Today, a new patent from Microsoft titled ‘Gaze detection in a see-through, near-eye, mixed reality display’ was published. It describes technology for gaze determination within a see-through, near-eye mixed reality display device. In some embodiments, a gaze determination coordinate system based on predetermined positioning of at least one light sensor and illuminators on the display device provides a three dimensional (3D) spatial relationship between the display device and each respective eye. A gaze vector for each eye may be determined based on the 3D spatial relationship. Based on gaze vectors for both eyes, a point of gaze may be determined which indicates one or more objects, real or virtual, at which a user is gazing, or more commonly stated as, at which the user is looking.
The technology provides various embodiments for gaze determination within a see-through, near-eye, mixed reality display device. In some embodiments, the boundaries of a gaze detection coordinate system can be determined from a spatial relationship between a user eye and gaze detection elements such as illuminators and at least one light sensor positioned on a support structure such as an eyeglasses frame. The gaze detection coordinate system allows for determination of a gaze vector from each eye based on data representing glints on the user eye, or a combination of image and glint data. A point of gaze may be determined in a three-dimensional user field of view including real and virtual objects. The spatial relationship between the gaze detection elements and the eye may be checked and may trigger a re-calibration of training data sets if the boundaries of the gaze detection coordinate system have changed.
Microsoft has been working on their own virtual reality glasses for years now. They have not yet confirmed whether there are any plans to release it to market or they are just mere research projects.
