Description

一种多屏拼接模式下多点触控方法、虚拟驱动及系统 Under a multi-screen mode, multi-touch method, system and virtual drive

技术领域 FIELD

[0001] 本发明属于屏幕触控技术领域,更具体地,涉及一种多屏拼接模式下多点触控方法、虚拟驱动及系统。 [0001] The present invention belongs to the technical field of the touch screen, and more particularly, to a multi-screen mode, the multi-touch method, and a system for the virtual drive.

背景技术 Background technique

[0002] 经济社会的发展带来了城市的进步,现代化的发展让我们的生活更加便利,为了看到更广阔的视野,视频显示单元在不断地升级,从LCD到LED,从显示器到投影机再到投影拼接、边缘融合。 [0002] economic and social development has brought progress in the city's modern development to make our lives easier, in order to see a broader perspective, the video display unit is constantly upgrading the projector from the LCD to LED, from the display to then projection splicing, edge blending. 特别是到现在流行的大尺寸触摸屏,越来越大的画面显示效果让多功能厅、会议室、表现手段更加丰富,表现内容更加生动。 Especially now popular large-size touch screen, increasing the screen display to make multi-purpose hall, meeting rooms, means of expression richer, more vivid performance of the content. 但是,我们发现,在实际使用过程中,使用者在大尺寸触控屏(例如电子白板)上操作,存在一些缺陷,一是身高限制,使用者无法自由的操作;二是使用者操作时会遮挡触控屏,会影响汇报工作中其余成员的观看,即不便于同步学习。 However, we found that in actual use, the user on a large touch screen (such as whiteboard) operation, there are some flaws, one height restrictions, the user can not operate freely; the second is when the user would operate occlusion touch screen, it will affect the rest of the members of the viewing reporting, that is not easy to synchronous learning. 三是超大屏幕价格昂贵,维修成本高。 Third, the large screen is expensive, high maintenance costs.

[0003] 为解决上述问题,提出一种新的屏幕构建方式即多屏拼接模式。 [0003] To solve the above problem, a new screen that is the way to build multi-screen mode. 多屏拼接模式指的是将多个显示屏拼接在一起,虚拟成一个超大显示屏,以实现更宽阔的桌面空间,最终整体的分辨率是多个显示屏分辨率的累加。 Multi-screen mode refers to multiple displays spliced ​​together into a virtual large screen, in order to achieve a broader desktop space, the final resolution of the overall screen resolution is more accumulation. 拼接模式下多屏显示,是将Windows桌面扩展到所有的显示设备上,这时Windows只有一个桌面,所有软件的界面扩展到新的显示桌面上,以实现更大范围的显示,这时的桌面相当于一个分辨率更大的显示器。 Under mosaic multi-screen display mode, the Windows desktop is extended to all of the display device, when only a Windows desktop, all the software interface extended to the new display desktop display in order to achieve greater range, then the Desktop It corresponds to the resolution of a larger display.

[0004] 现有多屏拼接模式下,一般是将多个屏的触控信号线直接连接到同一主机的USB口上,多屏触控信号被封装后将直接通过USB 口传送给主机操作系统。 [0004] Under the conventional multi-screen mode, the screen typically is a plurality of touch signal line is directly connected to the USB port on the same host, multiple touch-screen signal will be transmitted directly to the package through the USB port to the host operating system. 在通用驱动模式下,每个屏的触控信号都按照单屏的模式,直接被映射到拼接后的Windows桌面。 In general the drive mode, each of the panels are the touch signal according to the mode of single-screen, mapped directly to the stitched Windows desktop. 此时触控信息是单个屏的,但操作系统接收到的是却是针对拼接后的桌面的,从面造成混乱。 At this time, the touch screen of information is single, but the operating system is that it is received for the desktop after stitching, causing confusion from the surface. 因此只能对各屏先后分别触控操作,不能支持多个屏的同时触控操作,这很大程度上限制了老师与学生、学生与学生之间的互动学习,不管是Windows支持的扩展屏显示还是使用其他硬件设备都不能很好地解决这种问题。 Therefore, only for each screen has touch operation, respectively, can not support multiple simultaneous touch-screen operation, which greatly limits the interactive learning between teachers and students, students and students, whether it is supported by Windows screen expansion display or use other hardware devices can not be a good solution to this problem.
