Four of most of popular Bulgarian application were selected, namely “100 Places Bulgaria“, “I Love Bulgaria”, “Опознай.bg“ and ”The one hundred national tourist sites of Bulgaria”, and compare them. Data collection was performed through an electronic questionnaire, which was based on Google Forms. The article presents the need for a solid theoretical foundation for understanding the complexity and multi-layeredness of user experience (UX) and user interface (UI) in the context of digital transformation.

An innovative external baggage storage system for public transportation has been developed to ensure the ergonomic requirements. This paper proposes, for this system, a user interface that increases the level of comfort and security for train passengers. The interaction between the storage system and the final user it’s based on a complex scenario which includes the analysis of train stops time frames, type of luggage, train station configuration and the user’s age..

The system described in this article has been developed within the consortium of project FANCI (Face and body Analysis Natural Computer Interaction) project. One of the main scope of the project is to give a better support to the driver’s capabilities using some of the most advanced technologies in the field of intelligent user sensing methods, including eye tracking, face analysis, emotion recognition, intention & authentication, voice tone analysis, hand gesture recognition and head gesture & pose analysis. All these technologies will be integrated in a unique platform which is always-on, real time, low consumption and low cost. The information collected by this platform will be used as input of smart user intention or distraction estimation and system reaction methods, supplying visual (HUD, etc.), voice and haptic feedback as well as autonomous system actions.
