The ubiquity of touchscreens has revolutionized the way we interact with digital devices, but the next frontier in human-machine interaction lies in the development of contactless interfaces. Researchers are making significant strides in this field, particularly with contactless user-interactive sensing displays (CUISDs). These innovative displays respond to the proximity of a fingertip or the humidity of a breath, enabling dynamic, touchless interactions that could transform a wide range of industries and applications.
