Abstract
Problem statement
This thesis work was initiated since there are problems with the navigation
devices currently used by SEMC, Sony Ericsson Mobile Communications
AB. The problems with the currently used navigation devices are lack of
ability to keep dust out and they don’t meet the demands from future
applications like scrolling through large amounts of data, image editing and
advanced web browsing.
Purpose
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.

Problem statement
This thesis work was initiated since there are problems with the navigation

applications like scrolling through large amounts of data, image editing and
advanced web browsing.
Purpose
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.

Method
A state of the art was conducted to establish the needs, survey components
among different manufacturers and existing products on the market. Initial
target specifications were established based on the information from the state
of the art. The components from the different manufacturers were rated and
ranked according to the initial target specifications and six components were
selected for further work. These six were evaluated according to technical
target specifications and demo kits from the different manufacturers were
used to conduct a usability study. Finally the components were evaluated
using the result from the initial target specifications, technical target
specifications and usability study to select two components to be
recommended to SEMC. Recommendations of further work are also given.
Conclusions
The usability study showed that there is no need to select a fully analogue
navigation device in front of an 8-way navigation device. The 8-way
navigation is accurate enough for future applications. When comparing the
results from the usability study with the result from technical evaluation it
was difficult to find components that offered both good usability and a good
technical construction. Some of the components performed well in the
usability study but not so well in the technical evaluation, and some the other
way around. It’s important to understand that both aspects are important in
order to have a successful product on the market. The technical area of
navigation devices is constantly changing meaning that the components are
continuously being developed and improved. It’s therefore important to stay
updated on what the market has to offer. (Less)
