    Abstract: This paper show cases the production steps undertaken in the creation process of a three-dimensional, virtual museum-like environment, accomplished using the cross-platform Unity 3D and the aid of a third-party mixture of media production and editing tools. The consequent goal of the process is creating a commercial application available to users operating on a Microsoft Windows environment or (and) a mobile device running a version of the Android operating system.

    Abstract: Car transport is crucial for society and has grown in terms of both number and complexity of the vehicles, their interaction and the traffic situation. The emergence of the technology focuses mainly on reducing human effort in every field. This paper proposes the development of an automated, easy-to-integrate and cost-effective electronic system model that will help reduce collisions. The developed system can be considered as a step towards minimization of mental and physical efforts made by the driver to control the vehicle safely. Collision avoidance is a research area that has become more relevant in recent years as the vehicles have been improved by adding driving assistant systems.

    Abstract: Hand gesture recognition systems can be used as instruments to simplify the way humans interact with computers and other smart electronic devices that are bolstering our home and office comfort or security day by day. In this paper, a hand gestures recognition system has been implemented, that is able to recognize 10 static gestures from The National University of Singapore hand posture datasets. The first stage of the proposed system consists in detecting a bare hand in a plane background image and extracting the Hu invariant moments using Open Computer Vision (OpenCV) platform for Python. The second stage takes as input the characteristics file and, using A Library for Support Vector Machines (LIBSVM), trains and generate the classifier model. Finally, it provides the option to recognize hand gestures using multi-class Support Vector Machines (SVM) algorithm.

    Abstract: This paper explores the possibility of a car renting system for private car owners. Current systems require the renter to bring back the car themselves or employ the use of still-not-perfected self driving vehicles. We propose that a car can hitchhike by taxing the renters that abandon it and paying drivers to take it closer to home. For this purpose we developed a mathematical model based on existing technology and approaches. We also propose a implementation architecture. We model continuous sanctions for renters that do not take steps to return the automobile to the owner at the desired time and place. We also present a game theory analysis of the utilities of both drivers and owners. The result is that longer trips are more advantageous for all involved. We also introduce a formula that can calculate the moment when the driver should start heading back in order for the system to be able to find a replacement driver, if needed. We found the system to be robust and safe to use, i.e. there is no hidden utility for the driver or the owner to act in bad faith.

    Abstract: In this paper, the authors presents an implementation of real car game application - finding the signal. A such of intelligent prototype allows the user to control the car on a given lane, detecting as many magnets while traveling above them during the pre-established time in the microcontroller program. As the time expires, the score which represents the number of magnets detected will be sent to the application through serial communication.
