Abstract: A haptic feedback system is disposed on a device, including a fixed portion, a movable portion, a connecting assembly, and a driving assembly. The fixed portion fixedly connects the device. The movable portion is movable along a first mode direction and a second mode direction relative to the fixed portion. The movable portion is movably connected to the fixed portion via the connecting assembly. The driving assembly drives the movable portion to move relative to the fixed portion by a driving force, wherein a driving direction of the driving force is different from the first mode direction and the second mode direction.

Abstract: An optical system is provided, including a movable part, a fixed part, a first sensor, a second sensor, and a control unit, wherein an optical element is disposed on the movable part. The first and second sensors detect the movement of the movable part relative to the fixed part in a first dimension and a second dimension, and thus they respectively generate a first sensing value and a second sensing value. The control unit generates an error value according to the first sensing value and an error curve, and then calibrates the second sensing value according to the error value.
