Abstract:The aim of this bachelor assignment is to design a user interface for controlling functions specific to an ambulance. The functions will be linked into a central system, it includes the illumination points, beacon, audio signal and flashes. This is all driven by a system of Hortec B.V. The airsuspension of VB Airsuspension is also linked to the system so the user can control the height of the suspension from an interface. The various functions, the above two companies and the various interfaces in the current ambulances are introduced in Chapter 1. Each design choice will be carefully justified and based on the demands and wishes of the users who use an ambulance. They will also be based on the applicable laws for interfaces in vehicles. This is achieved by looking at what functions should be usable from the perspective of the ambulance driver. Next we looked at how these functions most efficiently could be managed. Then research was done about the demands and wishes of both the person who proceeds to purchase ambulances as well to the demands and wishes of the driver of an ambulance. Also in Chapter 2 is explained what the laws or guidelines are which apply in terms of design and ergonomics of a system interface in a vehicle, according to European standards (Automotive). Then the available interfaces that are currently on the market are introduced. This hardware is the basis on which the scenario-based interface will be shown. The scenarios that are conceived and designed are explained in Chapter 3. This chapter also shows that it is possible for the hardware to function in an ambulance. These results from the first three chapters are basis for a list of requirements for an interface. Next a number of concept designs for an interface design were made. The program requirements can be found in Chapter 4. The concept designs were tested with using the list of requirements and a concept design choice is made. This conceptual design is further developed into a demonstrator which shows how the interface works. The concept design, concept selection and analysis of the selected concepts are described in Chapter 5. The results are two graphical interfaces where the focus is on scenario-based control. All functions within this interface can also be manually override. The two graphical interfaces are developed in Microsoft PowerPoint into a working prototype. This prototype is tested on the basis of the list of requirements and on feedback from a few users. They are satisfied with the results but improvements can be made in symbol design and system design. Finally, the demonstrators was presented to the ambulance builder. They found the design innovative and interesting, they question whether the marked is ready for this. It can be concluded that the two concepts properly support the ambulance drivers and give a comparative advantage in the current management of the functions in an ambulance.
