我正在写一个应用程序[net/wpf/c#],它应该测量用户在听到单词后点击(响应)的速度。它被称为听觉处理速度测试(PST),人类的平均速度大约为70-140ms。为了了解生成的事件的精确性,我写了以下内容。实时测量鼠标点击间隔
public partial class MainWindow : Window
{
System.Diagnostics.Stopwatch w = new System.Diagnostics.Stopwatch();
public MainWindow() { InitializeComponent(); }
private void textBlock1_PreviewMouseDown (object sender, MouseButtonEventArgs e)
{
e.Handled = true;
w.Stop();
System.Diagnostics.Debug.WriteLine(w.ElapsedMilliseconds);
w.Reset(); w.Start();
}
private void Grid_KeyDown (object sender, KeyEventArgs e)
{
e.Handled = true;
w.Stop();
System.Diagnostics.Debug.WriteLine(w.ElapsedMilliseconds);
w.Reset(); w.Start();
}
}
private void Application_Startup (object sender, StartupEventArgs e)
{
Process thisProc = Process.GetCurrentProcess();
thisProc.PriorityClass = ProcessPriorityClass.RealTime;
ProcessThreadCollection myThreads = thisProc.Threads;
foreach (ProcessThread pt in myThreads) {
pt.PriorityLevel = ThreadPriorityLevel.TimeCritical;
}
}
我可以点击最快的是100毫秒左右,如果保持压下键盘键再往下我坐下来的响应时间30毫秒。有什么办法可以让它变得更快吗? TIA
PS:我的keyboad重复间隔设置为最高。 – user109134 2010-11-18 01:42:39
