Information Visualizations (InfoViz) are systems that require high levels of cognitive processing. They
revolve around the notion of decoding and interpreting visual patterns in order to achieve certain
goals. We argue that purely designing for the visual will not allow for optimum experiences since there
is more to InfoViz than just the visual. Interaction is a key to achieving higher levels of knowledge. In
this position paper we present a different perspective on the underlying meaning of interaction, where
we describe it as incorporating both the visual and the physical activities. By physical activities we
mean the physical actions upon the physical input device/s. We argue that interaction is the key
element for supporting users’ subjective experiences hence these experiences should first be
understood. All the discussions in this paper are based upon on going work in the field of visualizing
the literature knowledge domain (LKDViz)
