1. Realizing the possibility of action - a lifting and transport device that transports elevator passengers or goods in a vertical direction along rigid steel elevator rails

2. Device tags - The button which calls the lift to your floor.

3. Mapping -  The display and arrows under the lift show the location of the lift.

4. Feedback - The lift will move to your floor.

5. Rating: average design. 2 points out of 3. Simple design, with one button instead of two that indicate in which direction you want to move. There is no Braille notation that helps the blind to find the button.
