Abstract
An optical navigation device for controlling an operation of a pointer on a display apparatus is provided, the optical navigation device includes a device body, a substrate, a light source, an image sensor, and a processing module. The light source, the image sensor, and the processing module are respectively disposed on the substrate. The device body has a housing with an accommodating space formed therein. The substrate is arranged in the accommodating space of the housing. The light source operatively generates a light illuminating a navigation surface of the optical navigation device through the opening of the housing. The image sensor is oriented at a preset angle with respect to a long axis of device body and is configured for capturing images of the navigation surface. The processing module generates a displacement information of the optical navigation device relative to the navigation surface according to the images captured.
