Abstract
A small-motion test device especially useful as a welding aptitude test and primary training device comprises a target movable along a linear track, and switch means for defining a multi-dimensional envelope of freedom of movement of said target. A wand held by the test subject must affirmatively position the target within the envelope, and maintain it there throughout the time of the test while the target moves along the track at a preprogrammed rate. Success of the test is indicated and accounted for as a function of the percentage of the total test time that the target remains within the test envelope.
Claims10
A small-motion test device for testing the hand-eye coordination, correction reflex, and small-motion muscle control of a test subject comprising
- a target
- means for moving said target along a path at a predetermined rate,
- switch means coupled to said target for defining boundaries of a multi-dimensional envelope of freedom of movement of said target,
- a wand controlled by said test subject to affirmatively position said target within the boundaries of said envelope of freedom of movement during travel of said target along said path, and
- means responsive to said switch means for indicating the location of said target within said envelope of freedom of movement.
A method of testing the small-motion muscle control, hand-eye coordination, and correction reflex of a test subject comprising
- moving a target along a path at a predetermined rate,
- defining the boundaries of a multidimensional envelope of freedom of movement of said target by electro-mechanical switch means,
- providing a wand to said test subject, said wand being used by said test subject to controllably position said target within said boundaries of said envelope of freedom of movement through movement of said target along said track,
- the location of said target within said envelope being indicated by indicating means responsive to said switch means.
