In-car Entertainment System

  1. 1. Team Mammees Final Prototype 19 December 2011
  2. 2. OverviewTechnologyUsers + ContextsScenarios + PrototypePrototype Evolution
  3. 3. Overview Travel Guru, the immersive in-car assistant, helps you find your destination, in every sense.
  4. 4. OverviewTravel Guru enhances travel, helping you find awesome stuffand to have a good time-- all without ever taking your eyes offthe road. 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.
  5. 5. BackgroundResearch
  6. 6. TechnologyBackgroundHeads 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 speechrecognition, essentially the level of Siri. Audio systems are redundant.
  7. 7. TechnologyBackgroundTablet  Provides in-depth interaction between the passenger and the drivers HUD interface  Provides opportunity for research, education and trip planning
  8. 8. TechnologyResearchGM 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 roadBMW HUD  Displays speed and navigation directions  Responds to light, adjusting its brightness for daytime, nighttime or hazy conditions
  9. 9. TechnologyResearchVirtual Cable  Presents a way-finding line visible right through the windshieldTablets 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
  10. 10. User ProfileContext Analysis
  11. 11. Users + ContextsUser ProfilesDriver + Front Passenger (45 to 65 years old) Physical May suffer from declining visual acuity, spatial and temporal contrast sensitivity, and motion perception. Cognitive May suffer from declining working memory, including attentional limitations such as multiple object tracking. Technical Literacy May have low to average skill with current technologies; are familiar with tablets and gestures; comfortable with GPS or map services like Google Maps. Domain Literacy Are licensed drivers in the U.S., with familiarity with U.S. road systems and rules. Language Ability Are fluent in English and can read basic directions and signs.

  14. 14. Scenarios + PrototypeDynamic Shopping (Driver + Passenger)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.

  24. 24. Scenarios + PrototypeDynamic Shopping (Driver Only)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.

  35. 35. Scenarios + PrototypePoints of InterestTraveling 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).

  60. 60. Appendix A: Additional ResearchUser + Driving ResearchTransportation 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)
  61. 61. Appendix A: Additional ResearchUser / Driver Distraction ResearchDrivers attitudes toward imperfect distraction mitigationstrategies (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.
