You can use the following JS function:

function isTouchDevice() {
   var el = document.createElement('div');
   el.setAttribute('ongesturestart', 'return;'); // or try "ontouchstart"
   return typeof el.ongesturestart === "function";
}

Please note the above code only tests if the browser has support for touch, not the device.
