Future interaction 

1. We think about why would someone want to use it for a prolonged period, would they outgrow it? Therefore, we propose to add a level of abstraction to our interaction design leaving it to the users to define their own way of expression. 
2. Maybe they might want to send a code using the frames, BRB (Blue Red Blue = Be Right Back) 
3. Another expression like - holding to the frame for longer : Making the LED flash for 5 second could relay that "5 seconds not being with you feel like 5 hours".
4. We also thought about the moment in time when the recipient is away and not getting informed about the interaction at all. Right now we are debating how to relay that information, or may be not relay at all.
