Extracting implicit tree structures in spreadsheet calculation / Pertti Saariluoma and Jorma Sajaniemi

Sumario: While information search in user interfaces has mainly been studied with menu systems, this paper extends the problem to spreadsheets, where it is important to extract, i.e. search and store in memory, implicit compatational structures. The central concern is the extent to which subjects'cursor paths follow visible surface structures and the extent to which their information intake is controlled by the deep structure when they extract the computational structure of a spreadsheet. To understand this, cursor movements collected in three experiments in which subjects tried to learn ten different types of spreadsheets are analysed
