In the following, the Technology Acceptance
Model for Mobile Services (Kaasinen, 2005b) is
described. The model aims at taking into account
the aforementioned special characteristics of
mobile consumer services, and previous studies
on user acceptance described in this chapter. The
model can be utilized when designing new ser-
vices and assessing them to ensure that key user
acceptance factors are considered in the design.
activities involving over 200 users. The studies
were carried out as parts of technology develop-
ment projects in 1999-2002 by project usability
teams comprising altogether 13 researchers from
VTT and three researchers from other research
organizations. The main focus of the studies was
on mobile Internet services and location-based
services targeted at consumers (Kaasinen, 2005b).
Table 1 gives an overview of the user evaluation
activities that the Technology Acceptance Model
for Mobile Services is based on.
The original Technology Acceptance Model
was chosen as the starting point for the new
model because it provided a framework for con-
necting field study findings on ease of use and
usefulness. The user acceptance framework is
Technology Acceptance Model
for Mobile Services (TAMM)
The Technology Acceptance Model for Mobile
Services (TAMM) was constituted on the basis
of a series of field trials and other user evaluation
