Abstract

Techniques for navigating through a user interface with a force-sensitive touch sensor are described. In some implementations, the force-sensitive touch sensor is also a display that presents the user interface. Touches on the force-sensitive touch sensor may be interpreted as indicating a vector direction based on the location of the touch and a vector magnitude based on the force of the touch. For instance, when a user navigates through a collection of photographs on a device having a force-sensitive touch sensor, the vector direction may determine if the user is scrolling forwards or backwards through the photographs and the vector magnitude may determine how rapidly the scrolling occurs. The user may also navigate through a hierarchy of folders and files using touch and force. Selection of a folder and application of force exceeding a threshold may result in display of the contents of a most commonly accessed subfolder or file.

Claims

1. One or more non-transitory computer-readable media storing computer-executable instructions that, when executed, cause one or more processors to perform acts comprising:

detecting a touch on a force-sensitive touch-screen display of an electronic device during display of a content item on the electronic device, the content item belonging to an ordered set of multiple content items;

measuring a force of the touch on the force-sensitive touch-screen display;

interpreting the touch as a vector having (i) a direction determined at least in part by an angle of a line connecting a reference location at the middle of the force-sensitive touch-screen display to a location of the touch, and (ii) a magnitude determined at least in part by the force of the touch;

determining a direction of scrolling through the ordered set of multiple content items based at least in part on the direction of the vector;

determining a scroll rate at which one of the multiple content items displayed on the electronic device is replaced by another of the ordered set of multiple content items, wherein the scroll rate is proportional to the magnitude of the vector; and

presenting, during the scrolling, based at least in part on the scroll rate, a collapsed list that comprises an abbreviated representation of at least a portion of the multiple content items, wherein a level of abbreviation of the collapsed list is based at least in part on the magnitude of the vector.

2. One or more non-transitory computer-readable media as recited in claim 1, wherein the force-sensitive touch-screen display comprises an interpolating force-sensitive resistance array.

3. One or more non-transitory computer-readable media as recited in claim 1, wherein the scroll rate is directly proportional to the magnitude of the vector.

4. One or more non-transitory computer-readable media storing computer-executable instructions that, when executed, cause one or more processors to perform acts comprising:

detecting a touch on a force-sensitive touch sensor of an electronic device during display of content on the electronic device, wherein the displayed content comprises a series of content items that comprises at least photographs;

measuring a force of the touch on the force-sensitive touch sensor;

interpreting the touch as a vector having (i) a direction determined at least in part by comparing a location of the touch to a reference location, and (ii) a magnitude determined at least in part by the force of the touch;

changing the displayed content based at least in part on the vector having the direction and the magnitude;

selecting, by an image recognition algorithm from the series of content items, a representative image that is representative of at least a subset of the series of content items; and

displaying the representative image on the display during the change, the representative image representing one or more of the content items in the series of content item.

5. One or more non-transitory computer-readable media as recited in claim 4, wherein the force-sensitive touch sensor comprises an interpolating force-sensitive resistance array.

6. One or more non-transitory computer-readable media as recited in claim 4, wherein the force-sensitive touch sensor comprises a touch-screen display that displays the content on the electronic device.

7. One or more non-transitory computer-readable media as recited in claim 4, wherein the direction of the vector is a direction of a line from the reference location to the location of the touch.

8. One or more non-transitory computer-readable media as recited in claim 4, wherein the reference location is the center of the force-sensitive touch sensor.

9. One or more non-transitory computer-readable media as recited in claim 4, wherein the changing the displayed content comprises changing a rate at which the content scrolls across a display of the electronic device, and wherein the rate of the changing the displayed content is proportional to the magnitude of the vector.

10. One or more non-transitory computer-readable media as recited in claim 4, wherein changing the displayed content comprises causing a displayed photograph to change to another photograph based at least in part on the vector.

30. One or more computer-readable media as recited in claim 4, wherein the representative image is displayed when the force exceeds a threshold.

31. One or more computer-readable media as recited in claim 4, wherein the representative image comprises a first letter or number of an attribute associated with the one or more of the content items.

11. An electronic device, comprising:

one or more processors;
