An optical mouse is a computer mouse which uses a light source, typically a light-emitting diode (LED), and a light detector, such as an array of photodiodes, to detect movement relative to a surface. Variations of the optical mouse have largely replaced the older mechanical mouse design, which uses moving parts to sense motion.
A computer mouse (plural mice, also mouses) [nb 1] is a hand-held pointing device that detects two-dimensional motion relative to a surface. This motion is typically translated into the motion of the pointer (called a cursor) on a display, which allows a smooth control of the graphical user interface of a computer.
Latency, from a general point of view, is a time delay between the cause and the effect of some physical change in the system being observed. Lag, as it is known in gaming circles, refers to the latency between the input to a simulation and the visual or auditory response, often occurring because of network delay in online games.
This is the lag caused by the television or monitor (also called output lag). In addition to the latency imposed by the screen's pixel response time , any image processing (such as upscaling , motion smoothing , or edge smoothing ) takes time and therefore adds more input lag.
This lag time has been measured as high as 68 ms, [1] or the equivalent of 3-4 frames on a 60 Hz display. Display lag is not to be confused with pixel response time, which is the amount of time it takes for a pixel to change from one brightness value to another. Currently the majority of manufacturers quote the pixel response time, but neglect ...
We evaluated each controller on its functionality, design, and price, keeping a close eye on comfort, lag, and battery life. Core Xbox Controller.
In Fitts's words, "The average rate of information generated by a series of movements is the average information per movement divided by the time per movement." [1] Thus, = Today, IP is more commonly called throughput (TP). It is also common to include an adjustment for accuracy in the calculation.
The Fed cut its federal funds rate — the interest rate banks charge each other for short-term loans — by 0.25 percentage points, lowered the rate to a range of 4.25% to 4.5%, down from its ...
