Current interactive systems are criticized tor having complex interfaces that overload users with information. Two possible solutions to manage overload are automatic interfaces that augment user capabilities, and user-controlled systems that provide support. These two types of interfaces introduce a tradeoff: On the one hand, automatic interfaces alleviate workload but create performance problems associated with the absence of control. On the other hand, user-controlled interfaces afford users more control, which may come with additional workload. Based on the analysis of adaptive user interfaces and automation, a model is proposed where automatic and user interface adaptation are in a multidimensional and continuum-based space, allowing for modelling dynamic changes to the roles the human and machine play at various stages of interaction.
