Short answer

Designers must create smart environments that are not only functional but also adaptable to the diverse sensory processing needs of all users, especially neurodivergent individuals.

Field: User-Centred Design
Source: Building and Environment (2024)
Method: Comparative experimental study
Sample: 27 participants (14 with ADHD, 13 without ADHD)
Evidence: Strong effect

Individuals with ADHD exhibit different neuro-responses to environmental discomfort compared to neurotypical individuals, necessitating adaptive design strategies in smart buildings. This user-centred design research insight is drawn from a 2024 study published in Building and Environment. Using Comparative experimental study with 27 participants (14 with ADHD, 13 without ADHD), researchers explored how this design variable affects real-world outcomes. The key design takeaway: Designers must create smart environments that are not only functional but also adaptable to the diverse sensory processing needs of all users, especially neurodivergent individuals.

Neurodivergent Sensory Processing Demands Adaptive Smart Building Design

Individuals with ADHD exhibit different neuro-responses to environmental discomfort compared to neurotypical individuals, necessitating adaptive design strategies in smart buildings.

Building and Environment · 2024

Key Findings

01Participants without ADHD showed significant EEG activation of a defense system in response to environmental discomfort.
02This defense system activation was notably absent, slow, or weak in participants with ADHD.
03Differences in neuro-responses highlight varied sensitivities to visual and acoustic stimuli.

Application

Design takeaway

Designers must create smart environments that are not only functional but also adaptable to the diverse sensory processing needs of all users, especially neurodivergent individuals.

How to apply

When designing spaces, consider implementing dynamic lighting and sound systems that allow users to adjust settings based on their comfort levels, or that can automatically adapt based on detected user states.

Project actions

01When researching user needs, actively seek out and include perspectives from neurodivergent individuals.
02Consider how sensory elements (light, sound, texture) might impact different user groups.
03Explore the use of adaptive technologies in your design proposals.

Method & Evidence

AimTo investigate how visual and acoustic environmental conditions differentially impact individuals with and without ADHD, as measured by EEG, task performance, and self-reported comfort.

MethodComparative experimental study

ProcedureParticipants (with and without ADHD) performed an on-screen activity in six controlled laboratory conditions featuring modified lighting and sound. EEG, eye-tracking, health monitoring, task performance, and self-reported comfort data were collected.

Sample27 participants (14 with ADHD, 13 without ADHD)

ContextSmart building design, interior environments, neurodiversity

Variables

IV["Environmental conditions (lighting, sound)","Participant group (with ADHD, without ADHD)"]

DV["EEG brain activity (defense system activation)","Task performance","Self-reported comfort levels"]

CV["On-screen activity performed","Laboratory setting","Randomized order of conditions"]

Strengths & Limitations

Strengths

+Utilized objective biosignal measurement (EEG) alongside subjective reports and performance data.
+Directly compared neurodivergent and neurotypical groups on specific environmental stimuli.

Limitations

It can be challenging to recruit a diverse sample size, and accurately measuring subjective comfort can be difficult.

Reliability & validity

The use of EEG provides objective physiological data, enhancing the study's reliability. However, the subjective nature of comfort ratings and the controlled laboratory setting may impact external validity.

Think critically

How might the observed differences in neuro-responses influence the design of interactive interfaces or public spaces beyond just lighting and acoustics?

Design Principles

"Design for sensory adaptability and personalization to ensure inclusivity."

Understanding these distinct sensory processing differences is crucial for creating inclusive smart environments. Designers must move beyond one-size-fits-all solutions to accommodate a wider range of user needs, particularly for neurodivergent populations.

What This Means for Your Design

People with ADHD react differently to annoying lights and sounds than people without ADHD. This means buildings need to be able to change their lights and sounds to make everyone comfortable.

How to use in your project

1.Reference this study when discussing the importance of user research for diverse populations, particularly in the context of environmental design.
2.Use the findings to justify the need for adaptive features in your design solution.

Paragraph starter

This research highlights the critical need for adaptive design in smart environments, as individuals with and without ADHD exhibit distinct neuro-physiological responses to visual and acoustic stimuli. The study's findings underscore that a one-size-fits-all approach to environmental design can inadvertently exclude neurodivergent users, necessitating the development of flexible and personalized systems to cater to a broader spectrum of sensory experiences.
