Current location-tracking technologies can be used to pinpoint users of mobile devices in several ways. First, service providers have access to network-based and handset-based technologies that can locate a phone for emergency purposes. Second, historical location can frequently be discerned from service provider records.
An infrared proximity sensor Optical proximity sensor in a 2016 Samsung smartphone.A proximity sensor is a standard feature of most smartphones, disabling the touchscreen when positioned near an ear during phone calls; more recent (late 2019-early 2020) smartphones with OLED displays may have the sensor mounted under the display.
Moving object detection is to recognize the physical movement of an object in a given place or region. [2] By acting segmentation among moving objects and stationary area or region, [3] the moving objects' motion can be tracked and thus analyzed later. To achieve this, consider a video is a structure built upon single frames, moving object ...

A motion detector attached to an outdoor, automatic light. A motion detector is an electrical device that utilizes a sensor to detect nearby motion (motion detection).Such a device is often integrated as a component of a system that automatically performs a task or alerts a user of motion in an area.
The paper explores early applications of Wi-Fi Sensing, including motion detection, gesture recognition, and biometric measurement. Moreover, it identifies potential business opportunities within the home security, health care, enterprise, and building automation/management markets. [ 13 ]
This is a list of mobile apps developed by Google for its Android operating system. All of these apps are available for free from the Google Play Store, although some may be incompatible with certain devices (even though they may still function from an APK file) and some apps are only available on Pixel and/or Nexus devices.
For example, a device with an accelerometer can detect rotation from vertical to horizontal state in a fixed location. As a result, accelerometers are primarily used for simple motion sensing applications in consumer devices such as changing the screen of a mobile device from portrait to landscape orientation.
