A few weeks ago, I acquired a Myo armband. Myo is a muscle-movement sensor worn around the forearm. And on the basis of a series of hand gestures, the person wearing it can control anything from a slide presentation or a cursor to an r/c car or drone. You can read more about it and watch some neat videos of it in action on the Myo website.
As an input device, it takes some getting used to. When I set it up to control the cursor I found it so difficult to use that I almost immediately resorted to using the trackpad.
And here is where the interactivity clutter became obvious. A quick note: interactivity clutter is a term coined by Lars-Erik Janlert and Erik Stolterman to describe possible consequences of the increasing number of (co-existing) interactive artifacts in our environments. This definition doesn’t do justice to their work but it suffices for my purpose in this post. You can read more about it and get the citation information here. I will just finish telling my story to illustrate a simple way clutter can impact daily life.
I was wearing the Myo around my right forearm. And I was the using my right hand to manipulate the trackpad. The cursor began shakily darting around the screen in response to the slight but apparently detectable tension created by the direction of my arm/hand movements and my finger movement on the trackpad. I grew frustrated and a little more stressed than I had been moments ago, and I took the Myo off of my arm after several failed attempts to expand a ‘file’ menu.
I shudder to imagine what would have happened if I had tried to use the wireless mouse…
