An Ontology of Virtual Humans: Incorporating Semantics into Human Shapes

Daniel Thalmann, Frédéric Vexo, Alejandra Garcia Rojas Martinez

Most of the efforts concerning graphical representations of humans (Virtual Humans) have been focused on synthesizing geometry for static or animated shapes. The next step is to consider a human body not only as a 3D shape, but as an active semantic entity ...

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 ...

Acquiring, structuring shapes and annotating them with semantics to improve design activities

Daniel Thalmann, Frédéric Vexo

Shapes incorporate geometry as well as semantics and can be defined in 2D, 3D or higher dimensions. Geometric models can be structured in such a way that they can provide a relevant framework to insert semantic information or view dependent information abo ...
