Handwriting / Drawing Movements

Kinesiology Please visit our newer page for MovAlyzeR® in kinesiology, here.

Application areas

  • Kinematics of handwriting
  • Handwriting performance/learning/skill acquisition
  • Handwriting as an indicator

Examples

  • Measuring effects of environmental factors on handwriting
  • Handwriting in children, young adults, elderly and patients with movement disorders
  • Studying the effects of drugs through handwriting performance

Relevant Features

  • Measures speed, size, and variability in mouse and pen strokes and many other features
  • Delivers an indication of the functioning of the neuromotor system
  • Multiword segmentation
  • Submovement analysis
  • Real-time feedback of handwriting
  • Kinematic parameters can be extracted, plotted and exported
  • Statistical analysis of data

Teaching / Demonstration

Application areas

  • Courses focusing on human motor control, development, performance, behavior or skill acquisition, human kinetics, gerontology, psychology, movement disorders
  • Demonstrations and seminars for students on concepts involving fine motor system.

Examples

  • Demonstration of Fitt's Law
  • Handwriting/goal-directed movements

 

Bimanual Tasks / Grip-Pinch Force Measurements

GripAlyzeR Please visit our GripAlyzeR™ page, here.

Many tasks require producing a specific grip force with one or two hands, e.g., opening a capped bottle. A unique device has been produced to measure the grip in each and the pulling force as a function of time.

Application Areas

  • Isometric grip force measurements
  • Bimanual force coordination- Simultaneous measurement of both hands
  • Force segmentation
  • Pinch-force measurements
