Abstract

A limited function, user interactive teaching apparatus includes a memory for storing a compilation of words and phrases to be used by the teaching apparatus and a pedagogical lesson database which includes a plurality of substantially identical, limited size, lesson frame data units, each such unit including a plurality of pointers for selecting words and/or phrases to be displayed during the execution of the program unit. Each program unit thus comprises, in the main, pointer data rather than substantive pedagogical data. A display is employed for displaying the selected words and phrases and, in addition, includes a movable indicator cursor or touch sensitive position indicator. A processor executes the pedagogical program, unit by unit. The processor fetches the selected words and/or phrases and provides them to the display in accordance with pointer data contained in each data unit. The apparatus is provided with x-y movement means for causing the cursor to move on the display and, further, to indicate a user'"'"'s response to an indicated question. A voice synthesizer provides tutorial instruction, operational directions, and informs the user of the outcome of a completed exercise.

Claims

1. A limited function, user friendly interactive teaching apparatus, the combination comprising:

memory means for storing a first compilation of data corresponding to words and phrases to be used by the teaching apparatus and a pedagogical program comprised of a plurality of identically formatted, limited size, program units, each said program unit including screen display locations for said words and phrases to be displayed, a pointer to said first compilation of data for each word and phrase to be displayed, row and column delimiters indicating boundaries for a correct user answer and branch to addresses of subsequent program units;

a display for displaying said words and phrases, said display further provided with a position indicator;

processor means for executing said pedagogical program, program unit by program unit, said processor means fetching said words and phrases from said first compilation of data and exhibiting them on said display in accordance with said screen display locations; and

x-y movement means for causing said position indicator to move on said display.

2. The invention as defined in claim 1 wherein said memory means additionally stores data corresponding to phonemes to be used with at least one of said words and phrases by said teaching apparatus;

and further comprising;

speaker means for audibly providing said phonemes to a user upon the display of said one of said words and phrases.

3. The invention as defined in claim 1 wherein said position indicator is a cursor and said x-y movement means is a joystick for providing direction input in only the x and y directions, and further includes a selector input means for providing an indication to said processor means when said cursor is at a desired point on said display, the joystick and selector input means being the sole user inputs to the teaching apparatus during operation.

4. The invention as defined in claim 1 wherein each said program unit further includes a memory voice point for phoneme strings to be broadcast with said words and phrases and speaker means for broadcasting said phoneme strings.

5. The invention as defined in claim 4 wherein said processor means fetches phoneme strings from said first compilation of data under control of pointers in said program unit, and assemblies said phoneme strings into groups to comprise human-intelligible words and phrases for broadcast by said speaker means.

6. The invention as defined in claim 1 wherein each of said program units has an identical number of data fields, each said data field has a length which is variable within predetermined limits, each said data field having a boundary identified by a designated delimiter symbol.

7. The invention as defined in claim 1 wherein said words and phrases are stored with predetermined starting locations in said memory means and have ending boundaries defined by designated delimiter symbols.

8. The invention as defined in claim 1 wherein said position indicator is a touch sensitive means associated with said display, for producing x and y position signals to said processor means.

9. The invention as defined in claim 1 wherein said position indicator is comprised of a plurality of depressible buttons arranged about said display for producing position signals to said processor means.

10. The invention defined in claim 1 wherein each said program unit has a predetermined starting location in said memory means and has an ending boundary defined by a designated delimiter symbol.
