Low-latency precision head-tracking allows distortion-free and lag-free movement through a virtual environment.
Immersive Displays Lab
Malet Place Engineering Building, ground floor
The Immersive Displays Lab comprises a CAVE™-hybrid projection theatre in which the user is presented with high-resolution stereo-pair images projected in real-time on 3 walls and the floor. When viewed through lightweight shutterglasses, the stereo images are presented separately to the left and right eyes respectively, producing the illusion of 3D objects appearing both within and beyond the walls of the room. The images are presented with reference to the users viewpoint, which is continuously updated via a head-tracking unit; thus as the user moves around, the environment displayed will always be perspective-correct.
UCL’s Immersive Displays Lab utilises a variety of technologies to enhance the illusion of immersion. Since its inception in 2000 the lab has incorporated novel technology advances in projection, tracking, acoustics and interaction to remain at the state of the art.
The displays can be driven by either a 5-node PC cluster, or by a single machine running the Unity game engine. This makes applications for the Immersive Displays Lab not only easy to write but also highly portable. Interaction with the environment can be achieved via a proxy object that is mapped onto the hand-held tracker or robotic arms directly on site.
The Immersive Displays Lab at UCL is used for cutting edge interdisciplinary academic and industrial research. Studies such as the Violent Emergencies bring together teams with different backgrounds and interests, enabling the study of wide-ranging phenomena in a virtual setting that would in reality be too dangerous or costly.
Apart from general academic research and industrial studies, the Immersive Displays Lab is also used for student projects during the COMPGV07 Virtual Environments module at UCL. The aim of the coursework is to develop and test an immersive application that encompasses interaction within the virtual environment the purpose of which is to teach the user a new skill.
At the end of the term student teams gather and showcase their creations to the lecturers and each other.
