A transition is definitely taking place in the way we interact with electronics. We are moving form using keyboards, mice and graphical user interfaces to using voice, touch and gestural movement. How will this impact medical device design, and what do we as designers need to be aware of moving forward?
Remarkably, touch capacitance works through surgical gloves and sterile plastic overwrap. This article, How to use an Ipad in the OR during surgery has some interesting observations and thoughts.
More than touch and voice, I see gestural control as being the desired method for many medical device applications. Imagine coupling gestural control with haptic sensing/feedback technology. That is where things are headed. Beyond that, the next step will be controlling devices with our thoughts alone.
