Modeling One-Switch Row-Column Scanning with Errors and Error Correction Methods

摘要

Single switch scanning has lots of different configuration options. One way to choose the most appropriateconfiguration for a client is to use a model to predict performance under different configurations. Most existing modelsexpect error-free performance, however, and none integrates all the types of errors that can occur and the variety of errorcorrectionmethods that are available. A model is presented which predicts user performance for single-switch rowcolumnscanning with errors and error-correction methods. The model is used to draw conclusions about the utility ofdifferent error-correction methods.
