Here is a very innovative approach to providing a user guide, from Samsung :
According to Vitamin Design:
These books actually contain the phone. Each page reveals the elements of the phone in the right order, helping the user to set up the sim card, the battery and even slide the case onto the phone. The second book is the main manual – the phone actually slots into this and becomes the center of attention. Arrows point to the exact locations the user should press, avoiding confusion and eliminating the feeling of being lost in a menu.
It’s a interesting example of user documentation as an emotional experience. (Thanks tofor spotting this.)
