Objective: The aim of this study is to review literatures on the usability of ubiquitous service, and examine whether two approaches-usability and service quality approaches-are sufficient for the evaluation of ubiquitous service. Background: The emergence of ubiquitous technology and subsequent changes in life are bringing about incoming issues in service industry. Just as mobile payment system enabled users to replace annoying cash exchange in return for new problems of privacy and security, so is happening with commercial prevailing of ubiquitous service. It is, therefore, important to put all possible issues into consideration in evaluating a service with new technology, which necessitates inter-disciplinary approaches. Method: Prior to examination, current service concepts of ubiquitous system are observed, and related literatures are reviewed to delineate the attributes of ubiquitous service. Then, collected attributes of ubiquitous service are categorized into 3 perspectives: technology-, service-, and user-oriented attributes. User-oriented attributes are examined if they can be evaluated by typical usability approaches. Similarly, both technology- and service-oriented attributes are examined if they can be evaluated by service-quality approaches. Results: For usability approach, ‘invisible’ and ‘unobtrusive’ attributes of ubiquitous service is hard to be captured because typical usability test is dependent upon what user perceives. Also, service quality approach lacks holistic point of view to evaluate the scope of service properly. Conclusion: An analysis of various evaluation methods presents that the evaluation of ubiquitous services should consider the purpose of evaluation, the focus of evaluation and various evaluation techniques for further development. Application: It is expected that the results of this study could provide new direction of evaluation method for ubiquitous service.
