Page 154 - THE DUTCH TALKING TOUCH SCREEN QUESTIONNAIRE

Evoluation of the Dutch and Turkish version because they failed to select answer options and/or unintentionally skipped questions because of problems like tapping on the text underneath a photograph instead of on the photograph itself and by double-tapping on the next button (see Problems 1, 3, 4 and 5 in Table 4.3.4). None of the participants noticed they had failed to select answer options or skipped questions while they were completing the questionnaire. Stopped completing prematurely Inexperienced Ceyda (65y) read the first question ‘Do you have pain’ (see appendix 2, screenshot 2 ‘Pain’). She was very doubtful about what answer would be right because her pain had decreased since her first physical therapy visit. She gave back the Turkish TTSQ to the researcher without answering the question because she was not able to decide on her answer and skipping the question was not a possibility. Afterwards, during interview Step 3, she told the researcher that she did not know that the red square with ‘yes’ in it and the green square with ‘no’ in it were ‘buttons’ which she could have tapped to insert an answer. Inexperienced Meryem (74y) did not know what to do with the tablet. She read the first question and then spoke directly to researcher MW to give the answer. When the researcher asked her what she thought she should do next, she answered: “Well, I hope to benefit from the therapy. That’s what I am going for.” When the researcher then asked her if she had any idea what she should do with ‘the screen,’ she seemed to get somewhat nervous and almost whispered: “I don’t know, I do not know what to say”. Inexperienced Memhet (59y) managed to get to Question 4 without encountering any serious or critical usability problems. In this question, he was asked to select photographs of activities in which he was limited (see appendix 2, screenshot 7 ‘Activity ‘lying’). Memhet tapped on the text beneath the photographs most of the time instead of on the given photographs. He did not notice that this was not sufficient to select the answering option and therefore thought that he had selected far more photos than he actually had. In Question 5, he was asked to select the three activities that were most important to him 153 4.3
