  1. INRIA advancement reportA. Lécuyer, G. Cirio, L. Terziman, M. Marchal (INRIA) NIW Project, Udine, 23-24 February 2011

  2. Outline • Walking device (M. Marchal) • JoyMan : a human-scale joystick for NIW • Ground rendering (G. Cirio) • Haptic liquids (liquid grounds) • Multi-state haptics (multi-state grounds = deformable, solid, fluid) • Vibratory rendering of liquid grounds • Pseudo-haptic feedback (A. Lécuyer) • New effect for material properties • « King-Kong » effect • Interactive techniques (L. Terziman) • Shake-your-head : comparison with joystick • Multi-sensory shake-your-head : visual (king-kong effect), tactile, audio

  3. « JoyMan » : a Human-Scale Joystick M. Marchal, J. Pettre, A. Lécuyer, “Joyman: a Human-Scale Joystick for Navigating in Virtual Worlds”, IEEE International Symposium on 3D User Interfaces (IEEE 3DUI), Singapore, 2011 • « Human joystick » : navigation based on body orientation • (Marchal et al., IEEE 3DUI 2011) • (Patent, 2011)

  4. 6DoF Haptic Interaction with Fluids • A novel approach for haptic rendering of fluids • 6 DOF physically-based solid-fluid haptic interaction • A generic system: variable viscosity, arbitrary-shaped objects, multiple haptic coupling • G. Cirio, M. Marchal, S. Hillaire, A. Lécuyer, “Six Degrees-of-Freedom Haptic Interaction with Fluids”, IEEE Transactions on Visualization and Computer Graphics, In Press. • Presentation at IEEE Virtual Reality, Singapore, March 2011

  5. 6DoF Haptic Interaction with Multiple States of Matter • A single model allowing to interact with: • Fluids (Navier-Stokes) • Deformable bodies (continuum mechanics) • Rigid bodies (rigid body dynamics) • A single haptic rendering technique • The first multistate haptic rendering technique G. Cirio, M. Marchal, A. Le Gentil, A. Lécuyer, “Tap, Squeeze and Stir the Virtual World: Touching the Different States of Matter Through 6DoF Haptic Interaction”, IEEE Virtual Reality 2011 G. Cirio, M. Marchal, A. Lécuyer, “Assessing the 6DoF Haptic Rendering of Multi-State Simulations with Fluid, Deformable and Rigid Media”, Submitted to World Haptics 2011

  6. Vibrotactile Rendering of Fluids • Vibrotactile rendering of foot-fluid interaction • Model based on 3 components • Harmonic Bubbles • Main Cavity Oscillation • Initial Impact • Future work : • Paper for IEEE ToH • Further evaluations? >> McGill tiles, UPMC shoes • Acoustic rendering with Verona?

  7. Pseudo-haptic feedback T. Hachisu, G. Cirio, M. Marchal, A. Lécuyer, H. Kajimoto, « Pseudo-Haptic Feedback Augmented with Visual and Tactile Vibrations » , International Symposium on VR Innovation (ISVRI), 2011 • Simulation of material property: wood, metal, foam, etc • Novel effect based on visual vibration • Inspired by Force transients and event-based haptics • Seems very efficient !

  8. « King-Kong » effect? • Simulation of feet-ground contacts with visual oscillations • Inspired by movie effect • >> Oscillating motion of the virtual camera • Simulation of ground properties? • To be tested with Shake-Your-Head..

  9. Walking-in-Place and« Shake-Your-Head » • Walking-in-Place • Novel technique based on head movements • Sitting or Standing • Walk+Turn+Jump+Crawl • Evaluation : fast learning, high appreciation

  10. Implementation • L. Terziman, M. Marchal, M. Emily, F. Multon, B. Arnaldi, A. Lécuyer, “Shake-Your-Head: Revisiting Walking-In-Place for Desktop Virtual Reality”, ACM Symposium on Virtual Reality Software and Technology, Hong-Kong, China, 2010

  11. Shake-your-head : comparison with joystick • Joystick trajectories: • « Shake-Your-Head » (SYH) trajectories:

  12. Shake-your-head : comparison with joystick • Spatial analysis • Macroscopic: • Shape of the trajectories • Distance to the shortest path • Mean trajectories • Microscopic: • Curvature • Temporal analysis • Speed • Smoothness

  13. Multi-sensory shake-your-head • Visual • Audio • Vibration
