There are lots of techniques out there to solve input problems. The less controls you have, the more specific you have to be in your software to help user. For example, if you have knowledge to avoid user entering details, then better. That involves thinking case-by-case. Providing choices is always better than letters. Applying dictionaries, rank options (initially per language, later by user common choices)... Last but not least, consider linear input instead of circular for on-screen design. The circular was a physical limitation. You do not have that anymore, no need to replicate that limitation physically. People often do some things like: <-[opt1]-[opt2]-[opt3]-> with every option readable but opt2 having a clear highlight. You can fit more than 3 options if screen size allows. If you follow that we have a widget called "diskselector", it's ugly in the default theme,but you can work around that with some designer :-) -- Gustavo Sverzut Barbieri http://profusion.mobi embedded systems -------------------------------------- MSN: barbi...@gmail.com Skype: gsbarbieri Mobile: +55 (19) 9225-2202 ------------------------------------------------------------------------------ This SF email is sponsosred by: Try Windows Azure free for 90 days Click Here http://p.sf.net/sfu/sfd2d-msazure _______________________________________________ enlightenment-devel mailing list enlightenment-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/enlightenment-devel
