The Observer 5. 0 Innovative Solutions for Usability Testing Design of a Usability Lab Titel Spreker th 2004 La Villette, November 24 Datum Dimitri Gerebtzoff Field Sales Engineer - France

The Observer 5. 0 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…)

The Observer 5. 0 Integrated Solutions Tailor-made observational labs and systems System configurations • Stationary Lab • Portable Lab • Mobile Data Collection Systems • Mobile Device Camera

The Observer 5. 0 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

The Observer 5. 0 Boxed design of the lab: versatility Video

The Observer 5. 0 Boxed design of the lab: versatility Audio

The Observer 5. 0 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

The Observer 5. 0 High Quality Components have been tested for perfect compatibility and preassembled at Noldus

The Observer 5. 0 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

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 CAT 5 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

The Observer 5. 0 Final Solution Provided with integration, installation, on-site training, tailor-made manual and technical support (and nice dutch-french-belgian mood )
