TouchPoint Door Release
Glass Pillar Door Switch
Bringing Smart Surface Touch Systems to Automotive
Enhancing the driving experience as well as offering significant modernization and product differentiation
TouchPoint Door Release
UltraSense’s Door Glass Switch revolutionizes vehicle entry by integrating touch and force sensing directly into the glass pillar. After phone authentication, a light indicates where to press, activating a sleek, handle-free design.
Our advanced sensor fusion and algorithms ensure reliable performance, even in harsh conditions, offering a modern and cost-effective solution.
