We present an interactive method that allows users to easily abstract complex 3D models with only a few strokes. The key idea is to employ well-known Gestalt principles to help generalizing user inputs into a full model abstraction while accounting for form, perceptual patterns, and semantics of the model. Using these principles, we alleviate the user’s need to explicitly define shape abstracti...

Hemispheric differences in the visual system have been well-established, although their exact nature remains under study (Hellige 1990). Thus far, research has focused on the perception of whole objects or scenes. Van Kleeck and Kosslyn (1989) investigated the possibility of lateralization for Gestalt principles using an embedded figures task. They^ found an effect of lateralization, that parts...

The laws and principles which predict how perceptual qualities can be extracted from the most elementary visual signals were discovered by the Their seminal work has inspired visual science ever since, and has led to exciting discoveries which have confirmed the Gestalt idea that the human...

The claims to bring back Gestalt theory into the Neurosciences research field have been laid on both theoretical and experimental grounds. The constraints upon which things look as they do are commonly held as explanatory and predictive phenomenological conditions that supposedly contribute to a better understanding of brain mechanisms underlying the perceptual world structures. On the other si...

The human visual system is highly sensitive to biological motion and manages to organize even a highly reduced point-light stimulus into a vivid percept of human action. The current study investigated to what extent the origin of this saliency of point-light displays is related to its intrinsic Gestalt qualities. In particular, we studied whether biological motion perception is facilitated when...

We show that the performance of existing fault localization algorithms differs markedly for different networks; and no algorithm simultaneously provides high localization accuracy and low computational overhead. We develop a framework to explain these behaviors by anatomizing the algorithms with respect to six important characteristics of real networks, such as uncertain dependencies, noise, an...

Selective attention has been intensively studied using the Stroop task. Evidence suggests that Stroop interference in a color-naming task arises partly because of visual attention sharing between color and word: Removing the target color after 150 msec reduces interference (Neumann, 1986). Moreover, removing both the color and the word simultaneously reduces interference less than does removing...

The paper begins by focusing the basic idea that Gestalt phenomena belong not only to the realm of perception but to the realm of inference. It is shown that Gestalt effects (i.e. the derivability of incompatible indifferent conclusions on the basis of the same background information) often occur both in counterfactual and in ampliative – i.e. inductive and abductive – reasoning. The main thesi...

Games are a popular form of digital entertainment and one elusive question is how complex visual designs affect the player experience. We address one aspect of this topic in terms of similarity of visual features, explored both as an organizing principle in Gestalt psychology and as a theory in visual attention. To address this issue, we developed a 3D railed shooter game with adjustable visual...
