http://wiki.tcl-lang.org/taipudex+lookup describes a lookup method called taipudex and links to an AndroWish demo app.
On small mobile devices big buttons help with button-press events. The app provides a fullscreen virtual keyboard that recognizes tap and resize events (Android rotation or ChromeOS). At the same time it is usable with direct keys, that is without the need of modifier keys.
The method basically supports automatic prototype layout of industrial control panels or interactive exploration of any data.
Feel free to spread the Android app and suggest to users with visual and haptic difficulties.
