Now we get to my personal favorite. The idea is based on watching my father and father-in-law during a long period of convalesce during which they were weak and bed ridden. I’m bringing it up here more or less to possibly network with other possibly interested in the same. The essential insight is this. In each case their worlds become smaller and smaller. As they become weaker and weaker, the effort both physical and mental, required to do such things as even pick up a smartphone let alone a tablet become too much.
There’s this wonderful phrase in usability engineering “cognitive friction.” If you think about pushing something on a surface, there’s resistance due to friction. As you get weaker and weaker, eventually you can no longer move the object. Using computers also requires effort, and cognitive friction is a metaphor resistance to their successful use. Earlier I spoke of minimizing time between intention and action. That’s also minimizing cognitive friction. Even a small amount of cognitive friction can completely stop you if you are weak or distracted enough by pain or drugs.
In this slide we see the Glass configuration screen, that allows you to set the angle above which the Glass micro display automatically turns on. I’ve experimented and you can get the interaction between this set angle and your own position so that virtually imperceptible movements of your head can turn Glass on and off. So I imagining seeing Glass to, say, pull photos of the family from an online service, but to only do so when you head is moved to a certain position, or perhaps to a certain position in conduction with a head gesture.

Including this somewhat technical tweet, because it’s about using Glass to control things (lights, temp, etc) in your home. So relevant to enabling the bed-ridden.
