In order to enhance interaction between the chef and the customer, we tried to design devices for customers to express their appreciation to the chef as well as soothing chef's stress doing the same thing all day. Our device should be more ambient and fits into the setting of Chinese Dim Sum restaurant.
Dim Sum restaurant's kitchen may be different, but two things are always the same: steam everywhere and steam baskets stacking all over the place. This makes the lack of vertical space for chefs and they spend most of the time busily on the little preparing tables.
When the customer knocks on a particular point on the table, this device on the chef side creates an image on an acrylic sheet out of steam to convey to the chef that he/she really appreciated the food. On a level below this, we have moving lotus floating on water which gives a glimpse of a traditional Chinese pond to relieve the stress of the chef after a long day's work.
