Pointer System for Context Based Feedback

1 . A method for executing a computer program on a processor to provide feedback based on received pointer input, the method comprising:

determining a context for the pointer input;

selecting audio data corresponding to the context;

tuning the audio data based on the pointer input; and

providing sound based on the tuned audio data.

2 . The method of claim 1 , further comprising:

changing a friction coefficient of a pointer based on the received pointer input.

3 . The method of claim 1 , wherein tuning the audio data is based on a pressure applied through a pointer to an interactive display.

4 . The method of claim 1 , wherein tuning the audio data is performed dynamically based on at least a selected one of:

pointer speed; and

pointer acceleration.

5 . The method of claim 1 , wherein tuning the audio data comprises:

dynamically changing a speed of playback based on a speed of a pointer to affect a frequency of the provided sound.

6 . The method of claim 1 , wherein:

the provided sound simulates a sound of a writing utensil writing on paper.

7 . The method of claim 1 , wherein:

the provided sound simulates an eraser rubbed on paper.

8 . An input system for an information handling system, the input system comprising:

a transducer for determining at least one characteristic of pointer input;

a sound generator; and

a processor programmed for:

tuning sound data based on the at least one characteristic of pointer input, wherein the sound data is for an input context;

causing tuned sound based on the tuned sound data to be played from the sound generator.

9 . The input system of claim 8 , wherein tuning the sound occurs substantially in real time based on the at least one characteristic of the pointer input.

10 . The input system of claim 8 , wherein the at least one characteristic of pointer input comprises a physical pressure applied through a pointer.

11 . The input system of claim 9 , wherein the at least one characteristic of pointer input is selected from:

a pointer speed; and

a pointer acceleration.

12 . The input system of claim 8 , further comprising:

an active stylus.

13 . The input system of claim 12 , wherein the active stylus comprises a sound generator.

14 . The input system of claim 12 , wherein the active stylus comprises a voltage source for affecting ridges on a piezoelectric tip.

15 . An information handling system comprising:

an interactive display for dynamically receiving pointer input;

a processor enabled for:

determining a context of the pointer input;

determining a sound that is responsive to the pointer input for the context;

tuning the sound in response to the dynamically received pointer input; and

transmitting data causing sound generation to provide audible output based on the tuned sound.

16 . The information handling system of claim 15 , wherein tuning the sound comprises altering the frequency of the sound based on a measured speed of the pointer.

17 . The information handling system of claim 15 , further comprising:

a pointer comprising:

a gyroscope; and

an accelerometer.

18 . The information handling system of claim 17 , the pointer further comprising:

a sound generator for providing the audible output.

19 . The information handling system of claim 18 , wherein the pointer further comprises a transducer, wherein tuning the sound is in response to data from the transducer or in response to the dynamically received pointer input.

20 . The information handling system of claim 17 , wherein the pointer further comprises:

a location emitter;

a piezoelectric tip; and

a voltage source for applying voltage to the piezoelectric tip.
