Control algorithms developed for autonomous and electric vehicles undergo limited trials because of the high cost of using actual vehicles. This study constructs a low-cost virtual environment for developing such control algorithms using open data and a game engine. Specifically, a large-scale three-dimensional urban road model with elevation differences is generated. This model is connected with hardware-in-the-loop simulations (HILS) as a vehicle running model to realize a practical system. This study reveals the need to automate the model development process in light of its high cost.
In the growth process of children, playing with dolls contributes to the formation of the self, creativity, and social development. In general dollhouse play, children move the dolls and imagine the world of the dollhouse. In this study, we installed sensors of distance and pressure in a dollhouse, and projected interactive images according to the measured values by projection mapping. It became possible to expand the doll play by generating the image corresponding to the movement of the dolls and hand in real time and reflecting it in the doll house.
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.
