Abstract

Information Technology (IT) and Mobile Product Technology (MPT) were not a slogan with the popularity and convenience by

rapid growth of Information Communication Technology (ICT) in the world. The mobile products including PC, notebook, GPS

Navigator, mobile-phone, etc. are used everywhere including the working, living, leisure and entertainment today, especially for

i-phone, i-Pad, Android Tablet have been the necessary equipments for us with the new characteristics of the mobility and

networking communication these years.

There were many user cognitive gaps (UCGs) and misunderstanding between the New Product Development (NPD) and

commercial products according to the related research issues in NPD. The developers always misunderstand and confuse the real

user' requirements because of the ambiguous and fuzzy essential. The developed products (especially for those mobile products)

usually became failures after those products commercialized into market.

As the problems mentioned above, the study uses Innovation Usability Model (IUM) extended from Technology Acceptance

Model (TAM), as a foundational model as an inspective tools for the user-requirements. The IUM also divides the involved users

into the conceptual designers, developers, marketing managers, purchasers and users based on the innovation approach for MPT

development. The IUM can inspect and analyze the priority of the critical design-factors in the new product development and

reduce the fuzzy criteria of the homogeneous and heterogeneous user-requirements. The results of the study can reduce the failures

of the commercialized products in NPD.

Keywords: Innovation Usability Model (IUM); Mobile Product Technology (MPT); New Product Development (NPD); User

Cognitive Gaps (UCGs); Technology Acceptance Model (TAM)
