# Interactive Asia > Interactive Asia builds OptiTUIO, an in-house LiDAR-based interaction layer that turns large flat surfaces — LED walls, projections, screens, walls and floors — into touchless, multi-user interactive experiences. Based in Chiang Mai, Thailand, since 2008, serving creative agencies, event producers, AV integrators, exhibition designers and brands worldwide. OptiTUIO is not a screen, projector or finished experience by itself. It is the interaction layer that detects visitor input and makes large surfaces respond, working with applications that support Windows Touch, TUIO or mouse input. It is designed for large-format public interaction and visitor engagement — not for small high-precision touch input such as tiny buttons, writing or drawing. A working setup combines a suitable surface, a LiDAR sensor, the OptiTUIO software, a Windows system and a compatible application; correct mounting and calibration are required. Interactive Asia offers the technology, custom application development and full custom installations. Pricing is provided on request per project. ## Product - [OptiTUIO](https://www.interactive-asia.com/en/optituio): The LiDAR-based interaction layer for large interactive surfaces such as LED walls, projections, screens, walls and floors.
