Missing wallets and hidden items may one day be a thing of the past.
headset. RFID locators, which adhere to products like stickers and reflect signals back to antennas, generally rely on multiple antennas spaced apart from one another. In this case, the team needed to optimize a single antenna to handle a high enough bandwidth for the tags. Not only that, but the antenna couldn’t obscure any portion of the Hololens’ other visual tools and sensors.
After extensive testing X-AR’s creators were able to guide users with nearly 99 percent accuracy to items scattered throughout a warehouse testing environment. When those products were hidden within boxes, the X-AR still even boasted an almost 92 percent accuracy rate.
In future iterations, the team hopes to expand its sensing capabilities to incorporate WiFi, mmWaves, or terahertz waves. Right now, researchers say X-AR also only works within three meters of an object, so expanding its radius will be key for any future public deployment, alongside coordination abilities between multiple headsets.Andrew Paul is Popular Science's staff writer covering tech news.
