Latency variation

延迟波动:系统在多次交互中延迟值发生变化的现象,常由轮询率、任务调度和网络抖动引起,与恒定延迟有本质区别。

English Definition

"The fluctuation of system latency across multiple interactions, often arising from polling rates, scheduling, and network jitter; distinct from constant latency."

用法说明 · 针对中文母语者

在交互系统设计中应将延迟视为概率分布而非常量;研究上区分 'constant latency' 与 'varying latency' 的用户感知与适应策略。

常见错误

  • ·与 'jitter' 完全等同——jitter 通常特指网络层波动,latency variation 涵盖软硬件全链路
  • ·忽视小幅频繁波动的影响,相关研究相对稀缺

真实用例 · 3

"Because latency varies significantly in practice, recent work also assessed the effects of large and sudden latency changes."

论文Pipeline extracted — review needed·指出实践中延迟并非恒定而是会变化

"latency variations are much smaller in practice, with standard deviations in the order of 10 to 100 ms [38, 71]."

论文Pipeline extracted — review needed·用标准差量化实际系统中延迟波动的量级

"we found no evidence that small latency variations affect task time, error rate, or pointing efficiency for moving targets."
