Movement and informing visually impaired persons is difficult because mobile application solutions and services are unable to work in indoors environments (location based service using GPS technology). Main precondition for active participation in the daily living and needs of visually impaired persons is increased degree of mobility. The aim of this research is to increase the quality of life of visually impaired persons and the degree of mobility in indoor environments by applying modern information and communication technologies (Cloud Computing, Fog, IoT, AAL / ELE platform). User requirement will be used to define functionalities of service for informing visually impaired persons in the example of large retail chains. A conceptual system architecture model will be proposed for providing information service with the aim to provide real-time information to users. This research will also show simulation testing of the proposed architecture with Arduino Uno and Raspberry Pi 3 platforms for collecting information and informing end users. [ABSTRACT FROM AUTHOR]

The information about the environment and the precise guidance of visually impaired people is the basis for their safe movement of the traffic network. Therefore, the information and communication services should be adapted to this group of users. The services based on the advanced information and communication technologies provide the visually impaired persons with information about the environment while moving along the traffic network. This paper analyses the currently available information systems of users when moving traffic network, and the currently most services based on new ICT (Information and Communications Technology). The analysis was carried on a representative sample of the City of Zagreb (Croatia) in involving all interest groups of visually impaired people. Based on defined user requirements is proposed a new services based on NFC (Near Field Communication) and RTLS (Real-Time Locating Systems). Testing and analysing the efficiency of single information and communication technologies have been performed on the actual traffic network system of the City of Zagreb. The users of the Croatian Society for Promotion and Development of Tiphlotechnology (Hrvatska Udruga za Promicanje i Razvoj Tiflotehnike–HUPRT,http://www.huprt.hr) participated in checking the efficiency of single technologies and services.

The movement of the blind and visually impaired persons in the traffic network is today based exclusively on the application of aids (white cane) and methods that the users learn during the training of orientation and movement. In present paper authors investigate accessibility of information and communication technologies and services with the purpose of increasing the mobility level of the blind and visually impaired persons when moving in the traffic network of the City of Zagreb. The traffic intersections were analysed from the viewpoint of difficult-to-master for independent movement by using the basic methods of crossing a traffic intersection which the users acquire at the training of orientation and movement. The method of survey and interviews with a target group of users was used to evaluate all the relevant parameters of guidance and navigation resulting from the mentioned analyses and by performing training of orientation and movement in the duration of six months. Based on the carried out research and the used scientific methods the dynamic model has been defined and it is based on relevant parameters of guidance and navigation, and on the application of the information and communication technologies and services. The information provided to the user, by the system, is defined according to the currently available technologies. The model was efficiency tested on a real system of the traffic network of the City of Zagreb. [ABSTRACT FROM AUTHOR]
