controlled through a translational reality interface.
A Translational Reality Toaster
To illustrate a translational reality interface in action, I
chose a toaster because it’s one of the simplest, cheapest,
Key components include
an Arduino Uno
microprocessor, a 4131 digital
potentiometer, a soil moisture
sensor, a toaster, and a water
pump with controller (see
Translational reality is a real
time closed-loop system in
which a user operates a
familiar first device and, in so
doing, both monitors and
controls a second device.
User feedback is appropriate
to the first device, but reflects
the operation of the second
