The 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

The Observer 5.0

Prerequisites 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)

The Observer 5.0

Prerequisites 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

Technical 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

High Quality Components

Components have been tested for perfect compatibility and preassembled at Noldus

Controls

All video data can be visualized and controlled from the Observation StationsUse of matrix system, dome cameras and several preview and recording monitors

The Observer 5.0

Selection 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

The Observer 5.0

Screen 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

Final Solution

Provided with integration, installation, on-site training, tailor-made manual and technical support(and nice dutch-french-belgian mood )
