你看我给你的那个链接，这个是官方论坛里面给出的关于delta zero的回答，显然delta zero分成三部分：
Lens design （透镜设计）: The physical shape of the lens improves focusing of light on the tracking surface.
Illumination geometry （光线角度几何学）: The angle at which the LED light is directed at the tracking surface.
Data processing algorithms （数据处理算法）: The data collected by the sensor is processed onboard to accurately translate hand movement into on-screen cursor placement.
