This month, we aim to explore the full potential of the smart display modules from 4D Systems that we introduced in the March
2013 issue. Last time, we became oriented to the
smart LCD and OLED modules, and created a
simple face using the Visi interface. This time, we
want to add some expressive range to the robot,
and we wanted to coordinate the expressions on the smart
modules with sensor input from the robot.
Could we integrate the smart modules into a robot so
that both the screens and the bot responded appropriately
to stimuli? Would the components co-exist peacefully as a
harmonious symbiote, or hopelessly clash like Frodo’s
goodness and honor and the seductive power of the One
Ring? Just like a Hobbit breakfast, all of this would be
wrapped up in the second installment.

Who's Afraid of the
All Seeing Eye?
The smart modules from 4D Systems are meant to add
an artistic flair to existing projects or even act as a stand-alone unit. The smart modules — which come in both LCD
and OLED flavors — are equally comfortable as passive
displays or interactive gauges.
The most intuitive interactive applications involving the
smart modules, however, mostly involve just the smart
module and some sensors. The touch screen modules in
particular have built-in objects like sliders and buttons that
allow users to interact with the module through the screen.
