Terminal with projected display
View Patent ↗A mobile data and/or communication terminal is provided which includes an optical system for the generation of a projected display as well as parts for stabilizing the display when the terminal is moved.
1. A projection apparatus comprising:
an optical system for generating a projected display, the projected display including a symbol;
a light beam source for creating a highlighted position in the projected display;
a camera for capturing at least a portion of the projected display including the highlighted position, wherein the projection apparatus activates the symbol when the highlighted position is moved to the symbol in the projected display thereby acting as an operator input for the projection apparatus; and
a sensor that detects physical movement of the projection apparatus;
wherein the projection apparatus determines a position of the projection apparatus resulting from the physical movement and compensates the optical system to stabilize a displacement of the projected display based on the determined position.
2. The projection apparatus of claim 1 , wherein the symbol includes a keyboard symbol.
3. The projection apparatus of claim 1 , including an integrated keyboard.
4. The projection apparatus of claim 1 , wherein the light beam source includes a laser pointer.
5. The projection apparatus of claim 1 , wherein compensation of the optical system to stabilize the displacement of the projected display is activated via a switch on the projection apparatus.
6. The projection apparatus of claim 1 , wherein the projection apparatus is at least one of a mobile data terminal, a communication terminal, a video telephone and a video camera.
7. A method of receiving an operator input at a projection apparatus, the method comprising:
generating a projected display through an optical system of the projection apparatus, the projected display including a symbol;
projecting a light beam source on to the projected display to create a highlighted position in the projected display;
detecting physical movement of the projection apparatus;
determining a position of the projection apparatus resulting from the physical movement and compensating the optical system to stabilize a displacement of the projected display based on the determined position;
capturing at least a portion of the projected display with a camera, the portion including the highlighted position; and
activating the symbol when the highlighted position is moved to the symbol in the projected display.
8. The method of claim 7 , wherein the symbol includes a keyboard symbol.
9. The method of claim 7 , wherein the light beam source includes a laser pointer.
10. The method of claim 7 , including activating compensation of the optical system via a switch on the projection apparatus.
11. The method of claim 7 , wherein the projection apparatus is at least one of a mobile data terminal, a communication terminal, a video telephone and a video camera.
12. A projection apparatus comprising:
an optical system for generating a projected display;
a light beam source for creating a highlighted position in the projected display;
a camera for capturing at least a portion of the projected display including the highlighted position, wherein the projection apparatus activates an operator input when the highlighted position is moved in the projected display; and
a sensor that detects physical movement of the projection apparatus;
wherein the projection apparatus determines a position of the projection apparatus resulting from the physical movement and compensates the optical system to stabilize a displacement of the projected display based on the determined position.
13. The projection apparatus of claim 12 , wherein the projected display includes a keyboard symbol.
14. The projection apparatus of claim 12 , including an integrated keyboard.
15. The projection apparatus of claim 12 , wherein the light beam source includes a laser pointer.
16. The projection apparatus of claim 12 , wherein compensation of the optical system to stabilize the displacement of the projected display is activated via a switch on the projection apparatus.
17. The projection apparatus of claim 12 , wherein the projection apparatus is at least one of a mobile data terminal, a communication terminal, a video telephone and a video camera.
18. The projection apparatus of claim 12 , wherein the projection apparatus activates a symbol when the highlighted position is moved to the symbol in the projected display.
19. A method of receiving an operator input at a projection apparatus, the method comprising:
generating a projected display through an optical system of the projection apparatus;
projecting a light beam source on to the projected display to create a highlighted position in the projected display;
detecting physical movement of the projection apparatus;
determining a position of the projection apparatus resulting from the physical movement and compensating the optical system to stabilize a displacement of the projected display based on the determined position;
capturing at least a portion of the projected display with a camera, the portion including the highlighted position; and
activating an operator input when the highlighted position is moved in the projected display.
20. The method of claim 19 , wherein the projected display includes a keyboard symbol.
21. The method of claim 19 , wherein the light beam source includes a laser pointer.
22. The method of claim 19 , including activating compensation of the optical system via a switch on the projection apparatus.
23. The method of claim 19 , wherein the projection apparatus is at least one of a mobile data terminal, a communication terminal, a video telephone and a video camera.
24. The method of claim 19 , wherein the projection apparatus activates a symbol when the highlighted position is moved to the symbol in the projected display.
