Usability Testing to Measure Real Perception Generation Level in Introduction of Bengkulu University Building Based on Virtual Tour with 360° Object Modelling

The development of photography technology creates a 360 ° camera that carries an ultra-wide twin1-lens folded optical lens (a small double lens with a folding design). This technology can produce spherical panoramic images. Spherical panoramas are borderless and seamless image objects used to create virtual tours. Bengkulu University, with the broadest environment in Southeast Asia, has more than 30 buildings with several floors and rooms. It's making it challenging to find the location of the building or event for incoming guests. The purpose of this study is to analyze the level of generation of a real perception of the introduction of the Bengkulu University building by a 360 0 virtual tour application. Usability testing is intended to analyze the level of perception generation, to introduce the Bengkulu University building to the guest. This research was carried out by collecting 360 0 photos for each building and room, then built a webbased virtual tour application that can display the location and directions to go to the building or office, then information on each building or outdoors will be displayed according to the shape of the object model 360 0 . Users can run a virtual tour application using a smartphone and VR-box to get a real perception like being in the building or room. Usability testing is done by making a questionnaire based on three components of usability testing (effectiveness, efficiency, and satisfaction), to obtain the level of perception generation from buildings with 3600 object modelling. Usability testing of the 360 0 Virtual Tour of University Bengkulu was carried out with a total of 100 respondents. The results were obtained by generating of usability testing were 94% (Effectiveness 96.1%, Efficiency 96.6%, and Satisfaction 89.2%).
