Audio-visual three-dimensional input/output
First Claim
1. A method of determining the location of an object in three-dimensional space, comprising:
- using an imaging device, capturing an image of a real world object;
determining a size of the real world object represented in the captured image; and
based on a size of the real world object and the size of the real world object represented in the captured image, determining three-dimensional coordinates of the real world object.

Abstract
Methods and apparatus for determining an object'"'"'s three-dimensional location (i.e. real world coordinates) using the audio-video infrastructure of a 3G cellular phone or a 3C (Computer, Communications, Consumer) electronic device. A first detection device (e.g. a camera) is used to capture images of the objects. The captured image data is used to compute location data of the object in a first two-dimensional plane. A second detection device (e.g. microphone or infrared detector) may be used to collect additional location data in a second plane, which when combined with image data from the captured images allows the determination of the real world coordinates (x, y, z) of the object. The real-world coordinate data may be used in various applications. If the size of an object of interest is known or can be calculated, and the size of the projected image does not vary due to rotation of the object, a single camera (e.g. the camera in a 3G or 3C mobile device) may be used to obtain three-dimensional coordinate data for the applications.
