Abstract: An apparatus for providing a magnetic visual display in which a magnetic field is exposed to a dispersion medium sealed between two surfaces and having distributed therein randomly-oriented magnetically-active flakes, thereby causing alignment of a portion of the flakes and allowing transmission of light through the dispersion medium in the region of the aligned flakes to form an image by the contrast between the areas of aligned and randomly-oriented flakes. The contrast may be enhanced by a light source on the opposite side of the device from the viewer. The image may be colored by coloring either of the surfaces, the dispersion medium, the flakes or the light from the light source.

Abstract: A personal learning system comprising a base structure with a base member for mounting a pair of training manuals and audio/visual apparatus having prerecorded instructional information for instructing a student in use of training manual course material.

Abstract: An electronic educational video system apparatus for connection to a standard television receiver for teaching basic skills to a child through the use of animated graphic displays which serve to motivate the child to utilize the apparatus and enhance the child's learning. A microprocessor cooperates with digital memory, a video generator, a sound generator, and a voice synthesizer to generate a display of a pictorial representation upon the television receiver combined with a request associated with the pictorial representation directing the child to provide a proposed correct response. The child's correct response is compared to the actual correct response stored in the digital memory so that the particular pictorial representation associated with a particular request may become animated to provide an indication to the child of the correctness of the child's response. The child may provide his or her response through a plurality of interchangeable input devices.

Abstract: An apparatus and method for providing a magnetic display in which a magnetic field produces visual patterns upon exposure to the apparatus. The apparatus comprises an enclosure which contains magnetically active flakes held within a dispersion medium which holds the magnetically active flakes in suspension, yet allows alignment of the flakes along the flux lines of the magnetic field when the flakes are exposed to the locus of the magnetic field.

Abstract: A presentation apparatus which can automatically adjust the total presentation time and presentation time intervals of a video material according to user's desired total presentation time so that the video material necessary for presentation can be screened within the desired total presentation time. The user inputs the desired total presentation time to the presentation apparatus. In the apparatus, the desired total presentation time is compared with a standard total presentation time to find a difference therebetween as an adjustment time. One of adjusting methods is selected on the basis of the found adjustment time. A data indicative of the selected adjusting method is stored in an adjustment memory.

Abstract: A support device for resolving questions provided with a question input unit for selective input of questions on information reproduced from an information reproducing unit. A question input unit is connected with a question extracting unit. If a question is input, the question extracting unit presents a plurality of prospective questions in the form of video information on a display unit and extracts a real question which coincides with questioner's question. The question extracting unit is connected with an answer unit, which automatically retrieves answer information on the extracted real question, and presents the answer information by video or audio information.

Abstract: The method of presenting events such as audio and video instructions to a computer user including the recording instructions in the form of an audio soudtrack 15 on a recording tape 10, assigning coded indicia 16 to the various instructional events of a computer program recorded in a memory 31 and recording the coded indicia and instructional events in a table lookup 29, recording a mulitplicity of each indicia on the recording tape adjacent the soundtrack portion the computer program event is to occur, and reading back the recording tape while feeding the audio signal to an audio output 36 and the indicia signal to the table lookup to cause the events or instructions to occur in synchronism.

Abstract: An interactive television system (10, 10a) for providing full motion synched compatible audio visual displays based on dynamic user selection (26) of a plurality of syllable synched compatible audio choices for a common full motion video frame presentation received over a common television channel. Two or more audio channels are synched to a common video channel, with the video being compatible will all audio channels. The interactive programming is transmitted via broadcast or cable TV and received (28) by VCR used as a tuner (12, 12a) or by a simplified TV head-end tuner (30), with the transmitted television signal having the audio channels either multiplexed into the video line or the existing audio channels. The received television signal is provided to a control module (14, 14a) which demultiplexes the signal (16, 16a) and ultimately combines the user selected audio signal with the video in an RF modulator (20) under computer control (18, 22, 24, 26) to provide the interactive display.

Abstract: An educational device is adapted to receive a programmed tape cassette having voice signals and data signals stored thereon. The programmed tape cassette is organized so that the voice signals include questions as well as other entertaining subject matter, while the data signals include answers to the corresponding questions. The voice signals and data signals are read from the tape cassette and a playback circuit provides a voice playback signal to a speaker, while providing a data playback signal to a microcomputer. The microcomputer is also connected to a keyboard and a display, as well as being connected to drive the tape cassette. In operation, the tape cassette is driven and an audio question is produced by the speaker. At the same time, the correct answer data is stored by the microcomputer. After the audio question has been generated, the tape cassette is stopped and a user is allowed to input answer data via the keyboard.
