More about VI

  • Socially more isolated and less assertive than other children

  • Experiences must be gained by using the remaining senses, especially touch and hearing

  • Learn to travel safely and efficiently in the environment using a variety of orientation and mobility skills (i.e., competencies for traveling safely and efficiently through one’s environment) and tools, such as the long cane

  • Even with effective mobility skills, they still have some level of detachment from the environment because vision disables immediate and direct control of the environment.
