Modeling One-Switch Row-Column Scanning with Errors and Error Correction Methods
Richard C. Simpson · The Open Rehabilitation Journal · 2011
Single switch scanning has lots of different configuration options.One way to choose the most appropriate configuration for a client is to use a model to predict performance under different configurations.Most existing models expect error-free performance, however, and none integrates all the types of errors that can occur and the variety of errorcorrection methods that are available.A model is presented which predicts user performance for single-switch rowcolumn scanning with errors and error-correction methods.The model is used to draw conclusions about the utility of different error-correction methods.
