VINCENT
Vincent is a chair. A chair who refused to treated like a static and unfeeling. Vincent is not a regular chair, you can stay close from him but not sit on. Vincent is chair with who you can communicate, speak during hours.
The Vincent project is an experimental research of interaction between man and object. We have trying to express emotions across a chair, to create a real connivance. We have thinking about different interaction with the object (tactile, oral…) thanks to differents sensors. We have trying to create his own language with littles motors or vibrators, using the acoustic of the wood or the little piece of metal to find different kind of speach (friendly, formal, unhappy…).
Video: Presentation of Vincent
++++++++++++++ BRAINSTORMING ++++++++++++++
After we find the idea, the most important what to determinate the best place on the chair for the interaction.
++++++++++++++ EXPERIMENTATION ++++++++++++++
We have experiment a lot of different system to make some noise, sound with motors, vibrators, sometimes by using a makerbot to print some piece, like a screw.
++++++++++++++ BUILDING OF THE CHAIR ++++++++++++++
Video: Vincent say hello world
++++++++++++++ BUILDING OF THE CUSHION ++++++++++++++
We have use a red fabric to screen printing on it black thermochromic ink. The system use to heat the ink is a pattern sew with conductive thread, which when we put electricity inside is resistive so the thread heat up and let the pattern appears on the cushion. The idea for the cushion was to imagine it as a part of vincent so when you want pull it out is like undressed vincent so the cushion start to blushing.

++++++++++++++ CODE ++++++++++++++
++++++++++++++ DEBUG (a lot) ++++++++++++++
++++++++++++++ FINAL PRESENTATION ++++++++++++++
++++++++++++++ TECHNICAL PART ++++++++++++++
For sensors, we have use capacity sensor, perfect for feel different move and caresse with.
