“…Future work may involve studies of DOF coordination for multiple users, similar to previous research on two-handed interaction [33] [15], and experiments for comparing our approach to more recent work in bimanual interaction [32]. As additional future work we also foresee performing experiments with physically separated users.…”

Cooperative manipulation refers to the simultaneous manipulation of a virtual object by multiple users in an immersive virtual environment (VE). In this work, we present techniques for cooperative manipulation based on existing single-user techniques. We discuss methods of combining simultaneous user actions, based on the separation of degrees of freedom between two users, and the awareness tools used to provide the necessary knowledge of the partner activities during the cooperative interaction process. We also present a framework for supporting the development of cooperative manipulation techniques, which are based on rules for combining single user interaction techniques. Finally, we report an evaluation of cooperative manipulation scenarios, the results indicating that, in certain situations, cooperative manipulation is more efficient and usable than singleuser manipulation.

Abstract. Precision tasks in 3D like object manipulation or character animation call for new gestural interfaces that utilize many input degrees of freedom. We present MotionBender, a sensor-based interaction technique for post-editing the motion of e.g. the hands in character animation data. For the visualization of motion we use motion paths, often used for showing e.g. the movement of the hand through space over time, and allow the user to directly "bend" the 3D motion path with his/her hands and twist it into the right shape. In a comparative evaluation with a mouse-based interface we found that subjects using our technique were significantly faster. Moreover, with our technique, subject movement was more coordinated, i.e. movement was done in all three dimensions in parallel, and the participants preferred our technique in a postexperiment questionnaire. We also found a gender effect: male users both like the gesture interaction better and achieve better performance.

“…The task is a three dimensional positioning task based on the docking task introduced by Zhai [15] (Figure 1). Each experimental trial began after the previous target was successfully positioned, and ended with the successful positioning of the current target.…”

Figure 1: (i) Illustration of the Z -technique. The first finger (right hand in the example) is used for direct positioning in the camera plane while the second finger (left hand) is used for depth positioning in an indirect way. Backward-forward movements move the object farther or closer to the user. (ii and iii) Illustration of the multi-touch viewport technique. The first finger (left hand) is used for 2D positioning in the camera plane corresponding to the viewport (ii) while the second finger (right hand) is used to move the object along the third coordinate (iii). The gray line is used as visual feedback to represent the displacement allowed for the second finger. ABSTRACTMulti-touch displays represent a promising technology for the display and manipulation of 3D data. To fully exploit their capabilities, appropriate interaction techniques must be designed. In this paper, we explore the design of free 3D positioning techniques for multi-touch displays to exploit the additional degrees of freedom provided by this technology. Our contribution is two-fold: first we present an interaction technique to extend the standard four viewports technique found in commercial CAD applications, and second we introduce a technique designed to allow free 3D positioning with a single view of the scene. The two techniques were evaluated in a preliminary experiment. The first results incline us to conclude that the two techniques are equivalent in term of performance showing that the Z-technique provides a real alternative to the statu quo viewport technique.
