    The purpose of this thesis is the designing and development of a security system that can help a company and its workers with a variety of capabilities such as indoor location tracking and communication with a security supervisor. That security system consists of 2 web pages for the administration of the maps and the employees’ registration. There is another web page that only the security manager uses which allows the communication with an employee and, with his approval, the location tracking system that is meant for guiding. It also consists of 2 Android applications, one for the employees and the second one for the visitors. Lastly there is the backend system that manages all the data the websites provide making the communication of the websites with the applications feasible.

    A toolset for physical interaction in augmented reality environments.

    Augmented reality nowadays is constantly expanding, and its applications become widely known. This technology combines the real world with the virtual, allowing virtual content to be placed on top of the real world in real time, enhancing or even altering the real world. As this technology evolves, new methods of interaction are currently researched to provide a better and more organic behavior in such environments. One of these methods is the ability to track and identify the pose of the hands of the user in the environment. Using such techniques allows to simulate the hand behavior which describes the interaction with real objects into the virtual world. As the research on these technologies progresses, tools are required to provide the means for building applications taking advantage of such technologies. Most of these of tools are targeted towards a specific device or method and therefore cannot work if those are changed. Another limitation of these tools is that it is hard to expand their functionality if it is required. In this master thesis a toolset is developed to enable the interaction between the physical hand and virtual objects in augmented reality environments using the Unity game engine. This toolset provides basic functionalities of interactions and it is made in such a way that allows for the developers to expand the capabilities and the range of interactions as they see fit. Furthermore, the toolset has the ability to adapt to different technologies for hand tracking, making it more flexible on what methods will be used each time. It is also important to mention that given the technology is always moving forward, the ability to continuous integrate the latest methods into this toolset is a significant feature. The resulting toolset enables the development of applications using the aforementioned technologies with a few basic steps.
