About the Interviewee: Doug McPheters is the inventor of widely patented touchless, holographic HoloTouch® HMI technology and manager of its commercialization at HoloTouch, Inc. ( ).  HoloTouch technology lets people operate all types of electronics by simply passing a finger through holographic images of what would otherwise be keys or buttons, floating freely in the air – no moving parts to fail under use or abuse, no hygiene issues (nothing to actually touch) and no repetitive stress problems.  He can be reached at 203.588.9808 or

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.
