An fMRI-compatible computerized tablet system has been
previously developed in house to be used for complex
Neuropsychological testing such as writing. The tablet
did not include visual feedback of hand position (VFHP),
a human factors component that may be important for fMRI
of certain patient populations. Because the user is
lying in the magnet bore, they cannot view their hand
during this process and must rely on their sense of
proprioception. A real-time system was thus developed to
provide VFHP and integrated with the tablet in an
augmented reality display. Attempting to visualize the
hand position during performing such complex motor
movements may induce excess subjects head motion. We
assessed the influence of VFHP on head motion and the
associated brain activity involving a set of handwriting
tasks in young healthy adults.
