Étude de la performance de quatre modèles de présentation de formulaires sur un assistant numérique personnel

The goal of this study is to compare the performance of four models of presentation of forms on PDA, in terms of information search time by subjects, as a function of the length of these forms. We developed two models of form presentation on PDA, namely flip zooming and arborescence. We compared their performance in terms of information search time with that of widely used models, namely scrolling and menus, while taking into consideration the length of these forms. Thirty-six subjects participated to an experiment where their task consisted in searching for information as rapidly as possible in forms of three different lengths on PDA. Results show that all lengths of forms together, the arborescence model is the most rapid one and the most appreciated by subjects, followed by the menu model, the scrolling bar model, and the flip zooming model. They also show that the more the form is long, the more the relative performance of the scrolling bar model diminishes, and the more that of the arborescence model augments. Even though results of the flip zooming tests were mediocre, this model has great potential since the expert results confirmed its superiority relative to the menu and scrolling models.
