People with eye problems are restricted in movement. They have difficulties walking along the streets and visiting public places, including stores, shopping malls, and railway stations. To help people with limited mobility and improve quality of their lives, many companies implement into their infrastructure innovation technologies, such as indoor navigation for the visually impaired and the blind. The platform is based on the precise localization technology and helps users to navigate around buildings.

There are numerous data sources that can be used for navigation, including GPS, WiFi, Bluetooth® LE protocols and many more. Among them is inertial navigation, one of the most precise sources of information for indoor positioning.

In the face of the Covid-19 pandemic, working place safety is an important issue for enterprise managers. Nowadays many companies are searching for the most effective solutions that will let employees return to normal work without any risk of being infected. Bluetooth® contact tracing is one of such solutions. The technology allows tracking the movements of the staff during the day and, if necessary, easily traces the interaction of the infected person with other employees and finds the places where they have been since the time of the first symptoms.
