University's interactive display with Sony's ‘world’s brightest 3LCD laser projector’

An interactive information wall has been installed at the NTNU in Trondheim, Norway using a combination of laser technology from Sony and Microsoft Kinect. The university is one of the main institutes for higher technological education in Norway, with the information wall located in the Faculty of Information Technology, Mathematics and Electrical Engineering (IME).

The information wall presents a slide show of pictures from events and student activities and projects. The pictures are projected using a VPL-FHZ700L 3LCD Laser Light Source projector from Sony, delivered and installed by Sony’s dealer Caverion. The laser projector is said to be the world’s brightest 3LCD laser projector, featuring 7,000 lumens brightness and WUXGA resolution. The projector is on for 10 hours a day; one reason for the VPL-FHZ700L was chosen for its ability to operate for approximately 20,000 hours without maintenance.

In addition to the slide show, the information wall has an interactive 3D model of NTNU’s main building. Here, visitors can take a virtual trip around the building with the help of the Kinect’s motion sensor. The 3D system plays when a person stands in front of the information wall and the motion sensor detects the movement. They can then control the presentation with their hands and explore the 3D model in order to become more familiar with the university’s main building.

Dag Nummedal, head engineer at NTNU, commented: “We chose Sony because we needed high brightness, low running costs and high operational reliability. Our hope is that the projector and the rest of the installation are so robust that our visitors always enjoy spending time at our information wall.”
