4-quadrant modus

The «4-quadrant»-function on the ticket machine was developed specially for persons with visual impairment. In the 4-quadrant modus the ZVV-machines display the tickets with the most sales in the four corners of the screen in an amplified font.

The 4-quadrant modus displays those four tickets which have been sold most at the location concerned, in an amplified shape in four quadrants. Along with the 4-quadrant display, on request the text displayed is also announced via audio.

Activation

Switching to the 4-quadrant modus happens via three concealed buttons which are not visible on the user display, by touching which an action is executed.

  • Up left: Full-price sale
  • Up middle: Language selection
  • Up right: Reduced price sale

The desired display is activated by tapping the area concerned once.
