Ergonomic evaluation and optimization of levels of temperature, viewing angle and viewing distance on text readability task / Zulquernain Mallick, Abid Haleem and Arshad Noor Siddiquee

The widespread usage of computers and its prolonged use has been shown to be a risk factor for musculoskeletal and visual discomfort. This paper presents a study in which the effect of operating parameters such as levels of temperature, viewing angle and viewing distance were analyzed. In addition,...
