The majority of visually impaired blind and deafblind people retain some degree of residual vision. Software called Dynamic Pattern System (DPS) was developed to utilize this residual vision by generating a range of different patterns, colors and shapes unique to each individual’s residual vision – called a pattern set. This pattern set can then be mapped to printable alphanumeric characters. Limited trials with the visually impaired suggested DPS may have value. This paper is a more detailed evaluation of DPS undertaken by a normally sighted person using low vision simulators that mimic different visual handicap conditions.
