Abstract: A navigation apparatus and method are provided. The apparatus receives an input data and at least a piece of positioning information. The apparatus performs a semantic analysis on the input data to generate a plurality of pieces of semantic information. The apparatus selects at least one of the semantic information as a filtering condition. The apparatus compares the filtering condition with a plurality of semantic tags in the map data to determine whether the semantic tags have at least one first semantic tag that meets the filtering condition. When determining that the semantic tags have the at least one first semantic tag, the apparatus generates a comparison result, wherein the comparison result is related to an object corresponding to the at least one first semantic tag. The apparatus generates a navigation route according to the comparison result and the at least a piece of positioning information.

Abstract: A virtual mouse simulation method used in a virtual mouse driving apparatus is provided. The method has the following steps of: capturing a plurality of input images continuously; detecting a finger area from the plurality of input images; detecting a specific event of the finger area; and generating a corresponding virtual mouse control command according to the specific event.

Abstract: A video recommendation system is provided. The video recommendation system has: an interaction device configured to receive feedback information of a video from a user, wherein the videos are composed of a plurality of video segments; a feature calculating module configured to calculate object features of at least a first video segment corresponding to the feedback information in the plurality of video segments; and an analysis module configured to recommend at least one first recommended video segment to the user from the plurality of video segments according to the calculated object features and the feedback information.
