The Hat

This "Smart Hat", which we've dubbed "The Hat" for this project, was designed to relax the chef during his or her moments of “lull” (as monitored by The Signal).

The hat is a bit on the whimsical side. The motor and head massager will be fixed inside a slightly elongated chefs hat. An additional fan will be fixed within the inside of the hat to avoid disturbing any delicate plate presentations the chef might be working on.

Both the fan and the head massager are triggered by biometric indicators of stress (currently a soil moisture sensor) and moments of high workload (triggered by The Signal), which allows for a moment of relief when there is no time to take a break.
