In Chunithm, players use touch and motion-based sensor bars to input commands that correspond to the notes scrolling down from the top of the screen.Depending on the type of note, players may be required to tap, hold, or slide their fingers against the bottom sensor bar or wave their hands up and down in the air between the sensors located on either side of the machine.
Occupancy sensor types include: PIR sensors, which work on heat difference detection, measuring infrared radiation.Inside the device is a pyroelectric sensor which can detect the sudden presence of objects (such as humans) who radiate a temperature different from the temperature of the background, such as the room temperature of a wall.
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.
In air and missile defense (AMD), the Integrated Air-and-Missile Defense system (IAMD) is an United States Army Space and Missile Defense Command (USASMDC) research program to augment the aging surface-to-air missile defense systems and to provide the United States Army with a low-cost, but effective complement to kinetic energy solutions to take out air threats.
The MIM-104 Patriot is a mobile interceptor missile surface-to-air missile (SAM) system, the primary such system used by the United States Army and several allied states. It is manufactured by the U.S. defense contractor Raytheon and derives its name from the radar component of the weapon system.

However, initial size, power consumption and price had prevented their mass adoption in consumer electronics. While there are other kinds of motion detector technologies available commercially, there are four principle types of motion sensors which are important for motion processing in the consumer electronics market.
The most common sensor applications with a sampling rate of less than 1000 Hz are CCD or CMOS cameras. The sensor is partitioned into individual pixels whose exposure value can be read out sequentially. The position of the light spot can be computed with the methods of photogrammetry directly from the brightness distribution.
