Research On The Design Of Wearable Devices For Preschool Children Based On Developmental Psycholigy

As a new mobile Internet era comes,smart mobile terminal is a necessity for work and life,and become the main carrier of information transmission and service.According to market research,China's smart wearable products gradually get close to the children users and showing a trend of younger age tendency,children currently on the market wearable product quality is uneven and the age span,meet the psychological and physiological characteristics of children of all ages are very few.The theory that about a wearable product design and development for children intelligence is not perfect,it is difficult to be truly from the user's perspective,the real needs of children as the starting point for how to design to meet the needs of the children of wearable products worth pondering.This paper studies leading children wearable devices as the research object,with the development of psychology as the main theoretical basis of preschool education for children of product design,analysis of preschool children study of qualitative and quantitative methods for the digital information era,science research leading children wearable devices interaction design principles and methods,in order to promote the development of science leading children wearable devices.Firstly,physiological,cognitive and emotional perception,such as the development of the characteristics of literature analysis of leading children users;using literature analysis,case studies,interviews with shadow method,qualitative analysis method to analyze the issues associated with the market background,understand the research status at home and abroad,the status analysis of life with the demand of preschool children,and to observe the living environment;combined with the current situation and demand of preschool users,and that preschool children can be found status and requirements of wearable products,developed through brainstorming to preschool children and parents issued questionnaire can be expected to wear the product,get feedback through quantitative research in a large scale,the accumulation of reliable theoretical basis for the design.On the basis of investigation and research,summarizing the four principles that are targeted,simplicity,ease of use,the secrecy,for the interactive design of preschool children wearable devices.According to the characteristics,psychological perception,cognitive and emotional development of various elements of preschool children,building the interactive design method of wearable devices,which is conform to the user perception,to attract users attention,help the user focus,preschool children rich user experience,to provide guidance for its development direction.From the point of design practice,using the principles and methods of interactive design proposed in the preceding paper,we designed a wearable product of preschool children "Kip".Through the user test in usability testing to evaluate the effectiveness,efficiency and satisfaction index of the product.According to the test,the average results of the three indexes are greater than 6,which indicates the will of users to use the wearable devices.The results of open interviews are improved.
