Motion capture in the context of "Military science"

In computing, a motion controller is a type of input device that uses accelerometers, gyroscopes, cameras, or other sensors to track motion.

Motion controllers see use as game controllers, for virtual reality and other simulation purposes, and as pointing devices for smart TVs and Personal computers.

Computer animation is a digital successor to stop motion and traditional animation. Instead of a physical model or illustration, a digital equivalent is manipulated frame-by-frame. Also, computer-generated animations allow a single graphic artist to produce such content without using actors, expensive set pieces, or props. To create the illusion of movement, an image is displayed on the computer monitor and repeatedly replaced by a new similar image but advanced slightly in time (usually at a rate of 24, 25, or 30 frames/second). This technique is identical to how the illusion of movement is achieved with television and motion pictures.

Live-action animation is a film genre that combines live-action filmmaking with animation.Projects that are both live-action and computer animation tend to have fictional characters or figures represented and characterized by cast members through motion capture and then animated and modeled by animators. Films that are live-action and traditional animation use hand-drawn, computer-generated imagery (CGI), or stop-motion animation.

Frame rate, most commonly expressed in frame/s, frames per second or FPS, is typically the frequency (rate) at which consecutive images (frames) are captured or displayed. This definition applies to film and video cameras, computer animation, and motion capture systems. In these contexts, frame rate may be used interchangeably with frame frequency and refresh rate, which are expressed in hertz (Hz). Additionally, in the context of computer graphics performance, FPS is the rate at which a system, particularly a GPU, is able to generate frames, and refresh rate is the frequency at which a display shows completed frames. In electronic camera specifications frame rate refers to the maximum possible rate frames could be captured, but in practice, other settings (such as exposure time) may reduce the actual frequency to a lower number than the frame rate.

A pianist (US: /piːˈænɪst/ pee-AN-ist, also /ˈpiːənɪst/ PEE-ə-nist) is a musician who plays the piano. A pianist's repertoire may include music from a diverse variety of styles, such as traditional classical music, jazz, blues, and popular music, including rock and roll. Most pianists can, to an extent, easily play other keyboard instruments such as the synthesizer, harpsichord, celesta, and the organ.
