New abacus: a multi-channel interaction device

Multi-channel user interface design is one of the most popular topics in modern human computer interaction studies. It aims at providing users an environment, in which human computer interaction can be realized at anytime and anyplace more naturally and effectively. Abacus calculation requires integration of multiple cognitive functions including number recognition, retrieval of arithmetic facts, temporary storage of intermediate results, and manipulation of mental representations. It relies on the process from perception through visuospatial panel to central executive, in which information is channeled bi-directionally. Phonological loop, however, is seldom involved in the calculation process. Therefore, it is intuitively wondered whether it is possible to involve also phonological loop in abacus calculation as an extra channel.
