Cursor control device and method

Abstract

The invention relates to a cursor control device which comprises a transmitter, receivers, a computation module and a conversion module. The transmitter is used for transmitting an ultra wide band radar signal; at least two receivers are provided, are distributed at the positions at equal distances to the transmitter and are used for receiving the ultra wide band radar signal; the computation module is used for computing position coordinates of a target object according to difference of time that different receivers receive the ultra wide band radar signal and the distance between the transmitter and the receivers; and the conversion module is used for changing and converting the position coordinates of the target object into a movement and click control signal of a mouse cursor. The invention also provides a corresponding cursor control method. Through the adoption of the cursor control device and the cursor control method, under the condition that people have lessons in a classroom or the distance between people and a machine is long, the transmitter and the receivers can be placed at proper positions so as to realize non-contact control on the movement and click operation of the mouse cursor; and the cursor control device not only cannot be abraded, but also is convenient to operate.

Description

【Technical field】 [0001] The present invention relates to the technical field of electronic product control, in particular to a control device and method for controlling a cursor similar to a mouse. 【Background technique】 [0002] The rapid development of computer technology, the mouse can be described as a major contribution. With the popularization of embedded computing and ubiquitous computing concepts, touch screen technology gradually replaces the mouse on mobile terminals and becomes the main human-computer interaction window. Both the mouse and the touch screen require direct contact with human hands, and at the same time, they are accompanied by mechanical wear and consumption to varying degrees, so that both of them become consumables and have to be replaced frequently, resulting in a waste of resources. At the same time, when teachers give lectures or lecture on slides, people need more interactive input methods, which cannot be achieved by ordinary mice and touch...

AI Technical Summary

Problems solved by technology

The equipment using the laser method is generally relatively large in size, and because the laser generator needs to consume a lot of energy, it is not economical to use in daily life.

[0003] The traditional mouse, touch screen and other devices have a short range of action, which cannot meet some medium-distance input requirements, such as teachers' lectures, slide presentations, etc.

The mouse needs to be in contact with the substrate, and the input is made through the friction between the rolling ball and the substrate or the photoelectricity according to the change of the substrate; will be useless

[0004] Traditional input devices mostly rely on mechanical pressing, friction, etc. to complete signal collection; these methods are inevitably accompanied by mechanical wear, which greatly shortens the service life of the product

At the same time, the traditional resistive touch screen often requires a large force input to obtain a more accurate positioning, which often leaves unsightly scratches on the surface of the touch screen, which not only affects the display effect, but also causes the inaccuracy of the input device itself
