Until now we did not know any mouse that can be used “in the air” and when we say no we mean the air be flying and use it (?), But need not be supported on any surface so that the sensors can follow the movements.
This is the Movea Gyration Air Mouse, a mouse that has been launched a few days ago promising enough, basically we can say that it can be used in the air without any surface and has a range of about 30 meters, especially for people who need to move around the room to make some kind of presentation.
Works with technology MotionSense to detect movements and comes with software GyroTools , which ideally complements to the subject of presentations. They are available for sale at Amazon.
