An optical navigation device for operation in a surface navigation mode and a free space navigation mode. The optical navigation device includes a microcontroller, a first navigation sensor, and a second navigation sensor. The first navigation sensor is coupled to the microcontroller, and the second navigation sensor is coupled to the first navigation sensor. The microcontroller processes a movement of the optical navigation device. The first navigation sensor generates a first navigation signal in a first navigation mode. The second navigation sensor generates a second navigation signal in a second navigation mode and sends the second navigation signal to the first navigation sensor. By implementing a navigation sensor to process signals from multiple navigation sensors, the cost and size of the optical navigation device can be controlled, and a small packaging design can be used.
