Abstract

A network of terminals, where each terminal is operable by a student in a group as a response apparatus, is in contemporaneous communication with a teacher station. The modes of operation include visual, i.e. hand writing, hand drawing and typing, as well as audio, in particular the voice of the user, which may contemporaneously accompany the visual, such as when explaining what is being drawn. Such an apparatus can also be used by a teacher to author a lesson, including graphics and audio, providing information and questions which are recorded at the teacher station. The communication means between the student apparatuses and the teacher'"'"'s station is in a preferred embodiment of the invention via an 802.11 wireless gateway when the students are in the same room as the teacher or in close proximity, or via the Internet especially in the case where individual students are remotely located from the teacher.

Claims

1. An electronic educational system serving a teacher and at least one student comprising:

a student terminal for each student, each student terminal including graphic notation forming means comprising an electronic pen and a set of alpha-numeric keys, each student terminal also including a display usable to provide concurrent representations of response inputs from that student, each such student terminal being usable to display handwritten graphic components of the student response inputs and entered on the display by use of the electronic pen, together with alpha-numeric components of the student response inputs and entered on the display by use of the set of alpha-numeric keys;

a teacher'"'"'s station including a computer and screen and network communication connections to receive and to concurrently display the graphic component and the alpha-numeric component inputs of the response from each of the students received in real time, and to provide lesson and question data input to each student terminal;

a communication network coupling each student terminal to the teacher station for bi-directional exchange of data; and

audio communications means at each of the student terminals and the teacher'"'"'s station, the audio communications means being operable contemporaneously with the graphic notation means and wherein a time duration of an audio input of each student terminal is displayed on the teacher'"'"'s screen on an ongoing basis.

2. The system of claim 1, wherein the teacher station screen includes means for concurrently displaying in organized sequence the separate graphic notations from each of the students.

3. The system of claim 1, wherein the rate of communication of the graphic notations at the terminal of each student to the teacher'"'"'s station is stroke-by-stroke.

4. The system of claim 1, wherein the rate of communication of the graphic notations from the electronic pen to the teacher'"'"'s station is segment-by-segment.

5. The system of claim 1, wherein each student terminal further includes a handheld graphic information capturing apparatus.

6. The system of claim 1, wherein the communication protocol for the graphic and audio data inputs to the teacher'"'"'s station employs multiplexing circuits enabling contemporaneous communication of the graphic notation and audio input data.

7. The system of claim 1, wherein the audio communication means of each student includes a unidirectional microphone.

8. The system of claim 1, wherein the teacher'"'"'s station further includes program approved responses for any combination of graphic notation inputs, including handwriting, hand drawing and typing, and comparison means for indicating the correct graphic notation inputs.

9. The system of claim 1, wherein the teacher'"'"'s station further includes program approved responses for musical sound input, and comparison means for indicating correct audio input responses.

10. The system of claim 1, wherein the computer at the teacher'"'"'s station includes program instructions for converting the manual entry of a symbol by the teacher on the computer screen opposite the name of a student into the grade to be awarded for the student'"'"'s input.

11. The system of claim 10, wherein the computer at the teacher'"'"'s station includes program instructions for communicating grading information to the student terminals.

12. The system of claim 1, wherein the teacher station includes a class display placed in the class where students are located and which is in communication with the computer at the teacher station for reproducing inputs including those originating from a student terminal on a scale perceivable by all the students in the class.

13. The system of claim 12, wherein the graphic notations that are unaccompanied by audio are reproduced at a faster rate than when created on the student terminal.

14. The system of claim 12, wherein periods of coincident hesitation of both graphic and audio inputs on student terminals larger than a specified duration, are eliminated when reproduced.

15. The system of claim 1, wherein a communication protocol for coupling the plurality of student terminals to the teacher'"'"'s station is a 802.11 wireless local area network.

16. The system of claim 1, wherein the communication network coupling each student terminal to the teacher'"'"'s station is the Internet.

17. The system of claim 16, wherein each student terminal has its own connection via a TCP/IP server for transmitting pen strokes, keystrokes and voice input.

18. The system of claim 16, wherein the student terminals each have their own set of separate TCP/IP connection for transmitting pen strokes, keystrokes and voice input.

19. An electronic educational system enabling a teacher to author a variety of educational and program material comprising:

a teacher'"'"'s station including a computer, a screen, and audio communications means;

terminals each including graphic notation means including an electronic pen and a set of alpha-numeric keys, each such terminal also including a display and being usable to display handwritten graphic components and alpha-numeric components of response inputs entered on the display as well as audio communication input devices operable contemporaneously with the graphic notation means and wherein a time duration of an audio input of each terminal is displayed on the teacher'"'"'s station screen on an ongoing basis;

a communication circuit coupling each terminal to the computer for receiving and displaying the graphic component and the alpha-numeric component inputs from each terminal in real time and for receiving and reproducing the audio communications from each terminal; and

a class display in communication with the computer at the teacher station for reproducing inputs originating from each terminal while preserving the time relationships between the graphic and audio inputs.

20. A psychology testing system enabling mental chronometry testing of persons by a tester, comprising:

a terminal for each person to be tested, each terminal including graphic notation means including an electronic pen, a set of alpha-numeric keys, each terminal also including a display providing concurrent representations of the response inputs from that person and being usable to display handwritten graphic components, together with alpha-numeric components of response inputs of each person to be tested;

each terminal also including audio communication means;

a communication network coupling each person'"'"'s terminal to a tester'"'"'s station; and

the tester'"'"'s station including a computer, a screen, audio communications means, and network communication connections for providing information and request data input to the terminals and for receiving and concurrently display the graphic component and the alpha-numeric component response inputs from each person to be tested in real time and for recording the inputs as well as the reaction and execution times of each person'"'"'s inputs in real time, the audio communications means being operable contemporaneously with the graphic notation means and wherein a time duration of an audio input of each terminal is displayed on the tester'"'"'s screen on an ongoing basis.
