The Problem

Users navigating low-light environments often rely on handheld flashlights or traditional headlamps, which can be inconvenient, uncomfortable, or limiting. Frequently require users to sacrifice either mobility, comfort, or ease of use, especially in situations where hands-free interaction is critical.

Many existing products lack intuitive controls, accessibility considerations, and integrated safety features, making them difficult to use in real-world conditions such as outdoor work, nighttime navigation, or emergency scenarios.

As a result, users face increased cognitive and physical strain when trying to maintain visibility while staying safe and mobile.

The Solution

EXPLORER is a wearable lighting system designed to provide hands-free visibility, safety, and intuitive control in low-light environments.

By integrating adjustable front-facing lighting, tactile physical buttons, solar-assisted charging, a built-in camera, and an SOS emergency feature into a familiar hat form, the design balances comfort, functionality, and real-world usability.

The system prioritizes accessibility by minimizing reliance on complex gestures or constant phone interaction, enabling users to navigate environments confidently while maintaining full mobility.

Preliminary Concepts

&

EarlyDesign Exploration

Each team member explored two early concept directions to test different approaches to lighting placement, controls, comfort, and aesthetics. These sketches were shared with potential users for early feedback.

SLEEK

Minimalist wearable lighting band with tactile controls, Bluetooth connectivity, and front-facing LED visibility.

Beam Band

A lightweight smart lighting band designed for targeted, directional visibility with adjustable brightness controls and hands-free functionality for active movement.

Halo

Wraparound head-mounted lighting designed for balanced illumination without blocking field of view.

EXPLORER

A solar-powered smart lighting hat featuring adjustable front LEDs, tactile controls, built-in camera, SOS safety mode, and mobile app connectivity.

Helping Hat

Comfort-first smart lighting hat with intuitive button placement and hands-free everyday usability.

Modular Visor

A customizable smart lighting visor featuring detachable lighting modules and adjustable positioning for flexible visibility based on user activity and environment.

User Feedback on Early Concepts

How feedback was collected

  • 8 users across healthcare, HVAC, project management, digital advertising, and construction

  • Feedback gathered through concept walkthrough sessions

Key insights

  • Users prioritized comfort, tactile controls, and real-world practicality

  • Frequent concerns included:

    • Battery life

    • Charging method

    • Water resistance

  • Strong preference for a hat-based design over band-style concepts

  • Front-facing camera validated for safety and documentation

  • Users requested a visible battery indicator in the mobile app

How this shaped the final design

  • Confirmed hat-based form factor

  • Preserved physical buttons for outdoor and gloved use

  • Retained camera + SOS safety feature

  • Added battery visibility to the mobile interface

  • Prioritized water resistance for future iterations

Final Design Concept

The final EXPLORER design integrates adjustable front-facing lighting, tactile control buttons, solar-assisted charging, a built-in camera, and an SOS safety feature into a cohesive wearable system.

Designed for real-world use, EXPLORER supports activities such as nighttime walking, outdoor work, camping, and emergency scenarios where hands-free visibility is critical.

By embedding functionality into a familiar hat form, the design distributes weight evenly while maintaining comfort and approachability. The final concept reflects a synthesis of user feedback, safety considerations, and intuitive interaction design.

Physical Prototypes

To translate the EXPLORER concept into a tangible form, each team member constructed a physical prototype using accessible materials. While aesthetic variations exist, all prototypes represent the same core feature set, including lighting placement, control interactions, solar charging integration, and camera positioning, enabled evaluation of scale, ergonomics, comfort, and real-world wearability.

Related UI: Mobile App Interface

The EXPLORER mobile app serves as a companion control system for the wearable device, allowing users to manage lighting, camera functionality, and safety features in real time while keeping their hands free.

Core features include:

  • Live camera feed with recording controls

  • Brightness adjustment

  • Light coverage control

  • SOS emergency activation

  • Device status and battery visibility

  • Route and usage history

The interface was designed to be simple, high-contrast, and usable in motion, supporting quick interactions in low-visibility environments. The UI mirrors the physical controls on the device to reduce cognitive load and improve usability.
