Flexible Interaction-Based Computer Interfacing Using Visible Artifacts

US Patent:
2006007, Apr 6, 2006
Filed:
Oct 1, 2004
Appl. No.:
10/957123
Inventors:
Frederik Moesgaard Kjeldsen - Poughkeepsie NY, US
Anthony Levas - Yorktown Heights NY, US
Gopal Pingali - Mohegan Lake NY, US
Assignee:
International Business Machines Corporation - Armonk NY
International Classification:
H04N 7/18
US Classification:
348137000
Abstract:
An exemplary technique for interaction-based computer interfacing comprises determining if an interaction with a visible artifact is a recognized interaction. When the interaction is a recognized interaction, control information is determined that has one of a plurality of types. The control information is determined by using at least the visual artifact and characteristics of the recognized interaction. The control information is mapped to one or more tasks in an application, such that any task that requires control information of a specific type can get the control information from any visual artifact that creates control information of the specific type. The control information is suitable for use by the one or more tasks.

Computer System Providing Hands Free User Input Via Optical Means For Navigation Or Zooming

US Patent:
6864912, Mar 8, 2005
Filed:
Dec 16, 1999
Appl. No.:
09/464841
Inventors:
Robert B. Mahaffey - Austin TX, US
Lawrence F. Weiss - Round Rock TX, US
Richard S. Schwerdtfeger - Round Rock TX, US
Frederik C. Kjeldsen - Poughkeepsie NY, US
Assignee:
International Business Machines Corp. - Armonk NY
International Classification:
H04N007/18
US Classification:
348 61, 348 63, 348 1401
Abstract:
A system and method are described for selectively providing display data to a display device dependent upon an optically detected proximity of a user's face to a camera. One embodiment of a computer system includes the camera, the display device, and a processing system. The camera produces image signals representing a first image and a second image of the user's face, wherein the first image precedes the second image in time. The processing system receives the image signals and analyzes the first and second images to determine the proximity of the user's face to the camera. More specifically, the processing system compares the first and second images to determine the proximity of the user's face to the camera in the second image relative to the proximity of the user's face in the first image. The processing system provides the display data to the display device dependent upon the proximity of the user's face to the camera. In order to determine the proximity of the user's face to the camera, the processing system may compare: (i) a size of the user's face in the first and second images, and/or (ii) a distance between selected facial features of the user in the first and second images.
