The mouse movement speed detection-CodePudding

V software is used to collect the actual speed of the mouse, note: instead of the mouse on the computer interface movement speed hand controls the speed of the mouse

Elementary school thinking: the GetCursorPos (), call timer to determine a time period where the mouse moves to the distance/time=speed this time is the cycle of the timer can be 1 ms 10 ms

CSND: use DirectInput components GetDevice struct

Timer timer not estimate, level is very low, can't accurate trigger a 10 ms, so the accuracy of speed is impossible

Compared with the underlying way, is the only accurate, DirectInput can try

Is at the bottom of the way, is the only accurate, DirectInput can try

Who knows, let the landlord to give it a try, let's take the results of the bench, etc

The original poster is a new scholars, many places do not understand, bosses can be careful to speak, the best post code, thank you

CodePudding user response:

Use the camera to use the mouse hand clap to compare,

CodePudding user response:

Distance/time=speed, distance how to calculate?? Computer interface mouse movement distance? Hand to control the speed of the mouse!=computer interface mouse movement distance/time, maybe a little bit of mouse movement, the computer interface of the mouse ran a long distance,
