Cumulative Sensor in a Foldable Device

A foldable device comprising:

• a first housing portion;
• a second housing portion;
• a hinge structure joined to the first housing portion and the second housing portion to permit the foldable device to be folded along an axis between an open mode and a closed mode;
• a plurality of touch sensors disposed along one or more of the first housing portion or the second housing portion;
• a module implemented at least partially in hardware and configured to:
• receive touch input from one or more cumulative sensors on the foldable device, a cumulative sensor resulting, when said foldable device is folded along the axis into a closed mode, from a combination of individual touch sensors when the foldable device is in an open mode;
• determine whether the received touch input matches a cumulative pattern defined by a gesture;
• responsive to the received touch input matching the cumulative pattern, process the input to provide access to functionality associated with the gesture.

A method comprising:

• determining, on a foldable computing device, touch sensor physical proximity;
• responsive to the touch sensor physical proximity not being less than a threshold, determining that the foldable computing device is in an open mode and causing the foldable computing device to be operated in a single sensor mode;
• and
• responsive to the touch sensor physical proximity being less than the threshold, determining that the foldable computing device is in a closed mode and causing the foldable computing device to be operated in a cumulative sensor mode.
