I want to change position of modelitem to move when i click on hand movemenet

Hi @Nithin ,

I think to achieve such task could be possible but it  will be at least  very difficult because of the following reasons:

1.) we will get 2d canvas coordinates.

Let consider the mouse move event which works in preview. When you use some code like this:

 document.addEventListener('mousemove', function(event) { 
//this will work 1:1 also for 'click' event
 console.log("mousemove() 1 called"); console.warn(event);
 $scope.lastClick = { x: event.pageX, y: event.pageY};
 ///////////////////////////////////////
 // .fromTemplate() method
 var customEvent = {
 	target: {
 		getBoundingClientRect:function () {
 		return {
 			'left' :$scope.lastClick.x,
 			'top' :$scope.lastClick.y,
 			'width' :1,
 			'height':1,
 'title' : 'My Popup Dialog-'
 		 	};
 		}
 	}
 	}; 
 
 
var template = '<ion-popover-view><ion-header-bar> <h2 class="title">MOVE TEST</h2> </ion-header-bar> <ion-content><h1>' +
 "<p> X= "+ event.pageX + "</p>"+
 			 "<p> Y= "+ event.pageY + "</p>" +
 			 "<p>maxX="+window.innerWidth+ "</p>" +
 "<p>maxY="+window.innerHeight+"</p>" +
 
 			 '</h1></ion-content></ion-popover-view>';
 	var popover = $ionicPopover.fromTemplate(template, {scope: $scope});
 	
 
popover.show(customEvent);
 		var my_closeFunc = function(popover) {
 
 		var thePopover = popover;
//some print in the console
 console.info("thePopover");console.warn(thePopover)
 		return function() { thePopover.remove();
 }
 													}
 
 
 $timeout(my_closeFunc(popover), 500);// will close the popoever after 0.5 sec
 	$scope.$apply(); 
});

So now we need to calculated 3d model coordinates of the model item - so need to translate the 2d coordinate in 3d coordinates and then set the deltaX,YandZ to the current coordinates.

The first problem is how to translate the 2d X,Y click or move coordinate to the 3d. In generally is this possible. We have the eye coordinates given by tml3dRenderer.SetupTrackingEventsCommand - callback:

tml3dRenderer.setupTrackingEventsCommand (function(target,eyepos,eyedir,eyeup) {
 var args = {
 targetName: target,
 position : eyepos,
 gaze : eyedir,
 up : eyeup };
 $scope.$emit("rray-tracking", args);
 
 
 }) 
rootScope.$on('rray-tracking', function( tracker,fargs ) { 
 
 
 console.warn(fargs);
 //console.warn(fargs.position)
 
 $scope.app.params['eyepos'] ="eyepos=("+fargs.position[0].toFixed(2)+","+fargs.position[1].toFixed(2)+","+fargs.position[2].toFixed(2)+")";
 $scope.app.params['eyedir'] ="eyedir=("+fargs.gaze[0].toFixed(2)+","+fargs.gaze[1].toFixed(2)+","+fargs.gaze[2].toFixed(2)+")";
 $scope.app.params['eyeup' ] ="eyeup =("+fargs.up[0].toFixed(2)+","+ fargs.up[1].toFixed(2)+","+fargs.up[2].toFixed(2)+")";
 
 $scope.$applyAsync();
});

So means having the eye coordinates the max min X,Y 2d Canvas coordinates we can calculated the back transformation from 2d to 3d in X,Y,Z model space coordinates

The eye coordinates /vectors has as origin the middle of the 2d screen.

2.) a second issue is the problem of the particular end device interpretation of typical windows events like mousemove or click. The question is what is the interpretation on android device , on HoloLens or on IOS. This should be further tested
