Expected comfort | Global comfort for “Reading&Writing” task | Global comfort for “Laptop use” task | |
---|---|---|---|
Library chair | 0.500 | −1.036 | −1.464 |
Redesigned chair | 1.889 | 2.036 | 2.179 |
Reading and writing | Laptop using | |
---|---|---|

4 Conclusions
-
redesign of the chair and realization of prototype;
-
comparison analysis between the original library chair and the redesigned one throughout experiments to collect subjective data (questionnaires) and objective data (video recording to detect postural movements);
-
statistical analysis and discussion of outcomes for improvement assessment.
