HeadSpot is a general purpose chinrest made by UHCO Technical Services and built for observer position establishment in psychophysical experiments in vision science. The HeadSpot consists of a chincup and forehead rest mounted as crossmembers between a pair of vertical posts. Both are adjustable vertically along the entire height of the post: eighteen inches. The lower extremities of the posts are mounted in clamp members which firmly attach to a table or bench top between 3/4 to 1-3/4 in thickness. The chincup is adjustable in a fore-aft direction by about +/- 1 cm. on its crossmember to allow adjustment of the "pitch" angle of the head and/or to accommodate differing chin-protrusions.
The structural posts are of aircraft aluminum alloy. Crossmembers and chincup are molded of polyurethane. The clamp members are polyurethane. Clamping and adjustment screws are steel. The finish of the entire unit is "optical" black.
The unit has been built to reliably locate an experimental subject. Its rigidity will withstand a lateral force of about fifteen pounds without deflecting more than a centimeter.
Two optional versions are available: the WIDE version and the TALL version. The wide unit will accommodate most head-mounted apparatus including the SR Research EyeLink system. The tall version is useful for lower table tops or extra tall observers.
