The First Haptic Wrist Band Design

In 1995, inventor Geir Jensen designed a piece to mount on a watch strap that could provide caller identification through haptic rhythms. His device was based on a frequency-controlled actuator that provides tactile feedback, but he never actually built the hardware. Instead, he submitted the idea to a technology competition and was rejected by the Norwegian Industrial and Regional Development Fund. Jensen was thinking two decades ahead of his time.
