Neonode N1 is perhaps the first smartphone where the idea of touch control stilus by finger was introduced. The Swedish company of the same name Neonode developed for this smartphone a special interface "Neno" supporting the control technology using the thumb. However, Neonode N1 wasn't widespread, only two models N1 and N1m were produced. The differences were only in the newest operational system and advanced camera in the model N1m.
