“…Adrien Brilhault et al (2011) [ 28 ] proposed a smart cane that integrates GPS (global positioning system) and visual positioning, which can identify markers in the surrounding environment by using cameras and realize navigation function by using GPS. Similarly, MY Fan et al (2014) [ 52 ] equipped an RGB-D depth camera, ultrasonic sensor, GPS and GPRS module on the blind cane. Using RGB-D depth camera to capture dynamic visual environment information, GPS and GPRS modules can obtain the target and the current position of the smart cane and upload the data to the remote center and using the ultrasonic module to help the visually impaired avoid obstacles.…”

Laser sensing and vision sensing smart canes can improve the convenience of travel for the visually impaired, but for the present, most of the system functions of laser sensing and vision sensing smart canes are still defective. Guide equipment and smart blind canes are introduced and classified first, and the smart blind canes based on vision sensing, laser sensing and laser vision sensing are investigated, respectively, and the research status of laser vision sensing smart blind canes is sorted out. The advantages and disadvantages of various laser vision sensing smart blind canes are summarized, especially the research development of laser vision fusion as the core of new smart canes. The future development prospects of laser vision sensing smart blind cane are overviewed, to boost the development of laser vision sensing smart blind cane, to provide safe and efficient travel guarantee for the visually impaired.

Across the world, there are approximately 253 million people with vision impairments, and assistive devices have constantly been in demand. Advanced research has led to the development of numerous assistive devices for blind people and visually impaired people (VIP) to improve their quality of life. An overview of these different types of assistive devices such as canes, glasses, hats and gloves is presented in this survey. A FCBPSS (F: function, C: context, B: behaviour, P: principle, S: state, S: structure) architecture of visual impairment assistance system is preliminarily proposed to allow other researchers to design the assistive devices with the good experience and the high performance for blind people and VIPs in the future. As VIPs and blind people may have different behaviour patterns, a criterion for classifying different types of vision impairments is presented. Subsequently, we classify the substitutive senses for visual perception into five categories: vision enhancement, audition, somatosense, visual prosthesis, and olfactory and gustation. Two commonly used feedback forms, namely audition and vibration, are elaborated.Based on literature survey, we also present a summary prospective of the development of assistive devices: add more sensing and feedback modules, use the knowledge of perception mechanism and behaviour pattern as the design guideline and design more reliable validation experiments.
