The present invention discloses methods of archiving and optimizing lectures, presentations and other captured video for playback, particularly for blind and low vision individuals. A digital imaging device captures a preselected field of view that is subject to periodic change such as a whiteboard in a classroom. A sequence of frames is captured. Frames associated with additions or erasures to the whiteboard are identified. The Cartesian coordinates of the regions of these alterations within the frame are identified. When the presentation is played back, the regions that are altered are enlarged or masked to assist the low vision user. In another embodiment of the invention, the timing of the alterations segments the recorded audio into chapters so that the blind user can skip forward and backward to different sections of the presentation.

Segmenting and playback of whiteboard video capture

A screen reader software product for low-vision users, the software having a reader module collecting textual and non-textual display information generated by a web browser or word processor. Font styling, interface layout information and the like are communicated to the end user by sounds broadcast simultaneously rather than serially with the synthesized speech to improve the speed and efficiency in which information may be digested by the end user.

Whiteboard archiving and presentation method

A screen reader software product including a pattern store containing at least one user-definable array of keywords relating to a subject of interest and skim reading module adapted to apply the at least one array of keywords to a target document whereby only portions of the target document matching the at least one array of keywords are output by the screen reader software to an end user.

Reading alerts and skim-reading system

System-wide content-based text stylization by establishing an array of predefined stylization criteria, intercepting text output generated by an operating system to a graphics device driver, rasterizing the text according to the predefined stylization criteria and passing the rasterized images to the graphics device driver for display. The array of predefined stylization criteria includes criteria that modify font size, font type, font color, font highlighting, underline, bold, italics and invoke character replacement. Stylization may be based on parameters such as syllables, consonants, vowels, and punctuation and/or applied by a lookup table against predefined strings.
