| When product or service provides unexpectedness the user would be satisfied, and lately some mobile applications and web services provide those unexpectedness. However, unexpectedness itself can make negative effects such as decrease of the ease of use, still studies about mobile application are focused on satisfaction from the usability. Therefore, we would study experimentally user experience changes caused by unexpectedness using serendipity in mobile application UX, and observe how those changes to affect to user satisfaction. In other words, we observed the relationship between factors such as the unexpectedness caused by interactions of mobile application, the serendipity provided game, perceived newness, perceived ease of use, perceived usability, and satisfaction. As a result, the serendipity has positive effect to the perceived newness and negative effect to the perceived ease of use, and perceived newness and perceived ease of use affect to perceived usability positively, and all three factors are have positive effects to the use satisfaction. |
