AB  - Touchscreen devices have dramatically increased the accessibility and usage of technology, causing escalating usage, especially by very young children. Although the effects of screen time have been shown to produce serious (negatively effects on executive functioning, attention problems, school difficulties, sleep and eating disorders, and obesity) and even life-threatening consequences (due to radiation emission), technology can be beneficial if it is carefully used. Child-centered technology is especially designed to be as entertaining and captivating as possible. In order to examine how touchscreen devices, influence the acquisition of some important spatial concepts and provide exciting opportunities for learning new abilities, an experimental research was conducted aimed to determine whether the type of device used (computers or tablets) in the
natural kindergarten environment influences young children performances. For the purpose of this work, geometrical symbols on traffic signs were used to test spatial relationships – left/right, and longer/shorter relations. The test was carried out on a sample of 30 pre-school children. The results show significant differences between the two-testing media for identifying the longer vs. shorter relationships in favor of Tablet PC. Based on the results obtained, it can be concluded that the kinesthetic characteristics of tablets, the novelty factor and the opportunity to learn through playing, provide a positive approach to the early childhood education. Besides, the interactive environment created in a kindergarten by using tablets contributes to introduce new teaching methods which are expected to amplify the pedagogical capacity, changing the way of
spatial concepts acquisition, as well as, children traffic education take place within.

AB  - Excessive speed and poor drivers' perception are the causes of a large number of traffic accidents. Analysis of the influence of geometry in drivers' behavior has been widely performed by different researchers. One way to improve road safety is to provide adequate visibility in order to help drivers adopt adequate behaviors. When the budget is not sufficient for expensive traffic solutions, innovative but simple solutions can be implemented. In this study, the experiment was performed to explore how drivers' perception and behavior are influenced by two virtual 3D shapes' projections - a 3D alternative crosswalk pattern and speed bumps consisted of triangular prisms. The results show statistically significant differences between drivers' willingness to reduce vehicle speed as a response to the two types of road markings: the first one with the square shape base (rectangular prism) and the second one with triangular shape base (triangular prism).

AB  - Modern education systems and curricula attend are largely based on the application of new technologies. The traditional way of working on subjects from group based on engineering drawing using computers includes adequate theoretical training and practical exercises which are solved by drawing and constructing a pen and aids on paper. The modern method has brought numerous news. The tasks that were solved with a pen on paper, in this case, are solved by using computers and appropriate software tools. There has been a wide acceptance of CAD software packages. Spatial visualization skills is the ability to which it is the application of new technologies and specialized software had both a positive and a negative impact. Due to the great importance of this skill in all areas of engineering, it is necessary to work on its improvement. This present study was designed to determine challenges and promises of mobile devices usage for spatial visualization skills and achievement in Technical Drawing for Engineering course for students at University of Belgrade.

AB  - Children represent a vulnerable population from the standpoint of traffic safety. A modern traffic poses complex and high requirements to all its participants, and among them, particularly to young children. Children have a higher risk of pedestrian injuries. Children are experiencing experience traffic differently from adults. How do children view the world? What helps them to link with their environment? How do children imagine traffic signs? To address these questions, this study examines how fast the children (between 6 and 10 years of age) react to traffic signs mounted at different heights. The analysis of the results indicated that there were differences in mean reaction time for traffic signs of different heights. Children best perceive a traffic sign when it is mounted at 1.9 m. The research highlights the importance of ergonomic principles in choosing the appropriate height of traffic signs for children.
