Siri's Creator Challenges Texting-While-Driving Study

waderoush writes "A rash of media reports last week, reporting on a study released by the Texas A&M Transportation Institute, implied that using voice-to-text apps like Siri or Vlingo while driving is no safer than manual texting. But Adam Cheyer, the co-inventor of Siri, says journalists took the wrong message from the study, which didn't test Siri or Vlingo in the recommended hands-free, eyes-free mode. In the study, researchers asked subjects to drive a closed course while they held an iPhone or Android phone in one hand, spoke messages into Siri or Vlingo, proofread the messages visually, and pressed buttons to send the messages. Under these conditions, driver response times were delayed by nearly a factor of two, the researchers found. 'Of course your driving performance is going to be degraded if you're reading screens and pushing buttons,' says Cheyer, who joined Apple in 2010 as part of the Siri acquisition and left the company two years later. To study whether voice-to-text apps are really safer than manual texting, he says, the Texas researchers should have tested Siri and Vlingo in car mode, where a Bluetooth headset or speakers are used to minimize visual and manual interaction. 'The study seems to have misunderstood how Siri was designed to be used,' Cheyer says. 'I don't think that there is any evidence that shows that if Siri and other systems are used properly in eyes-free mode, they are 'just as risky as texting.''"

one more distraction while driving

[bloodhawk]

I thought it has been long established through research that even a hands free cradle talking on the phone is a dangerous distraction while driving, Can't see how this can be less of a distraction than that even if it is better than manual texting. People have enough accidents without additional distractions.

Yes and talking to someone in the car is distracting too.

Actually, its not that distracting.

Other people in the car are aware of traffic conditions, they actually stop talking, they even point out dangerous situations (even fi from the back seat). Talking to a person in the passenger seat may actually be beneficial to driver safety.

Having a conversation on the phone, that requires concentration, can certainly be distracting, but even the simplest text message is far more distracting. All of the tests of this kind of stuff were done asking people to solve simple math problems or word games on the phone while driving over a challenging course in an unfamiliar vehicle.

Yaking on the bluetooth about nothing in particular while stuck in stop and go traffic simply isn't that dangerous as long as its hands free. The studies suggesting talking on the phone (hands free) is dangerous simply isn't born out by accident statistics. Texting while driving is born out by accident statistics.

"Designed to be used" vs. "actually used"

If the study tested Siri the way Siri is normally used, then how Siri was designed to be used is irrelevant.

Driving Performance

Of course your driving performance is going to be degraded if you're reading screens and pushing buttons,'

See, shit like this is why the Prophet Hicks was so adamant in his belief that advertising people should do the world a favor and kill themselves.

FYI, asshole, it's an issue because humans cannot multitask, and every second you pay attention to that goddamn toy is one more second you're not paying attention to the road.

Perhaps Mr. My-Sales-Figures-Are-More-Important-Than-Your-Safety should read the stacks upon stacks of other studies that prove any distraction from driving is dangerous. Even talking to the guy in the passenger seat.

too bad studies have proven otherwise

Merely having a conversation with someone impacts your driving; passengers tend to be aware of circumstances like intersections, onramps, cyclists, etc - but people on the other end of your call can't be. It's why Ray Lahood and NHTSA wanted cell phone calls by drivers to end, period. Then there's the issue of control of the car; regardless of whether or not you're "eyes free", if you're holding something in you hand, you're not able to control your vehicle as well as you can with two hands on the wheel. I attended a driving handling clinic (which was insanely fun) where they had you do a slalom course normally, and then do it holding a water bottle to the side of your head; the results speak for themselves.

I'll agree that most of a trip you feel like you're on autopilot the problem arises when something unexpected happens. If you have your eyes off the road when that unexpected happens you're a lot worse off than had you been paying attention. So yeah if you get to your destination safely then you can look back and say man that didn't take any conscious effort at all but that's not why you need to pay attention. You need to be on your toes for when something novel or out of the ordinary happens.
