Keystroke logging. Keystroke logging, often referred to as keylogging or keyboard capturing, is the action of recording (logging) the keys struck on a keyboard, [1] [2] typically covertly, so that a person using the keyboard is unaware that their actions are being monitored. Data can then be retrieved by the person operating the logging program.
A psychomotor vigilance task ( PVT) is a sustained- attention, reaction-timed task that measures the consistency with which subjects respond to a visual stimulus. Research indicates increased sleep debt or sleep deficit correlates with deteriorated alertness, slower problem solving, declined psychomotor skills, and increased rate of false ...
Keystroke-level model. In human–computer interaction, the keystroke-level model ( KLM) predicts how long it will take an expert user to accomplish a routine task without errors using an interactive computer system. [1] It was proposed by Stuart K. Card, Thomas P. Moran and Allen Newell in 1980 in the Communications of the ACM and published in ...
In software quality assurance, performance testing is in general a testing practice performed to determine how a system performs in terms of responsiveness and stability under a particular workload. [1] It can also serve to investigate, measure, validate or verify other quality attributes of the system, such as scalability, reliability and ...
To generate software interrupts for x86 CPUs, the INT assembly language instruction is available. The syntax is INT X, where X is the offset number (in hexadecimal format) to the interrupt vector table. Signal. To generate software interrupts in Unix-like operating systems, the kill(pid,signum) system call will send a signal to another process.
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 input lag are cumulative.
Application performance management. In the fields of information technology and systems management, application performance management ( APM) is the monitoring and management of the performance and availability of software applications. APM strives to detect and diagnose complex application performance problems to maintain an expected level of ...
Software testing. Software testing is the act of checking whether software satisfies expectations. Software testing can provide objective, independent information about the quality of software and the risk of its failure to a user or sponsor. [1] Software testing can determine the correctness of software for specific scenarios, but cannot ...
