Abstract
Methods and devices for tracking continuous touch events, such as drag operations, across adjacent capacitive touch surfaces. The adjacent capacitive touch surfaces may include a foldable touch screen having a hinged area between the two capacitive touch surfaces. The adjacent capacitive touch surfaces may include separate touch screens separated by a gap. The methods and devices may enable hover detection, predictive continuation of a touch operation, and simultaneous touch resolution.
Claims19
A method of tracking drag interaction with adjacent touch screens, comprising:
- tracking, through a first capacitive touch surface, a continuous touch event;
- during the continuous touch event, determining that a touch event location enters a first edge zone proximate a second capacitive touch surface;
- and
- while the touch event location is in the first edge zone, using a relaxed threshold for tracking the continuous touch event and detecting transition of the continuous touch event to the second capacitive touch surface,
- wherein using the relaxed threshold includes lowering a threshold for determining that capacitive sensor readings constitute a continued touch from a regular threshold to a lower threshold, so as to include a hover event as the continued touch.
A computing device comprising:
- a first capacitive touch surface;
- a second capacitive touch surface;
- one or more processing units;
- and
- memory storing processor-executable instructions that, when executed by the one or more processing units, are to cause the one or more processing units to:
- track, through the first capacitive touch surface, a continuous touch event,
- during the continuous touch event, determine that a touch event location enters a first edge zone proximate the second capacitive touch surface, and
- while the touch event location is in the first edge zone, use a relaxed threshold for tracking the continuous touch event and detecting transition of the continuous touch event to the second capacitive touch surface,
- wherein the processor-executable instructions, when executed, are to cause the one or more processing units to use the relaxed threshold by lowering a threshold for determining that capacitive sensor readings constitute a continued touch from a regular threshold to a lower threshold, so as to include a hover event as the continued touch.
A non-transitory computer-readable medium storing processor-executable instructions that, when executed by one or more processors, are to cause the one or more processors to:
- track, through a first capacitive touch surface, a continuous touch event,
- during the continuous touch event, determine that a touch event location enters a first edge zone proximate a second capacitive touch surface, and
- while the touch event location is in the first edge zone, use a relaxed threshold for tracking the continuous touch event and detecting transition of the continuous touch event to the second capacitive touch surface,
- wherein using the relaxed threshold includes lowering a threshold for determining that capacitive sensor readings constitute a continued touch from a regular threshold to a lower threshold, so as to include a hover event as the continued touch.
