DAF's VR project


Light sources in both passenger cars and commercial vehicles cause reflections in windows. Due to building space, viewing angles and window positions/angles, it is a challenge for commercial vehicle manufacturers to position these reflections non-disturbingly in left side window. Therefore we would like to gain insight knowledge in variables which have an effect on these reflections and their effect sizes. In addition, DAF Trucks wants to experience and assess the quality and realism of virtual validations by using CAVE technology.



DAF’s objectives for this assignment are twofold:

  • Understanding which variables have what kind of effect on light reflections in left side window
  • Experiencing & assessing the quality and realism of virtual validations by using CAVE technology



1. Collect necessary DAF 3D CAD models (Unigraphics)

2. Plot the experienced reflections from the DAF Instrument Panel (DIP) in left side window for P05, P50 and P95 percentile eye points.

3. Create test environment within the CAVE by using a height adjustable chair (office chair) and steering wheel in order to make Virtual Reality experience as realistic as possible for test persons.

4. Validate virtual reflections with the test persons (approximately 3 DAF employees) in the CAVE test environment.

5. Make an inventory of variables which are influencing the DIP reflections in side window.

6. Plot the adjustment ranges on the side window for each variable (separately)

Support and evaluation


Arno Roijackers (Vehicle property owner Ergonomics) will support the students with respect to the content and set-up of the validation test. The students will get the opportunity to meet him on a weekly base at DAF Trucks. Michel Erich (3D CAD specialist) will be available for 3D CAD support regarding Unigraphics.

Time schedule


The students are supposed to work 1 day per week for this assignment from the 5th of September 2011 until the 27th of January 2012.
