To explain the elements of wearable technology in more detail, we will focus on the specifications of two popular devices, the Fitbit and the Apple Watch.
Avila and Bailey (2015) explain the basic elements of the Fitbit:
- The Surge – adds GPS tracking and an optical heart rate monitor.
- Ample memory to store enough information of second-by-second motion data.
- A monochrome LCD touch screen that allows a watch like feel.
- An app that can be run off the users device such as a phone or computer to view charts of data that has been wirelessly transmitted.
Avila and Bailey (2015) further explain the basic elements of the Apple Watch:
- Rotating digital crown – This allows the user to zoom in and out without blocking the screen with a pinching gesture.
- Taptic engine – this allows sensors to provide feedback to the user through vibrations and other notification methods.
- Heart rate sensor and accelerometer – provides detailed tracking in conjunction with the Wi-Fi and GPS system in the users smart phone.
Below, Apple (Introducing Apple Watch Series 4 2018) explain how much the watch has evolved from previous versions.
