Perception threshold

感知阈值，用户能可靠感知到某种刺激（如延迟）存在的最小量值，是推导低延迟系统设计准则的关键参数。

English Definition

"The minimum magnitude of a stimulus (e.g., latency) at which users can reliably detect its presence; a key parameter for deriving low-latency design guidelines."

用法说明 · 针对中文母语者

在 HCI 设计中常用于回答「多少延迟是可接受的」。注意它和 JND 紧密相关但不等同：JND 是方法，perception threshold 是结果。

"To derive design guidelines for low-latency systems, it is essential to know how much latency can be perceived, from which point it starts to influence users, and what the maximum tolerable amount is."

"However, when dragging a virtual object over a touch-sensitive surface, delays as low as 2 ms can be perceived due to the spatial offset between finger and object."
