New page

So this idea is still in the rough exploratory phase. What I'd like to have is a way to input text that:
* can be used anywhere and doesn't require a surface to work with.
* doesn't require radical rearrangement to engage in normal activities (picking things up, etc.)
* isn't particularly difficult to learn how to use.

Ideas
* it sounds like a pair of gloves would would make the best armature
* I'd ''like'' a full qwerty keyboard, but finding that many finger positions would be difficult.
* with 4 fingers on each hand, it conveniently translates into some nice binary mappings.

Switches will probably be the limiting factor for functionality. I've been looking at a couple of different types:
* reed switches
** Pro: clear activation, relatively easy to actuate
** Con: made of glass, kind of long and large for a fingertip, not terribly cheap
* tactile switches
** Pro: Really cheap, small and discrete, clear activation
** Con: hard to actuate, hard to connect up
* roller ball switches
** Pro: clear activation, unique operation
** Con: much too large for fingertips but may be used in back of hand.
* Conductive fabric (homemade) switches
** Pro: very discrete, entirely appropriate for gloves
** Con: no activation feedback, potentially questionable/finicky contact.

If we can connection controls in, we can repurpose a keyboard USB adapter to connect up with the outside world. If we decide to go with a chord-style keyboard, we'd have to come up with a translation mapping to the keyboard-usb inputs. Maybe some reverse charlieplexing or something?
