The Rock Band 3 Squier Stratocaster uses technology built into the neck and fingerboard of the guitar to track finger positions
in real time.
The rubber-covered casing with useful impressions in the finger positions
is especially tactile and makes them really comfortable to hold.
Dynamic fretboard that shows finger positions
synchronized with the scrolling music notation (lefties can invert the fretboard)
Display a fretboard (for any fretted instrument with 4 to 7 strings) or piano keyboard that shows finger positions
Capacitive solutions such as Synaptics ClearTouch use a grid of conductive traces implemented on a clear substrate such as polyethylene terephthalate (PET) film or glass to accurately report one or more finger positions
and relative pressure on a sensor.
The games include the single player Rocker's Challenge - where players try to strum to the built in lights while matching the finger positions
and play through the complete song; the multi-player Shredder's Tourney - where up to 4 players are challenged to compete and play a section of the song; and Blast Jam - where players have full control to create their own jams.
Finally, it's time to put all that practice and hard work to the test in step three, incorporating strumming and finger positions
with both hands, just like a real guitar.
