Comparisons of Interaction Techniques between Stroke Survivors and Healthy Subjects in a Haptic Collaborative Task

  1. 1. Collaborative Haptic Interactions Michael Bowler – University of Hertfordshire
  2. 2. ‘Phantom’ Haptic DeviceCollaborative Haptic Interactions - Michael Bowler 12/07/2012 2
  3. 3. Goals  Modes of collaboration  Understanding movement  Establish learning of the task  Influence design of future systems  Test networked haptics and model of collaboration for future workCollaborative Haptic Interactions - Michael Bowler 12/07/2012 3

  6. 6. Collaboration ProtocolCollaborative Haptic Interactions - Michael Bowler 12/07/2012 6
  7. 7. Experiment 1 - Haptic Collaboration  300+ participant over 3 daysCollaborative Haptic Interactions - Michael Bowler 12/07/2012 7
  8. 8. Experiment 2 – Home-Based Rehabilitation  4 stroke survivors  12-weeks of haptic assessment and exercise tasks  Participants have suffered some level of upper-limb impairment as a result of their stroke.  Participants >6 months post stroke, with no further strokes within the last 6 months.  Participants were not receiving any other therapy for hand and wrist function.Collaborative Haptic Interactions - Michael Bowler 12/07/2012 8
  9. 9. Why home-based?  Can be more effective at home  Can reduce costs  In the comfort of own home  Likely to exercise more frequently and with greater variabilityCollaborative Haptic Interactions - Michael Bowler 12/07/2012 9
  10. 10. Shape Preferences  Four shapes: Box, Star-shaped block, Cylinder, and a Sphere.  Two categories: curved sided, and flat sided.Collaborative Haptic Interactions - Michael Bowler 12/07/2012 10

  17. 17. Limitations  There was no continued/follow up which may may have shown further increases in task performance and a demonstration of learned skill for the task for the healthy group.  Interaction pairs in the stroke group consisted of the participant and the investigator providing an interaction bias.Collaborative Haptic Interactions - Michael Bowler 12/07/2012 17
  18. 18. Conclusions Different shapes afford different movements/interaction paradigms Curved surfaced shapes can be used for fine motor skill practice Flat sided shapes can be used for strength/stamina building exercises
