Smartwatch Introduction

A smartwatch, as the name implies, is a wearable device that integrates various smart hardware and systems into a small wearable device.

The biggest difference between a smartwatch and a regular electronic device is that it has many built-in systems inside that may be connected to external devices.

For example, the Apple iWatch is a wearable smart device that connects to the iPhone and Apple watch, while the Android Wear OS watch is a watch with smartphone functionality.

According to market research firm Gartner, the global wearable market will reach $45 billion by 2022.

Wearable technology has had a profound impact on human life, changing our lives from daily travel, work and sports. In the next 10 years, the wearable market has the potential to surpass the personal computer market.

 

1、Appearance

Although it looks cool, in actual use, we found that the appearance of this smartwatch is not different from ordinary Bluetooth headset.

But there is an interesting little detail.

When users do some regular operations on the watch, such as clicking and sliding, it will produce a slight vibration to the device to remind users.

And when you wear this smartwatch, these vibrations will be better presented to remind people to perform the operation.

As we know, this smartwatch features a removable strap.

If users need to change the strap, they just need to open the cover on the dial.

Of course, in order to facilitate the removal and replacement of the strap, most of the watches on the market now have a snap-on replaceable design; in addition, some of the watches also provide a strap selection interface for replacement.

This is a good continuation of the Apple Watch.

 

2、Application

Smartwatch applications are very promising, including many fields.

-Healthcare: Through wearable technology, smart watches can monitor users' blood pressure, heart rate and other physiological indicators, and monitor users' health status in a timely manner, which will help prevent diseases such as heart disease and diabetes.

-Fitness: the user's physical condition can be monitored while wearing a smartwatch, and the user's heart rate and step count can be monitored to measure whether the body has reached the exercise standard.

-Office equipment: Wearing wearable devices can monitor the user's sleep status, work stress status, etc. Through monitoring the physical condition, it can guide employees to make work arrangements and thus improve work efficiency.

-Leisure: Wearing wearable devices can also understand and track the user's heart rate and other physiological indicators in real time, so as to make adjustments to the user's health condition.

-Health monitoring: smart watches can monitor the user's sleep quality, exercise intensity and heart rate information at any time.

-Fitness exercise: wearing a smartwatch can record the exercise you do daily and can be compared.

Smartwatch application prospect: According to Gartner's forecast, smartwatch will grow at more than 10% in the next 5 years.

In addition to the huge market potential in healthcare, the business model aspect of wearable devices is also very imaginative. Many smartwatches currently have only one simple application: a notification function.

Since smart and wearable technologies are complementary, many companies are working to integrate this "all-in-one" approach into their smart hardware products.

 

3. Sensors

The core of a smartwatch is the sensor, which is a very important part of the overall wearable device.

Smartwatches use a large number of micro-electro-optical (MEMS) sensors inside, which can detect physical signals in the environment, such as vibration, temperature, pressure, etc., and these small changes will be monitored (such as heart rate).

Current mainstream smartwatches have more than 3-5 sensors built in; they include accelerometers, gyroscopes, barometers, geomagnetic sensing, etc.

Besides being widely used in wearable devices, they are also used to monitor the physical environment around us, such as temperature, pressure, etc.

And some other smartwatches have more types of sensors.

Apple Watch Series 3 includes: accelerometer, gyroscope, geomagnetic sensing and optical heart rate sensor.

These sensors are integrated in Apple's smartwatches, and users can monitor their physical condition from these devices.

Some smartwatches will also be equipped with pressure sensors that can assess the user's physical condition and give feedback.

In addition, it can also measure human stress levels and heart rate data, and even work with health experts to collect health-related data, such as sleep status and stress levels.

In addition, some smart watches are also equipped with a heart rate monitor (which can record the user's real-time heart rate) as an auxiliary function; they also have functions such as GPS system, music playback system and voice assistant.

 

4、Functions

Smartwatch is very powerful, but it can also be said that it is just a fashionable decoration, and its functions are not much different from other electronic devices.

The smart watch mainly includes the following aspects.

(1), pedometer: a smart device that can help people achieve healthy exercise.

(2) Weather forecast: It can provide accurate weather information and can automatically update the weather information according to the user's own area, thus making the user's travel more convenient and safer.

(3), time: you can set an alarm clock to remind you automatically, or connect with your phone to set an alarm to avoid disturbing others.

(4), Phone and SMS reminders: You can set reminders for specific phone numbers or SMS to avoid missing calls.

(5)、Payment: It can realize online payment function or connect with cell phone to realize cell phone recharge function.

(6), weather forecast: can be connected with weather software to automatically forecast local temperature, humidity and wind information.

(7), navigation: a destination can be set as a navigation point, allowing users to be more secure and reliable while in motion.

(8), Music playback or Bluetooth device charging: Bluetooth can realize music transfer to the watch; or transfer data from cell phone music directly through the watch; when running, you can use Bluetooth headphones to listen to your favorite rock music, etc.

 

5、Security analysis

One of the most important security features of the smartwatch is identity verification. When you are using the smartwatch, it will record all your identity information in the smartwatch, so as to ensure your information security.

When a smartwatch is connected to a phone, the user needs to enter a password to activate the device.

If there is no password, then the user cannot view any information in the smartwatch.

Users can connect their devices to the smartwatch via Bluetooth or they can use other devices to connect.

When before using Bluetooth connection, you need to check whether your phone has been updated to the latest version (Android 8.1 and above).

In addition, when the device is Bluetooth linked, the user also needs to enter the security password set on the phone to complete the connection process.

In addition to authentication and security features, the smartwatch can also detect if the user is in an abnormal state (e.g. sleeping) and alert the user in time.

In addition, the smartwatch can detect if the wearer is suffering from a disease or has other health problems (such as alcohol abuse, cardiovascular disease, chronic lung disease, etc.).
