Wearable Mixed Reality System In Less Than 1 Pound

Daniel Thalmann, Frédéric Vexo, Achille Peternier

We have designed a wearable Mixed Reality (MR) framework which allows to real-time render game-like 3D scenes on see-through head-mounted displays (see through HMDs) and to localize the user position within aknown internet wireless area. Our equipment weig ...

Advanced virtual reality technologies for surveillance and security applications

Daniel Thalmann, Frédéric Vexo, Renaud Ott

We present a system that exploits advanced Virtual Reality technologies to create a surveillance and security system. Surveillance cameras are carried by a mini Blimp which is tele-operated using an innovative Virtual Reality interface with haptic feedback ...

Standardized Virtual Reality, are we there yet ?

Daniel Thalmann, Frédéric Vexo

Despite its history of several decades and impressive achievements, developing a VR application is still a complex task. Setting-up a Virtual Environment requires choosing a suitable combination of elements from a large amount of technologies, software fra ...

The Benefits of Third-Person Perspective in Virtual and Augmented Reality?

Daniel Thalmann, Frédéric Vexo, Patrick Salamin

Instead of the reality in which you can see your own limbs, in virtual reality simulations it is sometimes disturbing not to be able to see your own body. It seems to create an issue in the proprioperception of the user who does not completely feel integra ...

In Search for your own Virtual Individual

Daniel Thalmann, Frédéric Vexo, Alejandra Garcia Rojas Martinez

The use of inhabited Virtual Environments is continuously growing. People can embody a human-like avatar to participate inside these Virtual Environments or they can have personalized character acting as mediator; sometimes they can even customize it to so ...

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 ...

Multimodal authoring tool for populating a database of emotional reactive animations

Daniel Thalmann, Frédéric Vexo, Alejandra Garcia Rojas Martinez

We aim to create a model of emotional reactive virtual humans. This model will help to define realistic behavior for virtual characters based on emotions and events in the virtual environment to which they react. A large set of pre-recorded animations will ...

The “Caddie Paradigm”: a free-Locomotion Interface for Teleoperation

Daniel Thalmann, Frédéric Vexo

This paper presents the “caddie paradigm” a new interface for teleoperation of mobile robots. We present a prototype based on the use of a treadmill as a free-locomotion interface. The “caddie paradigm” allows for controlling a real robot by “pushing” its ...

Semantic Virtual Environments with Adaptive Multimodal Interfaces

Daniel Thalmann, Frédéric Vexo

We present a system for real-time configuration of multimodal interfaces to Virtual Environments (VE). The flexibility of our tool is supported by a semantics-based representation of VEs. Semantic descriptors are used to define interaction devices and virt ...

Semantics-based representation of virtual environments

Daniel Thalmann, Frédéric Vexo

In this paper we present an object representation based on the semantics and functionality of interactive digital items - virtual objects - within a virtual environment (VE). We consider every object participating in a VE application not only as a 3D shape ...

Bridging Geometry and Semantics for Object Manipulation and Grasping

Daniel Thalmann, Frédéric Vexo, Tolga Abaci

In this paper, we present our on-going work towards grasping in an object manipulation context. Our proposal is a novel method that combines a tubular feature classification algorithm, a hand grasp posture generation algorithm and an animation framework fo ...
