Sensors in Consumer Electronics That Improve Security and Enhance Overall Interactive Experience

Consumer electronics are electronic equipment used in day-to-day life, such as flat screen TVs, smart phones, personal computers, laptops, and others. Sensors play a crucial role in efficient operation of these devices. Increasing demand of customers for superior quality, slim design, high energy efficiency, and other features have enforced manufacturers to incorporate sensors in consumer electronic devices. Various sensors, such as temperature sensor, speed sensor, electronic sensors, and others have been installed inside laptops, smartphones, game consoles, and other devices to provide enriching experience and convenience to users.

Various sensors in smartphones:
There are various sensors used in smartphones that provide ease-of-use and security to users. The most basic sensor used in smartphone is accelerometer, which determines the orientation of device among three axes and rotates screen in portrait or landscape mode. Gyroscope also provides information about orientation, but with more precision than accelerometer. Few high-end devices have barometer, a sensor that measures atmospheric pressure and determines the distance above sea level, which in turn, results in enhanced GPS accuracy. A light sensor measures the brightness of ambient light and adjusts the brightness of display. A proximity sensor, which is placed at the earpiece of a phone, sends information to system that user is attending a call and display screen is turned off by system to save energy.


Apple’s technology and acquisition of patents:
Touch ID on iPhone and iPad enables users to unlock devices with their fingerprints. A user places finger on Home Button and a sensor residing underneath that button determines whether fingerprint matches with stored data. Home Button is made up of sapphire crystal that protects sensor and acts as a lens. Sensor used in Touch ID scans the details of fingerprint with precision and creates a mathematical representation. Then, it compares this representation with stored data to identify the match and unlock the device. In this way, sensors can be used in consumer electronics for security purposes.
Apple has acquired 26 out of 31 original patents of Privaris, a biometric technology firm. These patents are related to fingerprint and touchscreen technology. The acquisition of patents aims to improve Touch ID on iPhone and iPad. Apple is planning to eliminate physical Home Button and introduce a virtual Home Button by creating a multi-touch display with the help of integrated fingerprint technology. As per the reports from CNN, one of the patents acquired from Privaris enable users to use fingerprint technology and touchscreen at the same time. A fingerprint scanner residing beneath the screen can scan the finger through phone’s display. In this way, Apple will be able to create an iPhone with an edge-to-edge screen. Furthermore, Apple uses biometric sensors for authentication to authorize credit card payments using its Apple Pay service.
