Creators at the Massachusetts Institute of Technology (MIT) have introduced a new reality called X-AR, which they describe as Augmented Reality with X-Ray Vision.

This x-ray vision differs from the Ironman x-ray vision often depicted with digital twins showing components inside a car, for example. X-AR provides users with an x-ray view of physical objects that are hidden away. In one example they show, a t-shirt is stored away, and X-AR points users to its exact location.

The technology works by placing an antenna on Microsoft’s Mixed Reality Headset, the HoloLens. The antenna is a small tape-on addition to the headset and does not affect the existing sensors and camera. Hidden items are equipped with Radio Frequency Identification (RFID) tags. The headset’s antenna sends a signal, identifying the location of the hidden item. A custom app on the HoloLens then notes where the signal bounces off and guides users to the item’s location. Creators mention that the technology ‘combines wireless sensing with computer vision to enable users to see hidden items.’

This technology operates similarly to how phones and AirTags work. Creators pointed out two significant differences: RFIDs cost almost nothing compared to AirTags, at about two to three cents each, while AirTags cost about thirty dollars apiece. Moreover, RFIDs do not require batteries, so they will always work, and users do not have to worry about battery power.

X-AR finds particular favor in industries such as retail, warehousing, manufacturing, and e-commerce fulfillment, as these sectors benefit from its applications. Researchers and creators at MIT have also pointed out the potential use of this technology to track individuals trapped under a building after an earthquake, as it offers a continuous signal without battery concerns, unlike AirTags. Other use cases include its potential in the medical and healthcare field to track someone’s heart rates and other vital signs.

Like all extended reality technologies, X-AR is still in its early stages, and as we continue to use and explore this technology, more use cases and applications are likely to emerge.
