Input apparatus for multi-layer on screen display and method of generating input signal for the same

摘要

An input apparatus for a multi-layer on-screen display and a method of generating an input signal for a multi-layer on-screen display. The input apparatus includes: an acceleration sensing unit for sensing an acceleration of a motion of the input apparatus; a processing unit for obtaining information including a motion depth and a motion pattern of the input apparatus using the sensed acceleration and determining a layer to be activated from the information; and a transmitter for generating a signal including the determined layer and outputting the signal to the multi-layer OSD.

1. A system for a multi-layer on-screen display (OSD), the system comprising:
a remote control device comprising:
an acceleration sensing unit which senses an acceleration of a motion of the remote control device using a 3-axis acceleration sensor;a processing unit which determines a motion depth and a motion pattern of the remote control device based on the acceleration sensed by the acceleration sensing unit, and determines a layer to be activated from the motion depth and the motion pattern; anda transmitter which generates a signal indicating the layer determined by the processing unit and outputs the signal to the multi-layer OSD, and a display unit which receives the signal from the transmitter and performs a corresponding multi-layer OSD function, wherein the motion depth is a distance the remote control device is moved along in each direction of 3 axes and the motion pattern is the direction the remote control device is moved along the axis, wherein the motion pattern includes at least one of a backward operation and a forward operation towards the display unit, wherein the multi-layer OSD is displayed on a digital television for performing menu selection and does not incorporate a hierarchical menu structure, and wherein the processing unit comprises: an analog-to-digital converter (ADC) which converts the acceleration sensed by the acceleration sensing unit into a digital acceleration value; a frame transformer which transforms the digital acceleration value in a body frame of the remote control device into a first acceleration value in a navigation frame; an operation signal extractor which determines whether the motion is intended by a user from the first acceleration value in the navigation frame and outputs a second acceleration value based on whether the motion is intended by the user; a motion information extractor which determines the motion depth from the second acceleration value output from the operation signal extractor and recognizes the motion pattern; and a layer determinator for determining the layer to be activated according to the motion depth and the motion pattern
