The Space Systems Lab has evaluated several different
types of generic hand controllers to see which performs
the best when used by a suited subject. This paper
outlines the types of hand controllers selected for this
experiment and the results of the performance testing.
The evaluation was conducted by subjects wearing
spacesuit gloves in a partial pressure glovebox at a
pressure differential of 4.3 pounds/square inch.
Performance for each hand controller was measured by
the completion of several one degree-of-freedom (DOF)
tasks presented to the subject on a computer screen.
Performance metrics for this experiment included the
error associated with attempting to follow an ideal
