## Background
TECHNICAL FIELD
The present application relates generally to extended user input. The present application relates particularly, though not exclusively, to providing of natural and intuitive gaming input controls on retractable portable devices.
BACKGROUND
Various portable electronic devices have user interfaces to enable interaction with a user. The user interface of portable devices is often a compromise between mutually conflicting design objectives related to cost, complexity, accessibility, intuitiveness and compactness. Mobile phones typically sport a display and one or more keys on a common side so as to enable displaying of information and input of data from the user. The display may be a touch display in which case fewer keys are needed.
Some mobile phones have a clam-shell form factor in which the phone when opened reveals on its two internal walls a display and keypad, respectively. Another form factor is a monoblock model in which there is a display and some keys which occupy most of one side of the phone. There are also slide phones with a user interface that is extended by sliding apart a display part and a keypad part.
Game controllers of different game stations are specifically designed for comfortable grip and access to controls. Such controllers typically have an arcuate form and such a size that they suitably fill the hand when gripped by a user. However, the game controllers' design makes their placing in the user's pocket difficult or impossible. There are also some mobile phones designed particularly for gaming, with keypad arrangement on a front surface around the display so dimensioned and laid out that the user should be able to reasonably access the keys.
