Abstract
Interactive electronic polling/testing/didactic apparatus employs a microprocessor having fixed (ROM) and variable (RAM) memory connected thereto. A sequence of output visual messages are provided under microprocessor control. A user actuated input device, e.g., a keyboard, enters a user reaction to the visual material presented. The user responses are accumulated, and reported as via a digital printer. The response significance varies with application, and may represent for example, game results, preferences, opinion in a sampling or polling context, or educational achievement.
