The study of ergonomics evaluation method on hardware and software of mobile phones

Abstract

With the development of technology and society, the demand for ergonomics of hardware and software of mobile phones has becoming increasingly prominent. Therefore, how to improve the user experience and improve the users’ willingness of using the mobile phone from the perspective of ergonomics have become a key concern for handset manufacturers. Based on both the current development trend of the mobile phone industry and the previous relevant conclusions, this paper established a universal evaluation index system on hardware and software of mobile phones and produced a 7-level Likert Scale questionnaire and verified its reliability and validity. In order to verify the practicability of the evaluation index system, the paper used AHP method to calculate the weight of each level of the indexes given by the experts through the score matrix and used weighted total score method to evaluate three different types of mobile phones quantitatively through usability testing. Besides, the paper also verified the mobile phones qualitatively with fuzzy comprehensive evaluation method and obtained the same conclusion as weighted total score method. Furthermore, one-way ANOVA was used to verify the universal applicability of the system in different genders and results showed that gender did not significantly affect the evaluation results concluded by the system.
