The term "glanceability" refers to the most important principle in designing wearables with displays. It means that wearable devices should be designed in a way that users can understand what's going on with just one glance or interaction with them. Glanceability is less about reducing the amount of content to its basics on a screen and more about researching user needs and finding out what information they would like to see at specific moments.^[1]

Unlike smartphone or tablet interfaces, wearables are not meant to hold a user's attention for long. Users want to spend as little time as possible interacting with them and prefer not to scroll through content. Additionally, people often use wearables on the go — while jogging, exercising, commuting, walking a dog, or shopping. The goal is to help them instantly access the information they need and continue with their activities.
