When you use Google Maps Navigation,

However, there's always been one problem: Once you're behind the wheel, a list of driving directions just isn't that easy to use. It doesn't tell you when your turn is coming up. And if you miss a turn? Forget it, you're on your own. moncler alpes jacket black Today we're excited to announce the next step for Google Maps for mobile: Google Maps Navigation (Beta) for Android 2.0 devices.This new feature comes with everything you'd expect to find in a GPS navigation system, like 3D views, turn-by-turn voice guidance and automatic rerouting. But unlike most navigation systems, Google Maps Navigation was built from the ground up to take advantage of your phone's Internet connection.Here are seven features that are possible because Google Maps Navigation is connected to the Internet:The most recent map and business data your phone automatically gets the most up-to-date maps and business listings from Google Maps you never need to buy map upgrades or update your device. And this data is continuously improving, thanks to users who report maps issues and businesses who activate their listings with Google Local Business Center.Search in plain English Google Maps Navigation brings the speed, power and simplicity of Google search to your car. If you don't know the address you're looking for, don't worry. Simply enter the name of a business, a landmark or just about anything into the search box, and Google will find it for you. Then press "Navigate", and you're on your way.Search moncler alpes jacket blue by voiceTyping on a phone can be difficult, especially in the car, so with Google Maps Navigation, you can say your destination instead. Hold down the search button to activate voice search, then tell your phone what you want to do (like "Navigate to Pike Place in Seattle"), and navigation will start automatically.Traffic viewGoogle Maps Navigation gets live traffic data over the Internet. A traffic indicator light in the corner of the screen glows green, yellow or red, depending on the current traffic conditions along your route. If there's a jam ahead of you, you'll know. To get more details, tap the light to zoom out to an aerial view showing traffic speeds and incidents ahead. And if the traffic doesn't look good, you can choose an alternate route.Search along routeFor those times when you're already on the road and need to find a business, Google Maps Navigation searches along your route to give you results that won't take you far from your path. You can search for a specific business by name or by type, or you can turn on popular layers, such as gas stations, restaurants or parking.Satellite viewGoogle Maps Navigation uses the same satellite imagery as Google Maps on the desktop to help you get to your destination. Turn on the satellite layer for a high-resolution, 3D view of your upcoming route. Besides looking cool, satellite view can help you make sense of complicated maneuvers. Street ViewIf you want to know what your next turn looks like, double-tap the map to zoom into Street View, which shows the turn as you'll see it, with your route overlaid. And since locating an address can sometimes be tricky, we'll show you a picture of your destination as you approach the end of your route, so you'll know exactly what to look for.Since there's nothing quite like seeing the product in action, we made this video to demonstrate a real-life example: The first phone to have Google Maps Navigation and Android 2.0 is the Droid from Verizon. Google Maps Navigation is initially available in the United States. And like other Google Maps features, Navigation is free.

Raman shares his tips on how to use Google from his perspective as a technologist who cannot see moncler alpes jacket green tips that sighted people, among others, may also find useful.The most recent release of Android 1.6, a.k.a. Donut, introduces accessibility features designed to make Android apps more widely usable by blind and low-vision users. In brief, Android 1.6 includes a built-in screenreader and text-to-speech (TTS) engine which make it possible to use most Android applications, as well as all of Android's default UI, when not looking at the screen.Android-powered devices with Android 1.6 and future software versions will include the following accessibility enhancements:Text-to-Speech (TTS) is now bundled with the Android platform. The platform comes with voices for English (U.S. and U.K.), French, Italian, Spanish and German.A standardized Text To Speech API is part of the Android SDK, and this enables developers to create high-quality talking applications.Starting with Android 1.6, the Android platform includes a set of easy to use accessibility APIs that make it possible to create accessibility aids such as screenreaders for the blind.Application authors can easily ensure that their applications remain usable by blind and visually impaired users by ensuring that all parts of the user interface are reachable via the trackball; and all image controls have associated textual metadata.Starting with Android 1.6, the Android platform comes with applications that provide spoken, auditory (non-speech sounds) and haptic (vibration) feedback. Named TalkBack, SoundBack and KickBack, these applications are available via the Settings > Accessibility menu.In addition, project Eyes-Free (which includes accessibility tools such as TalkBack) provides several UI enhancements for using touch-screen input. Many of these innovations are available via Android Market and are already being heavily used. We believe these eyes-free tools will serve our users with special needs as well.You can turn on the accessibility features by going to Settings --> Accessibility and checking the box "Accessibility". While the web browser and browser-based applications do not yet "talk" using these enhancements, we're working on them for upcoming releases. Check out this Google Open Source Blog post for more details, and stay tuned to the eyes-free channel on YouTube for step-by-step demonstrations on configuring and using accessibility support on Android
