Abstract
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.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
156 words
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.
Claim 2
Dependent Claim
156 words
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.
Claim 3
Dependent Claim
19 words
a combination as in claim 1 further comprising data output means connected to said address bus and data bus.
Claim 4
Dependent Claim
15 words
A combination as in claim 2 wherein said data output means comprises a digital printer.
Claim 5
Dependent Claim
26 words
A combination as in claim 1 further comprising an alphanumeric display, and interface means connecting said alphanumeric display with said data bus and said address bus.
Claim 6
Dependent Claim
23 words
A combination as in claim 1 further comprising audio/visual output means, and means responsive to said microprocessor for energizing said audio/visual output means.
Claim 7
Dependent Claim
57 words
A combination as in claim 1 wherein said date input means comprises a keyboard, wherein said microprocessor comprises means for comparing data entered at said keyboard with data stored in said answer data storage means, and wherein said variable content memory includes result storage means for storing the results of the comparisons effected by said comparing means.
Claim 8
Dependent Claim
41 words
A combination as in claim 1 wherein said data input means comprises a keyboard, and wherein said answer data storage loading means comprises switch means connected to said microprocessor for translating data from said keyboard to said answer data storage means.
Claim 9
Dependent Claim
146 words
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 at least one result storing means; and means for selectively loading said result storage means from said data input means.
Claim 10
Dependent Claim
146 words
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 at least one result storing means; and means for selectively loading said result storage means from said data input means.
Claim 11
Dependent Claim
19 words
