Abstract

A portable eye tracker device is disclosed which includes a frame, at least one optics holding member, a movement sensor, and a control unit. The frame may be a frame adapted for wearing by a user. The at least one optics holding member may include at least one illuminator configured to selectively illuminate at least a portion of at least one eye of the user, and at least one image sensor configured to capture image data representing images of at least a portion of at least one eye of the user. The movement sensor may be configured to detect movement of the frame. The control unit may be configured to control the at least one illuminator for the selective illumination of at least a portion of at least one eye of the user, receive the image data from the image sensors, and receive information from the movement sensor.

Claims20

Dependent claims

A method for calibrating a gaze detection system, wherein the method comprises:

displaying a plurality of multipurpose virtual objects as part of an interactive virtual experience in a virtual reality environment on a display of a wearable device worn by a user;
selecting a multipurpose virtual object of the plurality of multipurpose virtual objects based at least in part on a determination that the user is anticipated to interact with the multipurpose virtual object during the interactive virtual experience;
detecting a user interaction of the user with the multipurpose virtual object during the interactive virtual experience;
determining that the user interaction of the user with the multipurpose virtual object causes a change to the multipurpose virtual object;
and
responsive to determining that the user interaction of the user with the multipurpose virtual object causes the change to the multipurpose virtual object, initiating, during the interactive virtual experience, a calibration process of the gaze detection system, the calibration process comprising:
determining a gaze direction of the user relative to the multipurpose virtual object with the gaze detection system of the wearable device;
and
calibrating the gaze detection system based at least in part on the gaze direction.

6 more elements

A non-transitory machine-readable medium having instructions stored thereon for calibrating a gaze detection system, wherein the instructions are executable by at least one processor to at least:

displaying a plurality of multipurpose virtual objects as part of an interactive virtual experience in a virtual reality environment on a display of a wearable device worn by a user;
selecting a multipurpose virtual object of the plurality of multipurpose virtual objects based at least in part on a determination that the user is anticipated to interact with the multipurpose virtual object during the interactive virtual experience;
detect a user interaction of the user with the multipurpose virtual object during the interactive virtual experience;
determine that the user interaction of the user with the multipurpose virtual object causes a change to the multipurpose virtual object;
and
responsive to determining that the user interaction of the user with the multipurpose virtual object causes the change to the multipurpose virtual object, initiate, during the interactive virtual experience, a calibration process of the gaze detection system, the calibration process comprising:
determine a gaze direction of the user relative to the multipurpose virtual object with the gaze detection system of the wearable device;
and
calibrate the gaze detection system based at least in part on the gaze direction.
