| Heres how your very own butler, right in the dashboard of your car, might
respond to your needs, minimize distractions, keep you focused on your driving,
and help you avoid potential hazards. |
Telematics combines automakers, consumers, service industries. And computer
companies. Which is how IBM fits in. It knows a thing or two about computers,
data management, and connecting compute devices together. So people at its Thomas
J. Watson Research Center (Hawthorne, NY) are working to bring the technology
to a car or truck near you in the not-too-distant future.
Conversational telematics
IBMs Artificial Passenger is like having a butler in your carsomeone
who looks after you, takes care of your every need, is bent on providing service,
and has enough intelligence to anticipate your needs.
This voice-actuated telematics system helps you perform certain actions within
your car hands-free: turn on the radio, switch stations, adjust HVAC, make a
cell phone call, and more. It provides uniform access to devices and networked
services in and outside your car. It reports car conditions and external hazards
with minimal distraction. Plus, it helps you stay awake with some form of entertainment
when it detects youre getting drowsy.
In time, the Artificial Passenger technology will go beyond simple command-and-control.
Interactivity will be key. So will natural sounding dialog. For starters, it
wont be repetitive (Sorry your door is open, sorry your door is
open . . .). It will ask for corrections if it determines it misunderstood
you. The amount of information it provides will be based on its assessment
of the drivers cognitive load (i.e., the situation). It can learn
your habits, such as how you adjust your seat.
Parts of this technology are 12 to 18 months away from broad implementation.
Improving speech recognition
Youre driving at 70 mph, its raining hard, a truck is passing, the
car radio is blasting, and the A/C is on. Such noisy environments are a challenge
to speech recognition systems, including the Artificial Passenger.
IBMs Audio Visual Speech Recognition (AVSR) cuts through the noise. It
reads lips to augment speech recognition. Cameras focused on the drivers
mouth do the lip reading; IBMs Embedded ViaVoice does the speech recognition.
In places with moderate noise, where conventional speech recognition has a 1%
error rate, the error rate of AVSR is less than 1%. In places roughly ten times
noisier, speech recognition has about a 2% error rate; AVSRs is still
pretty good (1% error rate). When the ambient noise is just as loud as the driver
talking, speech recognition loses about 10% of the words; AVSR, 3%. Not great,
but certainly usable.
Analyzing data
The sensors and embedded controllers in todays cars collect a wealth of
data. The next step is to have them phone home, transmitting that
wealth back to those who can use those data. Making sense of that detailed data
is hardly a trivial matter, thoughespecially when divining transient problems
or analyzing data about the vehicles operation over time.
IBMs Automated Analysis Initiative is a data management system for identifying
failure trends and predicting specific vehicle failures before they happen.
The system comprises capturing, retrieving, storing, and analyzing vehicle data;
exploring data to identify features and trends; developing and testing reusable
analytics; and evaluating as well as deriving corrective measures. It involves
several reasoning techniques, including filters, transformations, fuzzy logic,
and clustering/mining.
Since 1999, this sort of technology has helped Peugeot diagnose and repair
90% of its cars within four hours, and 80% of its cars within a day (versus
days). An Internet-based diagnostics server reads the car data to determine
the root cause of a problem or lead the technician through a series of tests.
The server also takes a snapshot of the data and repair steps. Should
the problem reappear, the system has the fix readily available.
Sharing data
Collecting dynamic and event-driven data is one problem. Another is ensuring
data security, integrity, and regulatory compliance while sharing that data.
For instance, vehicle identifiers, locations, and diagnostics data from a fleet
of vehicles can be used by a variety of interested, and sometimes competitive,
parties. These data can be used to monitor the vehicles (something the fleet
agency will definitely want to do, and so too may an automaker eager to analyze
its vehicles performance), to trigger emergency roadside assistance (third-party
service provider), and to feed the local traffic helicopter report.
This IBM project is the basis of a Pay As You Drive program in
the United Kingdom. By monitoring car model data and policy-holder driving habits
(the ones that opt-in), an insurance company can establish fair premiums based
on car model and the drivers safety record. The technology is also behind
the black boxes readied for New York Citys yellow taxis and
limousines. These boxes help prevent fraud, especially when accidents occur,
by radioing vehicular information such as speed, location, and seat belt use.

2003 issue.)
Retrieving live data on-demand
Plumbingthe infrastructure stuff. In time, telematics will
be another web service, using sophisticated back-end data processing of live
and stored data from a variety of distributed, sometimes unconventional, external
data sources, such as other cars, sensors, phone directories, e-coupon servers,
even wireless PDAs. IBM calls this its Resource Manager, a software
server for retrieving and delivering live data on-demand. This server will have
to manage a broad range of data that frequently, constantly, and rapidly change.
The server must give service providers the ability to declare what data they
want, even without knowing exactly where those data reside. Moreover, the server
must scale to encompass the increasing numbers of telematics-enabled cars, the
huge volumes of data collected, and all the data out on the Internet.
A future application of this technology would provide you with a shortest-time
routing based on road conditions changing because of weather and traffic, remote
diagnostics of your car and cars on your route, destination requirements (your
flight has been delayed), and nearby incentives (e-coupons for restaurants
along your way).
