Equipment Design Features (Impacts on Safety)

DISCUSSION ISSUES/TOPICS

Effective/Ineffective Designs & Countermeasures

• What technologies can be employed to develop less distracting devices (e.g., voice recognition, hands free operation)?
• To what extent does voice interaction (speech recognition, artificial speech) provide benefits over visual presentation? Under what conditions is voice communication distracting?
• Is there less driver distraction with the use of Head Up Displays (HUDs) than with traditional displays? Can everyone use HUDs effectively?
• How should information be structured, formatted, and searched? How much information is too much for drivers to handle?
• What designs and features (design soluations) have worked well in this or similar applications? What problems have been observed?
• What effective countermeasures can be used to combat distraction?

• What are the important unanswered questions regarding the design of in-vehicle technologies? Is research best directed at defining good design or developing tools to evaluate individual designs?

(adaptive driver assistance) research is conducted with the aim to adapt driver assistance in a manner to counteract possible influences of in-vehicle communication on driving. A prerequisite towards this aim is a thorough understanding of the effects of communication on driving. An experiment is presented in which three prototypical driver-car interactions were used: a visual and an auditory information processing task and a manual operation task. According to Multiple Resources Theory these different in-vehicle communications are to interfere with the driving task in a varying amount and pattern. The effects of these communication tasks were examined in a driving-simulation task in which one half of the participants had to maintain their driving speed without and with a preceding car on a straight road while the other half of the participants had to control their lateral position on a curvy road while driving at a recommended speed. Overall, thirty subjects took part in a mixed between-within subject design. First of all, we found distinct changes in the driving behavior caused by the communication tasks. Most strongly, the control of the lateral position of the car deteriorates. Second, the manual operation task causes the greatest interference with the driving task followed by the visual and the auditory information processing task. Third, the driving task has a negative effect on the performance in the in-vehicle communication tasks. These findings support the assumption that advanced driver support systems have to be adapted to different kinds of in-vehicle communication and gives indications of how to design this adaptation. A successful adaptation may also increase the acceptance of these adaptive driver assistance systems if they do not only improve driving behavior but also in-vehicle communication.   If purchasing an in-vehicle device, how much of an influence does the design and ease of use of devices have on your selection?      Can auditory systems (devices with the capability to interpret voice commands, or communicate using speech messages) address the safety concerns associated with operating in-vehicle technologies?      Do you believe hands-free technology is sufficient to address safety concerns related to cell phone use while driving?      Is it possible to design electronic maps that can be safely used while driving?      Is it possible to design wireless Internet devices (e.g., e-mail systems) that can be safely used while driving?      Integration of Driver in vehicle ITS   7/6/00 2:13:53 PM   In your opinion, what is the maximum number of recommended information displays a HUD should feature?    7/14/00 8:52:05 AM   Passenger Air Bag technology saves lives, BUT...   7/14/00 6:11:10 PM   Radio designs are needlessly dangerous   7/18/00 3:04:26 PM   Radio designs are needlessly dangerous, II   7/18/00 6:32:12 PM   Possible solution   7/18/00 6:44:54 PM   disable devices while car is in motion   7/19/00 11:19:00 AM   low cost "black-box" equipment for motor vehicles   7/19/00 11:50:17 AM   In your opinion, what is the maximum number of recommended information displays a HUD should feature?
