Elderly Challenge - Observation 2

There are lifts in HDB flats that benefit the elderly, so that they do not need to take the hassle of using the staircase to go up the building. The lift buttons have brail that enable the visually handicapped seniors to press them.

A similar application is also in the MRT Stations where the floors have something like the brail that helps the blind walk and find their way to the MRT Platforms and MRT.
