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.
Claims10
In combination, a microprocessor;
- a read only memory, a variable content memory, an address bus, and a data bus connected to said microprocessor;
- visual image forming means including means for displaying a sequence of images, and display control means for advancing the image then formed by said image forming means;
- said image forming means comprising a slide projector containing plural projectable slides, and wherein said display control means comprises a projector-controlling switch to advance the slide then being projected by said slide projector;
- means controlled by said microprocessor for selectively actuating said display control means;
- data input means, and interface means connected to said address bus and said data bus for selectively connecting said data input means to said data bus;
- said variable content memory including plural answer data storage means in one-to-one correspondence with at least a subset of said images;
- and means for loading said answer data storage means employing said data input means.
