Abstract

Nowadays,there are a lot of assistive products on the market that used to help blind people to guide and prevent to bump into obstacles during their walking. However,when carrying these assistive products,sometimes it would become a burden for visually impaired people as the design of the products is not ergonomics.The users will feel uncomfortable and inconvenience when bringing the assistive device along with them.Thus,this project is conduct to improve the design of the Smart Vibration System inside the goggles so that the users will feel comfortable when wearing on it.The components inside the products will also be modify while remain its functionality.First,a survey has been done among the blind people to understand their needs and wants for the design of goggles.Then several designs idea have been proposed in sketches.Once it is finalized,a CAD model will be generated inside SolidWorks software.All the dimensions will be defined in this stage by considering the system components.Next,the modified product prototype is tested by 15 respondents.As results,the satisfaction of the new design of the goggles has increased from 20% to 73.33%.
