The principal argument of the paper is that node-and-link presentation
logic supports improved usability (for both providers and
preventive-care-oriented recipients) on two potential levels: the cognitive
and the technical. The cognitive aspect is achieved through the
resultant presentations themselves; the technical aspects are workflow
related and advocated through the techniques of touchscreen, gesturebased
(or voice-activated) polyhedric-interface navigation. Node-andlink
models are well leveraged via gesture-based interoperability and
node-and-link presentations are easily navigated through 3D polyhedric
representations.
