Abstract
A device, such as a head-mounted device (HMD), may include a frame and a plurality of mirrors coupled to an interior portion of the frame. An imaging device may be coupled to the frame at a position to capture images of an eye of the wearer reflected from the mirrors. The HMD may also include a mirror angle adjustment device to adjust an angle of one or more of the mirrors relative to the imaging device so that the mirror(s) reflect the eye of the wearer to the imaging device.
Claims20
A head-mounted device comprising:
- a plurality of mirrors coupled to an interior portion of a frame;
- a first imaging device coupled to the frame at a position to capture images of the plurality of mirrors;
- and
- a mirror angle adjustment device to adjust an angle of at least one of the plurality of mirrors relative to the first imaging device so that the at least one of the plurality of mirrors reflects a first eye to the first imaging device,
- wherein the plurality of mirrors are disposed within a field of view of the first imaging device such that the first imaging device captures images of the plurality of mirrors, the plurality of mirrors each directly reflecting the first eye.
2 more elements
A device comprising:
- a front frame;
- a plurality of mirrors coupled to an interior portion of the front frame to reflect a first eye of a user of the device;
- an arm coupled to the front frame;
- a first imaging device coupled to the arm at a position to capture an image of the plurality of mirrors;
- and
- a light source coupled to the interior portion of the front frame to illuminate the first eye of the user,
- wherein the plurality of mirrors are disposed within a field of view of the first imaging device such that the first imaging device captures the image of the plurality of mirrors, the plurality of mirrors each directly reflecting the first eye.
4 more elements
A method comprising:
- capturing, with a first imaging device, an image of a plurality of mirrors coupled to a frame of a device, the plurality of mirrors reflecting a first eye of a user of the device, wherein the plurality of mirrors are disposed within a field of view of the first imaging device such that the first imaging device captures images of the plurality of mirrors, the plurality of mirrors each directly reflecting the first eye;
- adjusting, with a mirror angle adjustment device, an angle of at least one mirror of the plurality of mirrors relative to the first eye of the user to align the at least one mirror of the plurality of mirrors to reflect the first eye to the first imaging device;
- and
- tracking, based at least in part on the image of the plurality of mirrors reflecting the first eye, a gaze direction of the user.
