Follow virtual footsteps towards your lost item with X-AR.
Researchers based at the prestigious Massachusetts Institute of Technology (MIT) are working on an augmented reality (AR) headset that uses holograms to guide users to hidden objects. The device can also use a combination of wireless signals and computer vision technology to see if you’ve picked up the specific object you’re looking for.
The X-AR headset features an AR conformal wideband antenna with radio frequency (RF) sensing capabilities. This flexible antenna works in conjunction with the headset’s camera to perform AR-based SAR localization algorithms that can identify RF-tagged objects even when they pass through certain materials such as cardboard boxes and plastic containers. increase.
Here’s how it works: Data captured by the headset’s sensors are used to build her 3D representation of the user’s environment. The antenna then locates the lost object in the environment with sub-foot accuracy and displays a spherical hologram in the real world. The user then navigates towards the object by following a series of virtual footprints.
As mentioned earlier, X-AR can see objects held by the user with over 95% accuracy. When you put on the headset, you will see a selection of RFID tagged objects. Once an object is identified, the headset verifies that the tag is transmitting the correct RF signal to confirm that it has identified the correct object.
“Our overall goal with this project was to build an augmented reality system that would allow us to see things that are unseen—things inside boxes and in corners. , it can bring you into them and allow you to truly see the physical world in a way that was not possible before. Said Fadel Adib is Associate Professor in the Department of Electrical Engineering and Computer Science, paper With an X-AR headset.
Going forward, the team will be experimenting with various other enhancements. This includes WiFi, mmWave technology, terahertz waves, and an improved antenna with a range of over 3 meters. The team also hinted at support for multiple tuned headsets.
“There is nothing like it today, so we had to find a way to build a completely new type of system from start to finish,” added Adib. “Actually, what we came up with is a framework. There are a lot of technical contributions, but this is the blueprint of how we will design his AR headset with his X-ray vision in the future.” It’s also a photograph.”
