Wednesday was the official day opening of Google I/O developer's conference 2012 and as the day proceeded the usual mad affair on the show floor began with a bang in San Francisco. As expected, the Android OS creator demonstrated loads of new software and hardware updates at the event.

The Day 1 got into full swing and definitely delivered more than what was predicted from the tech enthusiasts across the globe.

Here's a recap of all the spectacular launches that came through later on Wednesday by tech giant Google Inc.:

Android 4.1 Jelly Bean

Google announced that its various hardware partners have sold over 400 million Android-based devices, and that over 1 million Android phones and tablets are activated every day. In comparison, at last year's Google I/O, the company said that 100 million Android devices had shipped up to that point.

Taking it further, on Wednesday, Google announced the next major update to its Android operating system. After a year of success with the Android ICS (Ice Cream Sandwich) version, the company officially declared that their latest version is Android 4.1 Jelly Bean.

The news OS was informed to be coming in July with Project Butter, which is Google's attempt to make the entire UI "fast, fluid and smooth." It will include triple buffering in the graphics pipeline, to ensure consistent frame rates with interface animations.

Google's I/O demo also showed two Galaxy Nexus devices side by side, one running Ice Cream Sandwich and the other on Jelly Bean, with the latter offering a significantly higher frame rate when navigating the Android UI.

Hugo Barra from Android product management talked about the main theme of Android 4.1 Jelly Bean stating, "we (Google) want things to be simple, beautiful, and really smart." Some of the improved features of the Android 4.1 Jelly Bean includes the following:

Icon Arranging - This feature will allow users to move apps around the screen which is similar to iOS device.

Offline Voice Typing - With this users would be able to dictate their message or text even without Internet connection and the text would automatically appear on the screen. So far, it only supports the English language but it would soon be available in other languages.

New Audio Features - These new audio features would enable users, including people with disability (e.g., visually impaired) to maximize their Android-based devices.

Other additions include improvements to the homescreen, an upgraded camera app, the ability to send photos and videos from one phone to another via Google Beam, and more. The SDK for Android 4.1 Jelly Bean is already available for developers through developer.android.com.

Google Nexus 7 Tablet

Following the OS upgrade, Google finally confirmed the rumors and unveiled its latest tablet offering - Nexus 7 - the 7-inch Google-branded tablet manufactured by Taiwanese-based firm Asus.

As far as specs are concerned, Nexus 7 will pack a 7-inch display (with 1280 x 800 pixels resolution) in "Scratch-resistant Corning glass", 1.2MP front-facing camera and built-in NFC, as well as Wi-Fi and Bluetooth capabilities.

The tablet will come powered by Nvidia's Tegra 3 chip, which has a quad-core processor, 12-core graphics chip, 1GB RAM and will come preinstalled with Android 4.1 Jelly Bean OS. The Nexus 7 weighs 340 grams, has a dimension of 198.5 x 120 x 10.5 mm and is loaded with 4325mAh battery.

Kicking a direct competition with Amazon Kindle Fire tablets, Nexus 7 is now available for pre-order in UK, US, Canada and Australia via Google Play Store in two variants 8GB and 16GB, costing $199.99 and $249.99 respectively. The device is set to ship in mid July.

In addition, Nexus 7 tablet is an attempt to heavily attract consumer media from the Google Play Store, as the tablet will support a full complement of media types, such as, video, magazines, music, books and more. Furthermore, Nexus 7 will also offer a custom Google Maps app. Other goodies include Chrome browser, a free copy of the latest Transformers movie and $25 credit in the Play Store.

Google Nexus Q

Google also unveiled its home streaming device on the first day of the conference - Nexus Q. This ball-shaped Android is already made available on Google Play Store and it will allow users to share media from the store with their home entertainment center. But the Nexus Q is not a standalone platform like Apple TV. It would require an Android smartphone or tablet connected to the same Wi-Fi network to access content offered on Google Play.

The Nexus Q will let the users collaborate with friends through their Android phone or tablet to put together music and video playlists. The Nexus Q ships in mid-July, and would cost $299 for a 16GB model.

Google+ Tablet App and Events

Google also introduced a new app for Google+ for both Android and iOS devices. The new app will let the users send invites to friends for events, share photos, etc. The new Google+ app is available from June 27 for Android phones and tablets; the iOS version is pending approval from Apple.

Google Glass

Google co-founder Sergey Brin broke up the Google+ announcement and demonstrated the company's nascent offering - Google's Project Glass - the company's futuristic head-mounted computer.

Google official informed that the device hardware will come with features like camera, speaker microphone, and it will also include a touchpad on the side for user interaction.

Further, it will stack a compass, gyroscope, accelerometers and multiple radios for a data connection (presumably 3G, 4G, and Wi-Fi). Any further details were not provided by Google. Although, it was informed that despite the fact that product is not available in the market till now, still the U.S.-based developers, who were attending Google I/O were allowed to preorder a prototype version of the device worth $1500, which will be shipped to them sometime early next year.
