We examine the visual influence of stabilization in
human sensorimotor control using a simulated inverted
pendulum. As the inverted pendulum is fully simulated, we are
able to manipulate the visual feedback independently from the
dynamics during the motor control task. Human subjects
performed a balancing task of an upright pendulum on a
robotic manipulandum in two different visual feedback
conditions. First we examined how subjects perform a task
where the visual feedback is congruent with the pendulum
dynamics. Second we tested how subjects performed when the
physical dynamics were fixed but the visual feedback of the
pendulum length was modulated. Subjects exhibited deficits in
the control of the pendulum when haptic and visual feedback
did not match, even when the visual feedback provided more
sensitive information about the state of the pendulum. Overall
we demonstrate the importance of accurate feedback regarding
task dynamics for stabilization.
