Analysing emotional impacts on acceptance of the HMI inside cars
This paper describes a differential acceptability and usability approach that was applied within two projects on advanced driver assistance systems. Computer simulations (virtual prototypes) of the human machine interface (HMI) and simple representation of a driving task were applied to conceptualise the HMI and to analyse emotional aspects on acceptance of the HMI inside cars. The approach is simple and doesn't require complex statistics. Also direct measurements by use of emotional scales are not necessary. The existence of emotional barriers to acceptability is revealed by the differential method. The emotional barriers themselves are identified by means of interviews.
