Mediating social relationship through mobile communication within groups of teenage girls

Ruth Kikkin-Gil's masters thesis seems nice. It's about "mediating social relationship through mobile communication within groups of teenage girls".

The extremity in teenagers’ attitudes and actions coupled with the opportunities of mobile communication, creates new behaviors and re-shapes existing ones. But however meaningful the phone is in teenagers’ lives, it is not designed to support their need for emotional communication and group identity.

The BuddyBeads project suggests alternative ways for communication among teenagers, ways which emphasize their social structures, behaviors and needs. BuddyBeads are techno-jewelry items that facilitate non-verbal and emotional communication among group members, through codes and signals which the group decided upon together. Each group member has a matching jewelry piece and can use it to communicate her emotional state to the other group members. messages are decided by the group in advance and construct a secret private code among its members.

I would be interested to see the results of the user-testing, like how could private codes emerge, how they are used or made of. In addition, I am curious to know how external persons perceive this or how they get what is happening. The disruptions created by tangible/ubiquitous computing is important and some people does not even notice that some stuff (like non verbal communication in this case) is happening.
