Haptic Stovetops
Where Touch Meets Taste is an accessibility focused interaction design project that reintroduces tactile heat feedback to modern stovetops through vibration. By translating heat levels into vibration intensity, the system allows users to confidently adjust stove temperature without relying on visual controls, supporting visually impaired cooks while improving usability for all.
The Problem
Modern stovetops rely heavily on smooth digital interfaces and visual indicators. While visually clean, these designs remove tactile cues that many users depend on. For visually impaired cooks, this creates uncertainty around heat control, increases anxiety, and limits independence in the kitchen.
The Concept
This project introduces a haptic heat control system embedded directly into a stove knob. As the knob is turned, vibration intensity increases or decreases to match the heat level. Low heat produces a gentle vibration while high heat produces a stronger tactile response, creating a physical scale users can feel and learn over time.

Prototype and Testing
A functional prototype was built by embedding a vibration motor into a modified stove knob. Multiple vibration patterns were tested to evaluate how clearly users could identify heat levels using touch alone.
Testing focused on accuracy of heat identification, speed of adjustment, and user reported confidence while interacting with the system.
Results
Users reliably distinguished between low and high heat levels through vibration. Gradual changes in vibration intensity felt more intuitive than abrupt shifts. Visually impaired participants reported increased confidence and reduced anxiety compared to visual only cooktops. Sighted users also found the tactile feedback intuitive and helpful.
The hypothesis was supported. Tactile vibration enabled safer and more confident heat control without visual reliance.
Key Insights
Touch is an effective and underused communication channelVibration provides immediate and trustworthy feedbackIntegrated tactile systems feel more dignified than add on toolsUniversal design benefits both visually impaired and sighted users
Impact and Next Steps
Where Touch Meets Taste demonstrates how small interaction changes can significantly improve accessibility and independence. Future work includes refining vibration gradients, expanding user testing, and exploring integration into commercial cooktop designs.
Why This Matters
This project reframes accessibility as a core design feature rather than an afterthought, showing how inclusive interaction design can create safer, more intuitive everyday tools for everyone.
