According to materials recently released online by the Department of Homeland Security, researchers at the Transportation Security Administration have designed virtual reality technology that can effectively pat a person without touching them directly.
The concept technology, known as the “wearable sensor for contactless physical evaluation”, combines touch-free sensors, cameras and tactile feedback pads and virtual reality headsets to “physically simulate” the “feeling” of traditional screening. DHS has patented the device and initially reported 404 media on the technology.
The description of wearable devices states that the technology “can “make the technology that can keep personal privacy during the safety screening process, or safely provide physical awareness to people with visual impairments “may minimize potential harm.”

According to federal agencies, in 2024, TSA screened 904 million passengers. An unknown number of those passengers received the pat, which the agency said was used to determine whether the passenger had concealed prohibited items, such as guns or knives.
In the past, such screenings have been circulating online in the past, with passengers claiming they are affected by invasive, sexual or other improper touching.
Mixable light speed
Sensor systems can use millimeter-wave scanning, light detection and range (LIDAR) or backscattering techniques to reveal hidden items in clothing. A handheld pad device equipped with these sensors will detect the “outline” of the individual to eventually produce a map that guides the user’s hand through tactile feedback.
According to 404 media review of patent documents, the display of sensitive body parts will be restricted to protect privacy.
However, 404 media also spoke with an anonymous, skeptical privacy expert who questioned whether the technology was indeed non-invasive.
“The idea I think is that the person being searched doesn’t feel it, but can TSA officials go all out?” “The officers can feel… maybe it’s more invasive (or inappropriate)? At the same time, 3D renderings of your body were collected.”
Currently, TSA still screens in old-fashioned ways – millimeter wave imaging, through metal detectors and yes, often read pats.
