Sound symbolism refers to the non-arbitrary mappings that exist between phonetic properties of speech sounds and their meaning. Despite there being an extensive literature on topic, acoustic features psychological mechanisms give rise sound are not, as yet, altogether clear. The present study was designed investigate whether different sets cues predict size shape symbolism, respectively. In two experiments, participants judged a given consonant-vowel large or small, round angular, using...

The human emotional reactions to stimuli delivered by different sensory modalities is a topic of interest for many disciplines, from Human-Computer-Interaction cognitive sciences. Different databases eliciting reaction are available, tested on high number participants. Interestingly, within one database always the same type. In other words, date, no data was obtained and compared distinct types emotion-eliciting participant. This makes it difficult use experiment, limiting complexity...

The human sense of smell is powerful. However, the way we use as an interaction modality in human–computer (HCI) limited. We lack a common reference point to guide designers’ choices when using smell. Here, map out olfactory design space provide designers with such guidance. identified four key features: (i) chemical, (ii) emotional, (iii) spatial, and (iv) temporal. Each feature defines building block for smell-based grounded review relevant scientific literature. then demonstrate...

For decades, the use of vision and audition for interaction dominated field human-computer (HCI), despite fact that nature has provided many more senses perceiving interacting with world. Recently, HCI researchers have started trying to capitalize on touch, taste, smell when designing interactive tasks, especially in gaming, multimedia, art environments. Here, authors provide a snapshot their research into smell, carried out at Sussex Computer Human Interaction (SCHI) Lab University Brighton, UK.

Driving is a task that often affected by emotions. The effect of emotions on driving has been extensively studied. Anger an emotion dominates in such investigations. Despite the knowledge strong links between scents and emotions, few studies have explored olfactory stimulation context driving. Such outcome provides HCI practitioners very little how to design for using car. We carried out three select different valence arousal levels (i.e. rose, peppermint, civet) anger eliciting stimuli...

Smell is a powerful tool for conveying and recalling information without requiring visual attention. Previous work identified, however, some challenges caused by user's unfamiliarity with this modality complexity in the scent delivery. We are now able to overcome these challenges, introducing training approach familiarise scent-meaning associations (urgency of message, sender identity) using controllable device scent-delivery. Here we re-validate effectiveness smell as notification present...

Taste perception is influenced by sensory information not only about the food itself but also external environment where tasted. Prior studies have shown that both visual attributes of (e.g., light colour, location) and shape associated to plates, cutlery) can influence people's taste expectations. However, previous are typically based on non-edible shapes usually as 2D images or presented 3D tangible objects aimed be perceived subjects' hand. Therefore, effect mouthfeel differently shaped...

Abstract Background Major depressive disorder (MDD) is a heterogeneous psychiatric condition associated with high risk of mortality considering both rates suicide [1] and severe comorbid cardiometabolic dysfunctions [2]. Environmental variables such as adverse childhood experiences (ACEs) can furtherly interact the disorder’ s prognosis [3-4]. However, not all MDD patients exhibit same illness trajectories, thus leading to inconsistent findings between clinical outcomes underlying...

While there is an increased appreciation for integrating haptic feedback with audio-visual content, still a lack of understanding how to quantify the added value touch user's experience (UX) multimedia content. Here we focus on three main concepts measure this value: UX, emotions, and expectations. We present case study measuring standardized set content (i.e., short video clips), comparing two stimulation modalities mid-air vs. vibro-tactile stimuli). Our findings demonstrate that UX...

The sense of smell is well known to provide very vivid experiences and mediate a strong activation crossmodal semantic representations. Despite growing number olfactory HCI prototypes, there have been only few attempts study the as an interaction modality. Here, we focus on exploration olfaction for in-car design by establishing mapping between three different driving-related messages ("Slow down", "Fill gas", "Passing point interest") four scents (lemon, lavender, peppermint, rose). results...

When designing olfactory interfaces, HCI researchers and practitioners have to carefully consider a number of issues related the scent delivery, detection, lingering. These are just few problems deal with. We present OSpace - an approach for designing, building, exploring interaction space. Our paper is first explore in detail not only scent-delivery parameters but also air extraction issues. conducted user study demonstrate how detection/lingering times can be acquired under different...

Cars provide drivers with task-related information (e.g. "Fill gas") mainly using visual and auditory stimuli. However, those stimuli may distract or overwhelm the driver, causing unnecessary stress. Here, we propose olfactory stimulation as a novel feedback modality to support perception of notifications, reducing demand driver. Based on previous research, explore application scents lavender, peppermint, lemon convey three driving-relevant messages (i.e. "Slow down", "Short inter-vehicle...

Overreliance in technology is safety-critical and it assumed that this could have been a main cause of severe accidents with automated vehicles. To ease the complex task permanently monitoring vehicle behavior driving environment, researchers proposed to implement reliability/uncertainty displays. Such displays allow estimate whether or not an upcoming intervention likely. However, presenting uncertainty just adds more visual workload on drivers, who might also be engaged secondary tasks. We...

There is increasing interest in multisensory experiences HCI. However, little research considers how sensory modalities interact with each other and this may impact interactive experiences. We investigate children associate emotions scents 3D shapes. 14 participants (10-17yrs) completed crossmodal association tasks to attribute emotional characteristics variants of the "Bouba/Kiki" stimuli, presented as tangible models, conjunction lemon vanilla scents. Our findings support pre-existing...

Eating is one of the most multisensory experiences in everyday life. All our five senses (i.e. taste, smell, vision, hearing and touch) are involved, even if we not aware it. However, while integration has been well studied psychology, there a single platform for testing systematically effects different stimuli. This lack results unresolved design challenges taste-based immersive experiences. Here, present LeviSense: first system designed gustatory based on levitated food. Our enables...

Abstract In the last few years, psychologists and neuroscientists have increasingly investigated presence of multisensory interactions in people's perceptions food beverage. For example, results a recent questionnaire‐based study showed that wine is believed to be more expensive better quality when contained heavier bottle. However, it remains unclear whether various foods or liquids share similar associations mind consumer. laboratory study, we between taste mineral water weight plastic cup...
