Noldus Information TechnologyTechnical
Competences
  • Observational data collection
  • Handheld computer technology
  • Video coding, annotation, retrieval
  • Digital image processing
  • Pattern recognition
  • Behavior analysis
  • Signal analysis
  • Experiment automation

3
Core Activities
  • Software Development
  • Standard software packages
  • Custom development on contract basis
  • System Integration
  • Noldus software
  • Computer hardware
  • Video and multimedia equipment
  • Portable or stationary observational laboratories
  • Training and Consulting
  • Services (support, conference organisation)

4
Integrated Solutions
  • Tailor-made observational labs and systems
  • System configurations
  • Stationary Lab
  • Portable Lab
  • Mobile Data Collection Systems
  • Mobile Device Camera

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

6
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)

7
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

11
High Quality Components
Components have been tested for perfect
compatibility and preassembled at Noldus
12
Controls
All video data can be visualized and controlled
from the Observation Stations Use of matrix
system, dome cameras and several preview and
recording monitors
13
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

14
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

15
Final Solution
Provided with integration, installation, on-site
training, tailor-made manual and technical
support (and nice dutch-french-belgian mood ?)
