Public Meeting
This page is devoted to discussions regarding specific in-vehicle technologies: cell phones, navigation systems, night vision systems, wireless Internet, and information and entertainment systems, among others. The purpose is to provide an avenue for drivers to share their experiences with, and impressions of these technologies so that benefits of these systems can be realized without causing unsafe driver distraction. Although specific in-vehicle devices are emphasized here, comment and discussion relevant to other non-technological or conventional sources of distraction are also welcome. Be sure to take or view results of our informal polls.

Please tell us about your experience with these technologies…

Refering to: Good Idea

Although the idea of HUDs in cars may seem like an appropriate application of a "proven" technology (as was mentioned, HUDs have been in military and commercial aircraft for quite some time), it has not been demonstrated that HUDs are appropriate, or even necessary, for use in cars. The idea is that drivers won't have to risk taking their eyes off the road to acquire information (as with standard instrument panel displays) because (1) the HUD image is closer to the forward line-of-sight, (2) it is possible to see through the image (so, you may still be able to see the road behind the HUD image), and (3) the virtual image distance (typically greater than 10 feet ahead) is more comfortable for most viewers (particularly older drivers with presbyopia). These are some of the reasons HUDs should benefit drivers. At least, that's the theory. What's the practice? Although it is too soon to tell for sure, actual drivers using automotive HUDs may experience numerous problems. For example, the eye has to be within a small 3-D space (called the eye box) in order to acquire the image. So, if you're head is outside the eye box, you will miss important information displayed on the HUD. More pertinent to this forum is the fact that HUDs may be distracting. This may be particularly true at night when workload is "low" (drivers may be bored and/or fatigued). Also, it is important to keep in mind that HUDs will not serve as the primary information source for driving a car(at least not in the foreseeable future). In contrast, HUDs are often the primary information source for aviators. So, anytime the driver glances at the HUD it could (I am playing devil's advocate here a bit) be categorized as a distraction, even though (in the case of Night Vision systems) it is providing longer previews to some objects. So, should HUDs and/or Night Vision be in cars or not? Any opinions? Experiences? We want to hear from you.
