ProScan Scenarios Skin Controls Diagrams Project

The development of an interface always starts with an analysis of the scenarios of use. When we worked on the scenarios of using the ProScan program, we took into account the maximum amount of details:

Scenario participants

Doctor, patient, paramedic or engineer

Goals of scenario participants

For example: getting an X-ray of the patient’s lungs, preparing a daily report on the photofluorographic room’s operations etc.

Situations where a particular scenario is used

Is the patient examined at the hospital or or in the field (with a movable photofluorographic room)?

Additional events and actions of the scenario

For example: while receiving the patient, the doctor may ask him or her questions etc.

What kind of information may scenario participants need to accomplish their goals?

For example: Did the patient’s home address change? Is there any visible improvement in the state of the patient’s lungs in comparison with the previous X-ray? etc.

The work on the program interface development was so organized as to allow the users’ work scenarios to determine the program functions, not vice versa.

For example, the previous version of the patient search form had a superfluous functionality and therefore used to take up most of the main window. The new version retained only the most frequently used search parameters, while the rest were relocated to a separate window not to distract the paramedic’s attention from the current task.

Top: before, bottom: after. The redesign of the search form allowed for clearing the space for additional columns in the list of patients and creating an overall feeling that the program is controllable

Based on the analysis of the scenarios, we decided not to use the traditional multi-window model for displaying and processing the X-ray pictures (one window—one X-ray). Instead, we used the “doctor’s workplace” metaphor.

In real life the doctor has a special stand to place one or a number of X-rays for comparison. In the new version of ProScan the doctor is offered three variants of organizing his workplace: one, two or four X-rays on the screen.

The doctor can place an X-ray picture from the available list in one of the frames. The X-rays of two different patients with the same pathology can thus be compared, or the patient’s recovery progress can be assessed by looking at his two X-rays.
