Creating Applications with Sensors

A sensor is a device that detects or senses various signals or stimuli, such as acceleration, distance, orientation, and magnetic field strength, and transmits the resulting measurement. If you want to create applications that offer sensor features to the user, Tizen provides various options for you.

In a smart device application UI, sensors are useful in monitoring user gestures and motions.

When creating a sensor application, you can implement the following features:

• Accelerator sensor usage

  The accelerator sensor is used to measure changes in force resulting from fall, tilt, positioning, shock, and vibration. Smart devices rotate their display between portrait and landscape mode depending on how the user tilts the phone.

  • To avoid annoyance, you can determine whether the accelerator sensor is supported on the device before displaying the application features to the user.
  • You can request accelerator sensor events to be delivered to the application, where you can process and display them.
  • You can save the maximum acceleration value of the device during testing.

• Proximity sensor usage

  The proximity sensor measures the distance of an object from the front of the phone. It is commonly used on smart devices to detect (and skip) accidental touchscreen taps when held to the ear during a call.

  • To avoid annoyance, you can determine whether the proximity sensor is supported on the device before displaying the application features to the user.
  • You can request proximity sensor events to be delivered to the application, where you can process and display them.
