Beginner's Guide to Echolocation for the Blind and Visually Impaired
The use of active echolocation is growing in popularity as a perceptual mobility tool for the blind and visually impaired. As more scientific research is compiled the skepticism around the skill is slowly fading away and making way for accelerated development and implementation of this unique tool. Echolocation is a fundamentally simple skill that many blind people use daily to navigate and understand their environment on a broad scale. With proper implementation, however it can be used to identify precise distance, sizes, shapes, edges and even the density of surrounding objects. This skill is sometimes misunderstood, but it's far more realistic and much easier than you may think. The author demystifies the growing practice of active echolocation in a way that anyone can understand, and gives the reader simple exercises, examples, and lessons as a starting point for launching you into a successful practice of active echolocation. Sound waves - like ripples in a pond - reflect differently off of all objects and surfaces. This makes it possible for the trained ear to distinguish shape, size, distance and material of our surroundings. Musicians will tell you that "reverb" causes each room or surface to have its own unique sound response. With sensitization and applied practice of this skill, it's possible for people with visual impairments all over the world to become increasingly independent, supplementing their existing forms of orientation and mobility with the intrinsic awareness that echolocation can provide. Echolocation requires no special equipment nor any special talent. The human body and mind are truly marvels of nature that grant us with capabilities you may never know you had. If you can hear, you can echolocate. Understanding the simplicity of this skill will allow you to shift your way of thinking to accommodate an expanded awareness of your environment. With this awareness comes independence, confidence, new possibilities and new opportunities.
The Routledge Handbook of Visual Impairment
The Routledge Handbook of Visual Impairment examines current debates as well as cross-examining traditionally held beliefs around visual impairment. It provides a bridge between medical practice and social and cultural research drawing on authentic investigations. It is the intention of this Handbook to provide an opportunity to engage with academic researchers who wish to ensure a coherent and rigorous approach to research construction and reflection on visual impairment that is in collaboration with, but sometimes is beyond, the medical realm. This Handbook is divided into ten thematic areas in order to represent the wide range of debates and concepts within visual impairment. The ten themes include: cerebral visual impairment; education; sport and physical exercise; assistive technology; understanding the cultural aesthetics; socio-emotional and sexual aspects of visual impairment; orientation, mobility, habitation, and rehabilitation; recent advances in "eye" research and sensory substitution devices; ageing and adulthood. The 27 chapters that explore the social and cultural aspects of visual impairment can be taken and used in a variety of different ways in order to promote research and generate debate among practitioners and scholars who wish to use this resource to inform their practice in supporting and developing positive outcomes for all.
The ABCs of Structured Discovery Cane Travel for Children
Structured Discovery Cane Travel (SDCT) is an Orientation and Mobility (O&M) curriculum which focuses on the foundational techniques necessary to develop future independence for students who are blind or visually impaired. The ABCs of Structured Discovery Cane Travel for Children addresses essential non-visual concept development, techniques and mobility skills needed to travel efficiently, gracefully and safely within a myriad of natural environments while using the long, white cane with a metal tip as the primary mobility tool. This curriculum utilizes transformational knowledge and problem-solving opportunities through teachable moments to develop personal reflection and mental mapping which can be utilized post instruction. These students maximize their cognitive intrinsic feedback while completing everyday mobility tasks. Parents and instructors of children who are blind or visually impaired will comprehend the essentials of SDCT by reading The ABCs of Structured Discovery Cane Travel for Children; in addition, they will receive a treasure trove of O&M skill-building activities.
