Laptop displays performance: Compliance assessment with visual ergonomics requirements

The use of display devices such as smartphones, tablets, laptops is now massive and continuous in everyday life. It, therefore, becomes increasingly important to be aware the performance these devices, not only terms tasks performed but also interaction with humans therefore knows any possible effect on ergonomics vision. Following previous research activities conducted by authors assessment visual at video terminal workstations, aim this study evaluate human-system laptop displays. In details, a sample 57 displays analyzed accordance requirements EN ISO 9241-3xx series international standards related luminance, luminance ratio, contrast non-uniformity. An extensive measurement campaign was carried out using special pattern that allowed measure 13 different areas results obtained activity showed great variability between Almost all are able emit high levels almost meet requirement However, several did recommended values ratio. Furthermore, created simplified graph allow rapid evaluation This method could periodically used practice order residual level.
