Dijk, E.O. (author), Nijholt, A. (author), van Erp, J.B.F. (author), van Wolferen, G. (author), Kuyper, E. (author)Stimulation of the tactile sense or the hearing sense can be used to improve a person's health and well-being. For example, to make someone relax, feel better or sleep better. In this position paper, we present the concept of auditory-tactile stimulation for health and well-being. Through carefully selected audio-tactile stimuli a person's...article 2013

Toet, A. (author)The predictions of 13 computational bottom-up saliency models and a newly introduced Multiscale Contrast Conspicuity (MCC) metric are compared with human visual conspicuity measurements. The agreement between human visual conspicuity estimates and model saliency predictions is quantified through their rank order correlation. The maximum of the...article 2011

Shahid, S. (author), Krahmer, E. (author), Neerincx, M. (author), Swerts, M. (author)We describe and evaluate a new interface to induce positive emotions in users: a digital, interactive adaptive mirror. We study whether the induced affect is repeatable after a fixed interval (Study 1) and how copresence influences the emotion induction (Study 2). Results show that participants systematically feel more positive after an...article 2013

van Erp, J.B.F. (author), Oving, A.B. (author)In this study, the determinants of head motions (rotations) when driving around bends were investigated when drivers viewed the scene through a head-mounted display. The scene camera was either fixed or coupled to head motions along 2 or 3 axes of rotation. Eight participants drove around a triangular circuit and the range and speed of head...article 2012

Krul, A.J. (author), Daanen, H.A.M. (author), Choi, H. (author)Background: Self-reported values of height and weight are used increasingly despite warnings that these data - and derived body mass index (BMI) values - might be biased. The present study investigates whether differences between self-reported and measured values are the same for populations from different regions, and the influences of gender...article 2011

Martens, M.H. (author)The current study focuses on Change Blindness in a road environment. The purpose of the experiment is to study how the type of change induced affects the strength of Change Blindness and the role of glance duration and attention. Hundred-thirty-one participants watched video films showing six drives around a block filmed from the drivers...article 2011

Bos, J.E. (author)The most cited theory on motion sickness is the conflict theory by Reason and Brand (1975) [1], stating that motion sickness occurs due to a conflict between the senses and stored patterns of motion. In addition, there seems to be evidence for another theory stating that postural instability is a necessary and sufficient condition preceding...article 2011

van Erp, J.B.F. (author), Lotte, F. (author), Tangermann, M. (author)Brain-computer interaction has already moved from assistive care to applications such as gaming. Improvements in usability, hardware, signal processing, and system integration should yield applications in other nonmedical areas.article 2012

Jansen, S.E.M. (author), Toet, A. (author), Werkhoven, P.J. (author)In this study, the authors investigated how restriction of the vertical viewing angle influences obstacle-crossing behavior. Twelve participants stepped over obstacles of different dimensions while wearing visual-field-restricting goggles. Using full-body motion capture, several kinematic measures were extracted and analyzed. Results indicate...article 2011

Arendsen, J. (author), van Doorn, A.J. (author), de Riddera, H. (author), TNO Defensie en Veiligheid (author)This study contains the results of an experiment in which signers were asked to judge the acceptability of a set of sign manipulations. signs were recorded with variations in different categories. In the temporal and spatial dimension. participants varied much in tolerance. I.e. in the percentage of movies they judged to be acceptable. But their...article 2010

Toet, A. (author), Hogervorst, M.A. (author)We present an overview of our recent progress and the current state-of-the-art techniques of color image fusion for night vision applications. Inspired by previously developed color opponent fusing schemes, we initially developed a simple pixel-based false color-mapping scheme that yielded fused false color images with large color contrast and...article 2012

Toet, A. (author), Houtkamp, J.M. (author), van der Meulen, R. (author)We investigated whether manipulation of visual and auditory depth and speed cues can affect a user’s sense of risk for a low-cost nonimmersive virtual environment (VE) representing a highway environment with traffic incidents. The VE is currently used in an examination program to assess procedural knowledge of highway patrol officers. In its...article 2013

Nooij, S.A.E. (author), Vanspauwen, R. (author), Bos, J.E. (author), Wuyts, F.L. (author)During the first days of spaceflight, about 50-70% of the astronauts experience symptoms of Space Motion Sickness (SMS). It has been proposed that an asymmetry between the left and right otolith organs contributes to an astronaut's individual susceptibility. A recently developed test to measure unilateral utricular function enabled us to re...article 2011

(author)For surveillance and rescue operations, human navigation and situation awareness should be well-supported. However, proper testing of new and innovative mobile support is hard for such operations. Evaluations in field settings are expensive, difficult to control, potentially dangerous, and may sometimes be impossible to execute. Using a virtual...article 2011

Khalid, H. (author), Turan, O. (author), Bos, J.E. (author), Incecik, A. (author)Subjective-vertical conflict theory (Bles et al., 1998) postulates that all motion sickness provoking situations are characterized by a condition in which the vertical (gravity) sensed by the visual, vestibular and non-vestibular proprioceptors are at variance with the subjective (expected) vertical. SV-conflict models have successfully been...article 2011

Hogervorst, M.A. (author), Toet, A. (author), Bijl, P. (author)We investigate how human visual search performance with field of view (FOV) restrictions depends on scan speed, zoom factor, target location, and conspicuity. First, observers search a FOV that moves at a constant speed along a predefined path over a visual search scene (the field of regard, or FOR), and we measure the effects of scan speed,...article 2013

van Erp, J.B.F. (author), Philippi, T.G. (author), Werkhoven, P. (author)In the illusory flash paradigm, a single flash may be experienced as two flashes when accompanied by two beeps or taps, and two flashes may be experienced as a single flash when accompanied by one beep or tap. The classic paradigm restricts responses to '1' and '2' (2-AFC), ignoring possible qualitative differences between real and illusory...article 2013

Brouwer, A.M. (author), van Erp, J.B.F. (author)How can you tell whether someone working or gaming is mentally taxed too high or too low? In collaboration with Noldus IT (Wageningen) and the FC Donders Institute (Nijmegen), TNO designed and conducted an experiment to measure mental load through brain signals. 35 participants performed a computer task that varied in difficulty. Our classifiers...article 2012
