UPDATE: See comment from Google at the end.

Users of Blackberries and many other smartphones can now push a button and the Google mapping service will figure out more or less sort of where they are.

Last month, I wrote a post called "One Reason We Need a Google Phone: Free GPS." I was complaining that cellphone carriers, mainly Verizon, are disabling the GPS navigation systems built into phones so they can charge $10 a month for the service. I posited that a Google phone wouldn't have such a nasty gotcha. (Actually, in Google's very open model for its Android operating system, carriers and phone makers are free to put as many gotchas as they want into phones.)


1

Google today is adding a feature for some smartphones that don't have built in GPS but can read the unique identifying number of the cell tower they are connected to. By using this information, Google can display a map of the general area they are in. (Google isn't the first to try this sort of thing.)


2

Google nicely tried to design the service to take into account its limitations. When you push the button, it draws a dot at the nearest cell tower and draws a circle around it to identify the area in which it thinks you are. The screen will tell you the margin of error, typically between 500 and 2000 feet.


2

Google sent me a Blackberry to try this out. (My cheap Times-provided Samsung isn't nearly smart enough to perform this trick.) A test on a bus trip from suburban New Jersey to midtown Manhattan shows that Google's system can generally figure out what neighborhood you are in, but it overestimated its own accuracy. I was often just outside its margin of error circle. Most comically, it insisted I had arrived in New York for the 20 minutes I was stuck in the Lincoln Tunnel. Anyway, this is a nice modest tweak to the service that will help people who are totally lost, but it's not going to provide real-time driving directions.

I spoke yesterday to Steve Lee, the product manager for Google Maps for Mobile, and I did learn a few interesting tidbits about the service.


3

First, Google figures out which cell towers are where by secretly enlisting the help of a million of its mobile maps users who happen to have phones with built-in GPS devices that are not locked by the carriers (that means no one who uses Verizon). These phones have been reporting to Google where they are, based on the GPS data and what cell tower they are connected to.


1

Before I even asked, Mr. Lee told me that Google had thought through the rather creepy privacy implications of all this. Google's standard approach is that it logs everything it does by the unique cookie of an Internet browser (or the equivalent unique ID of a mobile phone). For the location information from GPS and cell towers, Mr. Lee said, Google has built a database with not a bit of personal user information.


3

When pressed, however, he also admitted there is a loophole to this. The payoff for Google from building out its mapping service is to get people to conduct searches from their cellphones. This is a nice feature. Push a button on the map software, type "Starbucks" and it will display a map of the closest source of a latte fix, based on the cell tower or GPS data. The catch, is that this query, with your location, is entered in Google's log files along with your phone's unique ID.
For almost everyone, this won't matter. But if your location is really a secret, don't ask Google to help you find coffee.

UPDATE: Barry Schnitt, of Google's PR department, wrote with some clarifications. The service, he said, is in beta and the accuracy will improve as it is used. He took issue with the word "secretly" about how Google gathers the GPS data because such use is disclosed in the privacy policy of the service. And he also doesn't like the headline that implies that Google has a good guess where you are. Google, as the item says, knows your cellphone's ID number but not your name. (That is unless you use a service that requires you to log in, say Gmail for cellphones.) Mr. Schnitt's entire note is in the comments below.

UPDATE 2: Mr. Schnitt wrote back to say I was wrong and that the unique ID used by the Google Maps system can't be connected to any ID for GMail, which uses a separate application. So unless the map application starts to ask you to identify yourself, Google doesn't know where you are.

I know we’ve already looked at this article a bit, but this is mainly about familiarizing ourselves with this tool.

Try to make more detailed observations about the text and the argument–that is what this tool is for.

Aldrick on whole page :

The use of diction in the title of article is quite good, its an attention grabbing title that plays on everyones’ fear, that is their privacy being invaded, basicly this title appeals to pathos. The title has an effect of making readers read more about the “creepy” topic. Also, the title provides the audience the author’s personal view about the touchy subject, by the sound of the title “Google Doesn’t Know Where You Are (But It Has a Good Guess)” it clearly indicate that he is opposed to Google’s new service.

Gena :) on paragraph 5:

In this paragraph, Hansell uses a logo’s style of writing. It’s mostly informational to give the audience all of the background to the article. Hansell also explains that Google is not the only company trying to track people by their cell phones.

Kaitlin on paragraph 3:

Hansell states his claim in this paragraph. The rest of his article is focused on that particular claim. If he hadn’t told his audience what he was going to talk about, then the rest of the essay wouldn’t have made sense.

Colleen on paragraph 9:

It seems that Hansell uses parenthesis a lot in this paragraph and others in order to further back up his opinions without having to write out another complete sentence

December 3, 2007 4:13 pm

Remember, the first one won’t show up until I’ve gotten home and accepted your comment for the first time. Now that I have, you should be good. I’ll delete two of these for you.

Andrea on paragraph 7:

I was very confused as to why Hansell would put “(My cheap Times-provided Samsung isn’t nearly smart enought to perform this trick)” after the first sentence of the paragraph. However, I realized that it made me laugh. The tone and language he uses in that particular sentece is very satirical. He is trying to connect to the audience, or rather, he is trying to gain their attention by using such a tone, thus, also establishing ethos.

December 3, 2007 5:50 pm
Danielle on paragraph 7:

As in other places in the article, Hansell uses the small anecdote about his phone “[insisting] [he] had arrived in New York” to make himself more identifiable to the audience. He uses humor from the anecdote as well as his own personal experience with the subject on which he is writing to help establish his ethos.

Mary Kim on paragraph 9:

It seems that Hansell wants to have the motive to like Google’s idea, but it is not the greatest for getting directions.

Sam on paragraph 8:

It’s a short paragraph but it gives off a lot of information. For one, the information he is telling us is fresh (meaning recent). Obviously he knows that the people (readers) want the newest bit of information, just like they want the newest phone or to have seen the newest episode of Heroes. After that gives his information some ethos by stating how he talked to basically the man in charge of the whole project, which also gives him ethos getting the best information for his work. Finally he talks about “interesting” things he learned. Making us (the readers) ask “What information?” which hooks us like fish on a rod into reading the rest!

December 3, 2007 7:28 pm
Sam on paragraph 10:

Basically he’s pointing out that Google is really open about how they track you, but they are probably only open about it because if they aren’t then that makes them seem like they have something to hide, but Mr. Lee made sure to point out that they don’t have your personal information. Though the author Saul Hansel still puts Google in a creepy position, literally, by putting the Google and creepy near each other it makes Google have a bad vibe.

December 3, 2007 7:29 pm
Sam on paragraph 11:

His talk of “loopholes” “the catch” “query” “secret” makes Google seem like the Italian Mafia or a cars salesman. Not the good ol’ honest or trust worthy people we‘d like to think they were. As if they’re watching your every move so they can hook you for more money- pure evil! This makes us question whether we should use this feature of our phone, or Google at all. Since now we know that Google may not know WHO we are, but they know WHERE we are and are logging us down. Which is in fact the whole point of this story- creepy. He does very well at making Google look creepy in this paragraph.

Alix White on paragraph 4:

This paragraph addresses a common misconception: our favorite online sites are out there to help people, not make money. Well, I’ll remind you all Google is a company, so they’re always looking for ways to make money besides through ads and “renting” links through their site. If they have a brilliant idea like the Android system, why wouldn’t they try to make a couple bucks?

Alix White on paragraph 6:

This is an engenius idea; it reminds me of how people pinpoint earthquakes based on their magnitudes at three different places and the actual magnitude. It could be honed and become more accurate, but this way it’s helpful without seeming stalker-like.

Junho Lee on whole page :

The passage mainly calls upon the power of Pathos, using diction and reasoning to call upon the shock and dismay of the audience. Words like “nasty”, “creepy”, and “privacy” make the audience feel unsettled and fearful about this strange, intruding technology. A good argument based mainly upon Pathos.

Alycia Davis on paragraph 11:

The word choices he has through out this paragraph and the whole article is one that gives off an almost eery feel. Words such as “secret” and “loophole” help to make this effective. I think it’s also an ingenious idea to help make someone elses life easier while helping the company.

Ariel Mitchell on paragraph 4:

This is a great comment. I never thought of that. She did seem rather trusting in Google with out a reason to, but than again, I didn’t read her other article. Moreover, this could possible lower her ethos. It makes her seem that she is not knowledgeable in what she is talking about, leaving her audience to wonder if she is sure about her topic now. Though, this lack of confidence in her from her audience isn’t extremely significant because she uses some examples of her experience with Google’s gaget.

Jennifer Croak on paragraph 11:

The sentence he crossed out near the end was interesting because if he wanted for everyone not to see what had been previously written why not just delete it? why write it, corss it out, and decide to keep it in. I think he wanted everyone reading this to see that his original comment abou tbeing able to trace your indentification back to you through a login of an email account was still worth saying but he didnt feel it was justified now that the PR man had rebutted his statement.

Chase on paragraph 6:

I agree with Alix, he is making this statement to strengthen his point on the subject. It states what is in the title, Google doesn;t know where you are.

January 22, 2008 4:17 pm
Chase on paragraph 4:

I think that this is a cool idea by Google, and that there isnt much harm to it. But the way the author uses this information to strengthen the argument of how Google knows who you are and where you are is great.
