A Weighted QFD-Based Usability Evaluation Method for Elderly in Smart Cars

Abstract

The aim of this research is to develop a quantitative usability evaluation method (UEM) for elderly drivers, which has different weight values on each factor concerning physical and cognitive context of elderly drivers. An analysis of the relationship between universal design guidelines for elderly drivers and usability principles was conducted by using the quality function deployment method. In addition, developmental priorities are derived from analysis results of difficulty in achieving performance improvement, max relationship values, and relative weight. Furthermore, n and positive relationships among the universal design guidelines are defined by means of relationship analysis. Combining these results, a quantitative evaluation guideline for elderly drivers is derived, and based on the context and developmental goals of the developer, selective design is facilitated. The proposed UEM is compared with existing UEM in terms of thoroughness, validity, and effectiveness.

A humanistic-care factors application hierarchical design-model for intelligent elderly products

“…And some scholars put forward the user-centered design method for the design of smart clothing for the elderly and suggested that the user's evaluation tendency of smart clothing should be involved in the design process [ 10 ]. Some scholars used Quality Function Development (QFD) to study the relationship between universal design criteria and usability principles to establish a usability evaluation method for intelligent elderly vehicles [ 11 ]. To reduce the subjectivity of choosing the design scheme of intelligent elderly accompanying products, some scholars put forward an evaluation method of the design scheme of healthy elderly accompanying products [ 12 ].…”

Commonly Used External TAM Variables in Virtual Reality, E-Learning and Agriculture Applications: A Literature Review Using QFD as Organizing Framework

“…Many authors have implemented the QFD in their studies addressing the design of products and services with particular focus on customer experience and alternative ways to capture user's feedback as in the works by Iranmanesh et al, Choi et al, Vezzetti et al, Violante et al, Sun et al [35][36][37][38][39]. The reputation of the QFD as a reference framework for design and quality management can be attributable to the multiple advantages it offers.…”
