摘要
常见的自由立体显示技术通过视差形成立体视觉,但是存在不少缺点,例如产生眩晕,立体空间比例失真,缺少360°环视效果和触控功能。提出一种将光学多点触控技术和真三维显示技术结合的光学真三维触控系统。系统将红外LED和定向反射材料结合起来,形成定向反射空间,从而检测到手指在空间中的位置,最终在真三维系统中显示手指的轨迹。同时采用子像素的概念,将系统分辨率提升了28%。试验结果表明,在不需要佩戴任何传感器、环境光变化的条件下,在真三维显示系统中实现了触控轨迹的精确显示。
Autosterescopic display always forms a three-dimensional vision through parallax which has disadvantages,such as dizziness,distortion on the proportion of three-dimensional space,lacking of 360o view as well as touching functionality.A true three-dimension touch control system based on optical multi-touch and true three-dimension technique is proposed.The structure is a combination of infrared LED and directional reflector materials,which creates a directional reflector space.The position of the finger in the space can be detected and the tracks of the finger finally will be displayed on the true three-dimension display system.System resolution is increased by 28% using the concept of sub-pixel.The Demonstration of the experiment shows that the system could realize accurate display of touch tracks on the true three-dimension display system without any sensors and the changing of the ambient light.
