Human Computer Interaction Prof. Dr. Patrick Baudisch Masterprojekt Sommersemester 2016 Virtual Reality: Haptic Squatting Background Modern virtual reality systems, such as the HTC Vive allow users to walk around freely in virtual experiences. As a consequence, the most expensive resource consumed by such systems is not the headset or graphics system anymore, but space itself. The key idea behind the haptic squatting project (squatting = “Hausbesetzung”) is not to rent such space in the form of large apartments or gyms, but to instead use public spaces, such as Potsdam Hauptbahnhof. The software/hardware you are your team mates will write You will implement a hardware/software system that allows a VR experience to be played back in a crowded public space. Your main challenge will be to prevents users from accidentally bumping into stairs, escalators, or other people. Instead, you will integrate these elements into the experience in a meaningful way, so that physical stairs are located where users’ experiences also have stairs and where users bump into obstacles only where their experience says they will. Your system will cover the following functionality. Offline tools: 1) Survey the available space: Digitize the map and map out the resources offered by the location, such as cold area, staircase, escalator, revolving doors, and moving walkways. 2) Define the VR experiences in a modular format for that it consists of tiles connected by generic paths. 3) Re-layout the experience so as to map to the available space. And at runtime: 4) Render the world in Unity 5) Track the user inside the space. We will offer a Microsoft Hololens for that purpose. 6) Track obstacles: Track moving obstacles and integrate them into the experience. 7) Sense collisions etc. e.g., using accelerometers to sense how the user is affected by the environment. You will use Windows Holographic (HoloLens) and Gear VR for VR in public spaces additional data tracking data request
