Research Of The Assistive Device Emotional Design For Visual Disabled Considering Psychological Characteristics

As a special group of social life,disabled people faced many practicaldifficulties.Its sound easily lead to a negative attitude towards the crowd andpopulation psychological divide of the disabled. To avoid the negativepsychological of disabled caused by poorly design when using assistivedevice,designers should add the appropriate emotional elements in the designingof ancillary products.This paper studies the visual departure emotional disabilities ancillaryproducts designed from two angles.First of all,analyzed the mainpsychological characteristics of visual disability,using SCL-90SymptomChecklist questionnaire research visual disabilities in process find out the mainpsychological characteristics of visual disabilities,and analyze the expressionand form factor of psychological characteristics.In basic of three mainpsychological characteristics respectively formulate the recommendation of thedirection of ancillary products.Secondly,using the principle of instinct level,behavior level and reflection level in emotional design guide the auxiliaryappliance design method research for people with visual disabilities.Instinctivelevel design methods include styling elements,color elements and textureelements;Taking part of the Kansei engineering principle and sensory functioninto account in auxiliary products to build emotional design.Reflection leveldesign derived from the user emotional experience of ancillary product includesthe sense of security, the operation of pleasure and a sense of satisfaction orself-realization.Final based on the derived ancillary products emotion designmethod And substituting part of Kansei engineering and ergonomic design theoryto guide practice--electronic cane emotional design.In order to verify thefeasibility of the method design in assistive device， take the emotionalsatisfaction survey of the case. Through the cycle which that theory could instruct the practice, practicecould prove the theory, making it possible that the emotional design couldadded in auxiliary products for the disabled to provides a broader way ofthinking for the future design of ancillary products.
