摘要
针对超高分辨率大幅面显示系统目前因缺少高效的人机交互设备导致应用受限问题,提出了一种基于多相机激光触点跟踪的交互方法。该方法通过在单个显示单元融合多个触点跟踪设备的交互信息,提高了交互精度;通过跨显示单元的触点空间变换实现了对大幅面显示系统的支持,提高了系统的扩展性。试验表明,该方法可应用于大幅面显示系统的人机交互设备。
Aimed at the problem of lacking an efficient human computer interaction （HCI） system for super high resolution large display, an interaction method based on multi-camera touch-point tracking is proposed. In this method, the touch-point tracking fusion method is applied to in- creasing the precision of interaction and the translational transform of touch-points is applied to providing the Iarge display interaction ability. The design is extensible for the modularized de- sign. Experimental results show that the method can be used in the HCI system for the large dis- play.
