Van Doorn, A.J. (author), Koenderink, J.J. (author), Leyssen, M.H.R. (author), Wagemans, J. (author)We study the effect of stylistic differences on the nature of pictorial spaces as they appear to an observer when looking into a picture. Four pictures chosen from diverse styles of depiction were studied by 2 different methods. Each method addresses pictorial depth but draws on a different bouquet of depth cues. We find that the depth...journal article 2012

Koenderink, J.J. (author), Van Doorn, A.J. (author)“Pictorial space” is the mental structure that appears to be the scaffold for the visual awareness when looking “into” (as opposed to “at”) a picture. Its structure differs from the “visual space” that is the scaffold for the visual awareness when looking into the scene in front of the observer. The structure of pictorial space has been probed...journal article 2012

Sleenhoff, S. (author), Osseweijer, P. (author)With a mandatory labeling scheme for GM food in Europe since 2004 measuring actual consumer choice in practice has become possible. Anticipating Europeans negative attitude toward GM food, the labeling was enforced to allow consumers to make an informed choice. We studied consumers actual purchase behavior of GM food products and compared this...journal article 2013

Volcic, R. (author), Wijntjes, M.W.A. (author), Kool, E.C. (author), Kappers, A.M.L. (author)The simple experience of a coherent percept while looking and touching an object conceals an intriguing issue: different senses encode and compare information in different modality-specific reference frames. We addressed this problem in a cross-modal visuo-haptic mental rotation task. Two objects in various orientations were presented at the...journal article 2010

Mugge, R. (author)People use the appearance of products as a cue for evaluating functional attributes at purchase. This research provides an understanding of this form-function interdependency by investigating the effect of a business-like personality in product appearance on the perceived performance quality of the product. A business-like personality is...journal article 2011

Van Doorn, A. (author), Koenderink, J. (author), Wagemans, J. (author)We address the topic of “pictorial depth” in cases of pictures that are unlike photographic renderings. The most basic measure of “depth” is no doubt that of depth order. We establish depth order through the pairwise depth-comparison method, involving all pairs from a set of 49 fiducial points. The pictorial space for this study was evoked by a...journal article 2011

Richards, W. (author), Koenderink, J.J. (author), Van Doorn, A. (author)Unlike the Metelli monochrome transparencies, when overlays and their backgrounds have chromatic content, the inferred surface colors may not always be physically realizable, and are in some sense “imaginary.” In these cases, the inferred chromatic transmittance or reflectance of the overlay lies outside the RGB spectral boundaries. Using the...journal article 2009

Wijntjes, W.A. (author), Doerschner, K. (author), Kucukoglu, G. (author), Pont, S.C. (author)Among other cues, the visual system uses shading to infer the 3D shape of objects. The shading pattern depends on the illumination and reflectance properties (BRDF). In this study, we compared 3D shape perception between identical shapes with different BRDFs. The stimuli were photographed 3D printed random smooth shapes that were either painted...journal article 2011

Wijntjes, W.A. (author), Pont, S.C. (author)It has recently been shown that an increase of the relief height of a glossy surface positively correlates with the perceived level of gloss (Y.-H. Ho, M. S. Landy, & L. T. Maloney, 2008). In the study presented here we investigated whether this relation could be explained by the finding that glossiness perception correlates with the skewness of...journal article 2010

How consumers perceive product appearance; the identification of three product appearance attributesBlijlevens, J. (author), Creusen, M.E.H. (author), Schoormans, J.P.L. (author)The appearance attributes of designed products noted in the literature often reflect what designers themselves perceive in a product design. This present research, however, provides knowledge on how consumers perceive product appearance by identifying appearance attributes that consumers use to distinguish the appearances of durable products....journal article 2009

De Greef, T.E. (author), Leveringhaus, A. (author)Advanced warfare technologies (AWT) create unprecedented capabilities to control the delivery of military force up to the point, some argue, that we are loosing humanity. But dependence on them generates difficult moral challenges impacting the decision-making process, which are only beginning to be addressed. In order to arrive at an informed...journal article 2015

(author)The objective of this study was to evaluate differences in driving performance, visual detection performance, and eye-scanning behavior between glaucoma patients and control participants without glaucoma. Glaucoma patients (n = 23) and control participants (n = 12) completed four 5-min driving sessions in a simulator. The participants were...journal article 2013

Schifferstein, H.N.J. (author), Desmet, P.M.A. (author)To determine the roles the sensory modalities play in user-product interactions, one modality was blocked during the execution of eight simple tasks. Participants reported how they experienced the products and how they felt during the experiment. Blocking vision resulted in the largest loss of functional information, increased task difficulty...journal article 2007

Read, S.A. (author)This commentary on Søren Riis’s paper “Dwelling in-betweenwalls” starts from a position of solidarity with its attempt to build a postphenomenological perspective on architecture and the built environment. It proposes however that a clearer view of a technological structure of experience may be obtained by finding technological-perceptual wholes...journal article 2011

Wijntjes, M.W.A. (author)The perception of pictorial surfaces has been studied quantitatively for more than 20 years. During this time, the “gauge figure method” has been shown to be a fast and intuitive method to quantify pictorial relief. In this method, observers have to adjust the attitude of a gauge figure such that it appears to lie flat on a surface in pictorial...journal article 2011

Wijntjes, M.W.A. (author), Volcic, R. (author), Pont, S.C. (author), Koenderink, J.J. (author), Kappers, M.L. (author)We studied the influence of haptics on visual perception of three-dimensional shape. Observers were shown pictures of an oblate spheroid in two different orientations. A gauge-figure task was used to measure their perception of the global shape. In the first two sessions only vision was used. The results showed that observers made large errors...journal article 2009

Wagemans, J. (author), Van Doorn, A.J. (author), Koenderink, J.J. (author)We propose a novel method to probe the depth structure of the pictorial space evoked by paintings. The method involves an exocentric pointing paradigm that allows one to find the slope of the geodesic connection between any pair of points in pictorial space. Since the locations of the points in the picture plane are known, this immediately...journal article 2011

Wastiels, L. (author), Schifferstein, H.N.J. (author), Wouters, I. (author), Heylighen, A. (author)Designers’ visual way of knowing and working tends to be highly valued in design research. In architecture such an approach is increasingly criticized. Since people experience buildings with all their senses, architects’ visual focus is said to the run the risk of disregarding non-visual aspects. This study focuses on the visual and tactile...journal article 2013

Wijntjes, M.W.A. (author), Kappers, A.M.L. (author)It is known that our senses are influenced by contrast effects and aftereffects. For haptic perception, the curvature aftereffect has been studied in depth but little is known about curvature contrast. In this study we let observers explore two shapes simultaneously. The shape felt by the index finger could either be flat or convexly curved. The...journal article 2009
