Chloe@University: An indoor, HMD-based mobile mixed reality guide

Daniel Thalmann, Xavier Righetti, Achille Peternier, Mathieu Hopmann

This paper describes an indoors, mobile mixed reality guide system: Chloe@University. With a see-through head-mounted display (HMD) connected to a hidden small computing device, Chloe@University provides users with an efficient way of guiding in a building ...

Pedestrian detection by range imaging

Heinz Hügli

Remote detection by camera offers a versatile means for recording people activities. Relying principally on changes in video images, the method tends to fail in presence of shadows and illumination changes. This paper explores a possible remedy to these pr ...

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

Daniel Thalmann, Patrick Salamin, Frédéric Vexo

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 ...

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 ...

Tracking and User Interface for Mixed Reality

Touradj Ebrahimi, Yousri Abdeljaoued

This chapter introduces the field of Mixed Reality that merges the real and virtual worlds seamlessly. To develop a Mixed Reality system, two fundamental problems should be addressed: tracking and user interface. Tracking in Mixed Reality is defined as the ...

MPEG-7 CAMERA

Touradj Ebrahimi, Yousri Abdeljaoued, Oscar Divorra Escoda

MPEG-7 camera extends the capabilities of conventional cameras by analyzing its scene in order to generate a contentbased description according to the recently approved MPEG- 7 standard. This gives to the camera a large variety of current and potential app ...

Augmented reality for real and virtual humans

Daniel Thalmann, Pascal Fua, Michal Ponder

Current virtual reality technologies provide many ways to interact with virtual humans. Most of those techniques, however, are limited to synthetic elements and require cumbersome sensors. We have combined a real-time simulation and rendering platform with ...

NEW DEVELOPMENT IN CAMERA CALIBRATION: CALIBRATING A PAIR OF MOBILE CAMERAS

Pearl Pu Faltings

A new method of camera calibration is proposed for active visual sensing for use in three-dimensional (3D) scene analysis. The method permits calibration of a mobile camera as a function of the position and orientation of the camera. The algorithm for iden ...

ANALYTICAL IDENTIFICATION OF THE CALIBRATION MATRICES USING THE TWO PLANE MODEL

Pearl Pu Faltings

A new method of camera calibration is proposed for active visual sensing for use in 3D scene analysis. The method, based on a variation of the two plane camera model, permits the calibration of a mobile camera as a function of the position and orientation ...
