Assistant SZ is an application for smartphones and tablets using Android that recognizes obstacles to the movement of a pedestrian and warns him about them. The Assistant SZ detects obstacles using the smartphone's rear camera only when the pedestrian is moving and their smartphone screen is turned on. In this case, the pedestrian can use any basic app they need at the moment. This helper application recognizes pavement curbs, warning marks (yellow lines, luminous bands), lampposts, road signs as less dangerous obstacles. At the same time Assistant SZ is able to identify the most serious dangers that can cause irreparable damage to the health of a pedestrian: crossings; train, metro and tram platforms; stairs. The app warns about a hazard in several ways and has flexible settings: an icon in the taskbar notification area; vibration of the smartphone; sound notification; text message on the smartphone screen.
