Vibration wake-up:
The smart bracelet has a built-in vibration component, which has a very unique function, that is, it wakes you up in sleep through vibration. Users can select the bracelet alarm clock in the settings to activate the vibration wake-up function, save it after setting the time, or set an important event reminder. This way of waking up or reminding is much healthier than an alarm clock, because research shows that being woken up by an alarm clock will make people feel flustered and depressed, and even affect people's memory, cognition and calculation speed.
Sleep tracking:
By pressing the metal cap before going to bed and after waking up, users can synchronize last night's sleep data, including the time and quality of sleep, to their mobile phones or tablets through smart bracelets. The smart bracelet clearly records four information for us: sleep time, deep sleep time, shallow sleep time and waking time. In addition to recording the sleep data of the day, there is also the sleep situation of this week, and the daily data generates a vivid color map.
Finally, you can share this week's sleep and these data on mainstream social platforms such as Weibo and WeChat, exchange sleep with friends, and make appropriate adjustments to your sleep according to the analysis results of the bracelet.
Motion monitoring
The most important function of the smart bracelet is motion monitoring, which can record the number of steps users walk every day in detail and accurately. Users can check the synchronization data of the smart bracelet through the mobile phone, mainly including the exercise time, free activity time, exercise distance, walking steps, energy consumption and so on. Users who work in the office sit still for a long time, and the smart bracelet can also detect and remind you to do some simple stretching exercises to exercise your bones and prevent muscle strain. Smart bracelets can also calculate calories burned according to age, gender, height and weight, as well as the intensity and time of activities.
Diet record
Reasonable diet control is also an important part of a healthy life. Although the smart bracelet does not have the ability to identify food, its powerful software can provide users with a very perfect food bank. Users can add food pictures or take photos to record the food they eat and choose the amount of food they eat. Then the software will show us how much energy food contains, and finally count the energy intake for us by time and catering type. Although this diet recording method can't calculate our real energy intake completely and accurately, it can provide a basic reference for our diet life.
Moreover, the smart bracelet not only pays attention to calories, but also compares the recorded food with the daily nutritional intake percentage suggested by nutritionists, so that users can better understand the health index of the food they eat and choose healthy and balanced recipes.
Function 5: Heart rate measurement. Another particularly interesting function of the smart bracelet is to measure the heart rate. Users can easily know their heart rate at any moment by wearing a smart bracelet on their wrists, and then use their heart rate during sleep or exercise to obtain a scientific sleep mode and exercise intensity. Although some users have reported that the accuracy of heart rate measurement method of bracelet is not high, with the development of science and technology, it is believed that relevant technical means will become more and more mature. In addition, users can share the heart rate measurement results with friends through their mobile phones, which is also very interesting.
fundamental function
It can be said that step counting and sleep quality tracking are the most basic functions of all smart bracelets at present. These two basic data are measured and recorded by smart sensors and flash memory chips in the bracelet. Other data, such as calorie consumption, walking distance, sleep quality, etc. , are based on these two data, through the software plus the user's height, weight, age and other values calculated. However, in the current scheme using motion sensors, there will be some errors in step counting.
Therefore, for the bracelet, the detection of motion by the built-in sensor and the algorithm of software are the prerequisites to improve the accuracy of the maximum step. Through the comparison of the above tests, it is not difficult to find that under the same test conditions, the bracelet with smaller cumulative step value has higher accuracy in step counting, and the recorded steps are closer to the real walking steps.
Of course, in addition to counting steps, sleep tracking is also a basic function of smart bracelets. However, for bracelets that need to manually turn on and off the sleep tracking function every day, Garmin Vivofit supports automatic and manual sleep tracking mode design, which is quite user-friendly. After all, we sometimes forget to turn sleep tracking on or off, and it is inevitable that the data will be destroyed.
Battery life: Frequent charging is still a nightmare. Short battery life is a common problem of most portable digital products at present. Due to the slow development of lithium battery technology, the current battery capacity is directly proportional to its volume, which leads to the frequent and irregular charging of many devices by consumers. However, for the smart bracelet that people need to wear continuously for 7×24 hours, when to charge it to avoid data interruption is a matter that every user should carefully calculate.
Synchronous mode
Smart bracelets still can't get rid of the dependence on terminal software and hardware. After all, after collecting a large amount of data, we need to synchronize the data with the corresponding APP of the bracelet to achieve permanent recording and analysis functions. Therefore, whether the synchronization method between the smart bracelet and the mobile phone or computer is convenient enough is also a major factor affecting the user experience.
Comfortable to wear
Compared with the function of smart bracelet, its material and design are equally important. A smart bracelet with comfortable material and ergonomic design will not feel uncomfortable after being worn for a long time. At present, most smart bracelets use medical-grade rubber, and some other bracelets also use a small amount of ABS engineering plastic or metal.
However, because everyone has different requirements for comfort, a few people will have allergic reactions to some metal materials. At present, many manufacturers use nonmetallic materials on bracelets to minimize the discomfort of people who are allergic to metals.
Reminder function
Only by adding the reminder function can we know the completion status or progress of the current goal more intuitively through the bracelet. For example, how many steps have been taken, how far away from the goal of the day, and so on. Whether using LED, screen or vibration, it is more convenient than taking out our mobile phone and viewing it on the APP. Although most smart bracelets have basic prompting functions, when we need to check the status, we need another hand to operate the bracelet to activate the display screen or LED lights on it.
network function
The smart bracelet also has a social network sharing function. For example, users can share sleep quality, diet, exercise and mood records through binding applications. For the elderly, it is also a patron saint. Through the built-in GPS connector, you can inform the relevant hospital or family members of your physical condition and location at any time.
A smart bracelet is a wearable smart device. Through this bracelet, users can record real-time data such as exercise, sleep and diet in daily life, and synchronize these data to iOS or Android devices to play a role in guiding healthy life through data.
Extended data:
Smart bracelet function:
Low energy consumption "love to share".
The smart bracelet has a built-in low-power Bluetooth 4.0 module, which can be connected to mobile phones, tablets and PC clients, and can set height, weight, stride length and other information anytime and anywhere and upload sports data. In addition, the smart bracelet also has a social network sharing function. For example, users can share sleep quality, diet, exercise and mood records by binding Weibo and other social networks.
Whenever the fatigue reminder time comes, the smart bracelet will remind you to have a rest in the form of an alarm clock, which is suitable for high-pressure office people and has a very humanized design.
In terms of service time, due to the built-in lithium polymer battery, the battery life of the smart bracelet can reach 10 days, and the battery life is still very strong.
As a new high-tech wearable smart device, the price of smart bracelet is generally high, generally around 600 yuan 1200 yuan.
The medical health bracelet can measure pulse, heart rate, skin temperature and other environmental information, such as illumination and environmental noise level. Through the health bracelet, even if the patient is not in the hospital, the doctor can track his health. However, Google bracelet will not be put into the market as an ordinary consumer electronic product, but can be provided to patients as a professional medical device or used in clinical trials.
Although there are many smart bracelets on the market at present, some of them are related to the health field, but the health module functions of bracelets are mostly to monitor sleep and exercise reminders. And there are few bracelets that help users treat their bodies. Therefore, this medical-grade health bracelet is not only a big project with long-term prospects in Google Labs, but also an important development direction of smart bracelets in the future.
