Method for detecting users' pressing action and optical operating unit
A method for detecting users' pressing action is applied to an electronic apparatus which has at least an optical operating unit for an user to operate the electronic apparatus. The method includes the steps of detecting a deformation of a forcing object which forces the optical operating unit; and determining whether the user performs a pressing action according to a deformation degree of the forcing object. Further, an optical operating unit using the method is provided.
