What Problem Does This Solve?
Show objects that are in close proximity to your current location.
When to Use This Pattern
Notify users that someone or something is close to them. Analyze the users’ current location and show people or objects that are near him/her.
What’s the Solution?
Nearby is technically speaking the result of a buffer operation but without the Buffer interface to enter the distance. It is the job of the application design to determine the logic to buffer specific layers within a specific distance of the users’ location and decide on how to feedback this information.
Why Use This Pattern?
Users have a deep interest to know what is happening around them. Showing them the location of nearby objects has therefore immediate impact on decisions they may want to take, e.g. if a friend is nearby they may want to message them to meetup.
- The Nearby pattern can be invoked implicitly (alerts or notifications) or explicitly (button click) to determine results based on predefined layer and distance parameters.
- Different to the buffer pattern the user is not given the opportunity to change these parameters.
- In the case that the meaning of items displayed on the map cannot be inferred through map markers and labels alone, it can be necessary to accompany the map with a list that directly references the nearby elements
