SMART CARNatural User Interface Technology CAR CUSTOMIZATION BY USER RECOGNITION
Smart Car • Definition: An automobile with an advanced system which can provide an enhanced driving experience and also provides active safety features
State of the Art • Crash Avoidance Systems • Energy Consumption • Lane Tracking • Night-vision Obstacle Detection • Smart Cruise Control • Driver-Car Vocal interaction
Car Technology in the works… • Self-driven cars. • AugmentedRealitydashboards – Windshields and touch-screenwindows(BMW & Toyota). • Adaptive Highbeam Assist (Lexus) – graduallyadjusting light distributionbasedondistance of approaching cars.
Future Car Technologies • Vehicle-to-vehiclecommunication (V2V) – usingwirelesssignals to sendinformationbetween cars. • Vehicle-to-infrastructurecommunication (V2I) – allowvehiclescommunicationwithtrafficsignals. • Provideinformation to vehicleabout safety issues • WiFi Internet Access in movingvehicles.
What are driver’s needs? • COMFORT • ASSISTANCE • SECURITY
What do we provide? • A user-friendly system, based on a NUIT: • Recognition of the driver who takes a seat • Loading of a user-based profile with a given customization • The needs of the specific user are fulfilled
NUIT appliedto Smart Car • Whichtechnologies are weimplementingtodevelop a Natural User Interface? • FACE RECOGNITION • SPEECH RECOGNITION
FaceRecognition • Cross-correlation? • Face-tracking to look forcertainpatterns to detectmoodor fatigue/tiredness? • …
Problems of Face Recognition • Creating a unique face signature for every person • Sun glasses • Painted eyebrows • Long hair • Beards • Viewing angle of face • Poor lighting • Big smiles • Privacy
SpeechRecognition • Cross correlation? • Dynamic Time Warping? • HiddenMarkovModels • …
Problems of Speech Recognition • Error rates increase as the vocabulary size grows • The 10 digits "zero" to "nine" can be recognized essentially perfectly, but vocabulary sizes of 200, 5000 or 100000 may have error rates of 3%, 7% or 45% respectively. • Spontaneous Speech like “uh” and “um” • Environmental noise (e.g. Noise in a car or a factory) • Acoustical distortions (e.g. echoes, room acoustics) • Homonyms Hidden Markov Models
