Abstract
Systems and methods for direct projection of images onto an eye retina including, for example, systems and methods for directing a projection/imaging optical path so as to track a location of the eye in accordance with a gaze direction thereof. This enables for projecting images onto specific/fixed locations on the eye retina, while the gaze direction changes.
Claims21
An eye projection system, comprising:
- an image projection system adapted to obtain image data and produce an image projection comprising a plurality of light beam portions corresponding to pixels of said image data;
- an eye projection optical module adapted to direct the plurality of light beam portions of said image projection towards an eye of a user;
- and
- a gaze tracking controller configured and operable for controlling the operation of at least one of the image projection system or the eye projection optical module in accordance with data indicative of a gaze direction of the eye, so as to direct the plurality of light beam portions of the projected image onto a retina of the eye in accordance with a line of sight of the eye at different gaze directions to thereby compensate for changes in the gaze direction, while not compensating for changes in the line of sight that are associated with at least one of saccadic or tremor eye movements of the eye, thereby providing that the projected image on the retina, in any specific gaze direction, appears stable and fixed to extent permitted by saccadic eye movement.

An eye projection method, comprising:
- obtaining image data and producing an image projection comprising a plurality of light beam portions corresponding to pixels of said image data;
- and
- directing the plurality of light beam portions of said image projection towards an eye of a user;
- wherein said directing comprises compensating for changes in the gaze direction to direct the plurality of light beam portions of the projected image onto a retina of the eye in accordance with a line of sight of the eye at different gaze directions;
- and
- wherein said compensating for changes in the gaze direction does not include compensations for changes in the line of sight of the eye that are associated with at least one of saccadic and tremor eye movements of the eye, thereby providing that the projected image on the retina, in any specific gaze direction, appears stable and fixed to extent permitted by saccadic or tremor eye movement.
3 more elements
An eye projection system, comprising:
- an image projection system adapted to obtain image data and produce an image projection comprising a plurality of light beam portions corresponding to pixels of said image data, such that each light beam portion of said plurality of light beam portions being projected with respective projection angle αscn={αxscn , αyscn}=S({Px,Py} corresponding to a two dimensional location {Px,Py} of its corresponding pixel in said image data, where S is an image scan function;
- an eye projection optical module adapted to direct the light beam portions of said image projection towards an eye of a user, the eye projection optical module comprising an angular beam relay module and a gaze tracking deflector comprising an addressable optical deflecting unit;
- and
- a gaze tracking controller is configured and operable for controlling the operation of at least one of the image projection system and the eye projection optical module in accordance with data indicative of a gaze direction of the eye, so as to direct the light beam portions of the projected image onto a retina of the eye in accordance with a line of sight of the eye at different gaze directions to thereby compensate for changes in the gaze direction;
- wherein said gaze tracking controller is configured and operable not to compensate for changes in the line of sight that are associated with at least one of saccadic and tremor eye movements of the eye.
