More recently, novel application of these inbuilt sensors has enabled new and inventive uses for the smartphone in the area of health and wellness. For example, tri-axial accelerometers are useful in determining the spatial positioning of the smartphone and thus enabling the screen to re-orientate when the handset is rotated, and proximity sensors are used to switch off screen controls when the handset is held to the face during a phone call. Global smartphone penetration continues to rise rapidly due to their increasing value and utility, their ease of use and their increasing affordability.ĭue to the increasing miniaturisation of sensors and circuitry, smartphones have been able to leverage multiple inbuilt sensors to enhance user experience and provide other features. A smartphone is “a mobile phone that performs many of the functions of a computer, typically having a touchscreen interface, internet access, and an operating system capable of running downloaded apps”.
