Abstract
A mobile phone has several buttons/keys e.g. numerical keys, side keys, camera buttons and navigation keys. SEMC, Sony Ericsson Mobile Communications AB, has mainly used the joystick and the rocker key as their navigation devices since they released their first phone in 2002. These technologies are used in all their phones except smart phones, e.g. W950 and P990. During the years SEMC has experienced some quality problems with their navigation devices, mainly with the joystick, because of the lack of ability to keep dust out. As the development of mobile phones progress, with more functions and larger quantity of data to go through, the need of a navigation device with more possibilities arise. The purpose of this master thesis was to perform a pre-study on the next generation navigation devices for mobile phones and based on that give recommendations to SEMC of which navigation devices suitable to be used in the future
