Abstract

A system is provided for display of information. The system includes an audio device, a transparent display, and a mobile device in communication with the audio device and the transparent display. The mobile device projects information to the transparent display, and decreases projection of the information to the transparent display in response to a detection of an unsafe condition.

Claims

1. A system for display of information, comprising:

an audio device;

a transparent display; and

a mobile device in communication with the audio device and the transparent display, wherein the mobile device is configured to project information to the transparent display, to decrease projection of the information to the transparent display in response to a detection of an unsafe condition, and to increase the projection of the information to the transparent display in response to a determination that the unsafe condition has been resolved.

2. The system of claim 1, wherein the transparent display comprises a user wearable lens and a projector to project images on the lens.

3. The system of claim 1, wherein the unsafe condition comprises a user of the mobile device running, moving on stairs, or falling, and wherein the mobile device comprises a motion detector to detect the unsafe condition based on determining that the user of the mobile device is running, moving on stairs, or falling.

4. The system of claim 3, wherein the mobile device is further configured to send an alert message to a supervisor in response to determining that the user of the mobile device is falling.

5. The system of claim 1, wherein the mobile device is further configured to determine the location of the mobile device.

6. The system of claim 5, wherein determining the location of the mobile device comprises determining the location of the mobile device relative to at least one of an item with an electronic tag and a geographically fixed electronic tag using at least one of a radio frequency identification technology, a global positioning system technology, a forward link triangulation technology, a hybrid technology, and a motion detector technology.

7. The system of claim 5, wherein the unsafe condition comprises a user of the mobile device working near a dangerous machine or a dangerous area, and wherein detection of the unsafe condition is based on determining the location of the mobile device in relation to the dangerous machine or the dangerous area.

8. The system of claim 1, wherein the mobile device is further configured to promote speech recognition.

9. The system of claim 1, wherein detecting the unsafe condition is based on the user identifying the unsafe condition.

10. The system of claim 1, wherein the mobile device is further configured to convert the information to an audio signal.

11. The system of claim 1, further comprising a camera in communication with the mobile device, wherein the camera is configured to capture an image and send the image to the mobile device, wherein the mobile device is further configured to transmit the image.

12. The system of claim 11 wherein the mobile device is further configured to promote gesture recognition for gestures captured by the camera.

13. The system of claim 1, further comprising a light meter, wherein the unsafe condition is based on the light meter detecting an amount of light below a darkness threshold.

14. The system of claim 1, further comprising a digital compass to determine an orientation of the mobile device.

15. The system of claim 1, further comprising a server in communication with the mobile device, wherein the server is configured to access a database for the information.

16. A method for display of information, comprising:

projecting information to a transparent display via a mobile device;

decreasing, by the mobile device, projection of the information to transparent display in response to a detection of an unsafe condition; and

increasing, by the mobile device, the projection of the information to the transparent display in response to a determination that the unsafe condition has been resolved.

17. The method of claim 16, further comprising receiving a request for the information via at least one of a microphone, a pointer, a touch screen, a keyboard, and a camera.

18. A method for display of information, comprising:

projecting information to a transparent display via a mobile device; and

dimming, by the mobile device, the display intensity of the transparent display in response to a detection of an unsafe condition.

19. The method of claim 18, wherein the mobile device comprises an audio device to detect a level of noise above a noise threshold, wherein the mobile device is configured to increase the display intensity of the transparent display in response to detecting the level of noise above the noise threshold.

20. The method of claim 18, further comprising increasing, by the mobile device, the display intensity of the transparent display in response to a determination that the unsafe condition has been resolved.
