Overview

EXPLORER was designed to address real-world challenges users face when navigating dark environments while keeping their hands free. Through early concept exploration and user feedback, our team identified the need for a wearable solution that balanced safety, comfort, and everyday usability.

Unlike traditional headlamps or handheld flashlights, EXPLORER distributes weight evenly across the head in a familiar hat form, making it more comfortable for extended use. The system combines front-facing adjustable lighting, tactile physical buttons, a mobile companion app, solar-assisted charging, a built-in camera, and SOS emergency functionality into a single integrated wearable.

The design prioritizes accessibility and intuitive interaction, ensuring it can be used in outdoor work, walking at night, hiking, and emergency scenarios without requiring complex gestures, voice commands, or constant phone interaction.

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 for hands-free use in low-light environments.

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

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

  • Feedback gathered through early concept walkthroughs

Key insights

How feedback was collected

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

  • Repeated questions about:

    • Battery life

    • Charging method

    • Water resistance

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

  • Front-facing camera validated for safety and work documentation

  • Users requested a visible battery indicator in the 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

  • Water resistance prioritized for future iterations

Final Design Concept

The final design integrates adjustable front-facing lighting, tactile control buttons, solar charging, a built-in camera, and an SOS safety feature. EXPLORER supports real-world use cases including nighttime walking, outdoor work, camping, and personal safety scenarios.

The final design integrates adjustable front-facing lighting, tactile control buttons, solar charging, a built-in camera, and an SOS safety feature. EXPLORER supports a wide range of use cases including walking at night, outdoor work environments, camping, and personal safety scenarios.

Unlike traditional headlamps or handheld flashlights, EXPLORER distributes weight evenly across the head while maintaining a familiar and stylish appearance. The design reflects a synthesis of safety, functionality, and real-world usability informed directly by user feedback.

Physical Prototypes

To translate our final EXPLORER concept into a tangible form, each team member constructed a physical prototype using everyday materials. While small aesthetic variations exist, all prototypes represent the same core feature set, including front-facing lighting, tactile control buttons, solar charging placement, and camera positioning. These models allowed us to evaluate scale, placement, comfort, and real-world wearability.

Related UI: Mobile App Interface

The EXPLORER mobile app serves as the companion control center for the wearable lighting hat. It allows users to manage lighting, camera, and safety features in real time while keeping their hands free.

Core features include:

  • Live camera feed with recording controls

  • Brightness adjustment

  • Light area / coverage control

  • SOS emergency activation

  • Device status and battery visibility

  • Route and usage history

The interface was designed to be simple, high-contrast, and easy to use in motion, supporting quick interactions during walking, outdoor work, and low-visibility environments. The UI directly mirrors the physical controls on the hat to reduce cognitive load and improve usability.
