  • Patent number: 10747995
    Abstract: There is provided a pupil tracking device including an active light source, an image sensor and a processing unit. The active light source emits light toward an eyeball alternatively in a first brightness value and a second brightness value. The image sensor captures a first brightness image corresponding to the first brightness value and a second brightness image corresponding to the second brightness value. The processing unit identifies a brightest region at corresponding positions of the first brightness image and the second brightness image as an active light image.
    Type: Grant

  • Publication number: 20150338228
    Abstract: A route planning method includes: displaying, by an output device, a map and an original route from a departure point to a destination through at least two intermediate points on the map, the intermediate points being selected from a plurality of points of interest that are pre-stored in a storage device; transmitting, by an input device, an input signal to the processor in response to a user selection of a priority one of the intermediate points; upon receipt of the input signal, planning, by a processor, a modified route passing sequentially through the departure point, the priority one of the intermediate points, the remaining one(s) of the intermediate points and the destination; and displaying, by the output device, the modified route on the map.
