The use of the INCLUSIVE HMI leads to a 4.2 % reduction in the average time required. For the second use case, the use of the INCLUSIVE HMI leads to a much larger decrease in execution time of 69.7 % when compared to the current HMI system. Moreover, a usability questionnaire has been filled in by testers, allowing to conclude that the INCLUSIVE HMI was perceived as an improvement with regards to the current HMI for all dimensions, for instance frequently usage, complexity, ease of use, functions, consistency, and learning effort.
