The Problem

Sleep disorder refers to a group of conditions that affect the ability to sleep well on a regular basis, leading to problems with falling asleep, staying asleep, or feeling rested upon waking. It can be caused by a variety of factors such as medical conditions, lifestyle habits, and environmental factors

What are the potential
consequences of
sleep disorders?

Sleep disorders impair memory, decision-making, and productivity, leading to accidents and reduced well-being. Addressing sleep issues is essential for long-term health and quality of life.

Interview

In conducting a sleep quality and sleep disorder survey with 178 participants, I gained valuable insights into people's needs and identified specific groups that require assistance.

50% of people choose to exercise or change circadian rhythm when they have trouble falling asleep.

58% of people report waking up in the middle of the night.

60% people admit that they occasionally have difficulty falling asleep, and people report that their sleep quality is fair.

Design Goals

Design a calming, user-friendly sleep aid that enhances the overall sleep experience through intuitive interaction and thoughtful integration into users' nightly routines

Market Analysis

I found out…

An opportunity to connect sleep tracking data directly to physical devices, creating a more personalized and responsive sleep experience.

Design Approaches for the methods

To address common sleep issues like insomnia, our design focuses on light, sound, and aromatherapy—three proven, non-invasive methods that support better sleep.

Sound

Creates a calming environment for better rest

Includes white noise and soothing soundscapes

Light

Reduces blue light exposure
Helps regulate circadian rhythms
Supports natural sleep-wake cycles

Aroma

Complements other sensory elements in sleep routines

A popular complementary therapy for sleep disorders

Design Decisions for the forms

Portable Sleep Aids
Compact, hand-held designs offer safe and gentle lighting for users who wake at night, focusing on ergonomics and minimal disruption during movement.

Sunset Simulation Lighting
Lighting concepts mimic the natural dimming of sunset, helping users relax and transition into sleep by supporting their circadian rhythm.

What does the prototype
evaluation show?

After experimenting with various prototype forms, I've made a new discovery: combining a portable light with an aroma diffuser to create an innovative form for the product.

What is this App?

The Cozy Lumen app offers seamless smart home integration, allowing users to control their sleep environment via voice commands, mobile app, or gesture recognition. It provides customizable sleep settings, including white noise, good-night lights, and real-time sleep insights.
