Following the release of Qt for Tizen 1.0 Alpha 3, here is a video by Leon Anavi showing a Sensor application that demonstrates Qt’s support for sensors on Tizen smartphones. Available sensors include rotation, compass, accelerometer, gravity, proximity and light sensor, gyroscope, and magnetometer.
The APIs are identical to the Qt Quick APIs from Qt 5. This gives application developers exceptional level of portability across competing platforms such as Tizen, Android, BlackBerry 10, Ubuntu Phone, Sailfish OS, and more (iOS support is a work in progress).
Tizen developers can use the standard Qt Quick APIs to utilize sensors in their applications and games. The very same support is designed for many embedded devices including Tizen In-Vehicle Infotainment (IVI) products.
Support for Tizen has been added thanks to the flexible C++ sensor plugin API of Qt. As always in the case of Qt for Tizen, the same APIs are also supported by Tizen Emulator.
