Recently emotions started to receive more attention from IT use researchers. However, similarly to psychology, much of the focus goes to investigation of negative emotion influence. Drawing on broaden-and-build theory and flow theory, this manuscript aims to explore how positive emotions can influence enhanced IT use. In order to test it, experiment study is proposed. Findings are expected to support influence of positive emotions on enhanced IT use via state of flow. This suggests that organizations seeking to improve individual IT use should aim to stimulate positive emotions in individual users.
