The app automatically logs every trip a rider takes (it works by using the phone's accelerometer,
gyroscope, and an algorithm to sense that a user is biking) and thus gathers a lot of short - trip
data that was previously very difficult to collect and study.
WiFi (802.11 b / g / n) is your only option for
data connectivity, though there's naturally Bluetooth and NFC, not to mention GPS, an accelerometer, a digital compass and a
gyroscope, too.
There's the M8 motion coprocessor, which analyzes movement
data from the iPad's compass,
gyroscope, accelerometer and now a barometer.
There is an embedded M10 motion coprocessor in the A10 Fusion chip that captures motion - based
data from the compass, accelerometer, and
gyroscope to power Apple's health and fitness capabilities without significant power drain.
There's also an embedded M11 Motion coprocessor that captures motion - based
data from the compass, accelerometer, and
gyroscope to power fitness capabilities, augmented reality experiences, and more, without significant power drain.
Developers can user three inputs to trigger their augmented reality effects: Face Tracker (but not identity or facial recognition), Sensor
data, such as the
gyroscope and location, and Scripting APIs to pull in
data from other apps and respond to user inputs in real time.
The motion coprocessor, first introduced with the iPhone 5s, is the chip that captures motion - based
data from the compass, accelerometer, and
gyroscope to power Apple's health and fitness capabilities without significant power drain.
The API uses low - power signals from a wide range of sensors to determine what the user is doing, relying on things like Bluetooth, Wi - Fi,
gyroscope, accelerometer, and location
data from cell towers and GPS.
The author, an engineering manager at Facebook named Ben Chen, wrote that it was not merely possible to detect that two smartphones were in the same place at the same time, but that by comparing the accelerometer and
