Tactile and Haptic Illusions

IEEE Transactions on Haptics, Journal Year: 2011, Volume and Issue: 4(4), P. 273 - 294

Published: Feb. 11, 2011

This paper surveys the research literature on robust tactile and haptic illusions. The illusions are organized into two categories. first category relates to objects their properties, is further differentiated in terms of processing material versus geometric object properties. second space, observer's own body external space. initially described where possible addressed functional properties and/or underlying neural processes. significance these for design displays also discussed. We conclude by briefly considering a number important general themes that have emerged materials surveyed.

Emotional response to color across media

Color Research & Application, Journal Year: 2009, Volume and Issue: 35(1), P. 64 - 77

Published: Nov. 17, 2009

Abstract In this study, the characteristics of emotional responses to color are explored in two empirical studies. particular, relationship between attributes and dimensions—valence, arousal, dominance—is analyzed. To account for cognitive quantity color, 36 stimuli were selected following hue tone categorizations based on CIELAB LCh system. one experiment, colors presented A5‐size glossy paper whereas identical displayed CRT monitors other experiment. both experiments, subjects assessed each stimulus using a Self‐Assessment‐Manikin (SAM), which consists three rows five pictograms illustrating dimensions emotion, respectively. The results provide evidence that patterns affective judgment can be profiled terms emotion (Reliability coefficient, Cronbach's alpha > 0.7). All colors, i.e. hue, Chroma, Lightness, influenced (repeated measurement One‐way ANOVA, P < 0.05), especially, Chroma was always positively correlated with (r 0.60 0.01). Moreover, indicate vary more strongly regard than categories. Comparing SAM ratings systemic explanation has yet found conclude there is media effect colors. Furthermore, process limit as an elicitor discussed. © 2009 Wiley Periodicals, Inc., Col Res Appl, 2010.

About the Influence of Illumination Models on Image Comprehension in Direct Volume Rendering

IEEE Transactions on Visualization and Computer Graphics, Journal Year: 2011, Volume and Issue: 17(12), P. 1922 - 1931

Published: Nov. 4, 2011

In this paper, we present a user study in which have investigated the influence of seven state-of-the-art volumetric illumination models on spatial perception volume rendered images. Within study, compared gradient-based shading with half angle slicing, directional occlusion shading, multidirectional shadow propagation, spherical harmonic lighting as well dynamic ambient occlusion. To evaluate these models, users had to solve three tasks relying correct depth size perception. Our motivation for was find relations between used model, accuracy and elapsed time. an additional task, subjectively judge output tested models. After first reviewing their features, will introduce individual discuss results. We discovered statistically significant differences testing performance techniques. Based findings, analyzed extracted those features are possibly relevant improved comprehension relational task. believe that combination distinctive could pave way novel would be optimized based our findings.

The Combined Effect of Color and Music on Customer Satisfaction in Hotel Bars

Journal of Hospitality Marketing & Management, Journal Year: 2009, Volume and Issue: 19(1), P. 22 - 37

Published: Nov. 6, 2009

The present study explains how ambience is strongly linked to customer satisfaction in hotel bar servicescapes. requirement of matching elements the servicescape needs consumer indicated by Gestalt theory. Data were collected an experimental setting designed examine if a situation will have more positive effect on individual's than non-Gestalt situation; arousal being moderator. Results indicate that individuals with low are satisfied (tranquil) (dynamic) bar. Our findings suggest service providers should adopt novel or unique colors and music fit purpose their atmosphere enhance customers' level because individual then moderate evaluation.

Scents of Place: The Dysplacement of a First Nations Community in Canada

American Anthropologist, Journal Year: 2011, Volume and Issue: 113(4), P. 606 - 618

Published: Nov. 25, 2011

ABSTRACT Here I explore how the experience of place at a First Nations reserve in Ontario, located middle Canada's “Chemical Valley,” is disrupted by extraordinary levels pollution found there. In so doing, give special attention to air and residents’ responses associated odors—that is, sense smell. Focusing on unique feature smell—that it operates primarily through indexicality—I draw C. S. Peirce's semiotic framework highlight ways which perception odors entails embodiment perceived substance, thus connecting self surroundings profound transformative ways. Ultimately, argue that local smellscape, while having reinforced positive emplacement past, now, because constant presence toxic fumes, instilling residents alienation from ancestral landscape—a condition call “ dysplacement.”

onEEGwaveLAD: A fully automated online EEG wavelet-based learning adaptive denoiser for artefacts identification and mitigation

PLoS ONE, Journal Year: 2025, Volume and Issue: 20(1), P. e0313076 - e0313076

Published: Jan. 28, 2025

Electroencephalographic signals are obtained by amplifying and recording the brain’s spontaneous biological potential using electrodes positioned on scalp. While proven to help find changes in brain activity with a high temporal resolution, such contaminated non-stationary frequent artefacts. A plethora of noise reduction techniques have been developed, achieving remarkable performance. However, they often require multi-channel information additional reference signals, not fully automated, human intervention mostly offline. With popularity Brain-Computer Interfaces application Electroencephalography daily activities other ecological settings, there is an increasing need for robust, online, near real-time denoising techniques, without that automated does supervision nor information. This research contributes body knowledge introducing onEEGwaveLAD , novel, ONline, EEG wavelet-based Learning Adaptive Denoiser pipeline artefact identification reduction. It specific framework can be instantiated various types artefacts paving path towards denoising. As first its kind, it described particular problem blink detection reduction, evaluated across general analysis signal ratio 30 participants.
