淺談移動產(chǎn)品的交互效率(留存版)
【正文】 升單位任務(wù)的交互效率。3. 可用性評估中可以有針對性地做一些檢查。實(shí)際操作中，用戶的操作行為不會像GOMS模型那般理想。例如：目前手機(jī)搜索主要依靠按鍵打字的方式來輸入搜索關(guān)鍵詞。關(guān)于交互效率ISO 9241對效率（efficiency）有這樣的描述：In HCI or Usability terms, efficiency is measured as the resources expended by the user in relation to the accuracy and pleteness of goals achieved. High efficiency is achieved when the user reaches his/her goals while expending as few resources as possible according to the mentioned ISO standard.簡而言之：效率是衡量用戶任務(wù)正確度和完成度與所消耗的資源量關(guān)系的指標(biāo)。|本文無意再在具體操作層面做具體的比較，而試圖從任務(wù)模型的
