I'm developing a Windows Phone 8 app where all the pages are in portrait orientation. I have the problem of designing/porting this kind of a GUI to smart phones:
The comboboxes on the left represent boolean operators, the comboboxes on the right represent various fields (person's name, surname, address...), the middle textboxes contain keywords.
So, I came up with this:
Do you think this UI is understandable for the non-technical folk of the internets? Do you have any suggestions on improving the design?
