11. GLOSSARY

Remote PC

A remote PC is the computer or other equipment which is running the paradigm you wish

to benchmark the timing of.

Host PC

The host PC is the Microsoft Windows 2000 or XP based desktop or laptop that is

physically connected to the Black Box Toolkit via its parallel port. This PC controls the

BBTK and carries out all timing analysis.

Active switch closure

Active switch closure is where the Black Box Toolkit closes a switch or key on a response

device on the remote PC. For example the toolkit may make a simulated response by

holding down a mouse button of the remote PC. This is accomplished via a switch closure

lead that is physically attached to a switch on the response device.

Passive Switch Closure

Passive switch closure is where the Black Box Toolkit detects a suitable switch closure on

a response device on the remote PC (see 13.3.1.). For example if a human presses a key

on a remote response device this can be detected simultaneously by the BBTK.

BBTK Digital Tone Generator

A digital tone generator is a specialised digital sound producing device that is used by the

Black Box Toolkit to trigger voice keys on remote PCs.

BBTK Digital Microphone

A digital microphone is a specialised microphone that is used for detecting sound stimuli

produced by the remote PC.
