The thesis of Ana Camila Amorim... Almanaco Portrait surely deserves attention! When communication stops between individuals, does the element representing it shrink?

"Idea/problem/context: Communication is part of human nature - an ever-present interaction forming bonds between people. The expansion of information and communication technologies and the mobility and miniaturization of devices has resulted in an always-on connectivity - anytime, anywhere. This blurs boundaries between work and play, and between our public and private lives. Because others have little awareness of our context, we are often confronted with situations of abuse or unwanted interruption.
The primary goal of this project is to expand the currently limited repertoire of signs to actuate and support non-availability. Users define their visibility at each moment, allowing granularity of access depending on their social relations and context."
