User evaluations to guide the design of an extended personal service environment for mobile services

This paper describes ongoing research on designing and developing personalised mobile services. An iterative research approach on technology push and user pull is applied. The technology push strand uses a top down approach of designing a Personal Service Environment (PSE) for mobile services. The PSE is defined as an environment that assists a user in finding, adapting and using services that fulfil his needs, given his personal profile, his mobility and his context. The user-pull strand conducted user evaluations to gain insights into tailoring behaviour of end-users. In order to derive user-tailoring data for PSE design, a questionnaire on personalisation of cellular phones was conducted. When combining these two approaches, both useful and usable personalised mobile services can be developed.
