Abstract

Portable electronic communication equipment, e.g., a mobile phone, includes a projector that is integrated into the mobile phone to project images, a camera senses views, including a view of projected images and of changes made to the projected image, e.g., by inserting an object, such as a finger, stylus, etc., into the projected image. The character of the changes, e.g., where a change occurs in an image, can be used as an input to the mobile phone. A method of using a portable communication device includes transmitting and receiving communications via a radio, projecting an image onto a surface, using a camera of the portable communication device to sense views including a view of a projected image by the projector, and detecting a change in the sensed view of the projected image to provide an input to the portable communication device.
