Is it a good idea to add an option to choose how to do pointer movements?
1 - place it directly under your finger
2 - move it with your finger like it is a touchpad
(1/2) - an extra option to increase the precision using a gyroscope (for example, this is a very useful option in linux deploy)
upd. Alot of players think that mobile port is not so user friendly. This option that I offering will solve this problem.
