Abstract

An embodiment provides a method, including detecting, using a processor, pen input to a surface of an electronic device; accessing, using a processor, one or more other inputs associated in time with the pen input; and adjusting, using a processor, a location of a display output representing the pen input using both of the detected pen input and the one or more other inputs. Other aspects are described and claimed.

Claims

1. A method, comprising:

detecting, using a processor, pen input to a surface of an electronic device, wherein the electronic device provides an associated location of a display output representing pen input;

accessing, using a processor, one or more other inputs associated in time with the pen input, wherein the one or more other inputs identify an orientation of a pen used to provide the pen input with respect to the surface of the electronic device based upon a tilt orientation of the electronic device with respect to a user, an orientation of the electronic device in an environment, and a centroid of a part of a hand of the user to a contact point of the pen based on handedness of the user, and wherein the one or more other inputs select a new location of a display output different from the associated location of a display output; and

dynamically adjusting, using a processor, the location of a display output representing the pen input as pen inputs are detected, wherein the adjusted location corresponds to the new location of a display output and an offset calculated based upon the one or more other inputs.

2. The method of claim 1, wherein the part of hand of the user comprises palm input at the surface.

3. The method of claim 1, wherein the orientation of the electronic device is based upon data derived from one or more sensors.

4. The method of claim 1, wherein the adjusting comprises changing a location for the display output to be further distal to the user with respect to the detected pen input.

5. The method of claim 4, wherein the adjusting includes calculating a distal point with respect to the user using straight line approximation.

6. The method of claim 5, wherein the calculating includes determining a centroid of palm input, and further wherein the straight line approximation takes into account the centroid of palm input and a point of contact associated with the pen input to the surface.

7. The method of claim 1, wherein the one or more other inputs comprise pen orientation data derived from the pen.

8. The method of claim 5, wherein the distal point with respect to the user is offset from a point of contact associated with the pen input to the surface by a predetermined amount.

9. The method of claim 8, wherein the predetermined amount is between about 0.1 mm and about 3 mm.

10. A device, comprising:

a surface accepting pen input;

a display;

a processor operatively coupled to the surface and the display; and

a memory storing instructions that are executable by the processor to;

detect pen input to the surface, wherein the display provides an associated location of a display output representing pen input;

access one or more other inputs associated in time with the pen input, wherein the one or more other inputs identify an orientation of a pen used to provide the pen input with respect to the surface based upon a tilt orientation of the electronic device with respect to a user, an orientation of the electronic device in an environment, and a centroid of a part of a hand of the user to a contact point of the pen based on handedness of the user, and wherein the one or more other inputs select a new location of a display output different from the associated location of a display output; and

dynamically adjust the location of a display output representing the pen input as pen inputs are detected, wherein the adjusted location corresponds to the new location of a display output and an offset calculated based upon the one or more other inputs.

11. The device of claim 10, wherein the part of hand of the user comprise palm input at the surface.

12. The device of claim 10, further comprising one or more sensors;

wherein the orientation of the electronic device is derived from the one or more sensors.

13. The device of claim 10, wherein to adjust comprises changing a location for the display output to be further distal to the user with respect to the detected pen input.

14. The device of claim 13, wherein to adjust includes calculating a distal point with respect to the user using straight line approximation.

15. The device of claim 14, wherein the calculating includes determining a centroid of palm input, and further wherein the straight line approximation takes into account the centroid of palm input and a point of contact associated with the pen input to the surface.

16. The device of claim 10, wherein the one or more other inputs comprise pen orientation data derived from the pen.

17. The device of claim 14, wherein the distal point with respect to the user is offset from a point of contact associated with the pen input to the surface by a predetermined amount.

18. The device of claim 17, wherein the predetermined amount is between about 0.1 mm and about 3 mm.

19. The device of claim 10, wherein the display and the surface are provided in the form of a touch screen unit.

20. A computer program product, comprising:

a computer readable storage device storing code that is executable by a processor of an electronic device, the code comprising;

code that detects pen input to a surface of an electronic device, wherein the electronic device provides an associated location of a display output representing pen input;

code that accesses one or more other inputs associated in time with the pen input, wherein the one or more other inputs identify an orientation of a pen used to provide the pen input with respect to the surface of the electronic device based upon a tilt orientation of the electronic device with respect to a user, an orientation of the electronic device in an environment, and a centroid of a part of a hand of the user to a contact point of the pen based on handedness of the user, and wherein the one or more other inputs select a new location of a display output different from the associated location of a display output; and

code that dynamically adjusts the location of a display output representing the pen input as pen inputs are detected, wherein the adjusted location corresponds to the new location of a display output and an offset calculated based upon the one or more other inputs.
