It's that time of the year when the tech world - developers and tech geeks alike - congregates at the Shoreline Amphitheatre in Mountain View, California. This year, too, the countdown has begun to the tech giant's 3-day annual fest that kicks off on Tuesday, and concludes on Thursday. Google I/O which stands for ‘innovation in the open’ brings together developers from around the globe for talks, hands-on learning with Google experts, and a first look at its latest developer products.There will be announcements about the future of Android and Google's AI efforts. But, there will also be news on everything from its new wearable platform, Wear OS, and Google Assistant to Android TV, Google Home, Google Play, and Search.This is the time of the year when Google pulls out all the stops to showcase how its software is smarter and more forward-looking than the products from its rivals Amazon Facebook , and Microsoft You can watch Google CEO Sundar Pichai deliver his keynote on the Google Developers YouTube channel https://www.youtube.com/user/GoogleDevelopers You can also watch the live streaming on:Here's a quick run-down of what to expect:This will be one of the biggest announcements from Google. Comparatively different from Android Oreo which debuted last year, Google's latest approach to mobile software is more visual and focused on interface design improvements. If rumours are to be believed, Android P might incorporate some of Apple's iPhone's features.It is expected that Google is probably going to move to a more minimalist and clean interface with Android P.Android TV has been around for a few years, and last year an Android O version was unveiled. A new, 4K Chromecast-like Android TV dongle may be released which would include the full TV interface and possibly a remote.While Android Auto has been around for a few years, it's most-recently added wireless support for Pixel and Nexus devices made news when launched last month. Back in January, Google announced that its Assistant software would soon power voice functions for Android Auto, so it's likely I/O will mark the launch of that feature.Google Assistant remains Google's largest competitive push against Amazon's Alexa and, Apple's Siri and Microsoft's Cortana. And while Assistant does live on iOS and Android devices as an app and voice interface, it's most readily useful as the OS layer for any number of smart home devices.This I/O is where we're expecting Google to finally catch up by showing off a smart speaker with a built-in screen. There can be several form factors to this: round, rectangular, large & small but the idea of having a screen remains the same. It just adds another dimension to your smart speaker interaction, showing you more info that isn't necessarily spoken aloud by the assistant.
