Abstract: A signal sampling method, applied to a sensing system comprising a sensing matrix with a first sensing region and a second sensing region. The signal sampling method comprises: (a) applying a first single period sampling number to sample a sensing value of the first sensing region to generate a first sensing signal; and (b) applying a second single period sampling number to sample a sensing value of the second sensing region to generate a second sensing signal. The values of the first single period sampling number and the second single period sampling number are different. The selection for the single period sampling number is extended via sampling different sensing regions by different single period sampling numbers.

Abstract: An hybrid touch control method applied to an electronic apparatus comprising a touch interface. The hybrid touch control method comprises: (a) sensing if an object presses the touch interface to generate a pressure sensing signal; (b) sensing if the object touches the touch interface to generate a touch sensing signal; and (c) controlling the electronic apparatus according to the pressure sensing signal, but not according to the touch sensing signal. The step (c) can be replaced by: maintain or to stop an operation that the electronic apparatus is performing according to the pressure sensing signal if the touch sensing signal indicates the object is in a predetermined region of the touch interface. Via such method, the electronic apparatus can still be well controlled even if the touch is performed to a region that is not sensitive to touch.
