Google released the new Andriod 12 after two years, AI is the biggest protagonist!

Last year, the Google I/O Developer Conference, which released pigeons due to the epidemic, returned in an online live broadcast at 1 am Beijing time today.

The live broadcast of more than two hours can be said to be full of content and highlights of the whole story. The theme of this conference is "Building a more useful Google for everyone", and its purpose is to provide every user with help at critical moments. After reading the conference, Diandian really realized: What is technology to change lives.

This conference is no longer simply a show of technology, but a display of the future world after integrating smart technology into life.

Android 12 is no longer lacking

Google showed everyone a new design language tailored for Android12-Material You.

This design makes its appearance a lot higher. It can match the color combination according to the color you choose or a custom wallpaper, and choose a more beautiful and harmonious color combination for you, and become the Android 12 Theme color. Not only that, but Google also uses rounded corners on a large area for new icons and small components to make them look more sleek and smooth.

At the meeting, Google confirmed that this design will appear on the new Pixel products released this fall for the first time, which means that the official version of Andriod will not be released until the fall. At the same time, Google also said that in the future, "from network applications to hardware" will abide by this design language, which means that future wearable devices, smartphones, tablets, and Internet of Things projects will fit Material You's new color combination.

Android 12 not only puts great efforts on visual design, but also simplifies many interactive functions. Simpler animations will make users feel smoother.

After simplifying the system, Android 12 responds faster and has a higher energy efficiency ratio. Google said that the CPU time required for core system services has been reduced by up to 22%, and the system server's large-core CPU utilization rate has been reduced by as much as 15%, which will be very friendly to the battery life of the mobile phone.

, Google has further protected the privacy of users.

The first point is the brand new privacy board. On this panel, the user can see all his permission settings, as well as which data is being accessed, the frequency of access and the applications that have used it. Users can also cancel application permissions at will.

The second point is that when the app uses the microphone or camera, there will be a privacy indicator displayed in the upper right corner. The presentation is similar to that of iOS, and it is more intuitive than the presentation of Andriod 11. Its manifestation is a small colored dot.

The third point is to ensure privacy and security through technical design such as Android's private computer core. It can be understood that it is a privileged space in the operating system, which only retains the data for learning and use by the device locally, and will not be spied by the outside.

After talking about Android, Google said that it hopes to build a network with mobile phones as the core and capable of cooperating with computers, cars and other devices.

Finally, there is a small egg, Android 12 can also realize the function of digital car keys in the future. Google said that it is discussing cooperation with BMW, and digital car keys will be introduced to more brands of cars in the future.

Wear OS is back online

In wearable devices, Google can be said to be a veteran player, but due to various reasons, it has not become the representative of wearable devices in the eyes of the public.

At this conference, Google announced a major change. They will unite Samsung and Fitbit, which has been acquired by Google, to rebuild WearOS.

Samsung has been using its own Tizen OS on wearable devices in the past few years, but when Google relaunched Wear OS, Samsung decided to join forces with Google to integrate Wear OS and Tizen OS.

The battery life of the integrated Wear OS will be significantly improved, the loading time of the APP will be reduced and the animation will be smoother.

AI is the highlight

Based on powerful artificial intelligence algorithms, Google showed two AI-based models in the keynote speech-LaMDA and MUM.

Natural language platform-LaMDA. SundarPichai said: "We have completely changed the computer's ability to understand natural language."

If you talk to Pluto or a paper airplane, what will you get?

For this reason, Google has established a complete set of artificial intelligence dialogue model LaMDA. Through machine learning algorithms, it can not only select the most accurate answer trigger from the pre-configured response list, but also it can adjust the response result through active learning. .

In other words, LaMDA can achieve a more intelligent question-and-answer dialogue, and can provide suggestions and answers based on the context.

A new multi-task unified model-MUM.

The ability of MUM is 1000 times that of the existing BERT. It can process text, pictures, videos and other information at the same time, and finally obtain unified information with strong reference value.

At the press conference, Google demonstrated a use case of MUM. The user told MUM that he had successfully climbed Mount Adams and would like to climb Mount Fuji next year. What should I do to prepare?

MUM provides the most reasonable climbing route, time, and equipment requirements based on the photos, videos, route maps and other information provided by users, as well as the seasonal and geological differences between Mount Fuji and Mount Adams.

Google said that MUM will combine your query intent with a deep understanding of the world's information to solve the most complex searches. Like LaMDA, MUM is currently still in the development stage, and no clear time is given when Google can be used.

In addition, Google officially released the fourth generation of TPU at the conference.

According to reports, each device has 4096 TPU V4 chips, and one Pod can provide more than one Exoflops (floating point computing power of 10^18) AI computing power.

In addition, Google also revealed that it is developing a new tool that can easily delete all photos of a certain person from the photo library. For example, you want to forget the predecessor who frequently appears in the album.
