| 摘要 |
An apparatus including a touch user interface device including a sensor array configured to sense spatial information associated with one or more contiguous regions of contact and a processing device in communication with the touch user interface device configured to discern a first contiguous region of contact corresponding to a first finger from the one or more contiguous regions of contact, determine a first spatial distribution profile of the first contiguous region at a first time, determine a second spatial distribution profile of the first contiguous region at a second time, analyze a shape variation of the second spatial distribution profile in comparison to the first spatial distribution profile to determine a rotational movement of the first finger, generate a control signal in response to the detected rotational movement.
