傳真機操作按鍵的認知心智模型分類之研究

A study on the Groupings of Cognitive mental-model with multi-function FAX

本研究計畫試圖建立使用者面對複雜的操作行為，其內在的認知心智模型。首先經由文獻探討等方式，了解使用者的認知過程模式，並據此假說初步建立一個通用性的認知心智模型。接著以一個須互動式操作的產品〔SANYO多功能傳真機〕為研究對象，透過先期的預備實驗設計並修正實驗細節，然後開始抽樣進行實驗。令受測者在完全了解其全部按鍵功能之後，將所有操作按鍵分類，其次將所有受測者的按鍵分類結果，進行集群分析從而得到使用者的幾種類別。接著再將此數類別的使用者，分別與其按鍵分類結果作一次比對分析，即可得到各類別使用者心智模型之資訊構成層屬關係，以建立各類別使用者認知的心智模型。最後再將此結果與最初之認知過程模式相互比較，推論各類別使用者操作流程的差異。據此所建立出來的模型化設計概念，不但可作為設計者的依循準則，更可藉此拉進設計者與使用者在認知心智模型上的差距，讓產品變得更容易被理解，其與使用者間的互動性關係也得以更形親切。

The purpose of this project is to establish the cognitive mental model of a user who faces complicated operation behavior. Firstly, a general cognitive mental model based on user's cognitive procedure model proposed in literature is established. An interactive operating product （for example: a multi-function FAX machine） is the research object. After fully understanding the function of each keys, the subject should sort all the function keys. Then, we analyze the key types and the user types by cluster analysis. The user types and the key types will be analyzed contrastly. By this way, the hierarchy relationship in the information construction of various types of user's mental cognitive model can be obtained. At the same time, we calculate its hierarchy distance to establish various user's cognitive mental model and illustrate the information construction. At last, we compare this research with previous cognitive procedure model and find out the interactive operation procedure of each user type. Therefore, products which designed by these rules are easier to understand than others, and more friendly an interactive user interface.
