Developing an Application for Assessing the User's Functions while Operating the Touch Screen

In today's highly technology-oriented world, touch screen technology is rapidly becoming essential for participation in social, personal, and occupational activities. The aim of this study was to describe the processes of reaching consensus regarding the assessment of the user's skills required to operate various touch screen devices. A six-step procedure was used to collect and validate the required skills by a multidisciplinary team of 52 experts. Content validity was calculated to determine the agreement levels between the experts. A comparison was made between the discipline groups in order to test correlation between each group and their choice of specific clusters of tasks. The final number of domains and skills/measurements was 15 domains and 50 skills/measurements. The result of Cronbach's α test for the final assessment questionnaire (50 skills/measurements) was 0.94, which indicates a high degree of internal consistency. The results of Kruskal-Wallis test showed the lack of any significant difference between agreements of the clinicians and the technicians groups, but significant differences were found between the educators and the clinicians groups. Each of the skills appearing in the final questionnaire was illustrated in a flowchart in preparation for developing the assessment (tool) for using touch screen devices. (מתוך המאמר‎)
