All these conceptual activities are performed with one single core interaction.
However, there are also examples, where conceptual activities are supported by a
combination of several core interactions. In PapierCraft, the user creates a hyper-
link between two paper pages by first highlighting (
inking
) the passages that shall
be linked and then
bridging
them with two consecutive markings on both pages.
Moreover, PapierCraft supports creating physical collages: A user first physically
combines
two paper sheets by positioning one besides the other in a way that the
margins slightly overlap. Drawing an associating line then digitally
bridges
both
sheets. The Digital Desk allows users to select document snippets with a pen ges-
ture (
inking
)andthen
combine
these snippets in a physical and digital collage.
The novel interaction techniques presented in this topic draw upon single core
interactions as well as upon combinations of them. Table 3.2 includes an overview
of these strategies, which will be discussed in the following chapters.
