Abstract

A method activates different interactive functions based on a classification of vibro-acoustic signals resulting from touch events with finger parts of a user. A primary function is trigger when an interactive element on a touch screen is touched with a finger tip of the user. An auxiliary function is launched when the interactive element is touched with a knuckle or fingernail of the user. The touch events result in generating the vibro-acoustic signals. The vibro-acoustic signals are classified and used to distinguish what finger part was used based on the classification of the vibro-acoustic signals.

Claims

1. A method for activating different interactive functions, the method comprising:

triggering a primary function related to an interactive element on a touch screen when a user interacts with the interactive element using any one of finger parts of the user; and

launching an auxiliary function related to the interactive element when the user interacts with the interactive element using another one of the finger parts of the user.

2. The method of claim 1, wherein the finger parts include a finger tip, a knuckle and fingernail.

3. The method of claim 1, wherein said any one of finger parts is a finger tip.

4. The method of claim 1, wherein said another one of finger parts is a knuckle or fingernail.

5. The method of claim 1, further comprising:

capturing touch events with the finger parts of the user, wherein the touch events result in generating unique vibro-acoustic signals;

distinguishing what finger part was used using the vibro-acoustic signals; and

selectively activating the primary function or the auxiliary function upon distinguishing the finger parts.

6. The method of claim 5, wherein said distinguishing what finger part was used comprises:

classifying the vibro-acoustic signals to detect the finger parts used to touch the interactive element.

7. The method of claim 1, wherein the interactive element is an email and a touch of the email with another finger part of the user causes a context menu to appear with an additional option.

8. The method of claim 7, wherein the additional option comprises reply, reply all, forward, print, archive, delete or any combination thereof.

9. The method of claim 1, wherein the interactive element is a photo and a touch of the photo with another finger part of the user causes a context menu to appear with an additional option.

10. The method of claim 9, wherein the additional option comprises email, print, modify, duplicate, post to web, delete or any combination thereof.

11. The method of claim 1, wherein the interactive element is a text and a touch and drag over a region of the text with another finger part of the user makes the selection of the text.

12. The method of claim 11, further comprising:

making an appearance of a context menu with an additional option following the selection,

wherein the additional option comprises copy, cut, paste, delete or any combination thereof.

13. The method of claim 1, wherein the interactive element is a text and a touch and drag over a region of the text with another finger part of the user makes to highlight the text.

14. The method of claim 1, wherein the interactive element is an image and a touch and drag over a region of the image with another finger part of the user makes to select a sub-region of the image.

15. The method of claim 14, further comprising:

making an appearance of a context menu with an additional option following the selection,

wherein the additional option comprises copy, crop, modify, save, or any combination thereof.

16. The method of claim 1, wherein the interactive element is an image and a touch and drag over a region of the image with another finger part of the user makes to lasso select the image.

17. The method of claim 16, further comprising:

making an appearance of a context menu with an additional option following the selection,

wherein the additional option comprises copy, crop, modify, save, or any combination thereof.

18. The method of claim 1, wherein the finger parts of the user are used as tools for different drawing actions in a drawing mode.

19. The method of claim 18, wherein a finger tip is used as a thick brush in the drawing mode.

20. The method of claim 18, wherein a knuckle is used as a fine marker in the drawing mode.

21. The method of claim 18, wherein a finger tip is used as a highlighter marker in the drawing mode.

22. The method of claim 18, wherein a knuckle is used for erasing in the drawing mode.

23. The method of claim 1, wherein the finger parts of the user are used as onscreen movement controls in a game.

24. The method of claim 23, wherein a finger tip is used for a regular player movement.

25. The method of claim 23, wherein a knuckle is used for a directional player movement in a crouched position.

26. The method of claim 23, wherein a fingernail is used to run an in-game character.

27. The method of claim 23, wherein a fingernail is used to jump an in-game character.

28. The method of claim 1, wherein the finger parts of the user are used for auxiliary actions in a game in concert with each other.

29. The method of claim 28, wherein a fingernail is used for primary weapon fire and a knuckle or fingernail is used for alternative weapon mode.

30. A computing system comprising:

a touch screen configured to display an interactive element;

a touch event detector configured to detect touch events in which the interactive element is touched by a first or a second finger part of a user, wherein the touch events result in generating vibro-acoustic signals; and

a vibro-acoustic classifier configured to classify the vibro-acoustic signals and allow the computing system to selectively activate a primary function or an auxiliary function related to the interactive element depending on the classified vibro-acoustic signals.

31. The computing system of claim 30, the vibro-acoustic classifier distinguishes which finger parts touched the interactive element based on the classification of the vibro-acoustic signals.

32. The computing system of claim 30, wherein the finger parts include a finger tip, a knuckle and fingernail.

33. The computing system of claim 30, wherein said any one of finger parts is a finger tip.

34. The computing system of claim 30, wherein said another one of finger parts is a knuckle or fingernail.
