Smile Key

IF Concept Design Award 2013

 Joyce Chu / Pong-Cong, Yu

Using the intuition of the shape and direction of how our hands grab keys helps us distinguish and open doors in dark places. A substitute of touch instead of sight may allow people grab keys in dark places, convenient for women coming home late and the blind.

Smile key is shaped as a smile, fit just right for fingers to touch. When we want to open a door, we have to search for the needed key from a pile of keys and memorize which key matches which door.
