Abstract
An interactive computer terminal which is capable of complete hand-held operation with total freedom of position and location is provided. The terminal incorporates a self-contained full 75-character keyboard, a 20-character alpha numeric readout, and a 100-character memory. In order to assure review of any message, a conveniently positioned scroll switch is incorporated to advance or roll back any message in the memory for presentation on the display. The unique, totally portable hand-held interactive terminal is provided with a 20-key pad which is operated with one hand, while the other hand selects one of four different information levels for each key. Consequently, each of the 20 keys is capable of transmitting four different characters or other information, thereby assuring easy, compact transmission of all numeric, alphabetic, and punctuation characters with sufficient keyboard room available for command capability.
