An error tolerant memory aid for reduced cognitive load in number copying tasks

Abstract

Number copying tasks are still common despite increased digitalization of services. Number copying tasks are cognitively and visually demanding, errors are easily introduced and the process is often perceived as laborious. This study proposes an alternative scheme based on dictionary coding that reduces the cognitive load on the user by a factor of five. The strategy has several levels of error detection and error correction characteristics and is easy to implement. © 2013 Springer-Verlag Berlin Heidelberg.
