Two-handed haptic feedback in generic virtual environments

Since [years] we hear about Virtual Reality as a discipline that could potentially provide benefits to many applications. Basically, the principle of Virtual Reality consists in stimulating user senses in order to give the impression to be in another place ...

Organic shape modeling through haptic devices

Daniel Thalmann, Frédéric Vexo, Renaud Ott

This paper presents a sketching system for 3D organic shapes modeling and animation using virtual reality devices. On the hardware side, it is based on the Haptic Workstation™ which conveys force feedback on the user arms (upper body limbs), and a head mou ...

VR haptic interfaces for teleoperation: an evaluation study

Daniel Thalmann, Frédéric Vexo, Renaud Ott

We present the results of an evaluation study in the framework of user interfaces for teleoperation of vehicles. We developed a virtual cockpit with haptic feedback provided by a Haptic Workstation™. Four alternative teleoperation interfaces were implement ...

Improving user comfort in haptic virtual environments through gravity compensation

Daniel Thalmann, Frédéric Vexo, Renaud Ott

Our experience with a Haptic Workstation™ has shown that this device is uncomfortable to use during long sessions. The main reason is the uncomfortable posture of the arms, which must be kept outstretched horizontally while supporting the weight of an exos ...

Mediators: virtual haptic interfaces for tele-operated robots

Daniel Thalmann, Frédéric Vexo, Renaud Ott

This paper develops the concept of mediators: virtual interfaces with haptic feedback for teleoperation. Our approach is to replace physical operator interfaces by fully parameterizable adaptive virtual interfaces. Mediators open new possibilities for mult ...
