Can you please take a look at this demo and let me know how I can detect whether the mousemove is toward Left or Right?

 $('.container').mousedown(function(){
    $(this).mousemove(function(){
      //if Moves Left { console.log("Moving Left"); }
      //if Moves Right {  console.log("Moving Right"); }
    });
});     
  $('.container').mouseup(function(){
    $(this).unbind("mousemove");
});      

.container {
    height:200px;
    width:200px;
    background-color:#1abc9c;
}

<script src=".1.1/jquery.min.js"></script>
<div class="container"></div>

Definitely one off the many solution:

$('.container').mousedown(function(e1){
    var mx = e1.pageX;//register the mouse down position

    $(this).mousemove(function(e2){

        if (e2.pageX > mx){ //right w.r.t mouse down position
            console.log("Moved Right");
        } else {
            console.log("Moved Left")
        }
    });
});     
  $('.container').mouseup(function(){
    $(this).unbind("mousemove");
});      

working code here

Hay this is quite easy just add this code inside you script tag and view on your console.

var bodyElement = document.querySelector("body");
bodyElement.addEventListener("mousemove", getMouseDirection, false);
 
var xDirection = "";
var yDirection = "";
 
var oldX = 0;
var oldY = 0;
 
function getMouseDirection(e) {
    //deal with the horizontal case
    if (oldX < e.pageX) {
        xDirection = "right";
    } else {
        xDirection = "left";
    }
 
    //deal with the vertical case
    if (oldY < e.pageY) {
        yDirection = "down";
    } else {
        yDirection = "up";
    }
 
    oldX = e.pageX;
    oldY = e.pageY;
 
    console.log(xDirection + " " + yDirection);
}

 $('.container').mousedown(function(e){
    var prevX = e.clientX;
    $(this).mousemove(function(e){
      
      if(e.clientX < prevX) { console.log("Moving Left"); }
      if(e.clientX > prevX) {  console.log("Moving Right"); }
      prevX = e.clientX;
    });
});     
  $('.container').mouseup(function(){
    $(this).unbind("mousemove");
});      

.container {
    height:200px;
    width:200px;
    background-color:#1abc9c;
}

<div class="container"></div>
