  1. 2010 Summer HVR Lab workshop- NRL 2nd Year - 2010. 8. 4 Hong, Kyungpyo

  2. Introduction • Goal • Total Goal • Teach sensorimotor skill by Haptic User Interface. • 2nd Year Goal • Teach instrument playing. • First Step • Teach rhythm sense. • Why we select this Goal? • Two advantages • Tactile sensation is intuitive in playing instrument. • Tactile sensation can reduce the load of other modalities.

  3. Introduction • Why we select Drum? • It can simplify. • Terms • Pattern • Basic play unit. • Rhythm • A feeling can feel when pattern repeat regularly. • Tempo • Speed when playing pattern. • Beats Per Minute (BPM) • A unit for present Tempo

  4. Method • Stimuli design • Modality (Between subject factor) • Impact when hit timing • Flash, Audio, Vibration • Present next notes • Flow • Tempo (Within subject factor) • 45 BPM (1.33 sec / hit) ∈ Largo (very slow, 40―60 BPM) • 115 BPM (0.52 sec / hit) ∈ Moderato (moderately, 108―120 BPM) • 200 BPM (0.30 sec / hit) ∈ Prestissimo (extremely fast, ≥200 BPM) • Order • LMP, MPL, PLM, LPM, MLP, PML

  5. Method • Stimuli design • Total 24 experiment sets. • Four modalities X Six tempo orders = 24 sets. • Pattern • Right-Left-Right-Right-Left-Right-Left-Left

  6. Method • Apparatus • Overview

  7. Method • Apparatus • Electric Circuit

  8. Method • Apparatus • Experiment Program

  9. experiment • Participants • 48 POSTECH Students • Sex: Men • Ages: 17 ~ 25 (Average: 20.3) • Procedure • Preparation Phase • Pre-Test • Training 1, 2, 3 • Post-Test • 1-hour Term • Retention Test Preparation Pre45 BPM Pre115 BPM Pre200 BPM Train 145 BPM Train 1115 BPM Train 1200 BPM Train 245 BPM Train 2115 BPM Train 2200 BPM Train 345 BPM Train 3115 BPM Train 3200 BPM Post45 BPM Post115 BPM Post200 BPM 1-hour Re45 BPM Re115 BPM Re200 BPM

  10. experiment • Sample

  11. Result • Error Rate 1

  12. Result • Error Rate 2

  13. Result • Accuracy

  14. Future work • Three ways to extend this experiment • Use two hands with one foot. • Multimodality. • Two different signals in one modality.
