1. Combining the strengths of UMIST and The Victoria University of Manchester Evaluation of Different Vibration Visualization Modes for Line Tracking Yuan Wang Supervisor: W.T. Hewitt Advisor: M.J. Turner Manchester Visualization Centre University of Manchester

2. Combining the strengths of UMIST and The Victoria University of Manchester 2 Haptic Sensation and Devices  Haptic Sensation –Vibrotactile Sensation: vibration, friction, texture … –Kinesthetic Feedback: force, torque, posture, orientation …  Haptic Devices –Tactile feedback devices: –Force feedback devices:

3. Combining the strengths of UMIST and The Victoria University of Manchester 3 Haptic Visualization Overview  The Primary Motivation of Haptic Visualization –To support graphic visualization cooperatively or complementarily.  The Reference Model of Haptic Visualization

4. Combining the strengths of UMIST and The Victoria University of Manchester 4 Line Based Mapping in Haptic Visualization  Line Based Mapping –Implicit Line: relative drag approach (Reimersdahl et al. 2003), magnetic Lorentz force or vortex vorticity simulation (Lawrence et al. 2002) … –Explicit Line: snap-to-grid force mapping with weighting function (Fritz et al. 1996), friction mapping along v-shaped grooves (Yu et al. 2001) …

5. Combining the strengths of UMIST and The Victoria University of Manchester 5 Mapping Foundation – Vibration Magnitude Model  Vibration Magnitude Model –Amplitude (0.01 – 0.5 N): magnitude estimation –Frequency (20 – 200 Hz): intramodal matching –Magnitude: 0.01 – 1000 –B-Spline Surface Fitting  Model Features –Peaks and valleys  Vibration Mapping Table –Extract any curve on surface
