Investigating the Usability of a User Interface for Display of an Electro Vehicle in a Driving Simulation

One of the main aspects of each product is the user satisfaction of its usability. User satisfaction is led as the physical and mental efforts are minimized. In this paper, a driver interface is designed that can handle both auditory and visual alarms. This interface is used for warning drivers about the remained battery in the electrical engine. A driving simulator is used for evaluating the usability of driving while using this interface. The key index of the usability is a driver’s stress, when uses this interface under different situations. For data gathering, this interface is used in 12 experiments which each one consists of four steps with two active variables. These variables are alarm types and traffic congestion that change during simulation. The participants’ satisfaction is evaluated and the results show that there is a relationship between the usability and active variables.
