A device measuring approximately 14.5 X 8 X 4 cm, designed to serve as an interface between an adaptive switch (with a normally open switch closure) and sources of stimulation (e.g., vibrator, CD player, mechanical toy). The interface was designed to enable evidence-based evaluation of such switch use. The interface records and displays records and displays:

total use (session) time
cumulative duration of switch closure per use
number of switch closures per use

The interface was designed to enable environmental control in novel ways. It permits switch closures to:

initiate operation of a source of stimulation
initiate discontinuation of a source of stimulation
toggle between two sources of stimulation

The interface has an on/off switch, a pause switch, and an output port for sending event data to devices that can log data in real time for post-session analyses (labeled Hobo Output in the picture).
