Abstract

The invention provides a cursor control device and system. The cursor control device comprises an image sensor, a processing unit, a selecting unit, a transmitting unit and at least one key. The image sensor obtains a plurality of image frames. The key outputs a trigger signal when pressed. The processing unit computes displacement according to the image frames, and outputs a control signal according to the trigger signal. The selecting unit selects one of at least two different cursor locking periods. The transmitting unit outputs the control signal and the displacement. The processing unit controls the transmitting unit to output zero displacement in the selected cursor locking period after receiving the trigger signal. The invention further provides a cursor control system.

Description

technical field [0001] The invention relates to a man-machine interface device, in particular to a cursor control device and system capable of adjusting the locking period of the cursor. Background technique [0002] Traditionally, image display devices, such as televisions, are used to display continuous images, so users can only use the buttons on the remote control device to unidirectionally control the output parameters of the image display device, such as sound, channel and brightness, etc. Features that interact with users. [0003] However, with the maturity of multimedia technology, smart TVs with various functions have become an important next-generation product. At the same time, in order to simplify the operation procedure of the remote control device, the cursor displayed on the display screen can be controlled by the remote control device. Perform multifunctional operations. [0004] For example refer to figure 1 As shown, it shows an interactive image system...
