CHAPTER 5. ADAPTING MUTI TO THE USERS 102

Researcher: Besides the voicemail, the comments and the images, is there other information you would like to include in the message that goes to the doctor'?

Nurse: I should think that is enough.

Researcher: Is there any extra stuff you would want to send to her [refers to the Nurse]?

Doctor: What I said that previous time, it's enough to make a diagnosis. It's never going to be perfect but to see a patient in front of me {but] this information I can work with.

From the interviews we also discovered that both participants preferred using the headset as opposed to the CSIR VoIP phones as they allow one to type, talk and listen at the same time. Also, as already indicated in the second project cycle, they did not see an immediate value in adding video conferencing but concurred that this was because they had not experienced high quality video conferencing. In addition, we discovered in this project cycle that the power problems are better in winter when there are no strong winds or rain. This was supported by the fact that neither the nurse nor the doctor had the need to use the spare batteries for the laptops. Lastly, the interview revealed that the doctor would be leaving Sulenkama in October to return to Cuba. To our knowledge, the Department of Health (DoH) did not have a replacement doctor to take over from him and it was not certain when another doctor would be appointed to the Nessie Knight Hospital. Next, we describe the results we gathered from our observations of participants during the demonstration, training and testing sessions.

Observations

The following ideas for revising MuT! arose from observations of the doctor and nurse using MuT!

during the demonstration, training and testing sessions. We felt that the log in screen should be removed as it is not necessary to support multiple user profiles at this stage. Moreover, we found that feedback on when there are new messages in the Inbox needed to be improved. An idea for future work which we identified would be to add Short Message Service (SMS) (defined previously in Section 2.3) notification to recipients of messages to make them aware that new MuTI messages have arrived for them. We also decided that when a call is not answered, voicemail should be provided.

In general, as noted in the second project cycle as well, we found that the interface needs to be improved by removing the buttons and replacing them with a toolbar and adding icons as well as tooltips. Lastly and most importantly, we realised that received records should display both the time that the record was sent at as well as the time the record was received at. This would
