Embedded + Wearable: “Homing Device” by Chris Williamson (2014)
This “Homing Device” is a belt containing a series of small vibration motors which allow it to give a strong directional sense to the wearer by vibrating whichever motor is pointing in a particular direction. This means the belt can essentially act as a persistent compass, its direction available to the user at all times, even unconsciously. Rather than pointing north like a normal compass, however, the user programs it with the location of their hometown and it always points there.
