Availability: Early 2017 OUR MOBILE devices communicate with us through sounds and screens, but a new wristband relies instead on touch. The device, called Moment, vibrates to convey information. While phones and smartwatches can send an alert by vibrating the entire device, Moment uses four motors to allow for different types of haptic feedback depending on what it is trying to say. Instead of glancing at your phone’s screen every time a new GPS direction comes up, imagine having an arrow traced on your wrist. For app, text, and other smartphone notifications, the device can assign different tactile patterns to different contacts.
