Abstract

A method of adjusting an image projected by a projector in operative communication with a smartphone having a touch screen display, wherein the method includes projecting an image onto an adjacent surface using the projector and generating an image adjustment user interface on the touch screen display. The image adjustment user interface defines an image adjustment field on the touch screen display. The method further includes detecting a single finger gesture made by a user within the image adjustment field on the touch screen display and generating an image adjustment signal corresponding to the detected signal finger gesture. The projected image is then adjusted in accordance with the image adjustment signal.

Claims

1. A set of computer executable instructions capable of being downloaded onto a smartphone having a touch screen display and a projector in operative communication with the smartphone, the set of computer executable instructions being capable of configuring the smartphone to:

send a signal to the projector for projecting an image onto an adjacent surface;

generate an image adjustment user interface on the touch screen display, the image adjustment user interface defining an image adjustment field on the touch screen display;

detect a single finger gesture made by a user within the image adjustment field on the touch screen display;

generate an image adjustment signal corresponding to the detected signal finger gesture; and

adjust the projected image in accordance with the image adjustment signal.

2. The set of computer executable instructions recited in claim 1, wherein the projected image defines an image height and an image width, wherein the step of detecting the single finger gesture includes detecting one of:

a first finger gesture in a first axial direction to adjust image height; and

a second finger gesture in a second axial direction perpendicular to the first axial direction to adjust image width.

3. A method of adjusting an image projected by a projector in operative communication with a smartphone having a touch screen display, the method comprising the steps of:

projecting an image onto an adjacent surface using the projector;

generating an image adjustment user interface on the touch screen display, the image adjustment user interface defining an image adjustment field on the touch screen display;

detecting a single finger gesture made by a user within the image adjustment field on the touch screen display;

generating an image adjustment signal corresponding to the detected signal finger gesture; and

adjusting the projected image in accordance with the image adjustment signal.

4. The method recited in claim 3, wherein the projected image defines an image height and an image width, wherein the step of detecting the single finger gesture includes detecting one of:

a first finger gesture in a first axial direction to adjust image height; and

a second finger gesture in a second axial direction perpendicular to the first axial direction to adjust image width.

5. The method recited in claim 3, wherein the adjusting step includes adjusting the position of the projected image on the adjacent surface.

6. The method recited in claim 3, further comprising the step of focusing the projected image automatically independent of receiving user input.

7. The method recited in claim 3, further comprising the step of correcting image distortion automatically independent of receiving user input.

8. The method recited in claim 7, wherein the step of correcting image distortion includes making a keystone correction.

9. The method recited in claim 3, wherein the adjusting step includes adjusting the shape of the projected image.

10. An image adjustment system adapted for use with a smartphone having a touch screen display adapted to detect a single finger gesture made on the smartphone, the smartphone being in operative communication with a projector adapted to project an image onto an adjacent surface, the image adjustment system comprising:

a user interface module in operative communication with the touch screen display and adapted to generate an image adjustment user interface including an image adjustment field on the touch screen display;
