Abstract
Abstract An automatic self-administered interrogating apparatus that projects a series of film-frame-recorded images onto a rear projection screen. At least many of such images simultaneously present to the viewer both a question and a list of multiple choice answers, any or all of which answers may be selected by actuation of respective response buttons before a new question-answer image is brought into view on the screen. Each question has a serial number that is recorded together with the several answers, and each answer is coded on the basis of branching logic to control the number of film frames to be advanced for presentation of the next question-answer image. A selection device is included for determining which of the several film advancement codes is honored when the choice of answers necessitates such selection.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
125 words
An automatic self-administered interrogating apparatus comprising, film strip means for visually presenting a series of image frames at a viewing station, at least many of said image frames containing multiple answers viewable simultaneously at such station, and each such frame having an identification code affiliated with it, together with frame-count-advance codes respective to said answers, answer selection means operable to indicate choice of any one, several, or all of the aforesaid answers, recording means for storing said identification code and answer-choice information from said answer selection means, frame-count-advance selection means essentially comprising a bit-polarity-dominant logic circuitry for selecting frame-count-movement information from among the codes of the chosen answers, and means for effecting advancing movement of said film strip means according to such frame-count-movement information selection.
Claim 2
Dependent Claim
125 words
