Don’t open the door.

Doors are designed to be opened one way, or both ways, which may result in accidents.
Users may push open the door without noticing others behind it and hurt them. A see-through window can be used on the door; yet, the issue of privacy is another important thing to be considered.
To solve this problem, we invent the sensor carpet to inform the user that there is someone behind the door. When a user steps on the carpet on one side, the carpet on the other side illuminates light and gives cautions.
