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.
For example, suppose a process commands that a computer card's voltage output be set high-low-high-low and so on at a rate of 1000 Hz. The operating system schedules the process for each transition (high-low or low-high) based on a hardware clock such as the High Precision Event Timer. The latency is the delay between the events generated by ...
Optimizing the process that delivers the output by eliminating wasteful, unproductive output from the algorithm or method by which the result is produced. A decent process management system, giving the highest priority to operations that would otherwise interrupt the user's work flow, such as typing, onscreen buttons, or moving the mouse pointer.
A computer mouse with the most common features: two buttons (left and right) and a scroll wheel (which can also function as a button when pressed inwards) A typical wireless computer mouse. A computer mouse (plural mice, also mouses) [nb 1] is a hand-held pointing device that detects two-dimensional motion relative to a surface
Input lag or input latency is the amount of time that passes between sending an electrical signal and the occurrence of a corresponding action. In video games the term is often used to describe any latency between input and the game engine , monitor , or any other part of the signal chain reacting to that input, though all contributions of ...
The SLE mode is mainly aimed at low-power, low-latency, and high-reliability application scenarios, such as wireless headsets, mice, car keys, etc. It reportedly offers a data transmission rate of up to 12 Mbit/s , or six times that of Bluetooth, and supports bidirectional latency of 250 microseconds , simultaneous access by 256 users, and a ...
The bus bandwidth therefore only has an effect on the number of channels that can be sent at a time, not the speed or latency of the transmission. Low speed (LS) rate of 1.5 Mbit/s is defined by USB 1.0. It is very similar to full-bandwidth operation except each bit takes 8 times as long to transmit.
[citation needed] The lower one's ping is, the lower the latency is and the less lag the player will experience. High ping and low ping are commonly used terms in online gaming, where high ping refers to a ping that causes a severe amount of lag; while any level of ping may cause lag, severe lag is usually indicated by a ping of over 100 ms.
