Currently there are many ways of representing physical environments, and options continue to rise with the constant innovations in computing.
As for display systems, new technologies offer a wide range of devices (screens, mobile devices, head-mounted displays, large format projective systems…) presenting each of them different characteristics (cost, level of immersion , stereoscopy, view of own body …).
As for formats, There have traditionally been used photographs, videos or renderings for presentation of stimuli in experimental studies. In recent years stands out 360º panoramic image, which combines the ease of generating scenarios with a greater sense of immersion.
On the other hand, the current processing power of computers affords to generate real-time three-dimensional environments with an acceptable level of realism, which will generalize the use of Virtual Reality. This new way of viewing stereoscopic and interactive first person, allows users to move freely through space, exploring it in a natural way and with great sense of presence (“being there”).
If the ultimate goal of environmental simulations is to represent the space as closely as possible to reality, it seems necessary to compare the results between different modes of representation.
In this sense the Research Group Neuroarchitecture LENI has conducted cross comparative studies between different display systems and before real spaces, both in indoor and outdoor environments and collecting the psychological and physiological response of users.
The team has extensive experience in the development and application of virtual environments research for all formats and platforms. The Laboratory has cutting-edge Head-Mounted Displays, large format CAVE and PowerWall projective systems, navigation devices by optical tracking and haptic sensors for interaction with virtual worlds.
