Problems solved by technology

The problem with these touch screen technologies is that there is no ability to track multiple points of contact, and the position is not reported correctly when multiple touch points land on positions horizontal and vertical to the grid lines
[0004] However, the above touch technologies are all applied to flat touch screens, and there is no touch technology suitable for spherical screens.

Abstract

The invention relates to a multi-touch device based on sphere display and a multi-touch method thereof. The device comprises a touch dome-screen, a projector, and an infrared LED. The device is characterized by being further provided with a dome-screen lens, a video camera with an infrared camera, a special filter and a computer. The touch dome-screen is prepared by the dome-screen materials through which the infrared projection can pass, the lower part of the touch dome-screen is provided with an opening, the infrared LED is arranged at the opening; the dome-screen lens is arranged in the middle of the opening and projects coloured lights from the projector to the touch dome-screen; the computer is respectively connected with the video camera and the projector and is used for respectively controlling the projector to project images to the touch dome-screen, the infrared camera of the video camera to collect images on the touch dome-screen and analyze and calculate the collected touch events on the touch dome-screen, and the projector to display the analyzed and calculated result.

Description

technical field [0001] The invention relates to a spherical touch screen technology, in particular to a spherical display-based multi-point touch device and a multi-point touch method realized by the device. Background technique [0002] At present, touch screens have been widely used in various electronic devices to control electronic devices to achieve various functions, especially in computer application systems, touch screens are often used to replace the input control functions of keyboards and mice. Simply click the prompt graphics on the display to realize the interaction between human and equipment. Usually, a touch screen includes a transparent touch panel that covers the visible area of ​​the display screen, a controller and corresponding driver software. The touch panel records touch events and sends touch signals to the controller. The controller processes these signals. Then the touch event and touch position data are handed over to the computer software to int...
