User Story: Current Location as a Direction

Goal

Individuals should be able to express their current location not only as a spot in place, but as a direction as well.

Summary

In many Social Web sites, users can declare their current location (e.g. Paris, New York). This can be useful for their friends to localize them. When a user posts some content (e.g. a microblogging post) the location can serve to enable better understanding of the content in the context of the current location. However most services limit the declaration of location on a particular spot in space (a latitude-longitude couple) and in some cases what is relevant is not the exact spot but the direction of the user's movement. Like in situations where user is on a train to a certain destination; where the exact spot where he/she is at the time of posting some content might be far less relevant than his/her direction of movement. On the other hand, when users are on the go; their direction of movement might be available on train/bus/plane ticket selling websites. Users should be able to import this information in other applications and integrate it in their daily experiences.

  • After writing a micrbolgging post her application offers her to publish her location in different forms like: current spot (latitude, longitude) where the train is at that time; or direction ( from Paris to Nice).
  • According to the nature of the microblogging post content Alice chooses the most appropriate way to disclose her location

Alternative paths

  • The microblogging application might have obtained the information about the direction from Alice's calendar as well, provided that she has previously entered the trip data in her (mobile or Web-based) calendar.
