Abstract

A force-sensitive touch sensor detects location and force of touches applied to the sensor. Movement of an object touching the force-sensitive touch sensor correlates to movement of a pointer on a display device. Varying levels of force applied to the force-sensitive touch sensor are interpreted as different commands. Objects displayed on the display device can be manipulated by a combination of gestures across a surface of the force-sensitive touch sensor and changes in force applied to the force-sensitive touch sensor.

First claim

What is claimed is:

1. A device comprising:
a display;
a force-sensitive touch sensor;
at least one processor; and
one or more non-transitory computer-readable media storing computer-executable instructions that, when executed by the at least one processor, cause the at least one processor to perform acts comprising:
receiving, at the force-sensitive touch sensor, first data representing a first touch input;
causing, on the display, presentation of a control at a location on the force-sensitive touch sensor associated with the first touch input, the control including a first representation of a first area of the force-sensitive touch sensor and a second representation of a second area of the force-sensitive touch sensor, wherein the first area is associated with a first command and the second area is associated with a second command;
receiving, at the force-sensitive touch sensor, second data representing a second touch input associated with a single implement, wherein the second touch input is received at least partly within the first area of the force-sensitive touch sensor and at least partly within the second area of the force-sensitive touch sensor;
determining a first portion of the second touch input that is received within the first area of the force-sensitive touch sensor;
determining a second portion of the second touch input that is received within the second area of the force-sensitive touch sensor;
determining a first magnitude of force associated with the first portion of the second touch input;
determining a second magnitude of force associated with the second portion of the second touch input;
determining that the first magnitude is greater than the second magnitude; and
causing, based at least in part on the first magnitude being greater than the second magnitude, the first command to be performed.

2. The device of claim 1 , wherein the second touch input of the single implement is associated with a contact area of the force-sensitive touch sensor, and wherein the one or more non-transitory computer-readable media further store computer-executable instructions that, when executed by the at least one processor, cause the at least one processor to perform an act comprising:
determining a center of the contact area, and
wherein causing the first command to be performed is based at least in part on the center of the contact area being located within the first area of the force-sensitive touch sensor.

3. The device of claim 2 , wherein the one or more non-transitory computer-readable media further store computer-executable instructions that, when executed by the at least one processor, cause the at least one processor to perform acts comprising:
generating a representation of a pointer associated with the second touch input, wherein at least a portion of the pointer extends beyond a perimeter of the contact area; and
causing the representation of the pointer to be displayed on the display.

4. The device of claim 1 , wherein the one or more non-transitory computer-readable media further store computer-executable instructions that, when executed by the at least one processor, cause the at least one processor to perform an act comprising:
determining that the first magnitude of force exceeds a threshold magnitude of force, and
wherein causing the first command to be performed is based at least in part on the first magnitude of force exceeding the threshold magnitude of force.

5. The device of claim 1 , wherein a first boundary of the first area at least partially borders a second boundary of the second area.

6. A method comprising:
under control of one or more computer systems configured with executable instructions,
receiving a first touch input at a force-sensitive touch sensor;
generating a control on a display, wherein the control includes a first representation of a first area of the force-sensitive touch sensor associated with a first command and a second representation of a second area of the force-sensitive touch sensor associated with a second command;
receiving a second touch input of a single implement at the force-sensitive touch sensor, the second touch input encompassing a contact area of the force-sensitive touch sensor, wherein the contact area is at least partially within the first area and at least partially within the second area;
determining a first portion of the second touch input received at the first area;
determining a second portion of the second touch input received at the second area;
determining a first magnitude of force associated with the first portion of the second touch input;
determining a second magnitude of force associated with the second portion of the second touch input;
determining that the first magnitude of force is greater than the second magnitude of force; and
causing, based at least in part on the first magnitude being greater than the second magnitude, the first command to be performed.

7. The method of claim 6 , further comprising determining that the first magnitude of force is greater than a threshold magnitude of force, and wherein causing the first command to be performed is based at least in part on the first magnitude of force being greater than the threshold magnitude of force.

8. The method of claim 6 , further comprising determining an amount of the contact area received within the first area, and wherein causing the first command to be performed is based at least in part on the amount of the contact area received within the first area.

9. The method of claim 6 , further comprising determining a center of the contact area, and wherein causing the first command to be performed is based at least in part on the center of the contact area being located within the first area of the force-sensitive touch sensor.

10. The method of claim 6 , further comprising:
determining a first amount of the contact area received within the first area;
determining a second amount of the contact area received within the second area; and
determining that the first amount is greater than the second amount, and
wherein causing the first command to be performed is based at least in part on the first amount being greater than the second amount.

11. The method of claim 6 , further comprising generating a representation of the second touch input, wherein at least a portion of the representation of the second touch input extends beyond a perimeter of the contact area.

12. The method of claim 11 , wherein the representation is based at least in part on at least one of:
a location of the second touch input on the force-sensitive touch sensor; or
the first magnitude of force associated with the first portion of the second touch input.

13. The method of claim 6 , wherein a third portion of the contact area is received at least partially within a third area of the force-sensitive touch sensor associated with a third command, the method further comprising:
determining a third magnitude of force associated with the third portion of the second touch input; and
determining that the first magnitude of force is greater than the third magnitude of force.

14. The method of claim 6 , wherein:
the first area and the second area are separately addressable areas on the force-sensitive touch sensor; and
the first area and the second area are separated from another between a distance of about one millimeter to about five millimeters.

15. A device comprising:
a display;
a force-sensitive touch sensor;
at least one processor; and
one or more non-transitory computer-readable media storing computer-executable instructions that, when executed
