Touch - teases and transitions WinPhone7
LukeW explains this: While the Windows Phone 7 Series user interface may not be optimized for high information resolution, it does make interesting use of teases and transitions as highlighted in the video below.
Because it is a touch-based device, the Windows Phone 7 Series uses a Natural User Interface (NUI) paradigm that turns actual content into interface controls. NUIs frequently need to let people know what elements are interactive. (Ideally everything is interactive in a touch-based UI but that's a different point.) NUIs should encourage exploration and give people "permission" to touch things. Teasing people is one way of encouraging interactivity and exploration. Se the resto of the article here.
