Perceptual Intelligence Lab

The Perceptual Intelligence Lab (π–Lab) is a centre of expertise for the study of human perception and the ecological properties of the physical world. Although we study all modalities we presently focus on human vision and optical properties of light and materials.Our expertise includes the functional understanding of human perception and the ecological constraints of the world. 

The π–Lab is a collaborative effort of the groups Man Machine Interaction (MMI, faculty of Electrical Engineering, Mathematics and Computer Science) and Human Information Communication Design (HICD, faculty of Industrial Design Engineering) of the Delft University of Technology.

The main aim of the π-lab is to apply the expertise in perception to the design of user-centered applications. We have defined three specific projects, namely:

  • Intelligent lighting solutions
  • Collaboration at a distance in computer mediated settings
  • Virtual and mixed reality for social interaction 

Facilities π-Lab

This laboratory is a multipurpose space for all kinds of perceptual research. The lab is equipped with various monitors, a stereoscope, calibration equipment, an advanced lighting system in the ceiling, etc. 

This laboratory is a space allowing for all kinds of photometrical research. The lab is equipped with unique custom-made equipment such as a Ganzfeld (diffuse light field) box, a goniometer, a lighting dome, a plenopter (light field measurement device), etc. Additionally, it contains various cameras, (il-)luminance meters, a spectroradiometer, lighting, calibration and positioning devices.

In the Sound lab all kinds of sound research in the field of design and perception of product sounds is performed, both on consequential sounds (result of operating of mechanical parts) and intentional sounds (intentionally incorporated, e.g. feedback sounds).

This lab allows for studio-photography and all kinds of psychophysical research. It is located directly next to the Light Lab, allowing for joint use of equipment.
