摘要:
A remote pointing apparatus is provided. A light receiving unit may receive emitted light. A filtering unit may filter a received signal to a first frequency component, a second frequency component, a third frequency component, and a fourth frequency component. A calculation unit may compare amplitudes of the first frequency component and the second frequency component to calculate a first coordinate axis value of a cursor on a display unit, and compare amplitudes of the third frequency component and the fourth frequency component to calculate a second coordinate axis value of the cursor on the display unit.

A system and method for estimating a position and a direction using an infrared light are provided. The system may measure an intensity of an irradiation light irradiated by each light irradiator through each light receiver, and may estimate a position and a direction of a remote apparatus, based on the measured intensity, a light receiving directivity, and a light emitting directivity.
摘要:
An apparatus which adaptively adjusts a filtering coefficient according to motion data and a method thereof are provided. The apparatus sets a filtering coefficient according to motion data, and performs low pass filtering on the motion data according to the set filtering coefficient. Accordingly, a cutoff frequency may be adaptively changed according to moving velocity of a user and thus optimum motion data which are filtered irrespective of movement may be generated.
