Understand use cases
When designing apps for smartwatches, focus on use cases that make sense for the watch environment. Watches allow users to get information at a glance, such as the arrival of the next bus, and to act quickly, like responding to an instant message.
The watch interface presents unique usage opportunities that are not available on traditional mobile devices, including:
- Easy access (with a flick of the wrist)
- Input enabled by a physical body connection (through sensors, motion detection, and buzzing)
The watch also comes with limitations:
- Smaller screen space
- Less information density
- Limited battery life
Consider both the capabilities and limitations of the platform when designing apps for watches.
