System Response Times (SRT)

系统响应时间：HCI 的基础概念，指用户操作与系统反应之间的时间间隔。经典的阈值包括 0.1 秒（瞬时感）、1 秒（思路连贯）、10 秒（注意力流失）。

English Definition

"A foundational HCI concept referring to the time interval between a user action and the system's corresponding response; the basis for classic latency thresholds (0.1s immediacy, 1s flow of thought, 10s loss of attention)."

用法说明 · 针对中文母语者

在论文中常缩写为 SRT，是 HCI 课程和文献的入门核心词。讨论 LLM 时代时，常被用来对照'确定性系统'与'概率性系统'的差异。

常见错误

·与一般的 response time 混用——SRT 在 HCI 中特指面向用户感知的研究范畴
