Apple’s iPhone 5s offers more sensors than previous models, even those which we assume a forward-looking character “could”.
addition to the already existing sensors such as proximity, temperature, ambient light sensor and gyroscope, as well as components such as GPS, the iPhone 5s includes a fingerprint and a new motion sensor, or coprocessor called M7.
The fingerprint sensor called “Touch ID” could be one of the selling points of the iPhone 5s. The device is housed in the home button and has a resolution of 500 PPI, which scan the finger of the user in the superficial layers of the skin. The technology comes from the company “AuthenTec”, the Apple acquired in 2012. Since then, there was a persistent rumor about the scanners that are now a reality.
Initially the sensor should serve to safely unlock the iPhone 5s and authorize iTunes purchases. Further areas of applicability will then open up when using app developers Touch ID.
According to Apple’s Dan Riccio, the fingerprint is the best password. It has always there and there are no two fingerprints are exactly the same. Up to five can be saved in the iPhone. To use his own finger to unlock the iPhone 5s, the finger must be scanned several times from different angles to create a 3D model. So that the surface can be better recognized, Apple has used the home button scratch-resistant sapphire glass, which was first used for the camera lens of the iPhone fifth
Apple has acknowledged that touch ID was not without blemish. Moisture or other conductive deposits could lead to false scan results as scars. However, the user is free to use any finger.
The fingerprints are not stored on the sensor itself and not on iCloud, but on the A7 chip in the iPhone. The data is deleted if the device is rebooted or has not been used for more than 48 hours. In this case, enter the password again replaced the finger.
motion sensor M7 as a coprocessor
of Apple “M7″ baptized motion sensor is actually a co-processor that receives the data from accelerometer, gyroscope and compass and analyzed. While this data is loaded into its own processor and processed, the iPhone can work more efficiently.
M7 could be used by developers as apps for fitness but also navigation solutions. Also, the sensor was associated with improvements for the camera of the iPhone.
