A method and apparatus for performing motion recognition using motion sensor fusion and an associated computer program product are provided, where the method is applied to an electronic device. The method includes the steps of: utilizing a plurality of motion sensors of the electronic device to obtain sensor data respectively corresponding to the plurality of motion sensors, the sensor data measured at a device coordinate system of the electronic device, wherein the plurality of motion sensors includes inertial motion sensors; and performing sensor fusion according to the sensor data by converting at least one portion of the sensor data and derivatives of the sensor data into converted data based on a global coordinate system of a user of the electronic device, to perform motion recognition based on the global coordinate system, in order to recognize the user's motion.

Method and apparatus for performing motion recognition using motion sensor fusion, and associated computer program product

An electronic apparatus including a plurality of sensors, an application processor, and a micro-processor is provided. The plurality of sensors is configured to generate at least one sensing signal. The application processor is configured to execute an application procedure according to a sensing-merged signal. The micro-processor is coupled between the plurality of sensors and the application processor, and is configured to generate the sensing-merged signal according to the at least one sensing signal. By utilizing the electronic apparatus, not only power can be saved, but also the elasticity for choosing sensor chip vendors can be improved.

Electronic apparatus capable of being waked up through detecting motions

A method of generating a geometric heading during positioning is provided. The method includes the following steps: estimating a current declination information of a current position according to a declination database, wherein the declination database gathers a magnetic map and a plurality of declination information corresponding to a difference between a magnetic north and a geometric north at all grid positions on the magnetic map; generating a predicted heading according to an angular velocity reading of a gyroscope and a magnetic heading reading of a magnetometer; and generating the geometric heading according to the current declination information of the current position and the predicted heading.

Method of generating geometric heading and positioning system using the same method

An operating method of a display device includes controlling a shift of a cursor of a user interface reference frame according to a shift of the pointing device with reference to an initial point in a 3D spatial reference frame; and updating a position of the initial point in the 3D spatial reference frame according to an updating signal. An advantage of the present invention is when the operating range is changed, reference coordinates utilized by the pointing device are appropriately adjusted, so as to lower the affect of offset, allowing the pointing device to be applied in different areas/directions without having the cursor displayed on the display device to incorrectly reflect shift of the pointing device.
