measurement - Sensors to detect and measure movement


I would like to know which sensors should I use in order to get measurement of a movement of my device (slow speed movement on a 2D plane, in cm or mm if possible). The goal is to find out if the user has moved the device from a starting point and to calculate the distance between the two points.


EDIT:


The plane will be 2.0m x 0.5m. It will be a device held by a person that will begin the "measurement" at the intersection of the diagonals of the plane. The user can lift the device. I can't tell you exact the speed right now - just a slow hand movement (but the speed will not be constant).


I would appreciate any advice on a device that could rotate; But in this case I am asking for a non-rotating device (there will be single point to track). There are no cost restrictions, the smaller the device, the better.

arduino - Can I use TI's cc2541 BLE as micro controller to perform operations/ processing instead of ATmega328P AU to save cost?

I am using arduino pro mini (which contains Atmega328p AU ) along with cc2541(HM-10) to process and transfer data over BLE to smartphone. I...
