Design Rationale

The following short list gives you an overview on important observations and influences that affected our design process:

1. Came up with initial idea of the glove: Fingertips connected to port-pins, thumb providing voltage, items conducting.
   reason: This design would be easy to build and use.
2. Learned about the Teleo module and RFID chips, decided to use Teleo and RFID: Identify items with RFID chip, use Teleo module + USB port.
   reason: Items don't have to be conducting, MAX/MSP is available support for Teleo.
3. Put force-measurement into account, saw a RFID reader for the first time: Now the force with which is pressed affects the volume, except thumb, that works binary; not quite decided what thumb does now that it does not only provide voltage, i.e. tells us "item is picked/not picked"; reader supposed to be put on the back of the hand.
   reason: Force brings in more flexibility in our glove, thumb probably will, too. RFID reader easy to maintain.
4. Decided to use thumb as octave-offset, decided to put second glove over first: The thumb now is supposed to work like the octave-flap on some instruments, the cables on the so-far build glove will be protected by a second glove.
   reason: Some items can be held without the thumb, an octave-flap correlates with many real instruments and doubles the range of notes. The cables on the glove are protected from accidental pulling.
5. Had to build RFID reader into the palm rather than on the back of the hand.
   reason: the signal got jammed by the hand
