Hi all, recently I noticed what I consider a couple UI defect present on all OS I know. Both are about providing user feedback.
The first one concerns the copy operation. This operation provides no feedback at all to user. You cannot know if you pressed correctly the keyboard shortcut, if the object can be copied and so on. I often prefer to use a cut followed by a paste/undo to be sure of the operation. The system should provide some feedback for this: the selected part could blink a couple of times and for the failure of the operation a red border could blink, or something like that. The second one is about double click. You cannot know if you did the two clicks or a double-click. If you are too slow you just stay there staring at the selected icon. This is sometime a problem for non-expert users. A tipical scenario is application launch from desktop icon: you cannot know if the app is starting so the app has to provide a splash screen to give feedback to the user when the real problem is the double click operation (a splash screen is of course useful for very long startups). Let me know what you think about this. Bye Lorenzo _______________________________________________ Usability mailing list [email protected] http://mail.gnome.org/mailman/listinfo/usability
