With a simple two finger tap gesture users are able to share their availability throughout the day with their partner. The surface turns into a switch form allowing them to change their status from available to unavailable throughout the day. If both user's are available the surface will ripple and send out small haptic vibrations. Even if it's just 15 minutes after a meeting both users are notified and can find the perfect window to chat.
This features doesn't change they way we talk, but instead when we talk. This creates a relationship with less stress and pressure to plan and more spontaneity. No phone tag, no fragmented texts, but instead small windows of meaningful conversations.
