For millions of people with mobility or speech limitations, even the simplest tasks - switching on a light, ringing a bell, or calling for help can become frustrating challenges. Gesture Powered Signage changes that.
It’s not just another wearable.It’s a gesture-driven control and communication system designed for patients, the elderly, and anyone who struggles with traditional switches or touchscreens.
With just a twist or swipe of the hand, users can control appliances, send alerts, or even make a phone call — all without touching a button, using their voice, or relying on the internet.
During hospital visits, I noticed how some patients couldn’t even press a call button to ask for help. That inspired me to design a device that could work with simple, natural movements, giving them back independence and peace of mind.
The goal was simple: make control accessible anywhere, anytime without complicated setup or extra hardware.
