Theoretical framework of universal design principle (UDP) approach considering haptic exploratory procedure (HEP) of visually impaired person in using TRIZ integration.

Abstract

Visually impaired person has a difficulty in identifying the product function and usability. There is a need to integrate haptic exploratory procedure (HEP) of visually impaired person with universal design principle (UDP) in order to construct structural design approach. The purpose of this study is to construct theoretical framework for universal design approach considering haptic exploratory procedure (HEP). This study uses literature on visually impaired person haptic exploratory procedure (HEP) in order to identify the object properties translated by visually impaired person. Then, it uses literature of universal design to identify universal design approach in concept design process. Then, approach of TRIZ is explored in proposing systematic approach. Finally, the results are expected to lead towards model of theoretical framework of universal design approach using TRIZ and HEP. It can provide a helpful foundation for structuring the experiences to develop further the knowledge and understanding of objects for universal design. This theoretical framework contributes in designing structural UDP approach with consideration of visually impaired person HEP. It improves product usability in designing a universal design for visually impaired person.
