Usability Evaluation
可用性评估课程系统介绍评估交互系统可用性的理论、指标与方法。课程涵盖专家评估法（启发式评估、认知走查）、用户测试法（实验室测试、远程测试、眼神追踪）、主观量表（SUS、NASA-TLX）与数据分析技术。学生将学习根据评估目标与资源约束选择合适方法，科学度量效率、有效性、满意度等可用性维度，并提出可执行的改进建议。
Usability Evaluation systematically introduces theories, metrics, and methods for assessing system usability. Topics include expert evaluation methods such as heuristic evaluation and cognitive walkthrough, user testing including lab, remote, and eye-tracking studies, subjective scales such as SUS and NASA-TLX, and data analysis techniques. Students learn to choose appropriate methods and measure usability dimensions scientifically.
学生需选定一款真实产品，制定可用性测试方案，招募6至8位目标用户完成3个核心任务的实验室测试，记录任务完成率、时间、出错率与主观满意度，并辅以启发式评估交叉验证，最终输出含问题清单、严重度评级与改进方案的可用性评估报告。
Students select a real product, design a usability test plan, recruit 6 to 8 target users for lab-based testing on 3 core tasks, record task completion rate, time, error rate, and subjective satisfaction, cross-validate with heuristic evaluation, and produce a usability report with problem lists, severity ratings, and improvement recommendations.
