“Technologies
used in the car that rely on Voice communications may have unintended
consequences that adversely affect road safety. The level of distraction and
the impact on safety can vary tremendously based on the task or the System the
driver is using”
President and Chief
Executive Officer of the AAA Foundation for Traffic Safety Peter Kissinger,
commenting on the study done by University of Utah that discovered that Hands-Free
Voice Assistant Systems cause distractions while driving
I
guess Apple’s Siri Voice Assistant may actually be a distraction while driving!
So
says a recent study conducted by the University of Utah at the request of the
AAA (American Automobile Association) Foundation for Traffic Safety which discerned
that some Hands-Free Voice Assistant Systems can cause distractions that
compromise Safety while driving as noted in the article “Siri
can be distraction to drivers: US study”, published Tuesday, October 07,
2014 4:47 PM, The Jamaica Observer
and “Sorry
Folks, Siri Is Still Distracting You While You're Driving”, published OCT.
7, 2014, 8:49 PM by SAM COLT, Business
Insider.
The
researchers from the University of Utah conducted their tests on a sample of forty
five (45) drivers using built-in Hands-Free Voice Assistant e.g. the Ford
MyFord Touch Voice-control System as well as smartphone based Apple’s Siri Voice
Assistant as stated in “'Siri,
stop distracting me': controlling smartphones while driving is dangerous, study
finds”, published Wednesday 8 October 2014 15.15 BST by Samuel Gibbs, The UK Guardian.
I
personally think this is unfair, but it's good to note that with all the Hands-Free
Voice Assistant Systems, a microphone was connected to the System and placed on
the lapel of the drivers near to their mouth so that they could talk at normal
volumes.
The
45 test drivers were then asked to make a nine (9) minute loop through a
residential neighborhood while doing the following tasks:
1.
Dial a 10-digit number
2.
Call a contact
3.
Change the radio station
4.
Play a CD using the Hands-Free Voice-control
Systems
The
researchers made sure to connected sensors to the drivers to measure the
following metrics:
1.
The driver’s mental capacity, possibly
using an EEG (Electro-encephalograph)
2.
Reaction time possibly via cameras
3.
Heart Rate using an ECG (Electrocardiograph)
University of Utah test
Voice Assistant - Siri Voice Assistant a Bad Apple for most Distracting
They
discovered that the various Hands-Free Voice Assistant Systems were actually as
distracting as normal cognitive problem solving, to quote the finding of the
researchers from the University of Utah: “This indicates that common Voice
tasks are generally more demanding than natural conversations, listening to the
radio, or listening to a book on tape”.
Apparently
Apple’s Siri Voice Assistant was the most distracting when rated on a scale of
1 to 5 with 5 being the most distracting:
4.0
for Apple’s Siri Voice Assistant
3.7
for the Chevrolet MyLink
3.1
for the Mercedes Ccommand
3.0
for the Ford Synch
2.7
for the Chrysler Uconnect
2.2
for the Hyundai Blue Link
1.7
for the Toyota's Entune
To
quote the researchers from the University of Utah findings as it relates
specifically to the Apple iPhone: “The participant neither looked at nor made
physical contact with the iPhone during these interactions. Even so, the
workload ratings exceeded category 4 on our workload scale – the highest
ratings that we have observed for any task”.
Apple’s
Siri Voice Assistant is used in Apple CarPlay as described in my blog article
entitled “Apple
to launch CarPlay at Geneva Auto Show in Geneva, Switzerland - Siri Voice
Assistant and Primesense bring Hands-Free Remote Control Revolution to The
Grand Budapest Hotel”.
If
these results are indeed true, then it suggests that the Siri Voice Assistant
used in Apple CarPlay needs more sensitive microphones as according to the
researchers, the accuracy of Voice detection contributed to the increased level
of distraction. Imagine having to repeat your request to the Siri Voice
Assistant because if got your request wrong and the building frustration while
driving.
In
your mind’s eye, you can see how this would affect your concentration while
driving.
Hands-Free Voice
Assistant Systems - Jamaica's Road Traffic Act needs amending to reflect this
reality
Interestingly,
the researchers at University of Utah also tried out the various Hands-Free Voice
Assistant Systems on updating Facebook or Twitter feeds while driving.
Apparently the Siri Voice Assistant was very distracting during these tasks,
albeit it does beg to wonder why you'd want to do such a thing while driving,
being as texting while driving is supposed to be illegal in most countries.
In
Jamaica, we're just in the process of making changes to the Road Traffic Act to
make Texting while driving illegal as noted in my blog article
entitled “Road
Traffic Act to be Amended to Ban Vehicular Cellphones and Tablet usage – HD
CCTV Enforcement necessary as Legislation needs Teeth”. Clearly, though,
some attention needs to be paid to Hands-Free Voice Assistant Systems,
especially Natural Language Voice Assistant Systems such as Siri, as they
apparently require a lot of mental activity, enough to cause you to crash.
This
is one more thing for the Island Traffic Authority, the ultimate authority
within the Road Traffic Act, to ban on Jamaican roads along with banning
cellphone usage, mandating Rear-View Cameras to reduce road fatalities due to
motorists reversing as proposed in my blog article
entitled “Island
Traffic Authority to be part of the Road Traffic Act - How HD CCTV Cameras and
Rear-View Cameras reduce Vehicles fatalities”
Overall
the researchers from the University of Utah concluded the following: “Poorly
executed Voice Systems may … [impose] high levels of mental demand on drivers
with the potential to also incur long glances away from the roadway in order to
check System status and understanding”.
Guess
the ultimate solution is to let the vehicle do the driving for you, as in the
case of Google's Fully Autonomous All-Electric Vehicles as explained in my blog article
entitled “Google
100 strong Fully Autonomous All-Electric Vehicles launched – 25 mph Limit on AI
Chauffeur in 2015 with Black Boxes makes Crashes like aeroplanes”.
The
study conducted by the University of Utah at the request of the AAA Foundation
needs to be replicated to see if it’s truthful. If so, then it suggests that
Apple and other Hands-Free Voice Assistant Systems will have to go back to the
drawing board to tweak Apple’s Siri Voice Assistant, which is used in Apple
CarPlay to not be such a distracting Bad Apple.
