The Equipments Of Orientation And Mobility For The Blind Man

In order to help the blind people know that where they are,where to go and how to reach the destination safely,in this paper,the writer analysed the characteristics and needs of the blind.Based,focus the product users on the group of the young total blindness,and then,the writer had one on one interviews with the product users,analyzed the user demand and established the typical user model,in order to depth exploration analysis travel scene and user process of the young total blindness,which summed up the user's travel histories and refine the user travel demand.Then,researched the development and status of existing blind guide at home and abroad,detailed analysis of the new guide device,and compared the advantages and disadvantages of all kinds of products,thus it could provide technical support to the.In the behinds,after viewing the literature and under the background of the design theory,the writer summed up the design principles for the young total blindness.In order to solve the problem of young total blindness oriented action,and make the investigation of the demand into the corresponding function,the writer researched the related function of technology and support,further confirmed the feasibility of the product design,then the design beginning,from the operating handle device design,structure design,interior design,color design,machine size design,in the process,optimizing the user travel process in the other hand,so that the outing of young total blindness is no longer difficult,this process is based on the consideration of the different schemes of sketching,after the comparative analysis of different schemes,the detail design for one of the schemes,then design the appearance,structure,material,color,surface treatment technology of the product,the final design presented in the form of a model.
