Presence is a product vision exploring how wearable technology can evolve from reactive health tracking to proactive mental wellbeing. Designed for today's knowledge workers, the concept addresses a growing challenge: recognizing cognitive overload before it impacts performance, decision-making, and long-term wellbeing. By combining AI, biometric sensing, behavioral patterns, and contextual data, Presence helps users better understand their energy, build healthier work habits, and intervene before burnout occurs. Rather than designing a wearable in isolation, I approached Presence as a connected product ecosystem spanning industrial design, software, branding, and digital experiences. The wearable reimagines wellness technology as a refined jewelry-inspired bangle—designed to complement personal style rather than compete with traditional watches. This decision reflects a broader product strategy: creating technology people genuinely want to wear, improving long-term adoption through thoughtful industrial design, accessibility, and inclusive aesthetics. The project encompasses product strategy, hardware design, interaction design, companion mobile experiences, a responsive marketing website, brand identity, and a scalable design system. Every touchpoint was designed to create a cohesive ecosystem that balances user needs, business opportunity, and technical feasibility—demonstrating an end-to-end product design process from vision through execution.
