This invention introduces a groundbreaking way for humans to interact with computers—without touching screens, keyboards, or mice. Today, we rely on tools like keyboards, touchscreens, and voice commands, but these methods often fall short in precision, comfort, or versatility, especially in complex environments like virtual reality or surgery. Many newer systems still require wearables or sensors to be attached to the body, which can be uncomfortable and limit natural movement.
The core innovation here is a contactless interaction system based on tracking a person’s hand, body, or facial movements in 3D space. Using advanced 3D coordinate measurement—like stereo camera vision—the system detects the position, motion, and gestures of the user and converts them into computer commands. It creates virtual keyboards and mice that float in space, allowing users to “type” or “click” in midair. Users can also directly interact with virtual objects on a screen or in 3D environments by moving naturally—no gloves, no headsets, no wires required.
What sets this apart is its ability to replicate full keyboard and mouse functionality and complex interactive tasks without any physical contact. It also supports advanced input types like lip reading, eye movement tracking, and gesture recognition, all within a highly flexible setup.
Benefits include
- More intuitive and natural control
- Touch-free interaction (hygienic and mobile)
- Ideal for VR/AR, medical surgery, flexible screens, and devices with no room for physical interfaces
- Enhanced accessibility for people with disabilities
The broader impact is significant: this technology could transform how we interact with machines in education, gaming, healthcare, mobile computing, and even daily life—making human-computer interaction more seamless, immersive, and inclusive.
