ABSTRACT
Personal mobile devices are increasingly being used as platforms for interactive services. Ease of use
is important, but the services should also provide clear value to the user and they should be trustworthy
and easy to adopt. These user acceptance factors form the core of the Technology Acceptance Model
for Mobile Services introduced in this chapter. The model has been set up based on field trials of sev-
eral mobile services with altogether more than 200 test users. This chapter presents the technology
acceptance model and describes four case studies of applying the model in practice as a design and
evaluation framework.

implementations. Small mobile devices pose
significant usability challenges and the usability
of the services is still worth studying. However,
more attention should be paid to user acceptance
of the planned services. The reason for many
