During the Q&A (question and answer) session of Apple's recent annual shareholder meeting, when someone asked about the significance of Apple's manufacturing plant in the United States, CEO Tim Cook made it clear that the company's investment in the sapphire processing plant was for a "secret project", and now Don't reveal too much. A series of previous rumors have said that Apple will use sapphire material on the new generation iPhone, aiming to further improve the surface scratch resistance of the iPhone, but after Cook said that this is a secret project that should not be discussed, he also said that in the United States of other Apple suppliers already make glass for the iPhone. An Apple spokesman declined to comment. Apple's iPhone products have been the focus of media attention over the years, with all kinds of speculation and rumors leading up to the release of each iPhone generation, some of which leaked from the supply chain. Apple's new product launch conference has also been jokingly called the "rumor verification conference". Therefore, when asked such a question on such an occasion, Tim Cook, the CEO, can't make some special hints anyway. For the iPhone, the use of sapphire material for the screen glass is also a very special change, and it is not an exaggeration to call it a "secret project". In fact, in this year's Samsung Galaxy S5, we also saw that it is too difficult to have a big "innovation" after the smartphone update iteration reaches a certain height. Samsung doesn't know how to use its talents after pulling up the hardware data and increasing the screen size. Cook's "secret project" may be Apple-style innovation.
2.The new gesture recognition technology can be controlled from a distance
You can mute a smartphone playing a song in your pocket with a flick of your finger in the air, or pause the sound of an audio magazine with a gesture. A research team at the University of Washington has built a low-cost gesture recognition system that runs without batteries, allowing users to control electronic devices hidden from sight with only simple hand movements. Its prototype is called "AllSee". This gesture-controlled electronic device technology could soon become the touchscreen sensing technology that replaces power-hungry smartphones and tablets. The technology will be announced at a panel discussion at the Network Systems Design and Implementation Conference in Seattle, April 2-4. "This is the first gesture recognition system that is less than a dollar to implement and does not require battery power, using a TV signal as both a power source and a source for recognizing gestures," said Shyam, assistant professor of computer science and engineering at the University of Washington. ." Researchers have built a small sensor that can be placed on electronic devices such as smartphones. The sensor uses an ultra-low-power receiver to extract and classify gesture information from wireless transmissions around us. When a person gestures with their hands, the amplitude of the wireless signal in the air changes, allowing AllSee sensors to identify this unique amplitude change caused by a particular gesture. The research team tested AllSee's functionality, such as push, pull, come, zoom in and zoom out, using eight different gestures on smartphones and battery-free sensors, Physicist Organization Network reported on February 27. The prototype can correctly recognize more than 90 percent of gestures, while performing manipulations of devices more than 2 feet away. The researchers also designed a wake-up gesture so that the system doesn't confuse unintentional movements for actual gestures. For the user, it's a seamless interactive experience. The gesture recognition can be installed on some mobile devices, including Samsung Galaxy S4 smartphones. But users have to manually enable the feature before being able to see the device's gesture technology at work. The technology can also be attached to home electronics, interacting with them with gestures, and connecting them to the Internet to play a role in the "Internet of Things" world. "AllSee goes beyond mobile devices to enable IoT devices to interact with each other," said Bryce Kellogg, a doctoral student in UW's electrical engineering department.
