Latest Patents
One of his latest patents is titled "Method for establishing fixation employing speech recognition." This invention provides a method for establishing fixation during computerized visual field perimetry. It requires the subject to verbally identify the symbol employed as fixation targets as they appear. Speech recognition techniques are utilized to evaluate the subject's response, and upon correctly identifying the fixation symbol, a visual test stimulus is displayed at a predetermined location within the subject's field of vision. The fixation symbols can include geometrical shapes, letters, numbers, pictures, or other easily identifiable symbols.
Another significant patent by Weiss is the "Method and apparatus for measuring contrast sensitivity." This novel contrast sensitivity test employs an adaptive contrast threshold algorithm. It is designed as a two-alternative forced choice examination using grating stimuli of randomly interleaved spatial frequencies. The orientation of the stimulus is either tilted to the left or right of vertical. During the examination, a series of grating stimuli is presented to the subject, who is asked to indicate the orientation of each stimulus. The contrast level for the next stimulus is adjusted based on the subject's previous responses, allowing for a more accurate assessment of contrast sensitivity.
