Abstract

A system includes a display and a camera module configured to capture forward real video and to output the forward real video on the display. A light source may be configured to generate light, and a navigation module may receive instructions regarding locating a target destination and may cause the light to be focused into a beam directed at the target destination as the user views both the forward real video and beam on the display. When the user reaches the desired location or orientation, the target destination is visibly illuminated by the beam of light.

First claim

What is claimed is:

1. An apparatus comprising:
a display;
a camera configured to capture and output forward real video onto the display;
a light source configured to generate light; and
a circuitry configured to:
receive instructions regarding locating a target destination; and
cause the light to be focused into a beam directed towards the target destination as the user views the forward real video and the beam light on the display;

wherein the beam changes color based on a proximity to the target destination.

2. The apparatus of claim 1 , wherein the circuitry locates the target destination based at least in part on a relative position of an object captured in the forward read video.

3. The apparatus of claim 1 , wherein the target destination is visibly illuminated by the beam of light.

4. The apparatus of claim 1 , wherein the light source includes a beam concentrator configured to concentrate emitted light.

5. The apparatus of claim 3 , wherein a beam concentrator is attached to a camera flash module.

6. The apparatus of claim 1 , wherein the circuitry is further configured to visually acquire the target destination using at least one of: image recognition, gyro, a speed sensor, or satellite-based radio-navigation system data.

7. The apparatus of claim 1 , further comprising a satellite-based radio-navigation system receiver that receives current position information from a satellite-based radio-navigation system receiver.

8. The apparatus of claim 1 , wherein the beam flashes.

9. The apparatus of claim 1 , further comprising a speaker configured to audibly alert a user based on a position of the user.

10. The apparatus of claim 1 , further comprising a vibrating module configured to vibrate to alert a user based on a position of the user.

11. A non-transitory computer-readable medium comprising instructions that, in response to execution of the instructions by one or more processors, cause the one or more processors to perform the following operations:
receive satellite-based radio-navigation system data;
receive forward real video from a camera;
cause a beam directional component to direct a beam of light towards a target destination based on the satellite-based radio-navigation system data; and
initiate a display of the forward real video on a handheld display and the beam of light as the user views the handheld display;
wherein the one or more processors are further configured to cause the beam of light to be directed in a direction towards the target destination within the handheld display to urge the user to move the handheld display in the direction until the target destination is visible within the handheld display.

12. The non-transitory computer-readable medium of claim 11 , wherein the one or more processors are further configured to cause a speaker to audibly alert a user based on a position of the user.

13. The non-transitory computer-readable medium of claim 11 , wherein the one or more processors are further configured to locate the target destination based at least in part on a relative position of an object captured in the forward read video.
