Abstract

A method of illustrating audio signal strength includes at a portable computer device having one or more processors and memory storing programs executed by the one or more processors, collecting audio signal using the portable computer device; determining strength of the collected audio signal; computing an illustrative scale that corresponds to the audio signal strength using a mapping function; and superimposing the audio signal strength with the illustrative scale on a graphic area, wherein the graphic area includes an initial sub-area.

First claim

What is claimed is:

1. A method of illustrating audio signal strength comprising:
at a portable computer device having one or more processors and memory storing programs executed by the one or more processors,
collecting audio signal using the portable computer device;
determining strength of the collected audio signal;
computing an illustrative scale that corresponds to the audio signal strength using a mapping function; and
superimposing the audio signal strength with the illustrative scale on a graphic area, wherein the graphic area includes an initial sub-area,

wherein the mapping function is set as R=2r max √{square root over (x)}−r max x+r button , wherein x ε[0,1], R denotes the illustrative scale of the audio signal strength, x denotes the audio signal strength, r button denotes a dimension of the initial sub-area, and r max denotes the dimension of the graphic area subtracted by the dimension of the initial sub-area.

2. The method of illustrating audio signal strength of claim 1 , further comprises:
detecting whether an audio recording button on the portable computer device is pressed for collecting the audio signal, wherein the audio recording button is displayed within the initial sub-area.

3. The method of illustrating audio signal strength of claim 1 , wherein
dimensions of the graphic area and the initial sub-area are configured according to screen pixels of the portable computer device.

4. The method of illustrating audio signal strength of claim 1 , wherein
the graphic area, the initial sub-area, and illustration of the audio signal strength are configured to be concentric circles, where the circle that illustrates the audio signal strength has a radius that equals to the illustrative scale.

5. The method of illustrating audio signal strength of claim 1 , wherein
the graphic area is drawn in a first color, and the illustration of the audio signal strength is drawn in a second color.

6. A system of illustrating audio signal strength, comprising:
one or more processors;
memory; and
one or more programs stored in the memory and configured for execution by the one or more processors, the one or more programs including instructions for:
collecting audio signal using a portable computer device;
determining strength of the collected audio signal;
computing an illustrative scale that corresponds to the audio signal strength using a mapping function; and
superimposing the audio signal strength with the illustrative scale on a graphic area, wherein the graphic area includes an initial sub-area,
wherein the mapping function is set as R=2r max √{square root over (x)}−r max x+r button , wherein x ε[0,1], R denotes the illustrative scale of the audio signal strength, x denotes the audio signal strength, r button denotes the dimension of the initial sub-area, and r max denotes the dimension of the graphic area subtracted by the dimension of the initial sub-area.

7. The system of illustrating audio signal strength of claim 6 , wherein the one or more programs further comprises:
detecting whether an audio recording button on the portable computer device is pressed for collecting the audio signal, wherein the audio recording button is displayed within the initial sub-area.

8. The system of illustrating audio signal strength of claim 6 , wherein
dimensions of the graphic area and the initial sub-area are configured according to screen pixels of the portable computer device.

9. The system of illustrating audio signal strength of claim 6 , wherein
the graphic area, the initial sub-area, and illustration of the audio signal strength are configured to be concentric circles, where the circle that illustrates the audio signal strength has a radius that equals to the illustrative scale.

10. The system of illustrating audio signal strength of claim 6 , wherein
the graphic area is drawn in a first color, and the illustration of the audio signal strength is drawn in a second color.

11. A non-transitory computer readable storage medium, storing one or more programs for execution by one or more processors of a system of illustrating audio signal strength including instructions for:
collecting audio signal using a portable computer device;
determining strength of the collected audio signal;
computing an illustrative scale that corresponds to the audio signal strength using a mapping function; and
superimposing the audio signal strength with the illustrative scale on a graphic area, wherein the graphic area includes an initial sub-area,
wherein the mapping function is set as R=2r max √{square root over (x)}−r max x+r button , wherein x ε[0,1], R denotes the illustrative scale of the audio signal strength, x denotes the audio signal strength, r button denotes the dimension of the initial sub-area, and r max denotes the dimension of the graphic area subtracted by the dimension of the initial sub-area.

12. The non-transitory computer readable storage medium of claim 11 , wherein the one or more programs further comprises:
detecting whether an audio recording button on the portable computer device is pressed for collecting the audio signal, wherein the audio recording button is displayed within the initial sub-area.

13. The non-transitory computer readable storage medium of claim 11 , wherein
dimensions of the graphic area and the initial sub-area are configured according to screen pixels of the portable computer device.

14. The non-transitory computer readable storage medium of claim 11 , wherein
the graphic area, the initial sub-area, and illustration of the audio signal strength are configured to be concentric circles, where the circle that illustrates the audio signal strength has a radius that equals to the illustrative scale.

15. The non-transitory computer readable storage medium of claim 11 , wherein
the graphic area is drawn in a first color, and the illustration of the audio signal strength is drawn in a second color.
