Response Collection
The range of response collection devices includes low profile response keys that ensure
your participant stays comfortable during longer experiments, infra-red response keys that provide a way of having
non-feedback responses. It also includes voice-triggered keys or foot pedals that can be a solution when
participants cannot use their hands to respond.
The response devices are connected via the parallel port. If only two keys are needed the
devices can be interfaced as a USB mouse.
Prices exclude VAT.
RESPONSE KEYS

Low profile response
keys
These response keys are enclosed in a very low casing enabling the participant's hands and
lower arms to be in a more natural position. Ideal for longer experiments in
which the participant has to remain in the same position. The keys give a faint clicking
feedback. Can be provided in a one, two, three, four or five key configuration. Multiple
key devices can be arranged ergonomically for the left or right hand or positioned in a
straight line.

Infra Red non Feedback Response
Keys
These keys are great if you require a response that does not give any feedback to the
participant. Infra-red sensors register when something (like a finger) gets close to the
surface (less than two millimeter) and signal a key press. The output behaviour can be inverted so
that a key press is registered when an object/finger is moving away from the keys, registering for
example a finger lift. A single pad has three response areas small enough to use for single finger
responses.
£243.- per pad.

FOOT PEDALS
 |
Heavy Duty Foot Pedals
Foot pedals are a great alternative to hand and finger responses if the participant's hands need
to remain in a fixed position. Pedals can be used to register either press or release.
£122.- per pedal.
