Design Mobility Aids For Bling People Based On User Experience

Human Society is a comprehensive group structure and blind people asspecial group account for a large proportion of the community. Due to theirphysical disability, they lost sight and they and they lose colorful life and freespace affected by the public facilities. However, with the development ofcomputing technology, many mobility aids for blind people transfer visualinformation into auditory or tactile sense with sonars, laser scanners orcameras, and Global Positioning Systems provide blind people withorientation and navigation assistance during their journeys so that they knowthe accurate position at any time. But the question remains that most of thesemobility aids design focused on the technology instead of the user experienceand they could not meet users’ needs, like how to help blind people detectobstacles, identify landmarks or navigate themselves in the indoorenvironment.The objective of this study is to design the mobility aid from the user’spoint of view, finding the blind people’s needs in daily life and creating betteruser experience. This paper will describe the user-centric design process thathow to help blind people living in Edinburgh cross roads independently withthe current traffic facilities.
