The differences about roads, traffic control functions and driver behaviours in general have a significant impact on the design of ADFs. These differences need to be handled appropriately. An ADF should not be designed for only a specific country or region without considering these aspect. Secondly, there is a general trend towards an aging population. Due to degrading physical abilities, activities become more cumbersome. During the definition of ADFs, physical impairments of elderly drivers need to be considered.
Thirdly, there is a significant variability in users’ physical dimensions and anthropometry. Size and strength differences between genders can play a role. The ADF shall be designed to be operated by a variety of different users.
Due to this high variability of users, customer studies evaluating the ADF need to consider various factors, such as age, gender and socio-cultural background, as well as previous experience with ADFs or computers in general.
Main Question:
Is the diversity of different user groups taken into account?
Sub-Questions:
