Short Paper: Comparing Virtual Trajectories Made in Slalom UsingWalking-In-Place and Joystick Techniques
(The Eurographics Association, 2011)
In this paper we analyze and compare the trajectories made in a Virtual Environment with two different navigation techniques. The first is a standard joystick technique and the second is the Walking-In-Place (WIP) technique. ...
Ray-Traced Collision Detection: Interpenetration Control and Multi-GPU Performance
(The Eurographics Association, 2013)
We proposed in [LGA13] an iterative ray-traced collision detection algorithm (IRTCD) that exploits spatial and temporal coherency and proved to be computationally efficient but at the price of some geometrical approximations ...
From Observations to Collaborative Simulation: Application to Surgical Training
(The Eurographics Association, 2016)
In surgical training, Virtual Reality systems are mainly focused on technical surgical skills, leaving out procedural aspects. Our project aims at providing a novel approach to the use of Virtual Reality addressing this ...
A New Adaptive Data Distribution Model for Consistency Maintenance in Collaborative Virtual Environments
(The Eurographics Association, 2010)
Ensuring that all the users see the same state of a Collaborative Virtual Environment (CVE) at the same time is very important to provide effective collaboration between these users. Absolute consistency is nearly impossible ...
Short Paper: #SEVEN, a Sensor Effector Based Scenarios Model for Driving Collaborative Virtual Environment
(The Eurographics Association, 2014)
In this paper we present #SEVEN, a sensor effector model that enables the execution of complex scenarios for driving Virtual Reality applications. #SEVEN is based on an enhanced Petri net model which is able to describe ...
The Stretchable Arms for Collaborative Remote Guiding
(The Eurographics Association, 2015)
The help of a remote expert to guide an agent in performing a physical task can be advantageous in many ways: saving time and money by avoiding travel, and thus increasing the rate of intervention. In many situations, the ...
Roles in Collaborative Virtual Environments for Training
(The Eurographics Association, 2015)
In this paper we present a novel approach to role modelling for Collaborative Virtual Environments with an Action Oriented Scenario Engine. Our role model is able to take into account different data about the actions such ...
