人類處理器模型human processor model)係認知心理學上嘅一個理論模型,主要攞嚟估計一位用家做某一樣認知作業(例如係撳某一個掣)要用幾耐嘅時間;根據呢個模型,人喺做認知作業嗰陣會經過一柞基本步驟,包括咗

即係好似下圖噉[1]

人類處理器模型喺人機互動(human-computer interaction;思考人同電腦之間嘅互動嘅領域)分析(例如係對易用性嘅分析)上相當有用。例:一班設計者家陣想設計網購網站,佢哋用心理實驗嘅方法知道咗,用家對眼望勻嗮成個網頁平均要用 230 毫秒,理解得到嗮望到嘅係啲乜就平均要用 300 毫秒,做決策(「買唔買」同埋「要買邊樣嘢」)就平均要用咁多咁多毫秒,而腦部訊號落手嘅肌肉令手做出「撳掣」嘅動作就平均要用咁多咁多毫秒... 等等;將呢啲數值加埋之後,班設計者就可以估計到用家平均會喺個網頁上逗留大約幾耐嘅時間[1][2]
