Abstract

In some examples, an electronic device may present a user interface that is configured to be controlled using a thumb of a single hand that is holding the device. For instance, the interface may present a plurality of selectable items, each of which may correspond to a respective one of a plurality of touch input areas on the display. In some cases, the touch input areas are within reach of the thumb, while the selectable items may be displayed on an area of the display that is not within reach of the thumb. The thumb may be pressed against the display surface with a force greater than a force threshold to select one of the selectable items. Thus, the thumb may be used to interact with the interface while remaining in contact with the display surface, enabling the user to maintain a grip on the device.

4. The portable electronic device of claim 1, wherein the location is a first location in the content-free buffer area, and the operations further comprising, visually distinguishing the selectable item from one or more other selectable items of the one or more selectable items based at least in part on the third data representing the second touch input within the content-free buffer area.

5. The portable electronic device of claim 1, wherein presenting the user interface via the display is further based at least in part on determining that the first force associated with the first touch input exceeds the force threshold for a length of time greater than a time threshold.

6. The portable electronic device of claim 1, wherein determining the content-free buffer area further comprises:

determining a size of the object on the display surface; and

configuring, based at least in part on the size of the object, the content-free buffer area.

7. A method comprising:

receiving a touch input via a display surface of a display panel of a device;

determining, based at least in part on the touch input, a content-free buffer area on the display surface;

causing, based at least in part on the force exceeding the force threshold, presentation of one or more selectable items via the display surface outside of the content-free buffer area of the display surface.

8. The method as recited in claim 7, wherein causing presentation of the one or more selectable items outside of the content-free buffer area of the display surface is further based at least in part on determining that the first force associated with the touch input exceeds the force threshold for a length of time greater than a time threshold.

9. The method as recited in claim 7, wherein the touch input is a first touch input, the sensor data is first sensor data, and further comprising:
