Pen switching between active and passive status
View Patent ↗An embodiment provides a method, including: identifying, using a processor, a pen characteristic; identifying, using a processor, an inability to communicate between the pen and an input component using the pen characteristic; and responsive to detecting the inability, disabling a pen feature. Other embodiments, including systems, devices and products, are described and claimed.
1. A method, comprising:
identifying, using a processor, a pen characteristic of an active pen;
identifying, using a processor, an inability to communicate between the active pen and an input surface using the pen characteristic; and
responsive to establishing an inability to communicate between the active pen and the input surface, disabling a pen data communication feature of the input surface and operating the input surface in a passive pen mode.
2. The method of claim 1 , further comprising communicating passive pen inputs responsive to said disabling.
3. The method of claim 1 , further comprising:
establishing a data connection between the active pen with the input surface.
4. The method of claim 3 , wherein said establishing comprises establishing a short range wireless connection between the active pen and a device in which the input surface is housed.
5. The method of claim 1 , further comprising communicating, using a short range wireless connection, data between the active pen and a device having the input surface.
6. The method of claim 5 , wherein said data comprises pen information selected from the group consisting of effective capacitance, nib area, battery level, tip pressure, button status, pen capability, and pen identification.
7. The method of claim 1 , wherein said identifying, using a processor, a pen characteristic, further comprises identifying a characteristic selected from the group consisting of effective capacitance, nib area, and tip pressure.
8. The method of claim 1 , further comprising:
responsive to detecting the inability, switching to another pen data channel.
9. The method of claim 8 , wherein said switching is iterated through a predetermined list.
10. The method of claim 1 , further comprising:
responsive to detecting the inability, selecting another pen data channel that matches the input surface.
11. A device, comprising:
an input surface accepting active pen input;
a display;
a processor operatively coupled to the input surface and the display; and
a memory storing instructions that are executable by the processor to:
identify a pen characteristic of an active pen;
identify an inability to communicate between the active pen and the input surface using the pen characteristic; and
responsive to establishing an inability to communicate between the active pen and the input surface, disable a pen feature data communication feature of the input surface and operate the input surface in a passive pen mode.
12. The device of claim 11 , further comprising communicating a signal to the pen for disabling the active pen.
13. The device of claim 11 , wherein the instructions are further executable by the processor to establish a data connection between the pen with the input surface.
14. The device of claim 13 , wherein to establish a data connection comprises establishing a short range wireless connection between the active pen and the device.
15. The device of claim 14 , wherein the instructions are further executable by the processor to receive data using said short range wireless connection.
16. The device of claim 14 , wherein the data using said short range wireless connection comprises pen information selected from the group consisting of effective capacitance, nib area, battery level, tip pressure, button status, pen capability, and pen identification.
17. The device of claim 16 , wherein to identify a pen characteristic comprises identifying a characteristic selected from the group consisting of effective capacitance, nib area, and tip pressure.
18. The device of claim 11 , wherein the instructions are further executable by the processor to:
responsive to detecting the inability, communicate a signal to the active pen for switching to another pen input data channel.
19. The device of claim 18 , wherein the signal to the active pen indicates another pen input data channel that matches the input surface.
20. A computer program product, comprising:
a storage device that stored code that is executable by a processor and comprises:
code that identifies a pen characteristic of an active pen;
code that identifies an inability to communicate between the active pen and an input surface using the pen characteristic; and
code that, responsive to establishing an inability to communicate between the active pen and the input surface, disables a pen data communication feature of the input surface to operate the input surface in a passive pen mode.
