Do Multisensory Stimuli Benefit the Virtual Reality Experience? A Systematic Review
IEEE Transactions on Visualization and Computer Graphics
|August 4, 2020
Summary
Multisensory virtual reality (VR) enhances experiences beyond sight and sound. Haptic feedback is common, but smell and taste offer untapped potential for more immersive VR applications.
Area of Science:
- Computer Science
- Human-Computer Interaction
- Sensory Perception
Background:
- Most virtual reality (VR) applications primarily use audiovisual stimuli.
- The potential of VR can be significantly increased by incorporating additional sensory cues.
- Exploring multisensory stimuli beyond audiovisual is crucial for advancing VR technology.
Purpose of the Study:
- To systematically review literature on multisensory VR.
- To assess the impact of haptic, olfactory, and taste cues on the VR experience.
- To identify common stimuli, VR setups, and application fields in multisensory VR research.
Main Methods:
- Systematic literature review of 105 eligible studies.
- Analysis of studies focusing on multisensory VR incorporating haptic, olfactory, and taste stimuli.
- Categorization of VR setups (immersive, non-immersive, semi-immersive) and application fields.
Main Results:
- 84.8% of studies reported a positive impact of multisensory VR experiences.
- Haptic stimuli were the most frequently used (86.6%) in multisensory VR systems.
- Non-immersive and immersive VR setups were more prevalent than semi-immersive ones.
Conclusions:
- Multisensory VR, particularly with haptic feedback, significantly enhances user experience.
- Olfactory and gustatory (smell and taste) stimuli are underexplored but hold substantial potential for VR.
- Further research is needed to simplify the synthesis and delivery of smell and taste stimuli for broader VR integration.

The somatosensory system is the central and peripheral nervous system component that senses and processes touch, pressure, pain, temperature, and body position or proprioception. The process of sensation takes place at three levels:
The receptor level:
The receptor level is the first stage of sensation. It involves the detection of a stimulus by specialized sensory receptors. The stimulus must arrive within the receptor's receptive field. Next, the receptor converts the energy of the...

Sensation typically is the process by which the sensory receptors and sense organs detect stimuli from the internal and external environment and transmit this information to the central nervous system for processing.
General senses refer to the broad category of sensory information detected by receptors in the body and can be further grouped into somatic and visceral senses. Somatic sensations include touch, pressure, temperature, and pain and are essential for navigating our environment and...
