Character Display and Input Device

This device provides a means of continuously visually presenting information such as an alphanumeric sequence to a person, and permitting him to cause a particular character to be printed by an appropriately wired typewriter. The means of triggering the print command can be a microswitch or any other sensor that can be operated at will by the user, when the desired character appears on the display.

The display 2 can be made of light-emitting diodes or liquid-crystal material, generally similar to a ticker tape display in a brokerage office. The number of characters that are simultaneously displayed can be either fixed or varied up to the capacity of the display. Appropriate information relating to the use of the typewriter 5, such as shift and line feed commands, are part of the character stream. The character stream itself consists of characters in the user's language arranged at random, with preferably the frequency of use distribution characteristic of that language. In use, the switch 4 is activated when the desired character appears in reference location 1 on display 2. The display and print information is generated by an integrated circuit and read-only memory chip 3. The display 2 could also be an oral one for use by blind persons. In this case, a digital to voice converter unit is needed.

The display can be remotely positioned from the typewriter. It can be mounted in a headset or table unit as the need may arise.
