End users tested the system in doctor-nurse pairs. The doctor was wearing the interaction wristband and a Bluetooth headset for audio in and output. The nurse was given a PDA. Each evaluation session started with an introduction to the project. After a short explanation of the prototype, the doctors and nurses trained to operate with the system. The training session was split into two halves. During the first part, the doctor and nurse were introduced into the systems usage and asked to familiarize themselves with the interaction methods.
After a certain degree of proficiency with the system was reached, a sequence of activities similar to that of the actual tests was explained and performed. During the training, instructions were given to the participants. Subsequently, an evaluation sequence was performed three times.
Therefore, the doctors and nurses entered the room via the door. Next to the patientís bed, the doctor had to use the interaction wristband to scan the patientís identification wristband. The system brought up the patients files on the bedside display. The doctors had to open a document and scroll to its end containing instructions about the next steps, e.g. opening another document. The last document contained instructions to perform an examination of a certain patientís body part. In a last step, the doctor issued an examination request that was completed by the nurse.
Finally, the practical part of the experiment, the participants filled out a questionnaire concerning their experience using the system.
