Design outcomes

Primary

Measure	Time frame
Activity,QOL Definition: We adapt the form of the interval scale to the questionnaire vote, and take a score (5 points to 1 point) to every question. We set the value in the analysis item. The questions from No.1 to No.4 are about convenience. The questions from question No.5 to No.8 are about reassurance and safety. The questions from question No.9 to No.11 are about ecology and design. The questions from question No.12 to No.18 are about activity and QOL. The questions from question No.19 to No.20 are about sociality.	—
