Optimization suggestions for instrument‐cluster information using displays

— Suggestions are proposed to improve the way information is presented with heads-down displays (HDDs) to optimize the information and potentially reduce the duration and frequency of scans necessary by the driver to read the information. Using color as a secondary channel of information on vehicle meters could reduce scan frequency by increasing awareness in driver' s peripheral vision. Only showing relevant portion of scales can reduce the overall necessary area for display information and possibly reduce the number of fixations necessary to read the information from that area. Larger displays can be optimized with same considerations as other displays, butthe size creates an easier opportunity to be filled with information in a way that ends up distracting the driver. Elaborate or complex graphics that emphasize the full abilities of larger displays are probably best limited to non-driving conditions. Color displays also have the potential benefit of reconfigurability, which could have a significant impact on how information is presented. Reconfiguration concepts suggested include only showing information of interest, font-size adjustment, and using GPS information to augment speed information based on traffic, time of day, and weather conditions.
