Researchers at the Transportation Security Administration have created virtual reality technology to conduct pat-downs without physical contact, as described in documents released online by the Department of Homeland Security. This groundbreaking technology, named a “wearable sensor for contactless physical assessment,” combines touchless sensors, cameras, and a haptic feedback pad with a virtual reality headset to replicate the feeling of a conventional screening. DHS has applied for a patent for this device, with initial reports on the technology coming from 404 Media.
A summary of the wearable device emphasizes its capability to reduce harm when interacting with dangerous objects, safeguard privacy during security checks, and offer physical awareness for individuals with visual impairments. In 2024, TSA processed 904 million travelers, per the federal agency’s data. An unspecified portion of these travelers underwent pat-downs, which the agency utilizes to search for concealed prohibited items such as firearms or knives.
These screenings have previously attracted attention, with passengers claiming they experienced invasive, sexual, or otherwise inappropriate touching. The sensor system may employ millimeter wave scanning, LiDAR, or backscatter X-ray technology to identify items concealed by clothing. A handheld padded device equipped with these sensors would outline an individual’s shape, directing the user’s hand through haptic feedback.
404 Media’s analysis of patent documents suggests that the depiction of sensitive body parts will be limited to uphold privacy. Nonetheless, 404 Media also spoke with an anonymous privacy expert who raised concerns about the non-invasive claims of the technology. The expert conveyed doubt, indicating that while the individual being screened may not perceive any sensation, the TSA officer could still perform an invasive search, potentially increasing the inappropriateness.
At present, the TSA continues to utilize conventional screening techniques, including millimeter wave imaging, walk-through metal detectors, and pat-downs.
