Abstract
There are 2 billion social networking application users worldwide, of which 1.6 billion at least once a month usage. Since social application is the most people use on Internet, people could expect future expansion to new electronic devices such as wearables. And that will cause new challenges on user scenarios and interaction models. The purpose of the study is to know unmet needs and HCI issues for social networking applications on wearables. Through 30 questionnaire, taking eight representative users to generate Persona, especially in user pain points. In addition, using hands-on wearables test to recommend how interaction models could be. The result of the unmet needs are mainly in "Do not miss important messages ", "Do not see the message does not need to hurry", "Do not want to respond immediately" and so on. In the hands-on, sending messages by voice is the most accepted method and standard reply is not common acceptable. Message reminds by vibration is the most acceptable way, but only the retired group dislike it. A few users recommend to have “checking if new messages” function on wearables. In message display function, message is usually too long to completely display on the wearable screen. Most users said that the incomplete message is still useful, since people could judge if take the mobile phone for the complete message. For the retired group, small text is not acceptable, converting to a voice message output could be useful. Other features are recommended, such as an emergency call function, video chat, and social message transferring to calendar reminder. In this paper, the qualitative method is used to explore ideas of social application on wearables. For future study, quantitative research methods are highly recommended. In addition, understanding the reason behind the needs can be used to expand the design considerations of different product/services. Moreover, heavy users of social application still considered negative behavior. Researchers could consider different designs of interview to know more on this kind of users.
