技术领域technical field
本发明涉及可穿戴式引导技术领域，具体地，涉及一种针对全盲人群的可穿戴式引导设备。The invention relates to the technical field of wearable guidance, in particular to a wearable guidance device for blind people.
背景技术Background technique
盲人就是眼睛患有疾病或受到意外伤害而导致双目失明或单目失明的人，盲人分为先天盲人与后天盲人之分。根据世界卫生组织的估计，全世界有盲人4000万到4500万。我国8300多万残疾人中，视力残疾人1233万，盲人约500万，是世界上盲人人口最多的国家之一。如何解决他们正常学习、工作和生活问题成为社会关注的焦点。A blind person is a person who suffers from a disease or an accidental injury that causes blindness in both eyes or one eye. Blind people are divided into congenital blindness and acquired blindness. According to World Health Organization estimates, there are between 40 and 45 million blind people worldwide. Among the more than 83 million disabled people in my country, 12.33 million are visually disabled and about 5 million are blind. China is one of the countries with the largest population of blind people in the world. How to solve their normal study, work and life problems has become the focus of social attention.
视觉障碍是由于先天或者后天原因致使视觉系统部分或全部丧失功能,以致无法对外界事物进行准确辨识。依据相关规定，视觉未达0.3，或视野在20°以内者即为视觉障碍。根据障碍程度不同，视觉障碍可以分为两类:两眼视力测定值在0.03以上未达0.3或其视野在20°以内为弱视；两眼视力测定值未达0.03为全盲。弱视人群通常可以利用视觉进行日常生活，但是在视物方面有一定障碍，一般需要借助光学辅助设备或特殊放大设备来观察事物。Visual impairment is the partial or total loss of function of the visual system due to congenital or acquired reasons, so that it is impossible to accurately identify external objects. According to the relevant regulations, those whose vision does not reach 0.3, or whose field of vision is within 20°, are considered to be visually impaired. According to the different degrees of impairment, visual impairment can be divided into two categories: amblyopia if the measured value of visual acuity in both eyes is above 0.03 but less than 0.3 or its visual field is within 20°; total blindness is defined as the measured value of visual acuity in both eyes is less than 0.03. People with amblyopia can usually use their vision to carry out daily life, but they have certain obstacles in seeing things, and generally need to use optical aids or special magnifying devices to observe things.
全盲人群所遇到的困难比其他视觉障碍患者人群遇到的困难大得多，全盲人群完全不能依赖视觉进行日常生活，通常只能采取替代方式进行日常生活。例如，利用触觉辅助设备、听觉辅助设备和其它类型辅助设备来替代视觉。大多数信息无障碍技术和设备都可以应用于全盲人群。几乎所有的视力残疾人都可以通过辅助器具补偿功能，不同程度地提高生活质量，参与社会生活。然而，第二次抽样调查显示，我国的视力残疾人中获得辅助器具服务的仅占7.97％；其中城市14.49％，农村5.82％。Totally blind people have far greater difficulties than other visually impaired people. Totally blind people are completely unable to rely on vision for daily life and often have to resort to alternative means to carry out daily life. For example, replacing vision with tactile aids, auditory aids, and other types of aids. Most information accessibility technologies and devices can be used by totally blind people. Almost all visually disabled people can improve their quality of life to varying degrees and participate in social life through the compensation function of assistive devices. However, the second sample survey shows that only 7.97% of the visually disabled in my country receive assistive device services; 14.49% of them are urban and 5.82% are rural.
可穿戴引导设备是指可以通过对于穿戴者周围环境的检测与数据分析提高其在复杂环境中的即使是不接受视觉信息的情况下依然能够应对各种情况的辅助设备。由于全盲人群的特殊性，针对全盲人群的可穿戴引导设备应当属于非视觉助视器，充分利用视觉以外的功能，如听觉、触觉等功能来弥补视觉功能的缺陷从而提高视障者生存质量的辅助器具，涉及到视觉障碍者生活、工作、学习、娱乐等的方方面面。例如：用于日常生活的盲用手机和电话、发声钟表；用于出行的盲杖、盲道；用于学习交流的盲文、点显器、有声读物、各种读屏软件等。Wearable guidance equipment refers to auxiliary equipment that can improve its ability to cope with various situations in complex environments through detection and data analysis of the wearer's surrounding environment, even without receiving visual information. Due to the particularity of blind people, wearable guidance devices for blind people should be non-visual aids, making full use of functions other than vision, such as hearing and tactile functions, to make up for the defects of visual functions and improve the quality of life of the visually impaired. Assistive devices involve all aspects of life, work, study, entertainment, etc. of the visually impaired. For example: mobile phones, telephones, and clocks for the blind used in daily life; blind sticks and roads for the blind; braille, dot displays, audiobooks, and various screen reading software for learning and communicating.
综上所述，针对全盲人群的可穿戴引导设备对于全盲人群的生活、工作有重要意义。现有的种类繁杂的可穿戴引导设备具有功能单一、可扩展性差等特点，不符合易用、适用、简单便携、可扩展等原则。To sum up, wearable guidance devices for blind people are of great significance to the life and work of blind people. Existing miscellaneous wearable guidance devices have the characteristics of single function and poor scalability, and do not meet the principles of ease of use, applicability, simplicity, portability, and scalability.
