Përmbledhja	Interface Usability Measure (IUM), exemplified by the System Usability Scale (SUS) developed by John Brooke in 1986 and extended by Lewis and others, is a rapid, single-scale or multi-item assessment of perceived interface usability. IUM captures how easy, intuitive, and satisfying users find an interactive system, ranging from 10-item SUS questionnaires to custom domain-specific usability measures. IUM is widely used in software development, web design, and human-factors research to quantify user perception of system ease-of-use and guide iterative interface improvement.	The Cognitive Load Scale (CLS), developed by Fred Paas in 1992 and refined by Paas and colleagues in subsequent years, is a brief, single-item or multi-item self-report instrument for assessing the cognitive load (mental effort) imposed by a learning or task environment. Originating in cognitive load theory research, the CLS has become a fundamental measurement tool in educational psychology, instructional design, and human factors, used to evaluate how instructional materials, interface designs, or training methods affect learner or operator mental burden.
