Travel Guru, the immersive in-car assistant, helps you find your destination, in every sense.

Overview

Travel Guru enhances travel, helping you find awesome stuff and to have a good time-- all without ever taking your eyes off the road.

Overview

Explore the area Travel Guru provides rich points-of-interest search and display. Find everything from towering landmarks to niche, hole-in-the wall grub.

Be confident You’ll always know where to go and what lies ahead. GPS navigation and traffic alerts, as you need them.

Feel secure Even in the worst driving conditions, Trip Guru can help. Driving assistance highlights road edges and alerts you to potential collisions.

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

Dynamic Shopping (Driver + Passenger)

Dynamic Shopping (Driver Only)

Points of Interest

Dining + Place Capture

Driver and Passenger want to go shopping: Passenger uses tablet to find shopping hotspots.

Passenger sends new route location to HUD.

HUD augments reality to highlight points of interest.

Points of Interest


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.

Points of Interest


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).

Points of Interest


Passenger wants to research restaurants for possible dining later in the trip: Determine type of food, other parameters. Drill down to see more information.

Passenger wants to save a restaurant for later in Manhattan: Point tablet to the restaurant and "save“ location.

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.
