Output control method and device of gesture sensing equipment, and display control method and system

Abstract

The invention relates to an output control method and device of gesture sensing equipment, and a display control method and system. The output control method comprises the following steps of: obtaining a displacement variation of the current movement by using an inertial device; calculating a deviation amount of the displacement variation of the current movement and a displacement variation output in the former moment; respectively carrying out proportional operation, differential operation and integral operation on the deviation amount and adding an obtained corresponding first correction, an obtained corresponding second correction and an obtained corresponding third correction to be used as a displacement variation output in the current moment; and the output control device comprises an obtaining unit used for obtaining the displacement variation of the current movement, a deviation amount calculating unit used for calculating the deviation amount of the displacement amount, and a processing unit used for respectively carrying out proportional operation, differential operation and integral operation on the deviation amount and adding results to be used as the displacement variation output in the current moment. According to the invention, the deviation in the displacement variation output by the gesture sensing equipment can be eliminated.

Description

technical field [0001] The present invention relates to gesture sensing equipment and its application field, in particular to an output control method, display control method, device and system of gesture sensing equipment. Background technique [0002] Most of the control process of the traditional computer mouse pointer is realized by optical sensors or laser sensors. These sensors are based on the principle of physical optics and need to be operated on platforms such as desktops. However, in many occasions, such as in computer multimedia teaching, users want to manipulate the mouse pointer in the air or realize applications such as multimedia TV playback and web browsing by manipulating the mouse pointer in the air. The mouse controlled by the above sensor cannot meet the above requirements. So the space mouse came into being. [0003] The space mouse is an input device that operates the screen cursor (mouse pointer) like a traditional mouse, but does not need to be atta...

Problems solved by technology

[0005] The displacement change output by the attitude sensing device is reflected on the computer or TV screen and other display terminals to form the final displayed simulation path (motion trajectory). Taking the space mouse as an example, the output results of the existing technology have the following problems: When the mouse performs motion positioning, the user's hand shakes, and the handheld device moves slowly and quickly, etc., resulting in deviations between the motion trajectory reflected on the computer or TV screen and the actual motion positioning of the user.
