Abstract
There are still a number of issues in designing effective user interfaces. The authors states that cognition plays a major role in the design of user interface along with other things such as information needs, work activities, and reasoning. The authors believe that there is still room for improving our understanding of human computer interaction.
Summary
In this paper, the authors discuss various different aspects of how cognitive science affect human-computer interaction. They talk about evaluating user interface by the use of "think aloud" protocols and video recording to evaluate a user's interaction on the computer screen. The authors also looked at why it is important to study individual and group interactions among clinicians and the differences between having the end user test a system's interface in a controlled environment compared to a real world environment. The paper also involves a discussion of the evolution of user interfaces. For instance, early user interfaces were strictly command-line interfaces such as UNIX and DOS. In the 80's, graphical user interfaces (GUI) were introduced, then in more recent years, there was interactive user interfaces and network user interfaces.
Comments
The authors does a good job explaining why cognition has such a big impact on user interface designs. Even though this paper is a bit older, everything that the authors touches on is still valid. A well designed user interface for an electronic health records (EHR) should support the end user's cognitive capabilities. If an EHR has too much information on one screen or if the design is too complex, this can cause information overload. On the other hand, if information on the EHR is randomly spread out between multiple screens, this can break the mental workflow of the end user. The cognitive limitations and capabilities of the end user also plays a factor in designing an effective UI. With the constant development of technology and user interfaces, it is crucial to have new studies that keeps up with these changes.
