Evaluate an immunization record model by remote user interaction through Internet

Assessment of health information system (HIS) during development can help to identify and resolve system weakness. Prototype helps to depict system behavior and some of the features of the eventual program to the end-user in early development stages. Think aloud and constructive interactions are two common usability engineering methods that suggested for system evaluation. In this paper, we proposed to use constructive interaction method to evaluate an immunization record model, and we used Skype to test the model over distance with the help of health professionals. Constructive interaction was effective in this study because Skype allowed face-to-face communication, and tasks were distributed among people in each session. Skype helped users in separate location work collaboratively on evaluation process.
