Abstract

Various techniques may be employed for assigning user inputs such as a touch on a touchscreen to various input controls such as buttons or other features provided on a touchscreen. One example input assignment technique is a nearest neighbor technique, whereby a touch may, for example, be assigned to an input control that is positioned closest to the touch location. Another example input assignment technique is an angle and distance technique, whereby a touch may, for example, be assigned to an input control based on an angle and a distance of the touch relative to a prior touch.

Claims24

Dependent claims

A system configured for input control assignment, the system comprising:

a touchscreen that at least temporarily displays at least a first input control and a second input control,
one or more processors;
memory having stored therein angle and distance information associated with the first input control, wherein the angle and distance information indicates, for each of one or more ranges of one or more angles relative to the first input control, associated distance ranges, the memory further having stored therein computer instructions that, upon execution by the one or more processors, cause the system to perform operations comprising:
detecting a first touch at a first screen location;
assigning the first touch to the first input control;
detecting a second touch at a second screen location;
calculating an angle and a distance of the second screen location relative to the first screen location;
determining, based on the angle and distance information, that the calculated angle is within a first range of one or more angles indicated by the angle and distance information;
identifying, based on the angle and distance information, a first plurality of distance ranges associated with the first range of one or more angles, the first plurality of distance ranges comprising a first distance range and a second distance range;
determining which one of the first plurality of distance ranges includes the calculated distance;
assigning the second touch to the first input control when the first distance range includes the calculated distance;
and
assigning the second touch to the second input control when the second distance range includes the calculated distance.

10 more elements

One or more non-transitory computer-readable storage media having stored thereon instructions that, upon execution on at least one compute node, cause the at least one compute node to perform operations comprising:

detecting a first touch at a first screen location;
assigning the first touch to a first input control;
detecting a second touch at a second screen location;
calculating an angle and a distance of the second screen location relative to the first screen location;
identifying a plurality of distance ranges associated with the calculated angle, the plurality of distance ranges comprising a first distance range and a second distance range;
determining which one of the plurality of distance ranges includes the calculated distance;
assigning the second touch to the first input control when the first distance range includes the calculated distance;
and
assigning the second touch to a second input control when the second distance range includes the calculated distance.
