Problem with InteractionManager and Head Rotation

[Hobl1990]

Overview

I want to interact with an object with the help of the Interaction Manager. Therefore I used the following example: http://www.appzinside.com/2017/02/27/moving-holographic-objects-by-hand-using-the-hololens/

Expected Behavior

TryGetPosition(out handpos) returns coordinates of the hand. The "CursorWithFeedback" prefab will be mapped to this coordinates.

Actual Behavior

The mapping works great but when I go around an object use the gesture, it will be recognized but I can't see the mapped prefab. I attached two pictures. On both pictures the scene in the hololens emulator and the 3d view are mentioned. Furthermore the position of the hand is displayed in the debug log of visual studio. I used

The first picture shows that the gesture is in the recognition frame and also displayed in the scene.

The second picture shows the scene after a head rotation. The gesture is detected in the frame but doesn't show in the scene.

@Hobl1990, What version / branch of MRTK are you using? Thanks!

[Hobl1990]

@davidkline-ms, I use the Version from 28th December 2017.

Thanks for the update!

@Hobl1990,
We are having a difficult time reproducing your issue. Would you be able to post the contents of the script you are using in your example? This will enable us to test exactly what you are running.

Thanks!

@Hobl1990,
One other question, i noticed that you posted emulator screen shots. How are you rotating the head in the emulator (which controls, modifier keys, etc). That will help us better understand the issue.

Thanks!

Hi @davidkline-ms ,
I used this code for the interactionmanager events:

#region Interaction Source Detected Event, will be called when a registered gesture will be detected for the first time 
    private void InteractionManager_InteractionSourceDetected(InteractionSourceDetectedEventArgs obj)
    {
        if (obj.state.source.kind == InteractionSourceKind.Hand) //Check if the detected object is a hand
        {
            gesture_status.text = "Hand detected";
            ready.gameObject.SetActive(false); //Hide the Ready GameObject
            pressed.gameObject.SetActive(false); //Hide the Select GameObject
            ready.transform.SetParent(Camera.main.transform); //Set main camera as parent for the Ready GameObject
            pressed.transform.SetParent(Camera.main.transform); //Set main camera as parent for the Select GameObject
            Backup.orig_interact = false;

        }
    }
    #endregion

    #region Interaction Source Lost Event, will be called when the gestures are outside of the gesture frame
    private void InteractionManager_InteractionSourceLost(InteractionSourceLostEventArgs obj)
    {
        if (obj.state.source.kind == InteractionSourceKind.Hand) //Checks if the object is a hand
        {
            gesture_status.text = "Hand lost"; //Display the status in the textfield
            ready.gameObject.SetActive(false); //Hide the Ready GameObject
            pressed.gameObject.SetActive(false); //Hide the Select GameObject
            Backup.orig_interact = false;
            

           
        }
    }
    #endregion

private void InteractionManager_InteractionSourceUpdated(InteractionSourceUpdatedEventArgs obj)
    {
        if (obj.state.source.kind == InteractionSourceKind.Hand)    //Hand will be recognized
        {  
            if (obj.state.anyPressed) //If Select gesture is active
            {

              
                    //Assign the cursor GameObject depending on the recognized gesture
                    pressed.gameObject.SetActive(true);
                    ready.gameObject.SetActive(false);
                    obj.state.sourcePose.TryGetPosition(out position_hand); //Get the position of the hand
                   
                    
                   
                    //Move the GameObject for the select gesture 
                    pressed.transform.position = new Vector3(position_hand.x, position_hand.y, position_hand.z + 1);
            }

            else // If ready gesture is active
            {
                       
                pressed.gameObject.SetActive(false);
                ready.gameObject.SetActive(true);

                obj.state.sourcePose.TryGetPosition(out position_hand);


               ready.transform.position =  new Vector3(position_hand.x, position_hand.y, position_hand.z+1);

@davidkline-ms I used shift + one of the movements (W,A,S,D). Same result when I tested it on HoloLens
