| Abstract: | Canadian mine countermeasures (MCM) divers currently use a combination of different displays to provide them with information about their safety, equipment, and status. MCM divers require a single, integrated display to simplify information gathering, and to provide information from the dive supervisor. Ergonomic design guidelines were reviewed and modified for information display in the underwater environment. A two-phase experiment was conducted to determine the optimal font size and the optimal colour, contrast, and background combination(s) for underwater displays. Eighteen subjects viewed a series of displays in four environments that simulated a combination of light and dark, clear and turbid conditions. Each subject viewed over 210 display screens to compare different font sizes and colour and contrast combinations. Each screen was scored for accuracy and readability. Results showed that when designing an underwater display, character height should be approximately 6 mm (26 point font size) when using Arial font. The display should have a black (or dark) background with light foreground letters. Light orange or light green were found to be the optimum colours for use in the display. A set of ergonomic guidelines for the design of underwater displays were developed based on the results of this study. |
