In July 2014, we asked two of the survey participants to test our bridge demo as well as the first version of the lift. Since November 2014, we have been collecting quantitative data regarding our lift experiment. Furthermore, we conducted a qualitative interview with a client only a few days ago. Through this, we have been able to get in touch with the Fraunhofer institute in Vaihingen, where research studies in virtual and augmented reality have been conducted for over 30 years. As our online survey carried out on 11/09/2015 has shown, VR hardware products are mostly known among VR enthusiasts. However, even the average citizen at least heard about Google Cardboard and Oculus Rift. The products used most commonly were the ones available on the consumer market: Samsung Gear, Zeiss VR One and Google Cardboard, whose construction manual is available under an Open Source license. Oculus Rift has often been used as a showcase for head-mounted displays, because at the time, its prototype version was available for developers. HTC Vive, which has been developed in collaboration with Valve, has also often been used to showcase head-mounted displays. Valve runs Steam, the worlds largest online gaming platform with over 35 million users and 1800 games. In addition, more than 80% of the survey participants stated that they would use VR hardware for gaming purpose in the future.
In April 2014, we evaluated our research on fear of heights. Over 200 people participated, with 52% of them suffering from acrophobia. This gave us important basic knowledge about our potential clients. 50% of the participants would conduct a cyber therapy.
