Now we’re going Places

Filed under: geotagging, gps, lbs, local search, maps, mobile, social networking, twitter — Tags: — Rocky Agrawal @ 1:59 pm

I’ve been writing about Twitter and location since my first post about Twitter in 2007. This week, Twitter launched Places, which allows users to add their location to a tweet.

Here’s a screenshot from 2007:

and today:

Embedding location in a tweet in 2010

In 2007, I used a third-party application from Where to include my location. Clicking on that link would take you to a map on Where’s site showing the address. (The link in the original post no longer works.)

With the launch of Twitter Places, the search is done within the Web browser (and soon in Twitter’s mobile applications). You can select where you are from a list of nearby places. Clicking on the place name brings up the map above and the option to view tweets about that place.

Although the difference between the two may seem subtle, they are significant:

  • Because the place is metadata, it doesn’t count toward the 140 character limit.
  • Place names are human readable, unlike addresses and latitude/longitude. Knowing the name of a place makes it much easier to find than just a street address, especially in dense metropolitan areas.
  • Places are unique to a specific venue. Doing a pure location-based search would return tweets from surrounding businesses or businesses that have since disappeared.
  • Integration in to the main Twitter experience means broad exposure and eventual standardization of place identifiers. That has been a longstanding challenge in the local space.

Twitter’s geo APIs have been available for several months and third parties like bing have created interesting applications like Twitter Maps. With the availability of places across the Twitter platform, we can expect to see more interesting applications including both real-time applications (ride sharing and ticket exchanges) and historical (restaurant reviews, past events).

Once Twitter allows owners to claim their Place and associate it with a Twitter account, we could see official tweets of announcements and offers incorporated into a Place’s search results.

When pictures are tagged to a Place (instead of a lat/long), we’ll have the ability to visually browse a venue in Twitter.

Tellme where you want to go today

Filed under: dash, gps, launchpad, satellite navigation, search — Rocky Agrawal @ 10:06 pm

I’ve written a few times about Dash Express, the next-generation navigation device from Dash Navigation. It’s the world’s first two-way connected navigation system. That connectivity allows for some amazing features.

We launched one of those today at Tellme. Dash users who call 1-800-555-TELL or 1-800-CALL-411 and do a business search will have the business listing sent automatically to their Dash device. The listing arrives almost instantaneously. It looks something like this when it arrives:

A few clicks and your Dash will give you turn-by-turn directions to the business you selected. This solves a real need: using the power of speech to make entering businesses much easier.

We’re doing lots of exciting things in the automotive space. I’ll share them as they launch.

More about this on the Dash blog.

How long does it take to get from Pike Place Market to Mount Rainier National Park? According to Google Maps, it’s a 5 minute walk; less than 1/3 of a mile. Pretty easy, huh?

Mount Rainier looks an awful lot like an office tower to me.

Mount Rainier looks an awful lot like an office tower to me. That'll be one steep climb!

In reality it’s a 2 1/2 hour drive.

This error is the result of a fundamental challenge in how data is collected for online navigation and local search products: all of the major services use data that weren’t originally collected for navigation. The typical source is phone books listings, which were originally compiled by companies like InfoUSA to sell mailing lists. In this particular case, the national park likely has a business office in Downtown Seattle.

Einstein monumentThe data have a distinct bias: toward places with phone numbers. While you can get exact driving directions to a local ball bearing distributor, look for a park, landmark or trailhead and you’ll often get erroneous data or no results at all. Occasionally, you’ll luck out and there will be business names nearby that incorporate the place name.

Just for fun, try finding the Albert Einstein statue in Washington, DC using an online mapping service. (If you can’t find it, click on the image to see the answer.)

On Sunday, I was looking for Hippie Hill in Golden Gate Park. Yahoo! Maps struck out entirely. Mapquest delivered a bunch of unrelated results.

An answer lies in another Yahoo! property: flickr’s database of geotagged photos. Although flickr’s search tools aren’t optimized for local search, it’s content is a great data source. The first search result in Google Maps for Hippie Hill is spot on; it came from Google indexing flickr’s geodata. The commercial results on the same map (the red markers) are mostly garbage.

Flickr is just one tool. As more people adopt GPS-enabled phones like the iPhone, we’ll see more and more user generated data. Enabling mobile data collection is reason enough to build an iPhone app.

Developing countries have the potential to leapfrog the developed world in data quality. Google’s Map Maker allows anyone to populate data in countries without large commercial data providers. You can pull up a satellite view and trace roads. Zoom into buildings and add local businesses. Find a park and add in key features. Because the content is user generated, the places that people look for the most will be added first, as opposed to the local ball bearing distributor. Places with colloquial names will become findable.

User-generated content has its challenges, of course. In the initial stages, tools like Map Maker will attract the community organizers who are passionate about their neighborhoods. Once the data start getting even modest usage, spammers will attack. But many of the standard spam fighting techniques can be used to deter them.

OpenStreetMap and Wikimapia offer similar functionality. OpenStreetMap is focused on creating and editing roads; Wikimapia is focused on places of interest.

Google Map Maker’s user interface is more intuitive than OpenStreetMap and Wikimapia. Unfortunately, Google is being hypocritical in how it treats the data. While Google Maps combines data from other sources, such as indexing geodata from flickr,  it is keeping content generated by Map Maker users locked up. Users can’t even download the data they create.

I am here, where is everyone else?

Filed under: apple, facebook, flickr, gps, im, instant messaging, iphone, lbs, mobile, social networking, twitter, where, yelp — Rocky Agrawal @ 12:02 am

Since the iPhone app store came online, I’ve been playing with a number of mobile social networks. There’s no shortage of them: Limbo, Loopt, Where and Whrrl are all attempting to play in the space.

The central idea of mobile social networks is to connect you with your friends while you’re out and about. Unfortunately, they all require you to rebuild your friend list. Early versions of the Loopt app went so far as to spam people in your iPhone’s address book with text messages.

Local events on Where

Local events on Where

Here are some of the keys to success in mobile social networks:

  • It’s the network, stupid. Getting people to create Yet Another Network won’t work. I’ve already created my network. Use it. My only friend on the iPhone version of Loopt is 2,500 miles away — hardly someone I can run into when I’m out in San Francisco on the weekend. Loopt and Where have Facebook apps, but their iPhone versions don’t seem to tie into them.
  • Let me control when I update my location. Location is very personal. Don’t automatically update my location just because I’ve launched your application. I may just want to check something.
  • Let me publish beyond your app. Early adopters who try your app are willing to accept that there is a ramp up period, but they aren’t going to do work for zero return. If I my update my status and no one is there to see it, have I updated my status? Let me automatically publish the information I collect using your app to Facebook, Twitter and my blog. Not only does it give me a reason to use your app, it becomes a distribution vehicle for you, providing exposure to my friends who just might say “How’d he do that?” I taught a lot of my friends about Facebook mobile simply by updating my status from my phone. (Facebook puts a mobile phone icon next to such updates.)
  • Seed your app with other content sources. If I don’t have friends, at least give me other content that makes your app worth using. Where does a good job of this, pulling in content from Yelp, eventful and Zipcar. If you can, get ego bloggers like Scoble to use your app.
  • 128 King St is not a place. Pete’s Tavern is. Whenever posting information, it should include a human understandable version. You’d never post a location of 37.778911, -122.391223; a street address is marginally more helpful. With the margin of error built into GPS and density of urban areas, place names are critical.
  • Let me take pictures. For a long time, mobile developers haven’t had access to cell phone cameras. With the iPhone, they do. The ability to take and send a picture makes it easier to communicate a lot of information quickly. And it adds life to your application. (Bonus points for dropping a copy of the picture in my flickr account.)
  • Tie into IM and SMS. Loopt claims that the most commonly asked question via SMS is “Where are you?” That claim is probably made up marketing b.s. without any hard data. Nevertheless, it is a frequent question. Make it easy for me to answer it. Let me send an SMS or IM that includes where I’m at (Pete’s Tavern, 128 King St.). To anyone. Include a URL with a map and optionally a picture.
  • Don’t spam my friends. What you do with my friends’ contact information reflects on me. If you spam my friends, I will never use your application again. And I will tell everyone you’re a spammer.

Tying into the various APIs I mentioned may seem like a lot of work — and it is. But the alternative is spending a lot of money on distribution and marketing.

Unlocking the creativity of the masses

Filed under: apple, apple tv, facebook, flickr, geotagging, gps, iphone, ipod, lbs, local search, mobile, mobile search, photography, social networking, twitter, where, wireless, wireless data, yelp — Rocky Agrawal @ 9:26 pm

With the launch of the iPhone last year (and the millions of dollars in ad spend around it), Apple did more for wireless data adoption than wireless carriers had in the last 10 years. With Thursday’s launch of the App Store, they’re doing it again by unlocking the creativity of the masses.

Wireless carriers had long held on to core cellphone features with an iron grip. Want access to the camera, GPS, microphone or address book? Good luck. It usually involved spending a year or more negotiating with a carrier and then writing and (rewriting) your app to work on dozens of phone models. And when you were all done, you brought it to a market with little distribution support at a price few people would pay.

In the last couple of days, I’ve downloaded more apps than I had in my entire history of cell phone usage (dating back to 1996). There’s one big reason: once developers had access to features like GPS and the camera, they created compelling applications.

The most compelling apps have come from independent developers or startups. Some have used public APIs for other products; although there isn’t an official flickr app, there are several apps that interact with flickr. AOL is the lone exception among large companies, with apps for AIM and AOL Radio.

Here are some of the apps that caught my eye. With the exception of iMilk, all are free. That’s another refreshing change: Apple is making it easy for application developers who want to distribute free applications. Even paid apps can be relatively cheap, with a one time price of $3-$10 being common. (Versus the previous $3-$5 per month.)

All is not perfect in app land, of course. Much like when Facebook launched their app platform, some developers are having a hard time keeping up with the demand. I’ve also had my phone reboot at least half a dozen times when using various apps.

The functionality in some of these apps is limited compared with their other incarnations. For example, in Jott, you can’t send Jotts to others. As these apps are revved, they’ll become even more compelling.

Jott

Jott allows you to record a voice “note to self”. The note is then transcribed and put in your Jott account, which is available by phone or Web. It isn’t as robust as Jott’s

Where

A mobile social network that lets you plot friends on a map, look for restaurant reviews, find and reserve Zipcars and even look at a map of the night sky where you are with the constellations plotted. (Video of the app.)

There are a number of players looking to create mobile social networks. Whrrl, Loopt and Limbo offer somewhat similar apps. Where offers a range of features beyond social, while Limbo is the most social.

(Disclosure: I did some consulting for Where last year.)

Facebook

Facebook took an early lead with the iPhone 1.0 by having one of the best iPhone optimized sites. The lead developer released a toolkit that was used by other developers. The application version adds the ability to upload photos and IM, but lacks some of the features found in the browser version.

AirMe

Upload pictures to flickr (or an AirMe account). The pictures are automatically geotagged with your location. AirMe also tags you pictures with the current weather conditions.

NearMe

See pictures from Panoramio of places around where you are.

Twittelator

See and update Twitter. Post pictures and location updates. Twitterific has less functionality and also has ads.

Urbanspoon

Kind of like a Magic 8 ball to decide where to eat. Uses GPS to find where you are. Shake your iPhone and it will select a place for you.

iMilk  ($2.99)

“Drink” virtual milk. Uses the iPhone’s accelerometer to empty the glass. If you prefer, you can pour it into a glass before drinking.

Remote

Control your Apple TV or iTunes. Play songs, see album art and search your iTunes library. Works over Wifi, so you don’t have to be in line of sight. Much better than the flimsy remote that ships with Apple TV.

Pandora

The world’s greatest music discovery service now streams to iPhone. The app is beautifully simple. Add in an aux in jack or FM transmitter for your car and say goodbye to the $14 a month you’re paying to XM or Sirius.

Yelp

Why settle for the hand-picked (usually glowing) reviews displayed in the restaurant window? Pull out your iPhone and check Yelp. My favorite feature is a filter that limits the search to restaurants that are open now. Very helpful for those midnight cravings.

Occasional reader – cognitive surplus, Larry Page on changing the world, CSI and mapping crime

Filed under: apple, dash, google, gps, iphone, microsoft, reader, satellite navigation, television, video, weekly reader — Rocky Agrawal @ 8:46 pm

Some interesting reads from the last few weeks:

  • Clay Shirky at Web 2.0 Expo on the cognitive surplus (Web 2.0 video) – Author Clay Shirky spoke recently on how much could be done if only a fraction of the time spent watching TV is put to other uses. He estimates that 2,000 Wikipedias could be created with just the time Americans spend watching TV in a year. (I just clicked off the TV to write this post.) While Shirky focuses his talk on production of content, all that production also has a significant effect on consumption. Time is a zero-sum game. The time I spend on Facebook or reading about Jon’s exploits in Russia is time I’m not spending with TV or traditional media. And for every producer, there are at least 10 to 20 consumers.
  • Larry Page on how to change the world (Fortune) – Google co-founder Larry Page lays out the challenges we face in changing the world. The core problem is that not enough people and companies take risks. Part of this undoubtedly is due to the risk/reward systems in most companies. Innovation (and the people who chase it) are often the first to go when belts need to be tightened.
    I was at a conference last week where Erik Jorgensen of Microsoft demoed some amazing technologies in mapping, such as 3D map tours. A questioner from the audience, a Microsoft shareholder, asked what the ROI was. Fortunately, Microsoft and Google do well enough in their core businesses that most investors give them the freedom to innovate.
  • ‘CSI’ sleuths out Microsoft’s latest technology (USA Today) – CSI:NY producer Anthony E. Zuiker is teaming with folks at Microsoft labs to bring bleeding edge technology to viewers. (And no doubt frustrating real life criminalists with increased expectations.) Last week’s episode featured Microsoft’s Photosynth technology. CSI:Miami used variations of Microsoft’s Surface computing. Microsoft isn’t the only one in the CSI product placement game; many of the pictures processed by the Photosynth technology in that episode were taken with iPhones.
  • Honda system to warn motorists of crime hotspots (AFP) – In-car navigation systems and PNDs are getting more data rich all the time. On recent Acuras you can get Zagat ratings. With a Dash Express PND, you have access to Yahoo! Search results. Now, in Japan, your Honda can tell you when you’re in a dangerous neighborhood. I suspect that fears of redlining and disparate data sources will keep that from happening here. But I wouldn’t be surprised if some enterprising Dash users use create and share localized feeds for such an app.

Some interesting reads from the last few weeks:

  • Wall St. Journal Makes Politics Its Business (Washington Post) – Media critic Howard Kurtz takes an in-depth look at changes at the Wall Street Journal since its takeover by Rupert Murdoch’s News Corp. The biggest change is the increase in political coverage amid one of the most interesting political campaigns in recent history. The Journal, a rarity among newspapers, is increasing its news hole thanks to its new benefactor. via Howard Kurtz
  • Steered Wrong: Drivers Trust GPS Even to a Fault (WSJ) – For all their convenience, portable navigation devices and online mapping still have one big problem: the world’s road network is constantly changing and digital mappers can’t keep pace. Some countries in Europe even have signs at tricky intersections telling drivers to ignore their GPS’ instructions. Yet many drivers put their faith in technology and blindly follow their GPS’ instructions. Perhaps this is because their accuracy is oversold; a TomTom TV ad (see below) shows a couple driving across a bridge during the ribbon cutting ceremony. The typical map on a PND is a year old the day you take it out of the box. via Doris Truong
  • Eating away the innings in baseball’s cheap seat (USA Today) – What’s more American than baseball and Cracker Jacks? Possibly stuffing yourself silly. Faced with anemic attendance, some teams have come up with a new way to generate revenue: all-you-can-eat sections where you can eat all the hot dogs, french fries and soda you can stomach. At the Braves’ Turner field, the “typical all-you-can-eat customer downed: 3.35 hot dogs; one 20-ounce soda; one 7.9-ounce bag of peanuts; one 3-ounce order of nachos and 32 ounces of popcorn.” In unrelated news, the average seat at the Mets’ new Citi Field is 21 inches wide, 2 inches wider than those at Shea.
  • IRS making sure your rebate gets spent (Marketplace) – One of the big concerns about the “economic stimulus” package is that people will do something silly with it — like save it or use it to pay down debt. I suggested that the rebates be issued as VISA debit cards. Apparently the IRS is using lifestyle analysis to determine what taxpayers want and spending their $600 rebate checks for them. One couple received an air conditioner instead of the check they were expecting.

Picking the wrong default path

Filed under: consumer electronics, geotagging, gps, product management, ui, usability — Rocky Agrawal @ 10:09 pm

I’ve been using my Garmin eTrex Vista Cx GPS for six months. I use it when hiking and to geotag pictures. I noticed that I haven’t been getting the advertised accuracy level; the accuracy has ranged from 25 to 150 feet.

The Garmin Web site touts the benefits of WAAS:

A WAAS-capable receiver can give you a position accuracy of better than three meters 95 percent of the time. And you don’t have to purchase additional receiving equipment or pay service fees to utilize WAAS.

What a deal! You just don’t get that out of the box — Garmin defaults WAAS to off. Once I turned it on, accuracy improved to 8 to 10 feet.

Garmin isn’t alone in shipping crippled products; many of the products and services we use come to us less than advertised. There are a number of reasons for this:

  • Money. Computer manufacturers such as SONY and Dell lard up PCs with crapware like toolbars, trial versions of antivirus software and offers for broadband access. Companies like AOL, Google and McAfee pay for this distribution. It’s the price of cheap PCs. SONY recently received a lot of bad press for offering a “Fresh Start” option, which allowed consumers to buy select laptops without crapware for a $50 premium.
  • Shelf appeal. TV sets are preset to look good on the big, bright showroom floor. These settings aren’t optimal in a smaller, darker environment.
  • Support costs. Despite the fact that they all touted security as a key feature on the box, every wireless router I’ve had has come with security turned off. This isn’t the right choice for most users, but it is the one that will work out of the box and is least likely to trigger expensive customer support calls.
  • Server capacity and operational costs. Gmail offers all users the ability to use a secure version of email, but defaults to insecure. Just go to “https://mail.google.com” and your entire session will be encrypted. Or use the Better Gmail extension to always force an encrypted session.
  • The right choice for the user. Sometimes default decisions are actually based on what most users would want. Things like language, time display format and currency symbols frequently fall into this category.

It’s hard to tell which of these apply in the Garmin case. Clearly, users wouldn’t prefer data that is more inaccurate, unless there was some downside to having more accurate data. I might take less accurate data if it meant I got more battery life in exchange. The Garmin owner’s manual is silent on this topic, although it does mention other factors that affect battery life such as backlight usage.

WAAS requires more computation, so maybe it makes the unit slower? Again, the owner’s manual is silent on this.

Garmin ignores the fundamental question I always ask when giving users a choice: does the user have the information necessary to make that choice? In this case, clearly not. There’s plenty of space on the Garmin’s screen (see picture below) to explain the impact of turning on WAAS.

Judging from a GPS-fan Web site, it looks like there’s no reason to turn it off:

On the current generation Garmins, there is no discernible impact on speed or battery life with WAAS on.

Which begs the question: if there’s no negative impact, why not have it always on and remove the option?

Disclosure: I was part of the team responsible for AOL Toolbar distribution on SONY PCs.

Dash-ing out of the gate

Filed under: cars, consumer electronics, dash, gps, local search, maps — Rocky Agrawal @ 12:31 pm

Dash PNDThe Dash portable navigation device I wrote about earlier is now shipping. Dash has dropped the price $200 from the initial pre-order pricing.

It’s the first true two-way connected PND on the market, using cellular data for search, traffic and community features. Because I now work on automotive products, I’ll pass on reviewing it. The initial coverage from Walt Mossberg and The Washington Post are very positive. The Post story also goes into depth on how traffic services work.
