Research Tools - Headcam
 |
We
have developed a number of products and systems we use in our research.
The two main data-gathering platforms are the Networked Fire
Chief microworld software and the Head-Mounted Video
system used for capturing events from the first-person perspective
of the participant.
The supporting techniques for enhancing the data are the Two-Stage
Cued Recall Debrief and the Video-Based Eye Tracking.
A purpose built usability / simulation laboratory
has been designed for use when required. |
Headcam

|
The head mounted video camera cued recall methodology was originally
developed by Dr Mary Omodei as a flexible research and training
tool in 1994. It was used first in sport psychology research and
training , then in emergency management research and training. It
has been used subsequently in range of task domains. Headcam provides
a useful technique for conductiong field research by allowing the
non-reactive and continuous recording of events in real time.
Their use enables the capture of aspects of decision making which
hitherto have only been possible to measure in the constrained
environment of the laboratory.
Own-point of view video recording provides a particularly powerful
stimulus for evoking the recall of a wide range of cognitive and
affective experiences, thus affording a powerful method for prompting
the wearer to remember information about the incident and the mental
events that "drove" his/her decisions.
When the footage taken from a head-mounted video camera is used
with the Two-Stage
Cued Recall Debrief this combination proves to be a powerful
knowledge elicitation
technique.

The accounts which experienced fire officers have given in reaction
to reviewing video footage taken from their own point-of-view during
regular turnouts, has already provided a rich source of data for testing
competing psychological theories of human decision making.
Specifically with respect to firefighting, the use of head-mounted
cameras shows considerable promise as a means of studying decision-making
in-situ, particularly at large scale incidents. |
|
|
To
date we have used the head-mounted video camera successfully in
a range of operational and training contexts such as;
|
|
|
|
- Australian Rules Football Umpiring
- Senior Metropolitan Fire Ground Commanders
- Large scale Urban Search and Rescue simulations
- Competitive Orienteering
- Indoor Cricket Umpiring
|
|
|
|
|
Plans are currently underway to trial the new, lightweight headcam
system (as seen above) in domains such as motor vehicle driving, competitive
fencing and basketball refereeing. |
