Analysis of Discomfort Factors in Smartphone Use

Abstract

We are facing security threats over the Internet that users are not aware of, such as malware infection as well as unauthorized access. We look into user interfaces which cause discomfort so that users can be more aware of security risks. Despite of our efforts on security protections, risk to encounter dangers is increasing by use of smartphones. This paper reports our research progress on discomfort factors with use of smartphones; we conducted a questionnaire survey and found factors that are supposed to cause discomfort when using smartphones obtained from the results of exploratory factor analysis. Through exploratory factor analysis, we came up with five factors that contribute to the discomfort feeling. In addition, we describe the verification results of the difference for each factor according to smartphone OSs (iOS/Android) and the smartphone usage period.
