Intentions to use location-based services : refining a predictive model and understanding contexts of use

摘要

This thesis is concerned with the processes involved in the perception, adoption and use of location-based services (LBS). Location-based services are able to pinpoint the geographical position of an individual and are most often deployed on mobile devices. The capability for LBS to be integrated into other systems such as social networking sites is also growing. The focus of current LBS research is on the development of security measures to protect privacy. The actual privacy concerns of real LBS users, however, have not been considered. The work in this thesis examines location-based services from a user perspective. A previously untested predictive model of LBS was assessed, and shown to be unsuited to account for intentions to use the technology in a workplace setting. A revised and improved model is proposed that suggests four factors account for intentions: perceived usefulness, trust of the LBS provider, disclosure to employer and trust of the employer. This research investigated the types of location information that might be disclosed when using LBS, who the recipients might be, and how people categorise location information into meaningful clusters. Results showed that people have explicit LBS preferences, with the receiver of information and context playing a large role in determining disclosure. Three qualitative case studies aimed to understand implications of LBS use with different populations. Participants raised concerns about trustworthiness of their employer and knowledge of LBS providers, providing support for the theoretical model. These case studies suggest LBS could also successfully be applied to alternate user groups. These findings have important implications for LBS providers and industry. People have a desire to know who the LBS provider is and what role they will play. Making these issues explicit should improve trust and develop the user-LBS provider relationship. When implementing LBS in the workplace, consultation with employees and providing clear information may enhance trust of the employer.
