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)

13. A method comprising:
-
presenting an object to an imaging system, the object having formed thereon a pattern that steganographically encodes a plural symbol payload;
processing image data produced by said imaging system to determine an orientation of the object as viewed by the imaging system;
triggering a response to said object that depends, at least in part, on said orientation. - View Dependent Claims (14, 15, 16, 17)

18. A method comprising:
-
moving a wireless 2D imaging device that is physically coupled to a user'"'"'s body;
during said movement, using said device to capture plural frames of image data of a subject; and
processing said captured image data to characterize a movement parameter associated with said subject. - View Dependent Claims (19)

20. A method comprising:
-
providing a gaming table;
positioning on said table an article selected from the list consisting of;
a playing card or a gaming chip, said article being marked with a digital watermark indicia conveying a plural bit payload;
capturing image data corresponding to said article, using an image sensor proximate to the table;
decoding the plural bit payload from said captured image data; and
using said decoded payload to help deter gaming fraud.
