使用Myo臂带调用姿势触发事件 [英] Calling the pose triggered event using Myo arm band

问题描述

我正在使用Myo臂带在WPF中开发一个项目，到目前为止，该臂带可以识别设备已连接并更新文本框的信息，但是当我设置事件处理程序以识别姿势是否触发事件时

I'm developing a project in WPF using a Myo arm band which works so far in recognizing the device has connected and updates info to the textbox, but when I set up the event handler for recognizing if a pose is triggered the event never fires.

我通过使用设备摆姿势并握住它们来调试此问题，还在此行上设置了一个断点 pose.Triggered + = Pose_Triggered; 和姿势触发事件的开始。

I debugged this by making poses with the device and holding them, also I set a break point on this line pose.Triggered += Pose_Triggered; and the start of the pose triggered event.

断点在第一行触发，但不触发实际事件的断点 private void Pose_Triggered（object sender，PoseEventArgs e）

The break point triggers on the first line where the but it doesn't trigger the breakpoint on the actual event private void Pose_Triggered(object sender, PoseEventArgs e)

这是C＃包装程序正在为该项目使用： https://github.com/tayfuzun/MyoSharp

有人知道活动姿势时为何不触发事件吗？

Does anyone know why the event doesn't trigger although the poses are being made?

pose_triggered 被调用并发生以下事件：

This is the method where pose_triggered is called and the event:

// listen for when the Myo connects
                hub.MyoConnected += (sender, e) =>
                {

                    this.Dispatcher.Invoke((Action)(() =>
                    {
                        statusTbx.Text = "Myo has connected! " + e.Myo.Handle;
                        e.Myo.Vibrate(VibrationType.Short);

                        // unlock the Myo so that it doesn't keep locking between our poses
                        e.Myo.Unlock(UnlockType.Hold);

                        // setup for the pose we want to watch for
                        var pose = HeldPose.Create(e.Myo, Pose.Fist);


                        pose.Triggered += Pose_Triggered;
                        e.Myo.OrientationDataAcquired += Myo_OrientationDataAcquired;



                    }));

                };

触发事件的代码：

private void Pose_Triggered(object sender, PoseEventArgs e)
        {
            App.Current.Dispatcher.Invoke((Action)(() =>
            {
                //need to measure abduction of arm from 0 to 180 degrees.
                poseStatusTbx.Text = "{0} arm Myo holding pose {1}" + e.Myo.Arm + e.Myo.Pose;

                pitch = pitchCentre;

            }));    
        }

推荐答案

我比较了来自GitHub的示例代码和您的。您忘了叫 pose.Start（）吗？

I compare the sample code from GitHub and your. Did you forget to call pose.Start()?

var pose = HeldPose.Create(e.Myo, Pose.Fist);
pose.Interval = TimeSpan.FromSeconds(0.5); 
pose.Start(); //this???
pose.Triggered += Pose_Triggered;
