How people mentally represent their body appearance (i.e., body image perception - BIP) does not always match their actual body. BIP distortions can lead to a detriment in physical and emotional health. Recent works in HCI have shown that technology can be used to change people’s BIP through visual, tactile, proprioceptive, and auditory stimulation. This paper investigates, for the first time, the effect of olfactory stimuli, by looking at a possible enhancement of a known auditory effect on… 

The scent of attraction and the smell of success: crossmodal influences on person perception

  • C. Spence

    Cognitive research: principles and implications
  • 2021
Several potential cognitive mechanisms have been put forward to try and explain such crossmodal/multisensory influences, and some of the neural substrates underpinning these effects have now been characterized.

Different armpits under my new nose: olfactory sex but not gender affects implicit measures of embodiment

The results suggest that sex-related body odors influence implicit but not explicit aspects of embodiment and are in line with unique characteristics of olfaction in other aspects of cognition.

Multisensory Experiences: Where the Senses Meet Technology

. Multisensory experiences, that is, experiences that involve more than one of our senses, are part of our everyday life. We often tend to take them for granted, at least when our different senses

SmellControl: The Study of Sense of Agency in Smell

The Sense of Agency (SoA) is crucial in interaction with technology, it refers to the feeling of 'I did that' as opposed to 'the system did that' supporting a feeling of being in control. Research in

Being Short, Sweet, and Sour: Congruent Visuo-Olfactory Stimulation Enhances Illusory Embodiment

Congruent visuo-olfactory cues might enhance illusory self-identification with an arbitrary object when presented with the smell of a grapefruit in synchrony with the squeezing, and individuals self-identified stronger with the fruit than when they smelled strawberry.

Multisensory Integration as per Technological Advances: A Review

The scope and challenges of new technology in the study of multisensory integration in a world that is increasingly characterized as a fusion of physical and digital/virtual events are examined.

Rethinking the Senses: A Workshop on Multisensory Embodied Experiences and Disability Interactions

The aim is to better understand how the senses can be re-think the senses in technology design for disability interactions and the dynamic self, constructed through continuously changing sensing capabilities either because of changing ability or because of the empowering technology.


An olfactory design space is mapped out to provide designers with a common reference point to guide designers’ choices when using smell and how identifying four key design features facilitates a healthy growth of this research domain and contributes to an intermediate-level knowledge space.

SMELL SPACE: Mapping out the Olfactory Design Space for Novel Interactions

An olfactory design space is mapped out to provide designers with guidance to guide designers’ choices when using smell and how identifying four key design features facilitates a healthy growth of this research domain and contributes to an intermediate-level knowledge space.

On Eliciting a Sense of Self when Integrating with Computers

While some Human-Computer Integration (HInt) systems have successfully demonstrated that humans and technology can be physically and functionally integrated, we find that these integrations are not



As Light as You Aspire to Be: Changing Body Perception with Sound to Support Physical Activity

The results confirm that the effects of sound in body-perception occur even in physically demanding situations and through ubiquitous wearable devices and show that the effect of sound interacted with participants' body weight and masculinity/femininity aspirations, but not with gender.

Multisensory Stimulation Can Induce an Illusion of Larger Belly Size in Immersive Virtual Reality

The results show that first person perspective of a virtual body that substitutes for the own body in virtual reality, together with synchronous multisensory stimulation can temporarily produce changes in body representation towards the larger belly size.

Cross-modal interactions between olfaction and touch.

The results showed that participants rated fabric swatches as feeling significantly softer when presented with a lemon odor than whenPresent with an animal-like odor, demonstrating that olfactory cues can modulate tactile perception.

First Person Experience of Body Transfer in Virtual Reality

It is shown that a first person perspective of a life-sized virtual human female body that appears to substitute the male subjects' own bodies was sufficient to generate a body transfer illusion, supporting the notion that bottom-up perceptual mechanisms can temporarily override top down knowledge resulting in a radical illusion of transfer of body ownership.

Audio-tactile cues from an object’s fall change estimates of one’s body height

The present study shows that cross-modal recalibration of body-height representations as a function of changes in the distant environment results from a mismatch between the predicted and actual outcome of an action, the ball’s release and impact, which are causally-related but separated in space and time.

A Virtual Reality Full Body Illusion Improves Body Image Disturbance in Anorexia Nervosa

It is concluded that the disturbed experience of body size in AN is flexible and can be changed, even for highly emotional body parts, as well as novel starting points from which new interventions for body image disturbance in AN can be developed.

As Light as your Footsteps: Altering Walking Sounds to Change Perceived Body Weight, Emotional State and Gait

A shoe-based prototype senses a person's footsteps and alters in real-time the frequency spectra of the sound they produce while walking that leads to the perception of having a thinner body and enhances the motivation for physical activity inducing a more dynamic swing and a shorter heel strike.

Can I Recognize My Body's Weight? The Influence of Shape and Texture on the Perception of Self

This research investigated women's sensitivity to changes in their perceived weight by altering the body mass index of the participants' personalized avatars displayed on a large-screen immersive display and found shape and texture had an effect on the reported similarity of the body parts and the whole avatar to the participant's body.
