Method and apparatus for managing touch functionality in a repetitively flexible device
View Patent ↗A method, information handling system, and display assembly utilizes wherein a first touch panel indication is detected, and it is determined whether the first touch panel indication is from a defined bending area or from a defined non-bending area. When the first touch panel indication is from the defined bending area, it is determined if there is a second touch panel indication from an other touch sensor element adjacent to the first touch sensor element. When there is a simultaneous second touch panel indication, the touch location is interpolated based on the locations of the first and the other touch sensor elements. When there is a sequential second touch panel indication, the touch location is extrapolated based on locations of the first and the other touch sensor elements and a sequence of the first touch panel indication and the second touch panel indication.

when the second touch panel indication associated with the third touch sensor element is simultaneously received with the first touch panel indication, then interpolating the front cover touch location based on locations along the bendable spine associated with the first touch sensor element and the third touch sensor element; and
when the second touch panel indication associated with the third touch sensor element is sequentially received to the first touch panel indication, then extrapolating the front cover touch location based on the locations along the bendable spine of the first touch sensor element and the third touch sensor element and a sequence associated with the first touch panel indication and the second touch panel indication.
