+# Touch Input Module
+
+**Note: TouchInputModule is obsolete. Touch input is now handled in [StandaloneInputModule](script-StandaloneInputModule.md).**
+
+This module is designed to work with touch devices. It sends pointer events for touching and dragging in response to user input. The module supports multitouch.
+
+The module uses the scene configured Raycasters to calculate what element is currently being touched over. A raycast is issued for each current touch.
+

+## Details
+
+The flow for the module is as follows:
+
+- For each touch event
+    - If it is a new press
+        - Send PointerEnter event (sent to every object up the hierarchy that can handle it)
+        - Send PointerPress event
+        - Cache the drag handler (first element in the hierarchy that can handle it)
+        - Send BeginDrag event to the drag handler
+        - Set the 'Pressed' object as Selected in the event system
+    - If this is a continuing press
+        - Process movement
+        - Send DragEvent to the cached drag handler
+        - Handle PointerEnter and PointerExit events if touch moves between objects
+    - If this is a release
+        - Send PointerUp event to the object that received the PointerPress
+        - If the current hover object is the same as the PointerPress object send a PointerClick event
+        - Send a Drop event if there was a drag handler cached
+        - Send a EndDrag event to the cached drag handler
