摘要： A system and method for tracking a laser spot on a projected computer screen image computes a projective transformation matrix using the projected computer screen image electronically captured in a frame of image data. The projective transformation matrix is computed by fitting a polygon to a contour of each graphical object in the frame of image data and determining whether the polygon for each graphical object satisfies a set of predefined parameters to find a candidate polygon that corresponds to an outline of the projected computer screen image in the frame of image data.

摘要： A resource accessibility engine according to the present invention uses a resource-specific knowledge base and user preferences to convert a resource into an improved accessibility resource. Examples of a resource include a website, document, webpage image file, multimedia file, auditory file or any other text and/or non-text record. The resource-specific knowledge includes content and formatting information that reduces ambiguities, translates implied information into explicit information and improves the accessibility of the resource content. The user preferences represent the physical capabilities of the user's access device, and the user's semantic and personal preferences for how content should be displayed. An editor uses an annotation wizard to create the resource-specific knowledge base based on the original resource.

摘要： Embodiments disclosed herein include methods and apparatuses for providing security to computer users with disabilities, who configure their computers to personalize output in a fashion that enables the user to more easily understand the content of the output. While previously a computer configured to personalize output accordingly may have served as a source of disability information to unauthorized parties accessing the computers, embodiments disclosed herein configure computers for personalization without leaving thereon a record how the personalization was specified during the configuration process. Thus, an unauthorized party gaining access to the user's computer would find it very difficult, if not impossible, to determine the user's disability from an inspection of the computer, so the user is much less likely to become a victim of fraud based on an unauthorized discovery of information regarding vulnerabilities.

摘要： A source content enhancement system is described. A method for disambiguation of content and localization of culturally sensitive content including parsing content of an object for cultural objects and components, gathering knowledge about the object, inferring knowledge about the object, checking if the object is culturally appropriate, checking if the object and section of an object conform to local standards, and creating an adapted rendering of the object.
