Smartphones represent a relevant factor in accessing information and communication networks. The number of new ICT services and applications is continually growing. A wide population of users having different user demands is using smartphones in their everyday life.
The key objective of this research is to analyze possible scenarios of smartphone usage and the usage of related ICT services depending on the different smartphone user groups.
Main predicted costs are related to development of the supervisory measurement system made of sets of smartphone devices and applications for tracking user’s behavior, and the application for processing collected data.
The expected scientific contribution is the establishment of the new model for identification of user’s behavior and prediction of user’s future behavior. This model will contribute to the development of human potentials and to better equipment of devices according to the specific user needs.
