A usability study of short message service on middle-aged users

摘要

Short Message Service (SMS) is a popular method of non-verbal communication. So far, the majority of research has been conducted upon teenagers and young adults. In our work, we investigate the use of SMS services by middleaged users. A usability study of SMS is conducted, evaluating how effectively middle-aged users engage in SMS activities. Ease of use and difficulties experienced by middle-aged users are assessed after completing predetermined scenarios and SMS tasks on two different mobile phone handsets. Such usability issues experienced by middle-aged users of SMS include the level complexity of the navigational keys and the need for efficiency.
