Abstract
A personal object such as a ring or wristwatch includes an integrated femtoprojector that operates as a mini viewer. The object includes an object body (such as a ring body or watch head) that may be wearable. A display is inset in the object body and is viewable through a window from a position external to the object body. Projection optics may be inset in the object body in an optical path between the display and the window. The projection optics are structured to magnify images produced by the display such that projected images are focused on a retina of a person when viewed from a viewing distance within a range of zero to two inches. A battery internal to the object body provides power to the display via a bus.
Claims20
A ring comprising:
- a ring body suitable for wearing on a finger;
- a display inset in the ring body;
- a window through which the display may be viewed from a position external to the ring body;
- projection optics inset in the ring body in an optical path between the display and the window, the projection optics structured to magnify images produced by the display such that projected images are focused on a retina of a person when viewed from a viewing distance within a range of zero to two inches, wherein the projection optics operate to produce the projected images to have a perceived image size that appear unclipped within an extent of a focal region of the retina and such that features of the projected images are resolvable by the retina when viewed from the viewing distance;
- and
- a battery internal to the ring body which provides power to the display via a bus.
A handheld personal object, comprising:
- an object body having a form factor suitable for holding in a human hand;
- a display inset in the object body;
- a window through which the display may be viewed from a position external to the object body;
- projection optics inset in the object body in an optical path between the display and the window, the projection optics structured to magnify images produced by the display such that projected images are focused on a retina of a person when viewed from a viewing distance within a range of zero to two inches, wherein the projection optics operate to produce the projected images to have a perceived image size that appear unclipped within an extent of a focal region of the retina and such that features of the projected images are resolvable by the retina when viewed from the viewing distance;
- and
- a battery internal to the object body which provides power to the display via a bus.
A wristwatch, comprising:
- a wrist band;
- a watch head including timekeeping elements;
- a display inset in the watch head;
- a window through which the display may be viewed from a position external to the watch head;
- projection optics inset in the watch head in an optical path between the display and the window, the projection optics structured to magnify images produced by the display such that projected images are focused on a retina of a person when viewed from a viewing distance within a range of zero to two inches, wherein the projection optics operate to produce the projected images to have a perceived image size that appear unclipped within an extent of a focal region of the retina and such that features of the projected images are resolvable by the retina when viewed from the viewing distance;
- and
- a battery internal to the watch head which provides power to the display via a bus.
