| 20080244468 | Gesture Recognition Interface System with Vertical Display - One embodiment of the invention includes a gesture recognition interface system. The system may comprise a substantially vertical surface configured to define a gesture recognition environment based on physical space in a foreground of the substantially vertical surface. The system may also comprise at least one light source positioned to provide illumination of the gesture recognition environment. The system also comprises at least two cameras configured to generate a plurality of image sets based on the illumination being reflected from an input object in the gesture recognition environment. The system further comprises a controller configured to determine a given input gesture based on changes in relative locations of the input object in each of the plurality of image sets. The controller may further be configured to initiate a device input associated with the given input gesture. | 10-02-2008 |
| 20090103780 | Hand-Gesture Recognition Method - One embodiment of the invention includes a method of providing device inputs. The method includes illuminating hand gestures performed via a bare hand of a user in a foreground of a background surface with at least one infrared (IR) light source. The method also includes generating a first plurality of silhouette images associated with the bare hand based on an IR light contrast between the bare hand and the background surface and generating a second plurality of silhouette images associated with the bare hand based on an IR light contrast between the bare hand and the background surface. The method also includes determining a plurality of three-dimensional features of the bare hand relative to the background surface based on a parallax separation of the bare hand in the first plurality of silhouette images relative to the second plurality of silhouette images. The method also includes determining a provided input gesture based on the plurality of three-dimensional features of the bare hand and comparing the provided input gesture with a plurality of predefined gesture inputs in a gesture library. The method further includes providing at least one device input corresponding to interaction with displayed visual content based on the provided input gesture corresponding to one of the plurality of predefined gesture inputs. | 04-23-2009 |
| 20090115721 | Gesture Recognition Light and Video Image Projector - A system and method is provided for a gesture recognition interface system. The system comprises a projector configured to project colorless light and visible images onto a background surface. The projection of the colorless light can be interleaved with the projection of the visible images. The system also comprises at least one camera configured to receive a plurality of images based on a reflected light contrast difference between the background surface and a sensorless input object during projection of the colorless light. The system further comprises a controller configured to determine a given input gesture based on changes in relative locations of the sensorless input object in the plurality of images, and being further configured to initiate a device input associated with the given input gesture. | 05-07-2009 |
| 20090234844 | Systems and Methods for Extracting Application Relevant Data from Messages - Systems and methods are provided for extracting application relevant data from messages. In one embodiment, a system can comprise a message parser that parses messages and builds a message tree having one or more objects, one or more data type templates that define a given data type based on one or more data elements and a comparison engine that matches data elements in the one or more objects with data elements in the one or more data type templates. The comparison engine groups data elements in the one or more objects that matches data elements in the one or more data templates as a specific data type corresponding to the associated data type template that is matched. | 09-17-2009 |
| 20100026723 | Image magnification system for computer interface - One embodiment of the invention includes a computer interface system. The system comprises a user interface screen configured to display visual content and an input system configured to detect a presence of an input object within a threshold distance along a normal axis of the user interface screen. The system further comprises a graphical controller configured to magnify a portion of the visual content that is located at an approximate location of a base of the normal axis on the user interface screen. | 02-04-2010 |
| 20100050133 | Compound Gesture Recognition - One embodiment of the invention includes a method for executing and interpreting gesture inputs in a gesture recognition interface system. The method includes detecting and translating a first sub-gesture into a first device input that defines a given reference associated with a portion of displayed visual content. The method also includes detecting and translating a second sub-gesture into a second device input that defines an execution command for the portion of the displayed visual content to which the given reference refers. | 02-25-2010 |
