There should be a lot of signals to perceive where the user is sitting. If the phone is resting in the center console, the accelerometers can tell whether it is being lifted up to the right or to the left of the car whenever it is being used. It could tell whether it is resting in the center console or the left or right side of the car depending on the shape of arc, distance travelled, centrifugal forces whenever the car follows the road around a left vs. a right turn.
If they care about accuracy to put in the engineering investment, it could be right a very high percentage of the time.
- michaelmrose 7y agoMy phone sometimes insists I'm driving on water. I don't believe you can tell the difference between drivers and passengers seats without in car sensors.
- rubyfan 7y agoThey can tell by which way you enter the car. This is problematic since women commonly put their purse in the passenger seat sometimes via the passenger door.
- michaelmrose 7y agoYou can easily be off by meters or even 10s of meters in terms of the position of the phone. You have no way to know the position of the car in relation. You would need car sensors and per car interior data and even then it would likely confuse a driver holding a phone in their right hand and a passenger holding it in their left. You talk about the phone keeping track of where the phone not only is but was historically in order to guess if you are driving and texting and I hear you want to design a broken system that is not even deterministically broken. It also fails to account for people passing a phone around to someone else in the car. I wouldn't be able to give my phone to a passenger because it would already have decided it is a a driver's phone. Your users will only be able to use your phone if they can reverse engineer what their phone thinks they are doing. Anyone who does not charge their phone will see car travel destroy their battery life. One can trivially avoid such a feature by disabling GPS but most people won't have to worry about it because they just won't pay hundreds of dollars more for a phone that randomly doesn't work even in the passenger seat because it's incorrectly second guessing you.
- testpostpls 7y agoYour phone can just use its camera(s) to figure out where it is inside a car.
- batsy71 7y agoBeing able to detect which lane of the road you are on is still challenging enough for self-drive technology. A cheap phone sensor most likely doesn't have such spatial resolution.
- watermanio 7y agoThere are probably simpler ways - for example, if an accident report states there was only one person in the car, it was probably the driver using his phone.
- asdff 7y agoSo what happens to my rates if I sit in the back left seat and the uber driver is an absolute maniac on the road.
