Abstract

An improved system and method for user input in to a computer particularly tablet computers. The improvements involve generating tactile feedback through a stylus to a user. The feedback being dependant on what virtual function the pen is providing or where the stylus is positioned relative to the information displayed on the computer display or where the curser is in the displayed information.

Claims

1. An active dynamic stylus for input into a computer comprising:

a) a stylus which can serve as a pointing device for the computer;

b) a receiver connected to the stylus for receiving electromagnetic signals from the computer device;

c) a transducer connected to the stylus and the receiver for converting the electromagnetic signals into mechanical signals detectible by a user holding the stylus.

2. The active dynamic stylus of claim 1 wherein the receiver receives the electromagnetic signals over hard wire.

3. The active dynamic stylus of claim 1 wherein:

a) the receiver is a wireless receiver for receiving electromagnetic signals transmitted wirelessly from the computer device; and

b) a battery is electrically connected to provide power to the receiver and the transducers connected to the stylus.

4. The active dynamic stylus of claim 1 wherein the stylus receives a signal to generate a mechanical signal when the computer device receives a signals from a sensing device that senses movement of the stylus thus providing feedback to the user in the form of a mechanical signal that the stylus is moving.

5. The active dynamic stylus of claim 1 wherein the stylus receives a signal to generate a mechanical signal when the pointing device crosses a virtual window border.

6. The active dynamic stylus of claim 1 wherein the stylus receives a signal to generate a mechanical signal when the pointing device crosses a virtual tool button.

7. The active dynamic stylus of claim 1 wherein the stylus receives a signal to generate a mechanical signal when the pointing device remains within the boundaries of a virtual tool button.

8. A computer system with a stylus based pointing input device comprising:

a) a computing device comprising;

an active display for receiving input from a stylus input device, and a transmitter for transmitting electro magnetic signals; and

b) an active stylus comprising;

a stylus which can serve as a pointing device for the computer,

a receiver receiving electromagnetic signals from the computing device, and

a transducer transforming the electromagnetic signal into a mechanical signal detectable by the user of the computer system holding the stylus.

9. The computer system of claim 8 wherein the computer transmitter transmits over hardwire and the receiver receives the electromagnetic signals over hard wire.

10. The computer system of claim 8 wherein:

a) the computer transmitter is a wireless transmitter;

b) the stylus receiver is a wireless receiver and the mechanical signals generated in by the transducers result from wireless signals sent by the computer transmitter and received by the stylus receiver,

c) the stylus is connected to a battery which is electrically connected to provide power to the receiver and the transducers connected to the stylus.

11. The computer system of claim 8 wherein the computer transmitter sends a signal which the stylus receives and responsively generates a mechanical signal when the computer device receives a signals from a sensing device that senses movement of the stylus thus providing feedback to the user in the form of a mechanical signal that the stylus is moving.

12. The computer system of claim 8 wherein the computer transmitter transmits and the stylus receiver receives a signal to generate a mechanical signal when the pointing device crosses a virtual window border.

13. The computer system of claim 8 wherein the computer transmitter transmits and the stylus receiver receives a signal to generate a mechanical signal when the pointing device crosses a virtual tool button.

14. The computer system of claim 8 wherein the computer transmitter transmits and the stylus receiver receives a signal to generate a mechanical signal when the pointing device remains in a virtual tool button.

15. A tablet computer system with a stylus based pointing input device comprising:

a) a tablet computing device comprising;

an active display capable of receiving input from a stylus input device, and

a wireless transmitter capable of transmitting electro magnetic signals over a short distance; and

b) an active stylus comprising;

a stylus which can serve as a pointing device for the tablet computer

a wireless receiver receiving electromagnetic signals from the tablet computing device, and

a plurality of transducers for transforming the electromagnetic signal into a mechanical signal detectable by the user of the tablet computer system holding the stylus.

16. The tablet computing device of claim 15 wherein characteristics of the mechanical signal generated by the stylus when the stylus moves across the active display is dependent of the direction of movement of the stylus.

17. The tablet computing device of claim 15 wherein the characteristics of the mechanical signal generated by the stylus when the stylus moves depends on the force of the stylus on the tablet display.

18. The tablet computing device of claim 15 wherein the characteristics of the mechanical signal generated by the stylus depends on the speed of movement of the stylus on the tablet display.

19. The tablet computing device of claim 15 wherein a mechanical signal can be generated by the stylus regardless of it position on or proximate to the tablet computer display.
