How does HoloTouch® technology Work?
Here’s a simple explanation of how HoloTouch® human-machine (“HMI”) technology works:
HMIs using HoloTouch technology allow people to intuitively enter commands and data into a wide range of electronic equipment by simply passing a finger through holographic images of what would otherwise be buttons or keys of keypads or keyboards, floating in the air at a convenient location – intuitive, touchless controls. An infrared sensor detects intrusion of a finger into those images, identifies which command has been selected and transmits that selection to the equipment’s internal software, in much the same way as pressing a button on any ordinary keyboard. Interfaces customized with HoloTouch technology provide output to USB, serial and other PC ports as well as relay output to other devices such as PLCs. Increasingly sophisticated sensors, some capable of mapping multiple points on planes in space, combined with more creative hologram recording techniques, provide the simple and inexpensive basis for multiple “button” touchless, holographic HMIs such as the functional equivalents of keypads or touch screens but with no moving parts and nothing to actually touch in using them.
