Muhtasari	The User Experience Questionnaire (UEQ), developed by Laugwitz, Held, and Schrepp in 2008, is a practical instrument for assessing user experience of interactive products and systems. It measures six dimensions of user experience using semantic differential item pairs, balancing comprehensive coverage with brevity (26 items in the full version, 8 items in the short form UEQ-S). The UEQ has become widely adopted in software engineering, human-computer interaction, and usability research to evaluate websites, applications, and digital interfaces.	The Operator Performance Assessment Scale (OPAS), formalized by Wierwille and Eggemeier in 1993, is a structured rating method for assessing operator task performance on multiple dimensions (primary task accuracy, secondary task accuracy, task completion time, error rate, procedure adherence) in applied settings. OPAS bridges subjective workload perception (NASA-TLX, situational awareness) and objective behavioral metrics by capturing expert judgment of performance quality across multiple performance channels, enabling holistic evaluation of how well operators managed task demands.
