Background
Research
Heads Up Display (HUD) HUD used to limit the heads-down interactions in the vehicle.
Research shows decreased accidents.
Transparent display uses lasers to create a full dashboard interface.
Audio supplement: limited commands to the system via speech recognition, essentially the level of Siri. Audio systems are redundant.
Technology Background
Tablet Provides in-depth interaction between the passenger and the
driver's HUD interface
Provides opportunity for research, education and trip planning
Technology Background
GM Enhanced Vision Systems
Windshield is coated with transparent phosphors that emit light when excited by a compact laser, turning the entire windshield into a “monitor.”
Vehicle’s infrared cameras can identify the edge of the road
BMW HUD
Displays speed and navigation directions
Responds to light, adjusting its brightness for daytime, nighttime or hazy conditions
Technology Research
Virtual Cable
Presents a way-finding line visible right through the windshield
Tablets for in-car infotainment
Smart phones: global positioning system (GPS) and media players
Tablets: similar levels of integration as smart phones, while sporting a larger screen size more suitable for content and information consumption

Points of Interest
Dining + Place Capture
Driver needs to utilize system without passenger assistance: Most features in the main menu, for example "Dynamic
Shopping", can be utilized. ○ For safety, cog load is kept low. Information density is kept
low and features are reduced.
Driver can scroll through options when cog load is low from driving (stopped at a light, driving on highway). ○ Steering wheel buttons are conveniently located. ○ Driver can turn HUD off with one press on
steering wheel button.

Traveling couple realizes there are lighthouses in the area: Passenger does initial search. HUD provides information to both driver and
passenger. ○ HUD uses lower part of windshield to display
important information to driver. HUD uses upper right corner as destination summary for passenger.
Driver can scroll through options when cog load is low from driving (stopped at a light, driving on highway).

Additional Research
Transportation in an Aging Society (Conference Proceedings)
• Fear of losing their way may limit the mobility of older drivers;
directions they can see/hear can help (Caird, J., 2004)
• Vision Enhancement Systems (VES) in the forms of heads up display
also appear promising for increasing mobility (Caird, J., 2004)
• Recommended crash avoidance systems for older drivers include heads up displays that enable drivers to see information on the windshield, rather than requiring them to refocus (Pike, J., 2004)
Appendix A: Additional Research User + Driving Research
Drivers' attitudes toward imperfect distraction mitigation strategies (Donmez, B., Boyle, L.N., Lee, J.D., McGehee, D.V.)
• Drivers indicated that while they have been distracted while driving,
they did not want to give up their in-vehicle devices unless required to by law
• When designing (safe) systems for middle-aged drivers, preserving
driver control of the in-vehicle system interactions may be necessary if the strategy is to be accepted.
• Mitigation strategies presented in an auditory format can be very annoying and are less likely to be accepted than visual-based strategies. Therefore, when safe, warnings should be conveyed visually.
