Abstract
A retinal display projection device comprising a micro-projection component (2) arranged for projecting an image directly onto the retina of a user wearing the device, characterized in that said micro-projection component is arranged for projecting an image outside of the normal field of view of said user.
Claims21
A retinal display apparatus comprising:
- a head-mounted user equipment;
- a projection device (2, 3) mounted on the head-mounted user equipment with all of the projection device being outside a normal, forward field of view of a user, such that no part of the device is in the normal, forward field of view of the user, the projection device comprising
- a micro-projection component (2) mounted on the head-mounted user equipment, the micro-projection component being a non see-through device and being outside a normal, forward field of view of the user;
- wherein the micro-projection component is arranged for projecting an image directly onto the retina (62) of the user, characterized in that said micro-projection component (2) is arranged for projecting an image directly onto the retina from a position outside of the normal field of view of said user, such that the user has to change gazing direction from a horizontal, forward gaze by at least 15 degrees in order to have the image reach the user's retina so the user can view the projected image.

A retinal display projection device (2, 3) comprising:
- a micro-projection component (2) arranged for mounting on glasses for projecting an image directly onto the retina (62) of a user wearing the device, the micro-projection component being a non see-through device with all of the projection component being outside a normal, forward field of view of a user, such that no part of the device is in the normal, forward field of view of the user, the projection device comprising;
- said micro-projection component (2) being positioned for projecting an image directly onto the retina from a position outside of the normal field of view of said user, such that the user has to change gazing direction from a horizontal, forward gaze by at least 15 degrees in order to have the image reach the user's retina so the user can view the projected image;
- wherein one of an angle and a position of the micro-projection component is adjustable by the user;
- a control component (3) arranged for being mounted outside the field of view of said user when said glasses are worn, said micro-projection component (2) and said control component (3) being communicatively coupled;
- and
- a remote control (5) communicatively coupled to the control component.

A projection device for mounting on a head-mounted user equipment comprising:
- a non see-through micro-projection component;
- mounting means for mounting the micro-projection component on the head-mounted user equipment outside a normal, forward field of view of a user, such that no part of the device is in the normal, forward field of view of the user;
- wherein the micro-projection component is arranged for projecting an image directly onto the retina of the user;
- wherein the micro-projection component is arranged for projecting an image directly onto the retina from a position outside of the normal field of view of said user, such that the user has to change gazing direction from a horizontal, forward gaze by at least 15 degrees in order to have the image reach the user's retina so the user can view the projected image.
