Step detection using accelerometer sensor on mobile phoneHoang Minh ThangVo Quang VietDeok-Jai ChoiKorea Multimedia SocietyProceedings of the Korea Multimedia Society Conference
MEMS sensors are being used in latest mobile phones and gaming joysticks as step counters, user interface control, and also for switching between different modes. Used in mobile cameras as a tilt sensor so as to tag the orientation of photos taken. To provide stability of images in camcorders...
Capacitive accelerometers/capacitive accelerometers are a type of acceleration sensor that is widely used. In some industries, such as airbags, mobile phones, and mobile devices, there is no equivalent. Microelectromechanical systems (MEMS) are used in capacitive accelerometers/capacitive accelerometers....
There are several different types of accelerometers, each with its own working principle and advantages: Piezoelectric Accelerometers A piezoelectric accelerometer is a type of accelerometer that works by sending an electrical signal from the sensor when it experiences a sudden acceleration. The construct...
over a sliding window (w) of samples. The window slides by one sample for each computation. If the standard de- viation in a window exceeds a threshold (a), we detect movement. When the standard deviation is within the threshold for n successive sliding windows, we report ...
HP Mobile Data Protection Sensorcontinues to be in the same state - and the driver's version is still the same, 5.2.1.1: 3) Meanwhile, somehow I haveuninstalled HP 3D DriveGuard: At this point, I have no idea how to make the drivers compatible...

Human activity Recognition (HAR) using smartphone sensors suffers from two major problems: sensor orientation and placement. Sensor orientation and sensor placement problems refer to the variation in sensor signal for a particular activity due to sensors’ altering orientation and placement. Extracting ori...
While this model is not exactly how a MEMS sensor is constructed it is often useful in solving accelerometer related problems. There are actually similar sensors that have metallic balls inside, they are called tilt switches, however they are more primitive and usually they can only tell if the...
Move the sensor orientation and see the values changing accordingly.Sensor CalibrationIdeally, when the sensor is static, the gyroscope values should be zero on all axis, which doesn’t happen in our case. When the sensor is static, these are the gyroscope values we get:...
