Maintaining physical balance is a complex task mediated by input from multiple sensory input sources. While the vestibular system is responsible for detecting the location and movement of the head in three dimensional space, input from proprioceptors regarding limb location and joint position, as well as input from the visual system, are also very important. When one of these input sources is distorted or removed, it becomes difficult to maintain balance, especially in challenging situations. The sensation of losing one's balance typically results in compensatory movements of the body as the subject tries to regain stability. These movements can be measured to determine how well a subject is able to maintain balance under different conditions. Less stability results in larger and more frequent movements.

In this activity, you will explore your ability to balance with and without visual input using a Force and Acceleration Sensor to detect movement (measured here as acceleration). You will also compare your balance when standing on one leg at a time, and determine whether there is any difference between balancing on your right and left legs.


  • Measure your stability while attempting to balance with your eyes open and closed.
  • Compare your ability to maintain balance on your right and left leg with eyes open and closed.
