6.4 Prototype 2.3

Once we had seen the prototype as a Photoshop document, we started to further

develop and implement the interaction in Visual Basic. The purpose of this prototype

was to be able to provide the means of actual interaction, so that a scenario could be

conducted, where the user could solve a problem in the traditional way of working.

Based upon our experience from British Airways as well as information about the

content of an alarm, decisions were taken upon what information should be visual in the

different interaction steps.

The design changed in some details:

§ A stand by button is added since there seemed to be a need for a stand by list

with quick access

§ There is no longer a red frame around the object that is being handled since the

color red is associated with danger and alarms and all of the objects are alarms.

The colors of the alarms; white, black, blue and yellow was decided upon since

they does not change in appearance when having a defected color vision

.

§ The background colors have been changed, to make an even more distinct

separation to the three different areas of the view.

A scenario was created, with two different possibilities to solve it, using the traditional

way or the Disruption Manager. Finally there was a prototype with possible interaction in

six steps, containing static and pre-determined information.

Tests have been performed by applying colour palettes of different dichromatic types of colour

deficiencies (Rigden, 1999). https://traloihay.net
