Google Now grabs information about you from Gmail, Google Search, and elsewhere, and uses that data to improve results.
Lately, Google has folded in some amazing capabilities. For example, it preemptively feeds you information about your car rentals, public transportation information based on guesses about where you might want to go, movie tickets and sports scores.
Google Now tells you more information about whatever's on screen. It knows what you're watching because, with your permission, it listens to the sound of the show to figure out what you're watching.
Google Now is great in every way except one-it doesn't give you enough information. Leaving Google Now running gives you a mostly static view, with "cards" coming in very infrequently.
Field Trip, another Google product, is wonderful only because of what it promises, not what it delivers.
Field Trip has the right idea, popping up contextual data. However, these are based on a list of arbitrary database-oriented websites, such as "Historic Detroit," "Public Art Archive," and "San Francisco Architectural Heritage." Unless you're in a major city, Field Trip contextual information is slim pickin's.
Balance privacy and assistance
There are other services that claim to interrupt with contextual information. But in my experience these require launching the app and refreshing it-a conscious choice followed by deliberate action, which is the opposite of what's promised in this category-interruption.
Looking at these few examples, the industry overall seems hesitant, unwilling or (most likely) unable to meet the promise of interruption for contextual information.
It's true that this category is fraught with hazard. People feel their privacy is being violated when a gadget demonstrates what it knows about them. It's an irrational concern because not letting the user take full advantage of harvested data (as is the case today for most users) doesn't equal privacy, just ignorance.
Users might get overwhelmed by too much interruption data. But there are better ways to stop overload than simply withholding messages. Let it be turned up gradually. Offer a snooze feature. Set times of day. Notify only when moving.
The ideal service would combine the benefits of Foursquare, Google Now and Field Trip. It would give you useful and interesting data not just for general areas or historic landmarks, but down to the specific address level.
It would be like the test version of Foursquare, interrupting you whether the app is running or not.
It would be like Google Now with its uncanny ability to know all about you and learn from your actions.
