Future technologies to help airline passengers experience increased comfort and space and an altered self-perception - Press release of Max Planck Institute for Biological Cybernetics and Fraunhofer IAO
Does this sound familiar? After a long check-in procedure you are finally sitting in your assigned seat on the aircraft. But the seat is too narrow, the foot-well is too tight, you have neighbors using both armrests, and the family with small children in the row in front increases the noise level considerably. If only there was a way to hide the environment or perhaps even create an illusion of comfort and relaxation! This illusion could soon become a reality, leading to a significant improvement of airline passenger comfort. Working together with seven other partners across Europe, scientists from the Max Planck Institute for Biological Cybernetics in Tübingen and the Fraunhofer Institute for Industrial Engineering IAO in Stuttgart within the project "VR Hyperspace" hope to realise this vision. This research project, which could transform airline passenger comfort, is led by The University of Nottingham in the UK.
Due to increasing passenger numbers and the limited space available in aircraft cabins, passenger comfort will be an increasingly important issue in the future. VR Hyperspace is a project in the 7th Research Framework Programme (FP7) funded by the European Commission, which explores new technologies to maintain and improve airline passenger comfort.
Recent research from neuroscience has shown that virtual reality is one amazingly easy way to produce the illusion of a different environment, or even altered body awareness. A total of nine different research institutions and industrial companies from six countries are working to develop such methods and to verify their suitability in terms of increasing passenger comfort in different application scenarios. The mixed and virtual reality technologies used range from the installation of a display in the surfaces of the cabin to complete immersion in a head-mounted display that can change both spatial and body awareness. The most promising developments of VR-Hyperspace are being integrated into the cabin of a motion simulator to put the new technologies to the test in a small space and even under extreme flight conditions, such as during turbulence.
As part of the project, Fraunhofer IAO has developed a mock-up of an aircraft cabin in which the plane's shell can be switched to "see-through mode". Passengers bothered by the seats in front can choose to make these transparent, too. Of course, this is possible only in a virtual sense: all the seat backrests are entirely covered in displays, with flat-screen televisions built into the floor and 14 projectors for projecting images onto the cabin walls. Effectively, the whole cabin is a display. Combined with a head tracking system, this lets passengers think they're not in a plane but on a magic carpet! For those who are scared of heights or nervous about flying, the displays can naturally also show other scenes, such as a tropical island or a stream running through a forest. There is also something special for the business traveler who can run current Office applications on the built-in display system, all the while enjoying the (virtual) sunshine of their own private island. Initial results indicate that the scenarios developed so far enable test subjects to experience an increased level of comfort and spaciousness and feel that time flies by more quickly.
The Max Planck Institute for Biological Cybernetics tests scientific outcomes on self and space perception during in-flight motions, .i.e. turbulence. The first results using fully tracked and immersive head-mounted-displays demonstrate that one can experience presence in a larger space (i.e. a beach), experience an altered virtual body (i.e. a more comfortable posture) and that the experience of the body size influences the perception of space. The question for the final months is if these positive illusions occur under flight conditions and/or can alleviate stress caused by experiencing turbulence in-flight? For demonstration the positive illusion experiences as well as physiological and behavioral measuring technology are combined within the CyberMotion Simulator to test the practical issue of using virtual reality when experiencing in-flight conditions i.e. turbulence. The CyberMotion Simulator is a novel all-purpose motion simulator that provides scientists the unique opportunity to test future scenarios of using virtual reality in flight while observing their behavior.
