Abstract

Systems, methods, apparatuses and computer program products configured to provide sound feedback for input devices are described. Embodiments take input from a digitizer, such as input using as stylus/pen, and produce sound feedback to enhance the user'"'"'s input interface experience. Embodiments thus provide a user with a more realistic interface with an electronic device, emulating use of conventional writing implements.

Claims

1. an apparatus comprising:

one or more input devices, the one or more input devices including a digitizer configured to receive inputs via a stylus; and

one or more processors;

wherein, responsive to execution of computer readable program code accessible to the one or more processors, the one or more processors are configured to;

ascertain one or more inputs to the digitizer;

map one or more writing input characteristics selected from the group of characteristics consisting of a speed of the one or more inputs, a pressure of the one or more inputs, and a width of the one or more inputs that are indicative of a predetermined writing implement pair to select predetermined audio data of the predetermined writing implement pair;

wherein mapping one or more inputs having an increasing speed to audio data having an increasing frequency adaptively response to the speed of the one or more inputs;

mapping one or more inputs having a particular width to audio data having a predetermined amplification factor corresponding to the particular width of the one or more inputs;

mapping one or more inputs having a particular pressure to audio data having a predetermined amplification factor corresponding to the particular pressure of the one or more inputs; and

output the predetermined audio data to an audio sub-system responsive to mapping of the one or more inputs.

2. The apparatus according to claim 1, wherein the predetermined audio data comprises captured audio data of one or more writing implement pairs.

3. The apparatus according to claim 2, wherein the one or more writing implement pairs comprises a writing implement pair selected from the group consisting of a pen and a piece of paper, a pencil and a piece of paper, a marker and a whiteboard, and a piece of chalk and a chalkboard.

4. The apparatus according to claim 1, wherein to map the one or more inputs to predetermined audio data further comprises using audio digital signal processing of the predetermined audio data to emulate a predetermined writing implement pair.

5. The apparatus according to claim 4, further comprising:

a storage device storing audio data corresponding to a plurality of predetermined writing implement pairs;

wherein the one or more processors are further configured to present an application window for user selection of a predetermined writing implement pair from the plurality of predetermined writing implement pairs.

6. A computer program product comprising:

a computer readable storage medium having computer readable program code embodied therewith, the computer readable program code comprising;

computer readable program code configured to ascertain one or more inputs to a digitizer input via a stylus;

computer readable program code configured to map one or more writing input characteristics selected from the group of characteristics consisting of a speed of the one or more inputs, a pressure of the one or more inputs, and a width of the one or more inputs that are indicative of a predetermined writing implement pair to select predetermined audio data of the predetermined writing implement pair;

wherein mapping one or more inputs having an increasing speed to audio data having an increasing frequency adaptively response to the speed of the one or more inputs;

mapping one or more inputs having a particular width to audio data having a predetermined amplification factor corresponding to the particular width of the one or more inputs;

mapping one or more inputs having a particular pressure to audio data having a predetermined amplification factor corresponding to the particular pressure of the one or more inputs; and

computer readable program code configured to output the predetermined audio data to an audio sub-system responsive to the one or more inputs;

wherein the predetermined audio data comprises audio data for emulating the predetermined writing implement pair.

7. The computer program product according to claim 6, wherein the predetermined audio data comprises captured audio data of one or more writing implement pairs.

8. The computer program product according to claim 7, wherein the one or more writing implement pairs comprises a writing implement pair selected from the group consisting of a pen and a piece of paper, a pencil and a piece of paper, a marker and a whiteboard, and a piece of chalk and a chalkboard.

9. The computer program product according to claim 6, wherein the computer readable program code configured to output the predetermined audio data to an audio sub-system responsive to the one or more inputs further comprises computer readable program code configured to use audio digital signal processing of the predetermined audio data to emulate a predetermined writing implement pair.

10. The computer program product according to claim 9, further comprising:

computer readable program code configured to access a storage device storing audio data corresponding to a plurality of predetermined writing implement pairs; and

computer readable program code configured to present an application window for user selection of a predetermined writing implement pair from the plurality of predetermined writing implement pairs.

11. A method comprising:

ascertaining one or more inputs to a digitizer;

mapping one or more writing input characteristics selected from the group of characteristics consisting of a speed of the one or more inputs, a pressure of the one or more inputs, and a width of the one or more inputs of the one or more inputs that are indicative of a predetermined writing implement pair to select predetermined audio data of the predetermined writing implement pair;

wherein mapping one or more inputs having an increasing speed to audio data having an increasing frequency adaptively response to the speed of the one or more inputs;

mapping one or more inputs having a particular width to audio data having a predetermined amplification factor corresponding to the particular width of the one or more inputs;

mapping one or more inputs having a particular pressure to audio data having a predetermined amplification factor corresponding to the particular pressure of the one or more inputs; and

outputting the predetermined audio data to an audio sub-system responsive to the one or more inputs;

wherein the predetermined audio data comprises audio data for emulating the predetermined writing implement pair.

12. The method according to claim 11, wherein outputting the predetermined audio data to an audio sub-system responsive to the one or more inputs further comprises using audio digital signal processing of the predetermined audio data to emulate a predetermined writing implement pair.
