Abstract

The invention described herein represents a significant improvement for the presentation of visual information when using handheld devices. In on embodiment, a handheld device such as a cell phone is modified to include a means for projecting an image onto a remote surface such as a remote surface (wall). Also integrated are a means to sense when the cell phone moves relative to the image on the remote surface (wall) and to offset said relative movement through a means for stabilizing the image. This invention thus enables the user of the cell phone to produce and interact with a large visual media display while the size of the cell phone is not significantly increased. Many handheld devices will be improved by incorporating the means to project a large stable image disclosed herein.

Claims

1. A handheld means for displaying an image,

wherein a means for projecting an image onto a remote surface is provided,

wherein a means for detecting movement of said handheld device is provided,

wherein a means for offsetting said movement and thereby stabilizing said image is provided.

2. The invention of claim 1 wherein said handheld means includes the means to connect to a remote computer.

3. The invention of claim 1 wherein said handheld means is designed to produce an image in response to software instructions.

4. A process for producing an image from a handheld device,

wherein said image is projected from said handheld device onto a remote surface,

wherein movement of said handheld device relative to said remote surface is sensed,

wherein adjustments within said handheld device are made to offset said movement.

5. The invention of claim 4 wherein said handheld device includes the means to connect to a remote computer.

6. The invention of claim 4 wherein said handheld device is designed to produce an image in response to software instructions.
