What is a smart watch? In the late stage of the sports watch promotion, due to the rapid take-off of smart phones, smart watches have no intention to provide the same PIM function as PDAs and smart phones, but have been turned into proxy assistant accessories of smart phones. Similar to Bluetooth headsets, they are voice assistants of smart phones, while smart watches have become information and data assistants, providing more convenient and fast information display and operation. Therefore, smart accessories (smart accessories) are also available Android remote (remote control of Android smartphone) and other nicknames. The idea of positioning it as a proxy for mobile phones is that "the reason why pocket watches disappear is that it takes about 2-3 seconds to just watch the time and take out your pocket, but the watch takes less than 1 second, which is more convenient than pocket watches." After observation, now everyone takes out his smart phone and slides it out one day just to confirm the message. In this way, it takes about dozens of times a day, and these confirmations don't even need typing replies. If these dozens of confirmations are changed on the watch, there is no need to constantly pull out the machine and slide it to unlock it, because it's as time-consuming as a pocket watch. Therefore, after becoming the assistant and remote control of mobile phones, if you don't take your mobile phone out of the door, the watch is useless except for displaying the time. It is almost a piece of scrap iron like Bluetooth headsets without mobile phones.
The transformation of smart watches from "independent computers smaller than PDAs" to "remote control helpers for smart phones" seems to have been a more successful positioning, but this time CES 2014 can see that the positioning combined with smart bracelets is better. The smart Bracelet uses acceleration sensors (gyroscopes, magnetoresistive sensors, etc.) to sense the user's running speed, steps, etc., and even detect deep and shallow sleep, providing suggestions for exercise and sleep. When the bracelet is added to the display, it can display the time and information on the mobile phone. If there is no urgent information demand for mobile information, it is only similar to Bluetooth headsets, which are regarded as optional supplies (needed by express delivery personnel and drivers). If everyone can accept the sliding speed of information access, the market will be limited. However, the additional demand for the record supervision of exercise and sleep, and the emphasis on information prompts, rather than the remote control of the watch on the mobile phone, is equivalent to a little or almost no sacrifice to the end user, but it brings immediate and new application value (exercise and sleep assistance), rather than the efficacy value completely repeated with the mobile phone, which further increases the market success of the smart watch. After constantly adjusting the efficacy, application and positioning, And integrated with smart bracelets, I believe it can have a higher market acceptance than in the past.
