In 2019, Samsung released the Galaxy Watch, which had a 1.3-inch display and a starting price of $279, while Fitbit released the Versa, which had a 1.34-inch display and a starting price of $199. The smartwatch market has also seen significant advancements in recent years, with the introduction of new features like electrocardiogram (ECG) monitoring, which was first introduced by Apple in 2018, and blood oxygen level monitoring, which was introduced by Samsung in 2020. Furthermore, the use of voice assistants like Siri, Google Assistant, and Alexa has become more widespread in smartwatches, with 80% of smartwatches now supporting voice commands.
Smartwatches work by using a combination of sensors and software to track user activity, including GPS, accelerometers, and heart rate monitors, which can track up to 100 data points per second, as reported by a study by the Journal of Medical Engineering & Technology. For example, the Apple Watch uses a built-in GPS chip to track user location, while the Samsung Galaxy Watch uses a combination of GPS, GLONASS, and BeiDou to provide more accurate location tracking. The data collected by these sensors is then transmitted to the user's smartphone or cloud storage, where it can be analyzed and used to provide insights into user behavior, with 90% of smartwatch users tracking their daily activity levels, according to a survey by the National Sleep Foundation. The technical details of smartwatches also involve the use of machine learning algorithms, which can learn user patterns and provide personalized recommendations, such as the Apple Watch's "Fitness+" feature, which uses machine learning to provide personalized workout recommendations. Additionally, smartwatches use a variety of wireless communication protocols, including Bluetooth 5.0, Wi-Fi, and NFC, to connect to other devices and enable features like mobile payments, with 40% of smartwatch users using their devices to make payments, according to a report by Mastercard.
