A smart watch that can call and monitor health, how far away we are

In the computable wrist strap, one of the most anticipated is the smart watch, but I advise you to give up the idea, at least for now it is impossible. I'm a dreamer, and I want everything. I want a watch, I can receive notification information, I can make a phone call, I can track my heartbeat and fitness activities, and more importantly, this watch doesn't need to be recharged every day. Sadly, the watch has not yet appeared. From any point of view, smart watches are unlikely to be sold on the shelves anytime soon. Although some of the equipment was exhibited at the Consumer Electronics exhibition held earlier this month, this only gives us a clearer vision of how the latest wearable computing and smart watch markets are changing. In short, you can use smart "watch", but it must be with a smartphone (or other devices) with the use, so as to make this "watch" has a strong processing power and wireless function. This means that in the foreseeable future, smart watches are actually a niche device, for example, it only supports reminders/communication functions or provides some health-related fitness tracking services. It also means that in a short period of time, you may not be able to put a smartphone on the wrist, but also to say that Samsung's ill-fated Gaxlaxy gear is not really a smart watch. Since last year, companies such as Apple, Google and Samsung have all applied for smart-watch patents, and the concept of smart watches is starting to surface, and there is a presumption that all this seems to indicate that smart watches have broken through. But it turns out that if you look at smart watches as an independent technology, it's more difficult than you think. The PC market is shrinking incredibly like Apple, Google, Intel, Microsoft, and so on, and so on, the computer engineers in these giant companies are looking at mobile phones a few years ago, and the challenges they face seem to be obvious, and to be sure, the challenge is not simple: to provide a mobile phone, It needs to have the same computing power as a PC computer, and the handheld device is not large enough, and requires excellent wireless connectivity and long battery life. By the January 2007, the advent of the iphone had been largely at the heart of it, and it was only missed from a basic level. From this point of view, we seem to have lagged behind in the game. Smartphones today are more powerful than PC PCs a few years ago. Smartphones and tablets will carry 64-bit infrastructure in 2014, and some will rise to 4GB of memory. No wonder even the netbook-like gadgets are facing elimination. But the price of the watch is completely different, it is very clear, so far, no one is going to go back to the smartphone that year's script. The reason is that the difficulty is really too big, the author here summed up three words to illustrate this, they are: heat, battery life, and control. Do you think the device will become hot when your smartphone is running at a high load, such as streaming video or playing games? This is because the phone processor in the high-speed processing of electronic activity generated by excess heat. If a smart phone has the ability to handle computing like a smartphone, it means that it needs a processor that can handle multitasking, and, importantly, it must be cooler than a smartphone because you need to wear your watch on your wrist, and if it gets too hot, soften the strap, On the other hand, it may even cause a skin burn to the user. This is one of the biggest reasons why smart watches do not power today, at least in terms of smart watch standards. For example, it is said that the chip on the Toq smart watch launched by Qualcomm is not a variant of their own 骁丽 Dragon processor, which is actually currently loaded on most smartphones in the market. So what kind of chips do their Toq smart watches carry? The answer is the arm cortex-m3 chip, a microcontroller that is often used in low-level applications, factories, or cars. Compared with Hairon chip, the integration function of CORTEX-M3 chip is not strong, especially the lack of wireless function and GPS positioning function. But it saves the processing power, thus reducing the heat output, and the CORTEX-M3 chip is very small in size and fit to be loaded into the watch. But if the user wants a smart watch to behave like a truly connected computer, its ability to handle complex tasks is still quite lacking. Of course, the CORTEX-M3 chip can play the role of a traffic policeman, which can plan data from other processors, including pedometer accelerators and external GPS receivers. (The M7 motion coprocessor on the IPhone 5S is designed based on the CORTEX-M3 chip.) But those features have not yet been integrated into the CORTEX-M3 chip, which is one of the biggest problems, because users tend to want to be able to improve their original computing power in one watch as much as possible. Some chipmakers are likely to accept the challenge, but the bad thing is that unless they can confirm that their products have a viable market, they will integrate all the functionality into a single chip, and these manufacturers are very influential in the industry, such as Apple, perhaps Samsung. In 2013, of course, some of the top smart watch makers chose the 骁丽 Dragon-level processor. But they did it by pressing the chip on the smartphone to the smart watch. Smart watches still play the role of smartphone penniless cousins unless manufacturers can solve the problems of heat and power consumption. In fact, you'll find a clear distinction in today's wearable market, with a wrist strap that supports health features and a smart watch with reminders. The problem is one of the big reasons for the present. (WhenHowever, cost is another factor, if you want your watch to do everything, then the price is naturally not low. So why not let smart watches do simple things and then drop the price down to the consumer's acceptable range? Battery life battery life for any watch, or other smart devices, is a very important thing. The user experience can be very bad if the battery has to be constantly replaced or recharged repeatedly. Unfortunately, the two most important elements of smart watches (one is the processor mentioned above, one is the screen) require strong power support. Samsung's Galaxy Gear smart watch has a Super AMOLED display like a smartphone, with a 800MHz power processor. This is definitely a challenge for battery life, which leads to a very bad battery lifetime for gear watches. Samsung said the watch lasted only 25 hours, and some technology commentators said the watch had to be recharged for a full two days to have a good length of use. Blame it on the screen. Today, only a handful of smart watches on the market can support a full day of use, most of which can only last a few hours. This problem is largely related to the screen technology they choose, sometimes with very limited screen choices. For example, Pebble smart watches, whose screens use the "Trans-LCD display (Transflective LCD)" provided by sharp, are monochrome and slow to handle images, but with low power. Qualcomm's Toq smart watches use their own MEMS technology screens, which are called Mirasol. E-ink is the maker of Amazon's Kindle E-book screen, and their screens are more common. If the smart watch only needs to receive some notification information, the display screen can do a little bit more simple. Smart watch if there is a good screen, then it is to improve battery life, generally allow the watch to use the time to maintain 4-10 days. But now some manufacturers are starting to work on this, for example, according to an industry source, HTC has been licensed by Qualcomm's design and hardware development kit. Control so far, smart watches are inherently difficult to control. Obviously, the keyboard, and other virtual operations are difficult to control, plus the size of the screen, so that touch-control has become useless. These problems make today's smart watch more using side-button control, these interesting keys to people think of the early digital watch, users can also use the numeric keypad to send some text messages. There will be some solutions, such as voice commands and speech recognition to solve the problem, and there are already Apple's Siri and Google Now products in the market. There are also techniques based on gesture computing, such as Google Inc.The X8 computing system has been mounted on the Moto X phone. In addition, augmented reality can be applied if Google launches smart watches. Is it jewelry or a computer? In today's era, the market for PCs, laptops, and netbooks is shrinking, replaced by phones and tablets, and it's unbelievable what happened. And now, our interconnected world has come up against an urgent need for powerful mobile computing. This technique, at least for now, is wearable computing. Before smartphones, mobile phones are ubiquitous, and it has to be said that everyone needs a cell phone and they need a phone to do more. On the contrary, not everyone needs a watch, especially now the phone has the timing function. (Even some people think they need wearable devices like Google glasses, and they want wearable devices to hang on their faces.) Maybe the watch always plays the role of jewellery, not something that everyone needs to wear. Even if the heat, battery life, and processor problems are solved, many people may not be able to wear smart watches on their hands. Smart watches will not come out anytime soon unless there is a killer app that makes it impossible to refuse.
