- Automotive virtual reality platformPublication . Mendes, Filipe Ramos; Matutino, Pedro Miguel Florindo Miguéns; Santos, Nelson Filipe Pereira dosAbstract Nowadays virtual reality (VR) is becoming a leading topic in technology, as it provides a way for the user to immerse themselves in a virtual environment, that no other technology until now could provide. The user can perform actions and movements in the real world and watch them take place in the virtual world. The proposed project intends to take advantage of this technology and design and implement a virtual reality driving simulator. The project is naturally composed of different components. The main one is the Stewart platform, which is connected to the driving simulator software that in turn is connected to the input devices, which include VR components such as the VR headset, and the driving components, such as a steering wheel and foot pedals. A Stewart platform is an electromechanical system that in short is composed of a flat platform controlled by six linear actuators, which work together to provide rotation and translation movements on the three axes, resulting in six degrees of freedom (6 DoF). The driving simulator software is responsible for the vehicle’s mechanics, how the vehicle brakes, accelerates, and steers. It receives the user’s input, from the different input devices and transforms it into data that will be sent to the platform’s software. It also provides a visual representation of the environment that will be shown to the user, for example, through the VR headset. The project herein depicted implements a prototype of the overall system and performs several test scenarios, together with the Stewart platform. Besides aiming to bring a realistic experience to the user using the simulator, this project was also developed with a high focus on the separation of functionalities, which means that each component described above could be replaced by a similar one, with the same purpose, without affecting the system.
