Recherche d'information dans les documents numériques : vers une variation des modalités d'exécution procédurale

Abstract : The research activity of information on the internet has become common in our daily life. Despite this fact, it still raises many problems for the user who does not find the information they want or is lost to the amount of information available. This study aims at testing a new patented preview device, enabling users to browse and view pages in depth. The task is to find a target apartment with one or more specific criteria in a real estate agency designed website. Several conditions were tested. The "usual" condition with the classic search features, page by page, the other "transparent" condition which enables you to preview selected pages and select only relevant pages. We are interested in the implementation of cognitive processes to which is added the importance of maintaining the goal of research in working memory, and also in the concept of cognitive load invested in such activity. We use the technique of eye movements among others which determines how a user addresses and searches for information in a digital document. We also compare the performance of this device to a touch pad. The results show significant effects of such previewing device.
