Key Findings

  • 01Visual-auditory and visual-olfactory interactive stimuli were more effective than single visual stimuli for visual attention recovery in low-noise environments.
  • 02Visual-auditory-olfactory interactive stimuli optimized spatial perception by masking negative experiences with positive sensory inputs.
  • 03Environments with a high proportion of natural sounds showed the strongest stimuli.
  • 04In the visual-auditory group, systolic blood pressure and heart rate significantly decreased.
  • 05Aromatic olfactory sources (marigolds, boxwood, camphor trees) were more effective in promoting physical and mental relaxation, leading to significant reductions in systolic blood pressure.

Application

Design takeaway

Designers should move beyond purely visual considerations in urban green spaces and actively integrate complementary auditory and olfactory elements to maximize user well-being and restorative potential.

How to apply

When designing or renovating urban parks, consider the strategic placement of fragrant plants, the inclusion of natural water features or bird feeders to enhance soundscapes, and ensure good visual appeal.

Project actions

  • 01When researching user needs, consider how different senses contribute to their experience.
  • 02In your design proposals, clearly articulate how visual, auditory, and olfactory elements work together.
  • 03When testing prototypes, use methods that capture multi-sensory responses, not just visual ones.

Method & Evidence

AimTo investigate the combined effects of visual, auditory, and olfactory stimuli on human perception and psychological recovery within urban microgreen spaces.
MethodExperimental study with sensory group comparisons.
ProcedureParticipants were assigned to groups experiencing single sensory stimuli (visual, auditory, or olfactory), combinations of stimuli, or a control condition. Physiological (blood pressure, heart rate) and psychological (attention, mood) measures were collected using eye-tracking, blood pressure monitors, Semantic Differential scales, and the Profile of Mood State (POMS).
SampleNot explicitly stated, but participants were evenly divided into eight groups.
ContextUrban microgreen spaces (small parks).

Variables

IV["Type of sensory stimuli (single visual, visual-auditory, visual-olfactory, visual-auditory-olfactory, control)","Type of olfactory source (aromatic plants vs. other)","Proportion of natural sounds"]
DV["Visual attention recovery","Psychological perception recovery","Spatial perception quality","Systolic blood pressure","Heart rate","Mood state"]
CV["Ambient noise levels (kept relatively low)","Type of urban microgreen space"]

Strengths & Limitations

Strengths

  • +Employed objective physiological measures (blood pressure, heart rate) alongside subjective scales.
  • +Utilized advanced technology like eye-tracking for attention assessment.
  • +Investigated the complex interplay of multiple sensory modalities.

Limitations

It can be challenging to control all sensory inputs precisely in a real-world setting, and individual sensory sensitivities can vary greatly.

Reliability & validity

The use of multiple measurement tools (eye-tracking, physiological monitors, psychological scales) enhances the validity of the findings. Reliability would depend on the consistency of the stimuli presentation and participant responses across trials.

Think critically

How might the effectiveness of these multi-sensory interventions change in environments with high levels of urban noise or pollution?

Design Principles

"Multi-sensory integration in restorative environments enhances user experience and psychological recovery."

This research highlights the profound impact of multi-sensory design on user experience in urban environments. By understanding how different sensory inputs interact, designers can create more restorative and engaging public spaces that actively contribute to the mental health of city dwellers.

06

What This Means for Your Design

Making parks smell nice and sound natural, along with looking good, helps people feel more relaxed and focused than if they just looked nice.

How to use in your project

  • 1.Reference this study when justifying the inclusion of specific sensory elements in your design, particularly if aiming for restorative qualities.
  • 2.Use the findings to support your design decisions regarding plant selection or soundscape integration.

Quick Cite

Paragraph starter

Research indicates that the integration of visual, auditory, and olfactory stimuli in urban green spaces significantly enhances psychological recovery and spatial perception. Specifically, multi-sensory interactive environments, such as those combining visual elements with natural sounds and aromatic plants, have shown a greater capacity to promote attention recovery and reduce physiological stress markers compared to visually-focused designs alone. This suggests that a holistic, multi-sensory approach is crucial for creating truly restorative urban environments.
