Usability Study Of Smart Toothbrush APP User Interface

With the rapid development of AI technology and Internet of Things industry,traditional products or services are evolving towards informatization and intelligence.In the process of product transformation and upgrading,the information interaction between products and users is more extensive and in-depth,and the human-computer interaction interface between them becomes more complex and diversified.Based on this,this paper takes the smart toothbrush APP user interface as the research object,and discusses its usability.The purpose is to effectively improve the design quality of its human-computer interaction interface.This paper takes the smart toothbrush software development project as the research support,and uses the method of questionnaire survey and experiment to obtain the raw data of user demand.Firstly,the Kano model is used to extract the functional requirements of the smart toothbrush APP,and the satisfaction analysis of the functional requirements is carried out to determine the priority of the expected functional requirements.Secondly,based on the availability framework of researchers such as Nielsen,the authors established seven evaluation dimensions for the user interface usability evaluation of intelligent products,and based on the product function requirements,combined with the expert review method,the usability evaluation of the smart toothbrush APP user interface was obtained 17 indicators of the system.Then the questionnaire survey and experimental test method are used to obtain the user's evaluation data.The smart toothbrush APP user interface mobile usability evaluation system is combined with the TTF model,and the SPSS software is used to perform regression analysis on the data to calculate the influence of the smart toothbrush APP user interface.Key indicator elements and get the actual priority of each functional requirement.Finally,compare with the expected function priority,find out the difference part,analyze the key indicators,optimize the design of the lower evaluation index of the key indicators,and improve the user satisfaction of the user interface.This research method has certain theoretical reference and design practice guiding value for the availability of user interface of similar intelligent equipment.
