隨著通訊科技的演進，加上硬體技術的發展，讓手機從原始的語音傳輸演變到多功能智慧型，徹底改變手機應用的範圍。而在這科技進步迅速的時代，智慧型手機產品的生命週期愈來愈短、汰換率愈來愈高，導致相關業者的競爭也愈來愈激烈。為了因應日漸嚴苛的挑戰，各家業者無不努力將產品與應用服務推陳出新，但是使用者真正使用到的功能又有多少？

為了讓手機的服務能夠和使用者真正的聯結，必須要具備良好的操控介面，然而業者所認定的需求不一定符合使用者的需求，忽略使用者的想法往往會導致產品的失敗，掌握使用者的需求才是成功的關鍵。因此本研究以科技接受模型(TAM)為理論基礎，加入創新擴散理論(IDT)與歸納的人機介面(或稱為User Interface，UI)設計原則、趨勢(多樣性、直覺性)做為外部變數，進一步探討智慧型手機之使用態度。

研究結果：(1)多樣性、相容性正向影響有用性認知，直覺性對有用性影響不顯著；(2)多樣性、直覺性、相容性正向影響易用性認知；(3)有用性認知、易用性認知、相對優勢正向影響使用態度；(4)可試驗性、可觀察性對使用態度影響不顯著，但可試驗性與使用態度呈現負相關。

With the evolution of communication and hardware technology, mobile phones evolved from the voice communication to the multi-function, the scope of mobile phone applications had completely changed. In this era of rapid technological progress, the shorter product lifecycle and higher replacement rates of smartphone induce competition in the relevant industry become more intense. Various industries introduce new products and applications in efforts to cope with the increasing challenges, but how many features are used by users?

In the cause of real connection between mobile phone and users, the control must with a good user interface, but the needs of industries identified do not necessarily conform to user''s needs, ignoring the user''s thoughts often lead to product failure, master the needs of user is the key to success. Therefore, this study uses the Technology Acceptance Model (TAM) as the theoretical foundation, adds the Innovation Diffusion Theory (IDT) and the induction of the human-machine interface (or User Interface, UI) design principles (diversity, intuition) as external variables, to further explores the attitude of using smartphone .

The results: (1) diversity, compatibility, positive influence on perceived usefulness, but intuition don''t influence significantly; (2) diversity, intuition, compatibility, positive influence on perceived ease of use; (3) perceived usefulness, perceived ease of use, relative advantage positive influence on the attitude of use; (4) trialability, observability influence on the attitude of use is not significant, and trialability existence negative relationship with the attitude of use.
