Chapter 4
Use of the stop button
When inexperienced Michelle (56yrs) noticed most of her answers were missing from the summary in question 6, she got confused. In question 6 she was asked to choose the three most important activities in which she was limited. The screen contained only one activity-photo while, in her mind, she had selected a lot of photo’s earlier. Except for the one photo that she had managed to select, she had tapped on the text beneath the photos, in which case the item was not activated (see problem 5 in table 4.2.4). The activity on the one photo that she had managed to select was of no priority to her. Therefore, she decided to use the stop button and ended the questionnaire.
Inexperienced Bill (72yrs) had a lot of trouble operating the questionnaire. He commented on the introduction clip:
“I do not think that what she is saying is difficult, but I just am not able to remember it. I have no experience with these kind of devices. So I forgot what she said right away.”
Bill managed to get to question 4 by activating the help function on each screen he entered. When he touched the navigation button to see all the activity-photo’s in question 4, the photo gallery moved in a different direction then he had presumed. This startled him somewhat and made him forget that he had to push the next button to go to the next screen (see problem 7 in table 4.2.4). He activated the help function again, but that was of no use anymore. After trying a few buttons without succeeding to go to the next screen he gave up and tapped on the stop button.
Inexperienced Helga (54yrs) operated the digital questionnaire fluently until she had to choose the three activities that were most important to her in question 5. She did not use the navigation function of the photo-gallery and as a result she did not see all her earlier selected activities (see problem 4 in table 4.2.4). She chose the three most important activities out of the five photos that were immediately visible. When she realized what happened she wanted to pause for a moment to find out how she could change her answer. She interpreted the stop button as a ‘time-out-function’ and was a bit shocked when she found out that she had stopped the questionnaire altogether.
A complete overview of frequency and severity of all problems encountered can be found in table 4.2.4.
