Hygiene Elevator / Elevator

Hygiene Elevator
Hygiene Elevator

Hygiene is always an issue, especially for hospitals. Buttons in elevator are one of the places where germs and virus were exchanged most frequently. While elevators are mean to increase mobility, hygiene of the buttons tends to be neglected. Furthermore, it has become common curtesy to hold the doors open for others, which somehow enhance the opportunities of indirect contact in conventional elevators.
Hygiene elevator uses projection and motion detection, so that users can select destination with their feet. The awkward moment that almost been held between doors can also be prevented since everyone passes the open button while leaving.
