Approches directes et planifiées de l'interaction 3D sur terminaux mobiles

Abstract : Mobile devices, such as phones, PDAs or GPS, are getting more and more powerful. They are now able to compute and to display 3D scenes in real time.
However, mobile devices' ergonomics and technical limitations may make 3D interaction hard to achieve efficiently. In particular, 3D interaction techniques developed for desktop computers may be affected by the lack of mouse.

In this thesis, we will study mobile devices' constraints and specificities, and their influences on 3D interaction tasks. The first part of this thesis will be an introduction to the domains addressed in this thesis. We will define the term mobile device'' and analyze their technical and ergonomic specificities. We will also define some 3D geometry and 3D interaction basis.

In the second part of the thesis, we will talk about 3D interaction with direct control, which is used in many 3D applications, where the user's actions induce modifications into the 3D environment in real time. After presenting the related works, we will introduce a 3D inspection technique we have developed. This technique uses depth and contours information in order to compute camera movements adapted to the current context. The following of this second part will be dedicated to a study about benefits of using two fingers on a multitouch screen.

The third part of this thesis is dedicated to planned 3D interaction''. This kind of control is more adapted to the mobile devices' constraints and offers a higher level of interaction than direct control. We will define and analyze planned 3D interaction in this part. We will then present our contributions~: a key based 3D navigation technique, and a 3D camera positioning technique based on some gestures which allows both expert and novice users to easily specify a point of view.
