About the Mir API, I asked greyback before replying to your previous comment, and he confirmed we don't have a reliable way of representing physical sized, for example on a projector the size will be 0x0.
One of the reasons we have the GU is to represent "more or less" the same physical size everywhere, so I think we don't have any other choice here... -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to unity8 in Ubuntu. https://bugs.launchpad.net/bugs/1468645 Title: [sdk] Buttons and other widgets are too small for comfortable touch usage Status in Ubuntu UX: In Progress Status in unity8 package in Ubuntu: Incomplete Bug description: [Updated description] On Ubuntu phones, buttons and other widgets are too small for comfortable touch usage. This is mostly about buttons like those seen in the shutdown dialog. They feel too small (they are in fact 5.5mm high) to be able to reliably hit with a finger, and that's on arale which has a large screen. But our GUI elements vary in size a lot and we got it right in the many menus/list views. There, each row is a nice comfortable height (10mm). Compare to Android 5.1.1 on a hammerhead where buttons/list items are 12-15mm high, the larger size is more comfortable and faster to use. ––– Update: The shut-down dialogue will follow new rules we are defining for button size and spacing which will appear with updated SDK UI items. The GUI elements should all be touch friendly and consistent in size.
