Role: CTO + CDO
Overview
Safe Vibe is a wearable festival wristband that uses radio frequency communication to help users locate missing companions without relying on mobile networks or smartphones. The device functions reliably in high-density event environments, while also introducing new forms of interaction through ambient light and vibration, and can be designed as a potential piece of event merchandise, integrating safety into the broader festival experience.
Problem / Purpose
When crowds are dense, phone signals are unreliable, batteries run low, and people can easily become separated from their group. Safe Vibe was developed as a standalone system that could operate independently, while remaining intuitive, wearable, and socially integrated into the event environment.
Process
I worked across both technical development and product design. I contributed to designing the interaction system, where users could trigger signals through button input, activating RF communication between devices. This was translated into proximity-based feedback using LEDs and vibration, allowing users to navigate toward each other through increasing signal intensity.
In parallel, I led the 3D design of the wristband in Rhino, focusing on functionality, wearability, and aesthetic integration so that the device could function effectively without feeling like a medical or surveillance tool. A crucial part of my contribution was making sure the technical components and physical design supported each other as a cohesive system, and is visually appropriate for festival use.
Our business model follows a B2B approach, wherein we produce wristbands in bulk at a cost-effective price. These wristbands are then rented out to festival organisers, who, in turn, offer them as an enticing additional service to event attendees alongside their tickets. This ensures affordability for the attendees while generating extra revenue for the events. Additionally, we explore merchandising options for the wristbands.
Outcome
The final concept demonstrates how wearable technology and sensor systems can be applied in real-world environments, combining functionality with experiential design. It highlights my ability to design integrated hardware interactions and visualise design into a considered, user-centred product.
