Thewalking stick is reasonable in design, compact in structure and convenient to use.

Description

technical field [0001] The invention relates to crutches for the blind. Background technique [0002] At present, many designers have turned their attention to the field of "designing for the blind", but it is rare to see blind people using these products, and it is rare to see blind people doing outdoor activities. One of the reasons is that these products designed to help the blind and help the blind travel cannot effectively serve the blind. [0003] More and more designers and related practitioners are focusing on "designing for the blind", and the concepts and forms of walking aid products for the blind are also varied. Most of them can make up for the defects of blind users through sensory transformation. Whether it is converting visual information into auditory or tactile information to feed back to users, it is a relatively appropriate way of human-computer interaction. [0004] However, a considerable part of the means to promote the concept of sensory transformat...

Problems solved by technology

However, the above-mentioned way of travel cannot be continued as an ideal way because of its own limitations.

Therefore, the field of conceptual research for blind mobility products still requires significant investment
