“…The camera's sound system could also be used to convey audible proximity alarms. Combining video and obstacle warnings into one display may decrease the operator's workload and increase acceptance of the system (Bliss and Dunn, 2000;Flannagan and Sivak, 2005). Some of the tag-based systems already incorporate this feature, while the less expensive systems such as radar do not and would require more development work.…”

To this end, NIOSH started a research project in 2000 with three goals. The first goal included testing commercially available proximity warning systems on equipment used at mining operations. The second goal involved developing new technology or modifying existing systems to address the specific needs of this industry. The final research goal focused on making recommendations regarding testing and implementing

“…There has been similar concern about how the effective magnification of camera-based rear-vision systems may affect perception of distance. We have argued in the past that the effect of magnification on distance perception is unusually strong in the case of rearview mirrors because of the limited fields of view that they provide (Flannagan & Sivak, 2005). With larger fields of view, and the richer distance cues that those fields are likely to provide, the importance of magnification might be greatly diminished.…”

“…As they are actually mounted and aimed, the typical horizontal extents of the fields of view are 12.9 degrees for left exterior mirrors, 25.3 degrees for center mirrors, and 22.5 degrees for right exterior mirrors (Reed, Lehto, & Flannagan, 2000). It may be that the small sizes of these fields limit the usefulness of a variety of distance cues that could be used more effectively in a rear vision system with a larger, continuous field of view (Flannagan & Sivak, 2005).…”

The effects of image size on perceived distance have been of concern for convex rearview mirrors as well as camera-based rear vision systems. We suggest that the importance of image size is limited to cases-such as current rearview mirrors-in which the field of view is small. With larger, richer fields of view it is likely that other distance cues will dominate image size, thereby substantially diminishing the concern that distortions of size will result in distortions of distance perception. We report results from an experiment performed in a driving simulator, with static simulated rearward images, in which subjects were asked to make judgments about the distance to a rearward vehicle. The images showed a field of view substantially wider than provided by any of the individual rearview mirrors in current systems. The field of view was 38 degrees wide and was presented on displays that were either 16.7 or 8.5 degrees wide, thus minifying images by factors of 0.44 or 0.22. In contrast to previous studies of convex mirrors and camera-based rear vision systems, judgments about distance were not affected by image size, suggesting that distance cues other than size were available to subjects as they made their judgments. Further testing is needed to better understand the nature of the distance cues that drivers are able to use in camera-based rear vision systems, but these results suggest that, at least under some conditions, image size is not critical for reliable perception of distance.
