• Advanced computer vision techniques and the ubiquitous availability of depth cameras, multitouch hardware, and 3D sensors in mobile phones have significantly extended the possibilities on the input side of interfaces—not to mention the developments in brain-computer interfaces.
• We're also big fans of work on perceptual illusions, such as redirected walking and touching.
• The perception of self, others, and space in virtual environments is an important issue in many applications—for example, in the automotive industry when simulating a car's interior.
• The recent surge in 3D movies and games has renewed public awareness about 3D technology's potential and brings many new spatial interfaces in the forms of 3D TV and interaction into the home.
• Multiuser 3D displays are an enabling technology for virtual and augmented reality that was missing for many years and are slowly becoming available in various forms.
• The omnipresent depth cameras in combination with multiuser 3D displays are reviving immersive-telepresence research with the promise of holodeck-like encounters of groups of remote people.
