In a Q&A session during the Windows Phone Design Day in Stockholm,Â Petter Silfver, Interaction designer questioned Microsoft on why Windows Phone app bar icons have circle around it. He even did a blog post claiming Microsoft’s inconsistency in design and made some interesting points on why the circles around the icons should be removed. You can read his post here.
Here is the Microsoft’s response to his claims from Arturo Toledo, UX Designer at Microsoft. Microsoft has two graphic things in their design, icon buttons(circled) and icons.
We use icon buttons for enabling interactivity and icons for communicating a message one-way.
For example, the out-of-the-box phone app uses icon buttons with a phone icon next to the calls in the call history list – these are buttons, not icons.Â Another example of the use of icon buttons, in theÂ text messages app – when you want to add a new person to send a text message you get a little button with a plus sign iconÂ but again, this is a button – not just an icon.
We use icons as graphics thatÂ provide information to the user one-way (they are not interactive, thus not buttons). Â For example inÂ the status bar theseÂ are truly notification icons and they do not use a circle (they are not buttons).Â For example in the email app we use little icons (not buttons) toÂ communicate toÂ the user that thereâ€™s an attachment in an email or that thereâ€™s a high priority email (flag).
