Touchscreen arms

At a fi rst glance, the Cicret – which is pronounced
“secret” – looks just like any standard fitness
band, but with just one twist of your forearm, it
reveals its biggest secret: a picoprojector casts an
image of your smartphone’s user interface
directly onto your arm, turning your skin into a
touchscreen! An array of eight long-range
proximity sensors tracks the position of your
fi nger as it refl ects their laser output. Cicret
works on all skin colours, and even works in
bright daylight too.
