Abstract:
There is provided a mode switching method of a dual mode optical navigation device. The dual mode optical navigation device is configured to be operated on a working surface and has a first bottom surface and a second bottom surface having an included angle with the first bottom surface. The mode switching method includes: determining whether the first bottom surface or the second bottom surface contacts with the working surface; switching the dual mode optical navigation device to a first mode when identifying that the first bottom surface contacts with the working surface; and switching the dual mode optical navigation device to a second mode when identifying that the second bottom surface contacts with the working surface.

Claim (Index 14):
A dual mode optical navigation device, configured to operate in a first mode or a second mode on a working surface, the dual mode optical navigation device comprising:\n a first bottom surface having a first flat surface; a second bottom surface having a second flat surface arranged at an angle with respect to the first flat surface of the first bottom surface, wherein the first flat surface of the first bottom surface is configured to be contacted with the working surface in the first mode, and the second flat surface of the second bottom surface is configured to be contacted with the working surface in the second mode; a light source configured to illuminate the working surface through the first bottom surface; an image sensor configured to capture an image frame of the working surface through the first bottom surface; and a process unit configured to calculate an image feature of the image frame to accordingly enter the first mode or the second mode, wherein the same image sensor is configured to capture the image frame of the working surface through the first bottom surface in both the first mode and the second mode, and the first bottom surface and the second bottom surface are free of any actuator for generating a pressed signal.
