An Objective Means of Establishing Optimal Information Transmission Rates in Individuals with Disability

摘要

The objective of this paper is to demonstrate that contextual effects on a single switch access pathway can be meaningfully ascertained by estimating the rate of information transmission in the human communication channel. Using data from human participants, we illustrate a number of ways in which mutual information could be used to quantify switch usage within an experimental setting. This mutual information framework may inform the design of access pathways. It may eventually lead to the development of context-aware access pathways. Such systems can potentially sense and compensate for the negative effects of certain hindering contextual factors or exploit facilitating factors to improve the robustness of an access pathway.
