A possibility to provide an artefact beside the documentation of the project could be the use of designer toys. They come in many variations but always in simple forms. Easy to adapt and also possible to paint them yourself.
With the CX70 Emoty feelings, emotions and moods can be expressed in a quite new way. Laura, Joey and Wobble are chracters who “live” on your mobile phone and who can express ten different kinds of feelings. By pressing keys on your mobile or through special sensors on the phones case you can control their feelings and let your friends know in which mood you currently are.
This project also reminds me a little bit of Tamagotchi in respect of a little creature “living” in a portable device and expressing feelings. However, the crucial difference is that the Siemens Emoty can’t develop feelings of its own, but only reflects what the user tells him to feel. Laura, Joey and Wobble won’t change their mood an their own, won’t get sad because of not being cared for, won’t die.
