Project Goal

• To conduct research for improving rehab patient
  care by applying
• Labanotation
• Computer modeling/animation techniques
• Wireless sensor tracking systems for specifying
  and recording rehab exercises.

4
Project Plan

• Task 1 Identify and record key rehab exercises
• Task 2 Derive the equivalent Labanotation and
  LMA for the key rehab exercises
• Task 3 Examine LabanDancer Software
• Task 4 Design rehab exercise specification/animat
  ion tool
• Task 5 WSN for recording rehab exercises
• Task 6 Evaluation the proposed techniques/tools
  for improving rehab care

5
Deliverables and Mile Stones

• Task1 -(2 months after the start of the project)
  
• Brief description of the selection rationale (
  rehab exercises)
• Data files and motion capture data from each
  exercises.
• Document that describes the set of selected rehab
  exercises in terms of current rehab terms.
• Task 3 Document that describes the results of
  task 3
• Task 4 Document that describes the evaluation
  results of task 4.
• Task 5 Document that describes the evaluation
  results of task 5.
• Task 6 Document that describes the evaluation
  results of task 6

What is Laban ?

• Captures dance movement on the page and
  interprets it thru symbols so that it can be
  shared
• By simply reading a symbol on a staff, one
  immediately knows 
• The direction of the movement.
• The part of the body doing the movement
• The level of the movement
• The length of the time it takes to do the
  movement.

7
Symbols

• The shape of the symbol tells you the direction
  of the movement.

8
Symbols

• A symblo can be used to show a step or a gesture
• A step is a movement that takes weight
• A gesture is a movement that dosent take weight.
• Eg. A forward symbol can either represent a
  forward step or a gesture

9
Symbol Placement

• Placement of the symbol tells us which part of
  the body is doing the movement

10
Symbol Shading

• Shading of the symbol tell you the level at which
  movement takes place.
• Steps- low level is with a bent leg, middle level
  is with a straight leg, and high level is up on
  the toes.
• Gestures - middle level is with the limb parallel
  to the floor. The hand or the foot is on the same
  level as the shoulder or hip. Low level is below
  this, high level above.

How to read ?

• Starting position - three beats to the measure, a
  quarter note getting one beat.Start with the
  feet together, knees straight. The arms are out
  to the sides, slanted down at a 45 degree angle
