The affective appraisal of odors is known to depend on their intensity (I), familiarity (F), detection threshold (T), and on the baseline affective state of the observer. However, the exact nature of these relations is still largely unknown. We therefore performed an observer experiment in which participants (N = 52) smelled 40 different odors ...

Introduction: he main purpose of this study was to investigate the overall relation between the mean (at the nomothetic or group level) subjective valence and arousal ratings for odors. Although well established in other sensory modalities (e.g., visual, auditory, gustatory, tactile), this relation has not previously been investigated for odors...

We recently introduced the EmojiGrid as an intuitive graphical self-report tool to measure food­evoked valence and arousal. The EmojiGrid is a Cartesian grid, labeled with facial icons (emoji) expressing different degrees of valence and arousal. The lack of verbal labels makes it a valuable, language-independent tool for cross-cultural...

Social touch forms an important aspect of the human non-verbal communication repertoire, but is often overlooked in human–robot interaction. In this study, we investigated whether robot-initiated touches can induce physiological, emotional, and behavioral responses similar to those reported for human touches. Thirty-nine participants were...

Electronic travel aids (ETAs) can potentially increase the safety and comfort of blind users by detecting and displaying obstacles outside the range of the white cane. In a series of experiments, we aim to balance the amount of information displayed and the comprehensibility of the information taking into account the risk of information overload...

In order to advance the understanding of affective touch perceptions, and in particular to inform the design of physical human-robot interactions, an online video study was conducted in which observed stroking touches were assessed on perceived pleasantness. Touches were applied at different velocities and either with a human hand, a robot hand,...

Gentle stroking touches are rated most pleasant when applied at a velocity of between 1–10 cm/s. Such touches are considered highly relevant in social interactions. Here, we investigate whether stroking sensations generated by a vibrotactile array can produce similar pleasantness responses, with the ultimate goal of using this type of haptic...

The central question of this Frontiers Research Topic is: What can we learn from brain and other physiological signals about an individual's cognitive and affective state and how can we use this information? This question reflects three important issues which are addressed by the 22 articles in this volume: (1) the combination of central and...

Previous research has shown that odorants consistently evoke associations with textures and their tactile properties like smoothness and roughness. Also, it has been observed that olfaction can modulate tactile perception. We therefore hypothesized that tactile roughness perception may be biased towards the somatosensory connotation of an...

Touch is our primary non-verbal communication channel for conveying intimate emotions and as such essential for our physical and emotional wellbeing. In our digital age, human social interaction is often mediated. However, even though there is increasing evidence that mediated touch affords affective communication, current communication systems ...

Tactile displays promise to improve the information-processing capacity of operators, especially when used in conjunction with visual and auditory displays. In this article, we describe current applications and future directions in tactile cuing. © 2015 by Human Factors and Ergonomics Society. All rights reserved.

Although Tangible User Interfaces are considered an intuitive means of human-computer interaction, they oftentimes lack the option to provide active feedback. We developed ‘Sensators’: generic shaped active tangibles to be used on a multi-touch table. Sensators can represent digital information by means of ‘Sensicons’: multimodal messages...

Brain Computer Interfaces (BCIs) rely on the user's brain activity to control equipment or computer devices. Many BCIs are based on imagined movement (called active BCIs) or the fact that brain patterns differ in reaction to relevant or attended stimuli in comparison to irrelevant or unattended stimuli (called reactive BCIs). Traditionally BCIs...

It has been shown that multisensory presentation can improve perception, attention, and object memory compared with unisensory presentation. Consequently, we expect that multisensory presentation of landmarks can improve spatial memory and navigation. In this study we tested the effect of visual, auditory and combined landmark presentations in...

We tested how non-experts judge point probability for seven different visual representations of uncertainty, using a case from an unfamiliar domain. Participants (n = 140) rated the probability that the boundary between two earth layers passed through a given point, for seven different visualizations of the positional uncertainty of the boundary...

Pairing two brief auditory beeps with a single flash can evoke the percept of a second, illusory, flash. Investigations of the underlying neural mechanisms are limited to post-stimulus effects of this sound-induced illusory flash. We investigated whether touch modulates the visual evoked potential in a similar vein, and also looked at pre...

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...

Several interaction techniques have been proposed to enable transfer of information between different displays in heterogeneous multi-display environments. However, it is not clear whether subjective user preference for these different techniques depends on the nature of the displays between which information is transferred. We explore...

This chapter discusses mechanisms of multimodal perception in the context of multimodal simulators and virtual worlds. We review some notable findings from psychophysical experiments with a focus on what we call touch-inclusive multimodal perception—that is, the sensory integration of the tactile system with other sensory systems such as vision...

Abstract In this chapter we discuss Brain-Computer Interfaces (BCIs) as navigation devices from a Human Factors point of view. We argue that navigation is more than only steering a car or a wheelchair. It involves three levels: planning, steering and control, linked to cognition, perception and sensation, respectively. We structure the existing...
