Methods for using wireless phones having optical capabilities
First Claim
1. A method of using a phone that includes a microphone, a 2D optical sensor, and a wireless interface, the wireless interface being capable of transmitting an RF signal conveying information corresponding to audio sensed by said microphone, the method comprising:
- sensing a pattern in first image data produced by the phone'"'"'s 2D sensor;
sensing said pattern in second image data subsequently produced by said 2D sensor; and
determining a movement parameter by reference to the sensed pattern in the first and second image data.

Abstract
A wireless phone is equipped with a 2D optical sensor, enabling a variety of applications. For example, such a phone may also be provided with a digital watermark decoder, permitting decoding of steganographic data on imaged objects. Movement of a phone may be inferred by sensing movement of an imaged pattern across the optical sensor'"'"'s field of view, allowing use of the phone as a gestural input device through which a user can signal instructions to a computer-based process. A variety of other arrangements by which electronic devices can interact with the physical world are also detailed, e.g., involving sensing and responding to digital watermarks, bar codes, RFIDs, etc.

7. A method of employing a cameraphone as a gestural user interface to a computer-based process, the phone including a microphone, a 2D optical sensor, and a wireless interface, the wireless interface being capable of transmitting an RF signal conveying information corresponding to audio sensed by said microphone, the method comprising:
-
positioning the phone so that the camerphone'"'"'s 2D sensor captures an image of a pattern; moving the phone so that said pattern moves within a field of view of said 2D sensor; and through said movement of the phone, signaling user instructions to a computer-based process. - View Dependent Claims (8, 9, 10, 11, 12)

- 15. A method of interacting with an automated system to produce a desired response, the method employing a physical article that conveys machine-readable data, the system including cell phone equipped with an imaging sensor useful in sensing said machine readable data, the method characterized in that a user must cause relative movement between the physical article and the sensor as part of said interaction, in order for said system to produce said desired response.
