PromptResponse
Human Experiment Research Software
|
|
|
PromptResponse facilitates an experiment technician
to communicate remotely to a human subject in an isolated room.
Typically, human experiments present a human subject with a stimulus,
while the subject is prompted for a response.
PromptResponse initiates a prompt of the subject and solicits a response.
|
|
PromptResponse supports any type of stimulus (visual, aural, haptic, etc.),
prompts the subject visually and/or aurally,
samples sensors prior, during, and after stimulus,
and solicits responses in a variety of methods, including verbal, gestural, or manual.
|
|
The PromptResponse software consists of three components:
a server running on the subject's system,
a client-library running on the experimenter's system, and
a Matlab interface and test suite running on the experimenter's system.
PromptResponse runs on any MS Windows compatible platform and communicates over TCP/IP.

The client side initiates actions, while the server side responds to action requests.
The experiment technician typically pilots or oversees the client side,
while the human subject interacts with the server.

Recent installations:
- Winter 2010, Aberdeen Proving Grounds, MD -- Environment for Auditory Research (EAR)
Army Research Laboratory (ARL) human performance research group (HRED)
relies on PromptResponse as the enabling technology of there human subject experiments.
PromptResponse communicates from any of five control room workstations or any visitor laptop
to any of the three subject chairs, outfitted with sensors and touch tablets.
