有触摸屏，xp系统，代码：

方法一：

    class Win32
    {
        [StructLayout(LayoutKind.Sequential)]
        public struct POINT
        {
            public int X;
            public int Y;

            public POINT(int x, int y)
            {
                this.X = x;
                this.Y = y;
            }
        }

        [DllImport("user32.dll", CharSet = CharSet.Auto)]
        public static extern bool GetCursorPos(out POINT pt);
    }

    /// <summary>
    /// MainWindow.xaml 的交互逻辑
    /// </summary>
    public partial class MainWindow : Window
    {
        int x, y;
        DispatcherTimer timer = new DispatcherTimer();

        public MainWindow()
        {
            InitializeComponent();
            setButtonStyle();

            timer.Tick += new EventHandler(timer_Tick);
            timer.Interval = new TimeSpan(0, 0, 10); //10秒后开始运行
        }

        void timer_Tick(object sender, EventArgs e)
        {
            Win32.POINT pi = new Win32.POINT();
            Win32.GetCursorPos(out pi);

            int _x = pi.X;
            int _y = pi.Y;

            if ((x + 4 == _x) && (y + 3 == _y))
            {
                timer.IsEnabled = false;

                if (MessageBoxResult.Yes == MessageBox.Show("确定退出吗？", "友情提示", MessageBoxButton.YesNo))
                {
                    this.Close();
                }
            }
        }

        //鼠标左键按下时
        private void Window_MouseLeftButtonDown(object sender, MouseButtonEventArgs e)
        {
            //鼠标按下时获取当前鼠标坐标
            x = (int)(Mouse.GetPosition(e.Source as FrameworkElement).X);
            y = (int)(Mouse.GetPosition(e.Source as FrameworkElement).Y);

            timer.IsEnabled = true;
        }
        //鼠标右键按下时
        private void Window_MouseLeftButtonUp(object sender, MouseButtonEventArgs e)
        {
            x = -1;
            y = -1;
            timer.IsEnabled = false;
        }
   }

方法二：

    /// <summary>
    /// MainWindow.xaml 的交互逻辑
    /// </summary>
    public partial class MainWindow : Window
    {
        int x, y;
        DispatcherTimer timer = new DispatcherTimer();
        DispatcherTimer timer2 = new DispatcherTimer();
        DateTime start;

        public MainWindow()
        {
            InitializeComponent();
            setButtonStyle();

            timer.Tick += new EventHandler(timer_Tick);
            timer.Interval = new TimeSpan(0, 0, 1);
            timer.Start();

            timer2.Tick += new EventHandler(timer2_Tick);
            timer2.Interval = new TimeSpan(0, 0, 2);
            timer2.Start();
        }

        void timer_Tick(object sender, EventArgs e)
        {
            timer.Stop();
            x = (int)(Mouse.GetPosition(this).X);
            y = (int)(Mouse.GetPosition(this).Y);
        }

        bool ff = true;
        void timer2_Tick(object sender, EventArgs e)
        {
            int _x = (int)(Mouse.GetPosition(this).X);
            int _y = (int)(Mouse.GetPosition(this).Y);

            if ((x == _x) && (y == _y) && ff)
            {
                start = DateTime.Now;
                ff = false;
            }
            if (x != _x || y != _y)
            {
                x = _x;
                y = _y;
                start = DateTime.Now;
                ff = true;
            }

            TimeSpan ts = DateTime.Now.Subtract(start);

            //鼠标或键盘误动作3分钟后开始播放视频
            if (ts.Minutes >= 3)
            {
                //MessageBox.Show("x:" + x.ToString() + ";y:" + y.ToString() + "\n _x:" + _x.ToString() + ";_y=" + _y.ToString()+"\n"+ff.ToString().ToString() + " " + ts.Hours.ToString() + " " + ts.Minutes.ToString() + " " + ts.Seconds.ToString());
                //关闭所有子窗体
                WindowCollection windows = Application.Current.Windows;
                foreach(Window window in windows)
                {
                    string title = window.Title;
                    if(title != "MainWindow")
                    {
                        window.Close();
                    }
                }
            }

        }
