Scanning using one or two switches allows people with severe physical impairments to use a computer or augmentative communication device. Unfortunately, switch use can be challenging, and switch scanning is an inherently slow method of communication. This two-part series describes the tools and principles to: 1) identify challenges a user may be facing with their switch or scanning system, and 2) recommend and implement adjustments to enhance the user’s performance. Part 2 focuses on using data to make targeted adjustments to a user’s switch or scanning setup, and presents multiple case examples. This process typically yields significant improvements to text entry rate and user satisfaction.

Learning Objectives

  1. Participants will be able to analyze and enhance an individual’s switch use.
  2. Participants will be able to analyze an individual’s current scanning setup and identify inefficiencies or unnecessary challenges presented by the system.
  3. Participants will be able to enhance an individual’s current scanning setup by making targeted adjustments that reduce inefficiency and make it easier to use.
  4. Participants will be able to apply this process to individuals with and without spelling ability and to scanning setups that run on a variety of platforms, including iOS Switch Control as well as more “traditional” AAC software.
