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

Quist, W. (author), Van Hees, R. (author), Naldin, S. (author), Nijland, T. (author)By means of a questionnaire a study was carried out to investigate the perception of small scale damage and repairs of natural stone used in buildings. Participants were asked to evaluate damage to natural stone shown on pictures. They were also asked to give their opinion on interventions needed to preserve or restore the material. Significant...conference paper 2008

Ozcan-Vieira, E. (author)Products are ubiquitous, so are the sounds emitted by products. Product sounds influence our reasoning, emotional state, purchase decisions, preference, and expectations regarding the product and the product's performance. Thus, auditory experience elicited by product sounds may not be just about the act of hearing or a sensory response to an...doctoral thesis 2008

Christiansson, G.A.V. (author), Van der Linde, R.Q. (author), Van der Helm, F.C.T. (author)Human task performance using teleoperator systems depends on the physical and controlled parameters of the system. Two teleoperated grasping tasks—size and stiffness discrimination—were studied to investigate how changes in system parameters influence human capabilities. The device characteristics altered were teleoperator stiffness (size and...journal article 2008

Hoffmann, S. (author)Risk awareness and personal preparedness are seen to be important parameters in an integrated risk management scheme today. This study is contributing to the knowledge base about the perception of risk. Regarding the risk of storm-surges, an assessment of the perception and the status of personal preparedness of the people are addressed in an...report 2008

Heyndrickx, I. (author), Kaptein, R. (author)A lot of current 3D displays suffer from the fact that their spatial resolution is lower compared to their 2D counterparts. One reason for this is that the multiple views needed to generate 3D are often spatially multiplexed. Besides this, imperfect separation of the left- and right-eye view leads to blurring or ghosting, and therefore to a...conference paper 2009

Ten Holt, G.A. (author), Arendsen, J. (author), De Ridder, H. (author), Van Doorn, A.J. (author), Reinders, M.J.T. (author), Hendriks, E.A. (author)Current automatic sign language recognition (ASLR) seldom uses perceptual knowledge about the recognition of sign language. Using such knowledge can improve ASLR because it can give an indication which elements or phases of a sign are important for its meaning. Also, the current generation of data-driven ASLR methods has shortcomings which may...conference paper 2009

Steinführer, A. (author)The paper draws lessons from our empirical investigations in Germany, Italy and England/Wales in a very specific perspective: It formulates recommendations for flood risk management with people at risk. Thus it tries to shed light on the views of this important but often neglected group of stakeholders. Our addressees are flood risk...report 2009

Teunissen, C. (author)Over the last decade, consumer television sets have substantially increased in screen size, with screen diagonals up to 65-inch and beyond. At the same time, their thickness has decreased to only a few centimeters. Right from the start, this combination has been highly appreciated by consumers, resulting in a fast acceptance of flat-screen...doctoral thesis 2009

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

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

Marchand, M. (author)The aim of this report is to document the output of the three workshops and the questionnaire. The results of the Flood risk analysis has been reported in another Floodsite report: De Bruijn et al., 2008. For a complete description of the Schelde pilot study reference is made to Chapter 8 of the FLOODsite book on pilot sites (Schanze, in prep.).report 2009

Slinger, J.H. (author)At the 2008 System Dynamics Conference in Athens a survey of the understanding and expectations of conference participants regarding model analysis was conducted. Respondents included both those active in research on formal model analysis methods and those only vaguely familiar with the term. Results from the survey are presented and discussed...conference paper 2009

Choy, H.Y. (author)With the introduction of LED lighting, nowadays designers and architects have more flexibility to evoke emotions and create certain atmospheres in a space by means of artificial lighting. The perceived atmosphere in a space is an experience of the surroundings in relation to ourselves; it is an affective evaluation of the environment (Scholten...master thesis 2009

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

Bittermann, M.S. (author)Design is complex. This is because it involves conflicting goals that are often vague. Also, prior to the design it is generally not clear how important goals are relative to each other. And finally the amount of possible solutions is large in general. These bottlenecks are addressed in this thesis. A novel approach for design is proposed, where...doctoral thesis 2009

Arendsen, J. (author)This dissertation presents the results of a series of studies on the appearance of manual movements in gestures. The main goal of this research is to increase our understanding of how humans perceive signs and other gestures. Generated insights from human perception may aid the development of technology for recognizing gestures and sign language...doctoral thesis 2009

Yang, Z. (author)In many public places multiple sensing devices, such as cameras, are installed to help prevent unwanted situations such as aggression and violence. At the moment, the best solution to reach a safe environment requires human operators to monitor the camera images and take appropriate actions when necessary. In the wake of the terrorist attacks of...doctoral thesis 2009
