Instead of having to physically touch the buttons to pick the floor you're headed to, the only thing users will have to do in this elevator is hover their finger over the holographic button representing their intended floor. The cool thing about this feature is the fact that the corresponding physical button on the elevator will also light up, indicating a 'press'. It was installed on August 1 as part of a trial by a company called First Step Elevator. But here's the kicker: a single unit can cost anywhere between US$4,362 (S$6,000) and US$6,544 (S$9,000). It depends wholly on the amount of buttons that need to be displayed. But what if the holographic buttons fail? Well, that's why the physical buttons are still there, in case of any emergency. This also helps it abide by regulations set out by the Building and Construction Authority (BCA). First Step Elevator plans to introduce the holographic module to more office buildings in the future.
