Electronic device with facial sensors

A head-mounted device, comprising:

• a display configured to display an image for viewing from eye boxes;
• a head-mounted housing in which the display is mounted, wherein the head-mounted housing has a ring-shaped light seal that is configured to prevent stray light from interfering with viewing of the image, wherein the light seal has a periphery, and wherein the light seal comprises a compressible member selected from the group consisting of:
• an elastomeric polymer member and a foam member;
• and
• an optical sensor in the light seal within the periphery of the light seal, wherein the optical sensor is configured to measure an amount of pressure exerted by the head-mounted housing on a face.

A head-mounted device, comprising:

• a display configured to display an image for viewing from eye boxes;
• a head-mounted housing in which the display is mounted, wherein the head-mounted housing has a structure and a peripheral ring-shaped light seal that is configured to prevent stray light from interfering with viewing of the image, the peripheral ring-shaped light seal has opposing first and second surfaces, and the second surface is coupled to the structure;
• and
• a motion sensor embedded in the light seal that is configured to detect facial expressions, wherein a portion of the peripheral ring-shaped light seal is interposed between the motion sensor and first surface.
