Leap Motion is a virtual reality controller which allows users to interact with the virtual objects using their bare hands. However, the controller only allows the detection of hands up to 60cm from the sensor, which means that users cannot interact with virtual objects outside the same range in the virtual space. In this paper, we propose a new interaction method to overcome the limitation of the manipulation range. The movement of virtual hands in the virtual space is accelerated by the velocity of the hand movement and the range of the reachable virtual space is expended to the current view of the virtual space. Experimental results show that users can manipulate long-distance objects in a coherent and convenient way.
