Abstract

A tactile display system is described which may be constructed into a compact hand-held unit, similar to a computer light pen or flashlight, with a number of photocells or light sensors in one end and a small tactile display conveniently located on the side of the probe. This would be located so that the finger of the blind person would rest upon it. The unit may be either self-contained with its own power source, or it may be connected to a cable from a larger power supply and/or embossing mechanism to make a more permanent record of the sense display.

Tactile Display System

A tactile display system is described which may be constructed into a compact hand-held unit, similar to a computer light pen or flashlight, with a number of photocells or light sensors in one end and a small tactile display conveniently located on the side of the probe. This would be located so that the finger of the blind person would rest upon it. The unit may be either self- contained with its own power source, or it may be connected to a cable from a larger power supply and/or embossing mechanism to make a more permanent record of the sense display.

The system as shown in Fig. A consists of the following components:

1) A shroud or series of shrouds 1 that may be mounted on the calculator 3 to facilitate locating the probe over a specific readout position, helping to restrict the incidental light. The top of shroud 1 may contain a tactile position indicator 5 as well as a locating notch 7. Shroud 1 may also act as a physical adaptor from various calculators to a standard probe.

2) A removahle or replaceable adapter section 9 which allows for the various shapes and sizes of the lighted display. Fiber optics 11 are used to guide the light to the appropriate photocells 13 located in the decode unit 15.

3) The decode unit 15 contains the photocell sensors 13, decoder 17, tactile display 19, controls and drivers 21. Decode unit 15 may also contain a power supply 23 if so equipped.

4) The decode unit 15 may be cable connected to recorder 25 to provide a paper embossed record of the display. One feature of the recorder unit 25 would be that it be equipped with a manual keyboard, which offers the user the opportu...
