656822
    Abstract: 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.
