All participants were satisfied with the ease of use of the questionnaire. The use of plain language, the way ICT was used and the way the user interface was designed was greatly appreciated by the participants: Inexperienced Dora (77yrs):
“Everything was well described. I am not always able to understand
everything, but this went well. I understood what was asked of me.”
Little experienced Roger (70yrs):
“I have trouble operating my mobile phone and I own a notebook but don’t you ask me how that thing works! I am capable of a lot but I am not technical in that way. [...] This was the first time for me to use a tablet computer. I only had to follow the instructions. I did not have to start it up or open something, it just started working and it shut down by itself. I thought it was easy to work with. Better than when you have to write things down.”
Average/high experienced Ellen (32yrs):
