5The LUTIN lab
- Architecture constrains
- 1 lab around a fireproof structure (ceiling,
floor, external walls) - 6 rooms divided in
- 1 observation room with 2 main Observer Stations
- 5 test rooms with 6 test environments
6Prerequisites for Test Rooms
- Each rooms has to be equipped with camera,
microphone, loudspeakers and a tool to capture
the screen of the test PC in high resolution - Position of cameras and microphone can be chosen
depending on test protocol - Cameras can be controlled from the Observation
room - Additional video input for other hardware
(miniature camera, VCR, mobile device camera)
7Prerequisites for Observation Room
- 2 Observation stations
- Each station can control independently all
cameras, in/out audio signals and test PC - Each station can record the video/audio/screen
data from a chosen test room (can be identical
for both stations) - Information from the camera and screen of a test
room can be visualised at the Observation Station - Information is recorded digitally and analysed
with chosen level of details use of The Observer
Video-Pro

10Technical choices
- Centralized Processing
- All data from test rooms are sent via high
quality shielded cables to a central management
and processing unit and then dispatched to the
two Observation Stations
11High Quality Components
Components have been tested for perfect
compatibility and preassembled at Noldus
12Controls
All video data can be visualized and controlled
from the Observation Stations Use of matrix
system, dome cameras and several preview and
recording monitors
13Selection of data
- We used video quad units and splitters to allow
the best possible choice of camera view angles - Overlay boards and Mpeg encoders allow to
display and record simultaneously the camera
images and screen capture of the test PC
14Screen Capture
- We used advanced KVM switcher and CAT5 network
based solution to provide high quality and fast
screen capture of the Test PCs - Scan converter was not a viable solution in this
case
15Final Solution
Provided with integration, installation, on-site
training, tailor-made manual and technical
support (and nice dutch-french-belgian mood ?)
