Abstract
An interactive information retrieval system is disclosed in which a large number of user terminals interact bilaterally with a centralized computer controlled data base by using a communications controller. In order to speed up the response time of the system, long messages from the controller to the terminal are broken into two segments, one segment just sufficiently long to engage the attention of the user while the balance of the message is being transmitted and verified. The balance of the long message is contained in a second segment. This process and apparatus may be implemented by hard-wired circuitry or by a programmed computer.
