Jordan (1998) believes that though usability has been emphasized in a design process, it does not seem to include positive feelings, such as, pride, excitement, or surprise. Therefore, he conducted a series of research studies pertinent to the product pleasure, and summarized eight positive and seven negative emotions while a user interacted with products. Similarly, in the research area of human-computer interaction (HCI), users’ interaction experience should always be focused in order to facilitate the design of pleasurable user interface.
This research adopts Jordan’s (1998) research concepts to investigate the pleasure of Website user interface. The experiment was divided into three stages. In the first stage, the author used in-depth interview to help generate participants’ opinions regarding Website interface pleasure. After that, the technique of protocol analysis was used to help summarize possible emotion terms that constructed a pleasurable Website. In the second stage of the experiment, a questionnaire was used to obtain participants opinions pertaining to the interface pleasure of sampled Websites. That is, by using the emotion terms generated from the first stage of experiment, a questionnaire with 7-interval Likert scale was used to help participants evaluate the degree of interface pleasure of sampled Websites. Several one-way analysis of variance (ANOVA) and post hoc comparisons (i.e., Duncan) were also conducted to help obtain detailed results. After that, the sampled Websites were divided into groups by the technique of Cluster analysis. The third stage of experiment is about the proof of pleasurable Website interface design guidelines. That is, by using the pleasurable Website interface design factors generated from the previous stages, a pleasurable Website was created as the experimental group. In addition, a Website with displeasurable design factors generated from the previous stages was also created as the control group for comparison purpose. Participants were invited to visit these two Websites and were required to express their pleasure feels regarding these two Websites.
The results generated from the first stage of experiment reveal that pleasurable Website user interfaces possess 9 positive emotion terms, i.e., pleasure, satisfy, feeling at ease, comfort, leisure, excite, excitement, enjoy, unconscious, and curious. Furthermore, they also provided 10 negative emotion terms, e.g., conflict, be in a maze, bored, be annoyed, uncomfortable, uncomfortable, unbearable, tired, disappointed, disfavor, and troublesome. The results generated from the second stage of experiment show that when a Website is created with one or several of the followings 7 interface design factors, it can be more pleasurable to interact with. These design factors are: (1) with the style of rational layout; (2) With TB type of navigation design; (3) photos that is played to enhance atmosphere; (4) the primary contents are displayed by animation; (5) with clear text area; (6) The sub-site is created by the TB type of navigation design; and (7) the primary content of sub-site is also displayed by animation. The results generated from the third stage of experiment actually prove that the incorporation of pleasurable Website interface design factors generated from the second stage of experiment can help create pleasurable Websites. In addition, the research results also reveal that the majority of participants would like to spend a little more time to interact with a Website designed with pleasure considerations, and their visiting frequency is also higher. On the contrary, participants tend to choose to leave a Website right away if they think they are interacting with a displeasurable Website.
