Active broadcast of presence
Users may choose actively when they want to share presence information, to increase both the relevance of, and control over, sharing.
Enable sharing of location or presence data where the user controls the timing and context.
When a user wants to share or broadcast location or other presence data that is contextually relevant and a full stream of data may be either noisy or intrusive.
How can a system broadcast a user's presence or location information to a social network without revealing sensitive locations or location histories or overwhelming recipients with noisy data?
Always requiring active decision-making can burden the user with choices.
While sharing access controls may allow constant access, only broadcast presence information at the active choice of the user.
