Abstract

This study aims to determine the level of ergonomic risks among tablet users by three ergonomics experts. Thirty tablet users had their ergonomic risks examined using the Rapid Upper Limb Assessment (RULA) while studying for 30 minutes (taking notes and tilting their neck to read a projector screen). The results showed that almost all the tablet users had a total RULA grand score of 6 out of 7 on both sides. (“taking note” right: 73.30%, left: 90.00%, “tilting their neck to read a projector screen” right: 73.30%, left: 80.0%). These ergonomic risk levels indicated that usage of tablets in educational settings is becoming a problem and it should be investigated. In conclusion, the ergonomic risks among tablet users while studying (taking notes and looking up at a projector screen) were high. This may result in musculoskeletal issues in the affected area. More research should be conducted, and the relevant areas should be improved as soon as possible.
