Many people go out of their ways to touch as little as possible while in public restrooms; an invention like the Foot Latch would certainly reduce hand contact with unsanitary surfaces. Just as you might prefer to activate the toilet flusher with the sole of your shoe, so would you use this same technique to open and close your cubicle.
Behzad Rashidizadeh's design requires installation along the bottom of the door, where it meets the adjacent partition. A small but sufficiently broad pedal would be accessible from the inside, enabling you to easily depress it once you've completed your business. The metal Foot Latch has rounded corners and would not become an inconvenient catch for coats and bags. It moves easily with the help of spring hinges and keeps washrooms a touch more hygienic.
