Abstract:In this paper is presented an experimental study that aims to compare the depth perception of virtual prototypes in immersive virtual environments with the depth perception of CAD models using 2D LCD display. First, a multipurpose solution of a large-scale interactive multi wall projected virtual environment named Holo-CAVE is described and then the conducted experiments are presented. The experiments carried out highlight that perceived depth values estimated for virtual prototypes are significantly influenced by the 3D stereoscopic visualization. Another interesting result of the study is that the estimated depth accuracy increases with the depth size that has to be perceived. The results of experimental study illustrate that the use of immersive stereoscopic visualization is useful during Computer Aided Design related activities.
Abstract. We present the architecture of an Advanced Driver Assistance System (ADAS) based on common dual camera smartphones, emphasizing on the calibration procedure which is active during the initialization phase (prior to the actual driving). NAVIEYES project attempts to make use of the video information received from both the front and the rear cameras of the phone in order to infer and alert drivers upon potential dangerous situations. This study focuses on the information received from the front camera. 10 different mobile devices were tested, in order to choose the most powerful and ergonomic platform. A calibration experiment is carried by 22 subjects, and the first version of the application is tested using a driving simulator. The system is deployed on a real car, and several warning paradigms such as audio, video and mixed alerts are also analyzed. We present the HCI questionnaire, analyze the data and propose further developments.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
