  Teleoperation of Unmanned Aerial Vehicles (UAVs) has recently become an
noteworthly research topic in the field of human robot interaction. Each year,
a variety of devices is being studied to design adapted interface for diverse
purpose such as view taking, search and rescue operation or suveillance. New
interfaces have to be precise, simple and intuitive even for complex path
planning. Moreover, when teleoperation involves long distance control, user
needs to get proper feedbacks and avoid motion sickness. In order to overcome
all these challenges, a new interaction metaphor named DrEAM (Drone Exocentric
Advanced Metaphor) was designed. User can see the UAV he is controlling in a
virtual environment mapped to the real world. He can interact with it as a
simple object in a classical virtual world. An experiment was lead in order to
evaluate the perfomances of this metaphor, comparing performance of novice user
using either a direct-view joystick control or using DrEAM.
