A Robust Finger Tracking Method for Multimodal Wearable Computer Interfacing

Ali H. Sayed

Mobile wearable computers are intended to provide users with real-time access to information in a natural and unobtrusive manner. Computing and sensing in these devices must be reliable, easy to interact with, transparent, and configured to support differe ...

Advanced Mixed Reality Technologies for Surveillance and Risk Prevention Applications

Daniel Thalmann, Patrick Salamin, Frédéric Vexo, Renaud Ott

We present a system that exploits advanced Mixed and Virtual Reality technologies to create a surveillance and security system that could be also extended to define emergency prevention plans in crowdy environments. Surveillance cameras are carried by a mi ...

An all-in-one solution to geometric and photometric calibration

Pascal Fua, Vincent Lepetit, Julien Pilet, Pascal Lagger, Andreas Geiger

We propose a fully automated approach to calibrating multiple cameras whose fields of view may not all overlap. Our technique only requires waving an arbitrary textured planar pattern in front of the cameras, which is the only manual intervention that is r ...

Sensing reality and communicating bits: A dangerous liaison

Martin Vetterli, Michael Christoph Gastpar, Pier Luigi Dragotti

The successful design of sensor network architectures depends crucially on the structure of the sampling, observation, and communication processes. One of the most fundamental questions concerns the sufficiency of discrete approximations in time, space, an ...

Hybrid Tracking for Augmented Reality

Touradj Ebrahimi

Accurate registration between real and virtual objects is critical for Augmented Reality (AR) applications. State of the art shows that no tracking device is individually adequate. We present a data fusion framework that combines orientation measurements o ...

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 ...

Two-Handed Gesture Recognition

Sébastien Marcel, Agnès Just

Nowadays, computer interaction is mostly done using dedicated devices. But gestures are an easy mean of expression between humans that could be used to communicate with computers in a more natural manner. Most of the current research on hand gesture recogn ...

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 ...

Mobile Tele-echography: User Interface Design

Nikolaos Thomos

Ultrasound imaging allows the evaluation of the degree of emergency of a patient. However, in several occasions a well trained sonographer is unavailable to perform such echography. To cope with this issue, the OTELO project aims to develop a fully integra ...

Robust Feature Point Extraction and Tracking for Augmented Reality

Touradj Ebrahimi

For augmented reality applications, accurate estimation of the camera pose is required. An existing video-based markerless tracking system, developed at the ITS, presents several weaknesses towards this goal. In order to improve the video tracker, several ...
