Many domestic appliances and much office equipment is controlled using
a keypad and a small digital display. Programming such devices is
problematical for the blind and visually handicapped. In this paper,
we describe a device that may be used to read the displays on these
devices. The device is designed to accept a description of the display
being read, which specifies the types and locations of elements of
the display. Images are captured using a handheld webcam. Images
are processed to remove the distortions due to the camera orientation.
The elements of the screen are interpreted and a suitable audio output
is generated. In suitably illuminated scenes, the display data is
interpreted correctly in approximately 90\% of the cases investigated.
