Text input method and system for remote control

Abstract

A character input method of a remote-controller is provided. The method comprises steps of: receiving a remote-controller instruction; decoding a remote-controller instruction; executing a character search operation in a character library according to the decoded remote-controller instruction; displaying a character input method virtual interface and a corresponding character on a screen according to the character search operation; sensing movement of the remote-controller; calculating a speed v1 at which a focal point corresponding to the remote-controller on a virtual keyboard moves; judging whether the speed v1 at which the focal point moves is greater than a preset speed v; if the speed v1 is greater than the preset speed v, the remote-controller focal point automatically moves to a character that is marked and is in a distance smaller than or equal to d; and inputting a character at which the remote-controller focal point is located. The present invention further provides a remote-controller system applying the character input method. The character input method and system of remote-controller may facilitate a user to input a character on a television.

Description

technical field [0001] The invention relates to the technical field of digital television, in particular to a character input method and system for a remote controller. Background technique [0002] With the development of digital TV and the promotion and popularization of two-way services, users pay more and more attention to the interactive method of inputting text on TV. Since the function keys of the TV remote control are mainly numeric keys, each numeric key must be mapped to a different component of the character text if you want to input characters. Traditional remote controls need to use the direction keys of the remote control to input characters on the TV. To control, it may be necessary to press many buttons to select a character, which greatly affects the user's experience and interaction in TV services. Contents of the invention [0003] In view of the above, it is necessary to provide a text input method for the remote controller, which can facilitate the us...
