Multisensory learning cues using analytical collision detection between a needle and a tube

Etienne Burdet, Fei Wang

We are developing a Virtual Reality based training system for micromanipulation in collaboration with the National University Hospital in Singapore. While conventional approaches judge a virtual environment by its resemblance to the real environment, we us ...

Environmental Modeling with Fingerprint Sequences for Topological Global Localization

Roland Siegwart, Nicola Tomatis, Adriana Tapus, Pierre Lamon

In this paper a perception approach allowing for high distinctiveness is presented. The method works in accordance to the fingerprint concept. Such representation allows using a very flexible matching approach based on the minimum energy algorithm. The who ...

Towards interactive real-time crowd behavior simulation

Daniel Thalmann, Branislav Ulicny

While virtual crowds are becoming common in non-real-time applications, the real-time domain is still relatively unexplored. In this paper we discuss the challenges involved in creating such simulations, especially the need to efficiently manage variety. W ...

Defining behaviors for autonomous agents based on local perception and smart objects

Daniel Thalmann

An integrated framework is proposed in which local perception and close manipulation skills are used in conjunction with a high-level behavioral interface based on a "smart object" paradigm as support for virtual agents to perform autonomous tasks. In our ...

An informed environment for inhabited city simulation

In combination with the rapid technical improvements of computers, building large virtual scenes has become a popular field in computer graphics for education, films or games. Often, virtual humans populate scenes such as real reconstructed city, disappear ...

Towards autonomous, perceptive, and intelligent virtual actors

Daniel Thalmann

Explains methods to provide autonomous virtual humans with the skills necessary to perform stand-alone roles in films, games and interactive television. We present current research developments in the virtual life of autonomous synthetic actors. After a br ...

Evolution of neural control structures: Some experiments on mobile robots

Dario Floreano, Francesco Mondada

From perception to action and form action to perception, all elements of an autonomous agent are interdependent and need to be strongly coherent. The final behavior of the agent is the result of the global activity of this loop and every weakness of incohe ...

Perceptually tuned generation of grayscale fonts

Roger Hersch

A new approach to grayscale font generation improves on the fuzzy characters produced by existing methods by incorporating the expertise of type designers into rules for character-outline weight and phase control. The method we propose for synthesizing hig ...

Active Perception, Navigation, Homing, and Grasping: An autonomous Perspective

Dario Floreano, Francesco Mondada

Perception is needed for action, not for the pure sake of the construction of abstract representations, although it does not exclude the role of internal representations for mediating complex behaviors. We think that, for the purpose of building autonomous ...

Autonomous virtual humans in virtual worlds

Daniel Thalmann

Summary form only given. This paper discusses the problem of control and autonomy of synthetic actors. It first describes an animation approach where synthetic vision is used for navigation by a synthetic actor. The vision is the only channel of informatio ...
