Toward Adaptive VR Simulators Combining Visual, Haptic, and Brain-Computer Interfaces
Found in: IEEE Computer Graphics and Applications
By Anatole Lecuyer,Laurent George,Maud Marchal
Issue Date:September 2013
pp. 18-23
The next generation of VR simulators could take into account a novel input: the user's mental state, as measured with electrodes and a brain-computer interface. One illustration of this promising path is a project that adapted a guidance system's force fee...
A Survey on Bimanual Haptic Interaction
Found in: IEEE Transactions on Haptics
By Anthony Talvas,Maud Marchal,Anatole Lecuyer
Issue Date:July 2014
pp. 1-1
When interacting with virtual objects through haptic devices, most of the time only one hand is involved. However, the increase of computational power, along with the decrease of device costs, allow more and more the use of dual haptic devices. The field w...
Design and evaluation of methods to prevent frame cancellation in real-time stereoscopic rendering
Found in: 3D User Interfaces
By Jerome Ardouin, Anatole Lecuyer, Maud Marchal, Eric Marchand
Issue Date:March 2011
pp. 95-98
Frame cancellation comes from the conflict between two depth cues: stereo disparity and occlusion with the screen border. When this conflict occurs, the user suffers from poor depth perception of the scene. It also leads to uncomfortable viewing and eyestr...
Joyman: A human-scale joystick for navigating in virtual worlds
Found in: 3D User Interfaces
By Maud Marchal, Julien Pettre, Anatole Lecuyer
Issue Date:March 2011
pp. 19-26
In this paper, we propose a novel interface called Joyman, designed for immersive locomotion in virtual environments. Whereas many previous interfaces preserve or stimulate the users proprioception, the Joyman aims at preserving equilibrioception in order ...
Six Degrees-of-Freedom Haptic Interaction with Fluids
Found in: IEEE Transactions on Visualization and Computer Graphics
By Gabriel Cirio,Maud Marchal,Sébastien Hillaire,Anatole Lécuyer
Issue Date:November 2011
pp. 1714-1727
We often interact with fluids in our daily life, either through tools such as when holding a glass of water or directly with our body when we swim or we wash our hands. Multimodal interactions with virtual fluids would greatly improve the simulations reali...
Can you stand on virtual grounds? A study on postural affordances in virtual reality
Found in: Virtual Reality Conference, IEEE
By Tony Regia-Corte,Maud Marchal,Anatole Lecuyer
Issue Date:March 2010
pp. 207-210
The concept of affordance, introduced by the psychologist James Gibson, can be defined as the functional utility of an object, a surface or an event. The purpose of this article was to evaluate the perception of affordances in virtual environments (VE). In...
Walking up and down in immersive virtual worlds: Novel interactive techniques based on visual feedback
Found in: 3D User Interfaces
By Maud Marchal, Anatole Lecuyer, Gabriel Cirio, Laurent Bonnet, Mathieu Emily
Issue Date:March 2010
pp. 19-26
We introduce novel interactive techniques to simulate the sensation of walking up and down in immersive virtual worlds based on visual feedback. Our method consists in modifying the motion of the virtual subjective camera while the user is really walking i...
Toward "Pseudo-Haptic Avatars": Modifying the Visual Animation of Self-Avatar Can Simulate the Perception of Weight Lifting
Found in: IEEE Transactions on Visualization and Computer Graphics
By David Antonio Gomez Jauregui,Ferran Argelaguet,Anne-Helene Olivier,Maud Marchal,Franck Multon,Anatole Lecuyer
Issue Date:April 2014
pp. 654-661
In this paper we study how the visual animation of a self-avatar can be artificially modified in real-time in order to generate different haptic perceptions. In our experimental setup, participants could watch their self-avatar in a virtual environment in ...
Fast Collision Detection for Fracturing Rigid Bodies
Found in: IEEE Transactions on Visualization and Computer Graphics
By Loeiz Glondu,Sara C. Schvartzman,Maud Marchal,Georges Dumont,Miguel A. Otaduy
Issue Date:January 2014
pp. 30-41
In complex scenes with many objects, collision detection plays a key role in the simulation performance. This is particularly true in fracture simulation for two main reasons. One is that fracture fragments tend to exhibit very intensive contact, and the o...
Can we use a brain-computer interface and manipulate a mouse at the same time?
Found in: Proceedings of the 19th ACM Symposium on Virtual Reality Software and Technology (VRST '13)
By Émilie Loup-Escande, Anatole Lécuyer, Colomban Busson, Jonathan Mercier-Ganady, Laurent George, Maud Marchal
Issue Date:October 2013
pp. 69-72
Brain-Computer Interfaces (BCI) introduce a novel way of interacting with real and virtual environments by directly exploiting cerebral activity. However in most setups using a BCI, the user is explicitly asked to remain as motionless as possible, since mu...
Elastic images: Perceiving local elasticity of images through a novel pseudo-haptic deformation effect
Found in: ACM Transactions on Applied Perception (TAP)
By Anatole Lécuyer, David Antonio Gómez Jáuregui, Ferran Argelaguet, Maud Marchal
Issue Date:August 2013
pp. 1-14
We introduce the Elastic Images, a novel pseudo-haptic feedback technique which enables the perception of the local elasticity of images without the need of any haptic device. The proposed approach focus on whether visual feedback is able to induce a sensa...
