发现抬起高度调节（Lift-Off Range）上面还有个表面校准（Surface Calibration）可以设置开关。看来光电光头不光是抬起高度么，不知道这个选项有什么用。测评里也没测（当然要测也会比较花工夫，找垫子啦、怎么量化数据啦），会不会有的表面没办法有效校准，就挑垫子了。
修正持保留态度，雷蛇联合飞利浦开发激光引擎的卖点就是无修正，没道理偷偷加上修正，就算要加也会在之前宣传修正是有用的吧……
官网下的电子版使用手册：
5. SURFACE CALIBRATION
a. On/Off When set to "On", the 4G Dual Sensor System will calibrate your mouse to the specific surface, optimizing it for fast and precise tracking. When set to "Off", your mouse will perform without the added benefit of surface calibration by the 4G Dual Sensor System. This is only necessary in certain circumstances such as when a surface is multicolored. Otherwise, the general recommendation is to keep the surface calibration setting to "On" permanently to get the best out of your mouse.
b. Lift-Off Range i. Auto - The mouse will automatically calibrate to your surface whenever the mouse is plugged into your system. ii. Custom - Increase or decrease the height where tracking is cut off as soon as the mouse is lifted from the surface.
意思是彩色表面不要开Surface Calibration？ |
