Abstract

In particular embodiments, an apparatus includes a single electrode configured to passively receive a charge displacement and a change in characteristics of electromagnetic signals in an environment. The apparatus further includes a touch sensor, coupled to the single electrode, configured to detect a first input based on the charge displacement, and a second input based on the change in characteristics of electromagnetic signals in the environment.

First claim

What is claimed is:

1. An electronic device, comprising:
a display;
an electrode disposed onto the display and configured to detect a charge displacement in response to one or more of a plurality of objects contacting the display, wherein each of the plurality of objects is associated with a different predetermined charge pattern comprising a combination of one or more of a positive charge, a negative charge, or a neutral charge;
a computer-readable non-transitory storage medium embodying instructions; and
one or more processors coupled to the computer-readable non-transitory storage medium and operable to execute the instructions to:
determine, based on the charge displacement detected by the electrode, a first object of the plurality of objects;
in response to determining the first object of the plurality of objects, launch at least one application corresponding to the first object; and
display, on the display, a performed action with respect to the at least one application, the performed action being performed utilizing the first object.

2. The electronic device of claim 1 , wherein the first object comprises a pencil, a paintbrush, an eraser, a pen, or a stylus.

3. The electronic device of claim 1 , wherein the instructions to launch the at least one application comprise instructions to launch one or more of a drawing application, a painting application, a gaming application, or a direct manipulation application.

4. The electronic device of claim 1 , wherein the instructions to display the performed action with respect to the at least one application comprise instructions to:
detect a performed action through an external material overlaying the display, the performed action being performed on the external material while overlaying the display; and
display, on the display, the performed action as performed on the external material.

5. The electronic device of claim 1 , wherein the instructions to launch the at least one application comprise instructions to launch the at least one application based on a determined context of the electronic device.

6. The electronic device of claim 5 , wherein the determined context of the electronic device comprises a current location of the electronic device.

7. A non-transitory computer-readable storage medium comprising instructions that is operable when executed by one or more processors to:
detect a charge displacement by an electrode disposed onto a display of an electronic device, wherein the electrode is configured to detect the charge displacement in response to one or more objects of a plurality of objects contacting the display, and wherein each of the plurality of objects is associated with a different predetermined charge pattern comprising a combination of one or more of a positive charge, a negative charge, or a neutral charge;
determine, based on the charge displacement, a first object of the plurality of objects;
in response to determining the first object of the plurality of objects, launch at least one application corresponding to the first object; and
display, on the display, a performed action with respect to the at least one application, the performed action being performed utilizing the first object.

8. The non-transitory computer-readable storage medium of claim 7 , wherein the first object comprises a pencil, a paintbrush, an eraser, a pen, or a stylus.

9. The non-transitory computer-readable storage medium of claim 7 , wherein the instructions to launch the at least one application comprise instructions to launch one or more of a drawing application, a painting application, a gaming application, or a direct manipulation application.

10. The non-transitory computer-readable storage medium of claim 7 , wherein the instructions to display the performed action with respect to the at least one application further comprise instructions to:
detect a performed action through an external material overlaying the display, the performed action being performed on the external material while overlaying the display; and
display, on the display, the performed action as performed on the external material.

11. The non-transitory computer-readable storage medium of claim 7 , wherein the instructions to launch the at least one application further comprise instructions to launch the at least one application based on a determined context of the electronic device.

12. The non-transitory computer-readable storage medium of claim 11 , wherein the determined context of the electronic device comprises a current location of the electronic device.

13. A method comprising:
detecting a charge displacement by an electrode disposed onto a display of an electronic device, wherein the electrode is configured to detect the charge displacement in response to one or more objects of a plurality of objects contacting the display, and wherein each of the plurality of objects is associated with a different predetermined charge pattern comprising a combination of one or more of a positive charge, a negative charge, or a neutral charge;
determining, based on the charge displacement, a first object of the plurality of objects;
in response to determining the first object of the plurality of objects, launching at least one application corresponding to the first object; and
displaying, on the display, a performed action with respect to the at least one application, the performed action being performed utilizing the first object.

14. The method of claim 13 , wherein the first object comprises a pencil, a paintbrush, an eraser, a pen, or a stylus.

15. The method of claim 13 , wherein launching the at least one application comprises launching one or more of a drawing application, a painting application, a gaming application, or a direct manipulation application.

16. The method of claim 13 , wherein displaying the performed action with respect to the at least one application further comprises:
detecting a performed action through an external material overlaying the display, the performed action being performed on the external material while overlaying the display; and
displaying, on the display, the performed action as performed on the external material.
