On the use of product innovation in the design process of the research

This study is based on "user at the core" of human nature to study the chemical product design of the spindle, the OHP by the general market for the subject matter of the projector, to explore the field of industrial design in consumer electronics products, "the use of "problem. The study found that by the terms of the duration of the project to test the operational problems as the definition of degree of difficulty, can be summarized into easy, medium, three levels of difficulty. Which started in the projector part of the two 2,3, and in the incorporated part Of the D, E 2 are the use of bad design. In addition the graphical instructions in haste, but also allows users to easily confused, they are advised in future studies to improve the situation.
