"Smart" Billboards Debut in Sacramento
k0osh.CEOofCLIT writes "Remember the billboards in "Minority Report" that scanned your eyes and changed the advertisement based on your shopping preferences? The Sacramento Bee reports: "Soon, this sign along the Capital City Freeway will be able to change its message based on what radio stations motorists have tuned in.""Yeah, Chris can't spell. He and Rob should form a club. *grin*
I haven't seen it yet, you insensitive clod!
"All art is quite useless." -- Oscar Wilde
What I listen to in my car is nobody else's business. Anyone know how I can go about installing shielding around my radio?
Soon, the billboards will be giving us advice ala LA Story. "I think you would be happy if you bought a Gap Denim Jacket!"
Considering the type of "music" I listen to, people will be treated with some good porn when I drive by. Too bad for all the traffic accidents that will follow, though...
i think wrapping your entire car with tinfoil and chickenwire may do the trick. then again, that might possibly amplify your signal :-/
seriously, what's it show when you're not listening to a radio? or, even more interesting, what happens when i'm tuned into those sex-talk shows that come on after midnight. that has the potential to cause quite a few accidents!
Wait a second. This could be a good thing. This is companies actually using advanced, high-tech devices to affect the consumer and give a more relevent expeirence. I mean, integration of higher and higher technology into daily life is one of the goals right, as it'll increase the demand for cheaper and better versions of technology. Discounting the 1984-Orwelliean aspect of this, this could actually be a positive phenomenon, ushering in new advances in advertising that could carry over to security or everyday automation of various tasks.
Since when has this country used intellectual elite as a pejorative term?
So how exactly do these billboards figure out what radio stations people are listening to? Do radios emit EM signals that can be used to determine what they're tuned to (it's been a long time since I took a physics class, somebody help me out here)?
Yep - as do television sets.
It's called heterodyning, and is used to decode FM (frequency modulated) signals. Basically, you mix the signal coming in with the frequency you want to listen to, and the signal at that frequency gets amplified (due to the interference), and the outcome of that is rectified, amplified, and is ultimately what you listen to.
So the billboard picks up the frequency you're mixing the incoming signal with (because you need a frequency generator to create that frequency, and they will emit it -- there's not much you can do to stop it short of burying it in a completely metal box -- which kind of stops the incoming radio signal).

Hrm. The article describes what the billboards do, but they completely avoid the question of how these mystical "sensors" work. I thought I understood how a radio reciever works, but I don't understand how you could remotely determine the location of a radio *reciever*, much less *what* frequency said reciever is (um) recieving.
I'm thinking of cases in totalitarian governments during the last 100 years where people huddled around banned radios trying to get the BBC, or of the case of the BBC roaming around trying to find people who have working televisions but don't pay their television tax. Could sensors like this be used by govt.s to determine from outside a house whether there was a functioning radio/television reciever? Could similar tech be used to locate illegal cell/police scanners or radar detectors (in areas where such things are illegal)?
Would it be possible for me to build such a scanner and then legally walk around seeing what passing cars are listening to and what people are watching on tv, just out of curiousity?
Is there a physics major in the house?
Irritable, left-wing and possibly humorous bumper stickers and t-shirts
I only listen to NPR, what are they going to sell me? A platter of dead tree? Hah!
Bored with karma, be a fan/freak
"here's no passive way to do this at all"
They have mirrors with strings strategically placed around the vicinity of the billboard/freeway.
When a car drives past a camera detects the cars velocity and starts adjusting the mirrors untill one of them can peek through your windscreen and see where the dial is set.
I wonder if it works for vehicles with no read/side windows ?
What do you expect from a guy whose handle is "k0osh.CEOofCLIT"?
"Hi! It looks like you're using your PDA, would you like some help?"
"Hi! It looks like you're trying to listen to the radio, would you like
a. A step-by-step guide on listening to your radio.
b. A radio tutorial.
c. Continue using the radio.
And voila, radio dropouts every few minutes on all highways!
What makes a man want to be a mouse? (Python's Flying Circus)
I drive this section of the Cap City freeway quite often (used to be several times a day, now it's a few a week), and I couldn't tell you how many times I've inched past this spot at about 5MPH. So what happens to this thing when you've got six lanes of traffic inching by, and they're all listening to different things?
:\
Of course, my biggest concern is wrecks. This particular spot is already a popular wreck site, with the Garden highway exit, the CalExpo grounds (location of the yearly state fair and dozens of other big draws), the way too narrow for its capacity American River Bridge and curve, and one of the biggest shopping malls in the region all located off of this short stretch of overcrowded highway. The LAST thing this spot really needs is another visual distraction
There is nothing so pathetic as seeing a beautiful young theory roughed up by a tough gang of facts.
OK, I know very little on the subject, so I want to know if it would work to shield the radio, but not the antenna. Would the internal frequency it still leak "back up" the antenna? Could you extend this in some way so that it wouldn't? (Second, unshielded receiver box, sending a "shielded" signal to the receiver/decoder/whatever.) I mean (given you're paranoid enough) you could probably make a box to encode the whole signal digitally and send it encrypted to a shielded box for digital processing. If you were desperate.
(And for those who say "who cares, why be so silly over such a small thing"... well, it might not matter now, when your radio station of preference is being monitored, but at some point, it will. That's when this knowledge becomes useful.)
Don't think of it as a flame---it's more like an argument that does 3d6 fire damage
Lets think for a moment.. My radio emits RF leftovers. "They" can pick up that information, process it, and then market to me based on that knowledge for money. Thank goodness. I can now passively sniff WiFi all day long. Or is this not a two way street?
...
My CRT emits RF. What happens when they can pick that up? Think thats far off?? Okay, what about WiFi? Can I write a program to sniff the 30-some odd WiFi hotspots in my neighborhood.. and based on their physical location and the data I gather, market too them? Why or why not??
Think the analogy doesn't apply? What about the sattelite internet that uses sattelite downlink and landline uplink.. that is broadcasting to all of north america.. more than any single radio station.. This could set a dangerous precedent, no?
Oh, for a room with a view of the sign, a tunable Gunn oscillator, and a reflector to beam my signal at the sign.
Hours of fun, convincing the sign that everybody leaving the football game is listening to a PBS classical music station.

To the parent troll: your friends can keep modding me down, and I can keep reposting the truth over, and over, and over. I've got more karma than you have mod points, and once people take a look at this for themselves, you're going to start getting modded down. If I'm wrong, post a followup and tell Slashdot why I'm wrong, because trying to prevent my posts from being read isn't going to work.
Here's the content that was suppressed:
Aren't you the guy that claimed that you were head of Nintendo R&D, and then had someone else (a few articles back, IIRC) point out that they knew the person in charge of Nintendo R&D and that you weren'thim?
Furthermore, you've been giving what you claim is inside information about Nintendo on Slashdot, which I can hardly see the head of a corporate R&D division doing. I've worked in corporate R&D, and they're quite secretive, -- and more so the higher they get.
Finally, the heads of Nintendo's two R&D departments are, according to Planet Nintendo, Takehiro Izushi(R&D section 1) and Kazuhiko Taniguchi (R&D section 2). There is no "Nintendo Advanced R&D" division that I could find any reference to, nor is the informal term "head" a title that is likely to be used in the formal Japanese corporate culture. Finally, I find it rather unlikely that a non-Japanese person such as yourself would hold such a high-ranking position at a large Japanese firm.
Finally, I find it beyond belief that the head of "Nintendo Advanced R&D" would beg on Slashdot for details of how modchips work, when there are engineers aplenty that have worked hard on exactly this problem present in hordes working in Nintendo's R&D departments.
Sir, I accuse you of being both a troll and a fraud! To the Foe list with you!
And, sir, I must say that I find your claim in your User Bio that you earned three PhDs in three years highly unconvincing.
May we never see th
[the doorbell rings]
Mike: That'll be the front door.
Neil: I bet I know who's got to answer it.
Mike: But, Neil - you like meeting people!
Neil (to camera): If I had a penny for everytime I had to answer the door, I'd have five pound sixty three!
[Neil gets up and goes to door]
Vyvyan: It's probably someone unbelievably boring!
Neil: Oh, no! It's the TV Detector Van!
Rik:MIKE, YOU BASTARD! Why didn't you buy a licence? I can't go to prison! I'm too pretty! I'll get raped!
Mike: Yeah, steady on! Steady on! We're not beat yet! All right, the time has come for diplomacy!
Neil: Oh, no - he's asked me if we've got a telly! I think I'm gonna have to lie! Bad Karma!
Mike: All right - the time for diplomacy is over. Vyv?
[Mike unplugs the TV]
Mike: Chuck the telly out the window!
Rik: Get rid of it! Quickly! Quickly!
[Vyvyan picks up TV and throws it at the window. The TV bounces off the window]
Mike (to camera): That, I did not expect!
Vyvyan: What if we sneak it out past him into the street?
Rick (to Mike): Yes! Yes! Yes! Mike, you go out and point to the sky, right, and say, 'Look at that interesting thing up there!'
Rick (to Vyvyan): You disguise the TV as an old woman, and sneak it past him!
Mike: Rick, suicide may be a great hobby - but I wouldn't do it for a living!
Neil: Lads, I've told him we don't have a telly, and I think that's thrown him a bit - but it won't hold him forever!
Rik: Good thinking, Neil! Keep it up!
[Rick starts writing in a notebook]
Mike: This is a very tricky spot, but Mike - the cool person - will squeeze it! Rick, stop crying!
[Rick rubs his eye]
Rik: I'm not crying - I just got something in my eye, that's all!
Mike: Vyv? Eat the telly!
Vyvyan: That's a completely brilliant idea, Mike! I've been wanting to do this for a long time!
[Vyvyan grabs the TV and starts devouring it. Rick continues writing]
Rick (writing aloud to himself): (It was the other three, not me. I had no idea what was going on, it really was the other three!)
[cut to front door. Neil is talking to a man]
Neil: All right, don't rush me - that's not an easy question to answer. 'Have I got a telly?' There could be, like, a number of different replies. I need some time to think one up, you know?
Mr Bastard: We know you've got one - we detected it!
Neil: Oh - so you've just been playing with me all along?
Mr Bastard: Well, it's better than playing with yourself! Ho-ho! A cheap sexual allusion - makes the world go round!
Neil: Ugh!
Mike: Neil, you haven't introduced me to your new pal.
Mr Bastard: Bastard's the name!
[he shakes Mike's hand]
Mr Bastard: But you can call me 'Right Bleeding' - all my friends do. Or did.
Mike: What do you mean?
Mr Bastard: I killed him. Where's your licence?
Mike: As the eunuch said to Mussolini, 'I haven't got one - and if I did, I wouldn't show it to you!'
Neil: That was a really cheap joke, Mike.
Mike: I'm saving up to pay the licence fine.
Neil: Don't tell me you haven't got a plan.
Mike: (I could never resist a challenge.) Neil, I haven't got a plan.
Mike (to camera): I hope someone's taking this down!
[Mr Bastard shoves his way inside the house]
Mr Bastard: Right - where's this telly? Ah-hah! So you do have it! You little runt!
[he walks over to Vyvyan, who has successfully eaten the TV, save for the cord, which hangs out his mouth. Vyvyan waves to Mr Bastard]
Mr Bastard: The old trick, eh? Eat the telly before I get a chance to nick you!
Vyvyan: It's a toaster!
Mr Bastard: It's a telly, you yobbo! Now give it back - I want to nick you!
[he grabs Vyvyan's hands, puts his foot on Vyvyan's stomach and pulls. Mike quickly intervenes]
Mike: Mr Bastard! Mr Bastard! OKAY! Now, toaster or telly, the contents of my colleague's stomach are private property! And if they get damaged in any way, we sue!
Mr Bastard: Well... I can wait! I've dealt with your sort before!
Mr Bastard (to Neil): Where's your toilet?
Neil: Oh, upstairs. Just follow your nose.
Rik: That's just great, Neil. Tell the fascist where our toilet is!
Neil: Shh!
Mr Bastard: I'm going up there now, to wait. I know how to wait! And I promise you, son - when that telly comes out the other end, you're nicked!
[he slowly slinks up the stairs, then comes back and looks at the bomb for a second, the ascends the stairs again]
Vyvyan: It's all right, lads - I always poo before I get up!

Because, as everyone knows, driving down the highway without reading all the billboards is stealing.
Kind thoughts do not change the world
Methinks the billboard company is gilding the lily a bit. Tools to forecast driver consumer preferences already exist, and they're no less accurate than electronically peeking at your radio dial.
Animated boards are expensive. That means the outdoor company will only be putting them in high-traffic locations.
Hundreds of cars might pass the board in a one-minute period. It takes about four seconds to absorb a well-contructed outdoor display. Obviously, the data isn't going to be targeted at individual motorists. It'll be an average of traffic flow over some given period of time.
That makes the radio tuner data much less useful. All the billboards will be doing is determining localized listening preference. I gotta tell ya: it ain't gonna be much different than the Arbitron radio ratings already available to the industry.
Properly programmed radio stations have very predicatable listener compositions. Take a Classic Rock station, for instance: the typical listener will be between 35 and 49 years of age. He is 70% likely to be male. He is about 45% likely to be married.
You can take this further, computing the possibility he has kids and his approximate ages. More importantly, you can interpolate this data against retail databases which qualify the likely incomes and buying habits of people in these demographic cells. There are plenty of industry tools which do this, such as Scarborough Research's databases.
That's how the billboard companies will pitch their clients. They'll merge the radio listening data against something like a Scarborough study and--boom--we can see that a certain number of drivers during a given hour will make a car purchase within the next month. The billboard chooses a Chevy ad. If you know where most of the traffic is heading, you can even tag it with dealer info. Awesome.
But the billboard company really doesn't need the gee-whiz realtime radio snooping. It's a gimmick. Their sellers can already work out the data with existing desktop tools.
Imagine that: hype from advertising execs. Who would have figured?
