# Wi-Fi X-Ray Systems The 'Wi-Vi' Lets You See Through Walls with Your Router By Alexander Lam | Published 2013-07-03 | Tech Source: Trend Hunter, https://www.trendhunter.com/trends/wi-vi References: [gizmag](http://www.gizmag.com/wi-vi-see-through-walls/28120/) & [web.mit.edu](http://web.mit.edu/press/2013/new-system-uses-low-power-wi-fi-signal-to-track-moving-humans.html) Using Wi-Fi signals to see through walls, the 'Wi-Vi' system acts to provide the masses with cheap and effective [x-ray vision](https://www.trendhunter.com/trends/mobile-xray-unit). Developed by researchers at the Computer Science and Artificial Intelligence Laboratory in MIT, the system lets anybody see what's happening on the other side of a wall. Wi-Vi uses technology similar to radar and sonar. However, the ingenious system uses Wi-Fi signals instead. The system uses only one receiver to send out or receive Wi-Fi signals. Since signals can penetrate walls, the system can detect movement without a line of sight. Since Wi-Fi signals are so widespread, Wi-Vi has the potential to be used for [gesture-based controls](https://www.trendhunter.com/trends/smart-home-management-system). The system's ability to see beyond walls means that the device can let you control your gadgets no matter where you are in your house. ## Trend Insights (Trend Hunter) - Score: 1.4/10 - Popularity: 8% | Activity: 25% | Freshness: 8% - Audience gender: 50% men, 50% women - Primary generations: Millennial, Gen X - Top markets: North America, Europe ## Categories [Trend Hunter](https://www.trendhunter.com/trends) > [Tech](https://www.trendhunter.com/tech) > [Gadgets](https://www.trendhunter.com/gadgets) ## Key Themes ### Why This Trend Is Growing - **Wi-fi X-ray Vision:** Using Wi-Fi signals to see through walls, this technology offers a cheap and effective alternative to traditional x-ray vision applications. - **Gesture-based Controls:** Wi-Fi signals can be used for gesture-based controls, providing a new and innovative way to interact with technology. - **Remote Gadgets Control:** The ability to see beyond walls using Wi-Fi signals means that this technology can be used to remotely control gadgets from any room in the house. ### Industries Being Reshaped - **Home Security:** Wi-Fi X-Ray Vision can be used for home security applications, detecting movement beyond walls and providing an affordable alternative to traditional security systems. - **Consumer Electronics:** Gesture-based controls using Wi-Fi signals can be applied to various consumer electronics, providing new and innovative ways to interact with technology and enhancing user experience. - **Construction and Architecture:** Wi-Fi X-Ray Vision can be utilized in construction and architecture to detect structural issues beyond walls and improve safety measures. ## Related on Trend Hunter - [Wall-Breaching Drone Trackers](https://www.trendhunter.com/trends/wifi-device-1.md) - [Wi-Fi Elder Care Solutions](https://www.trendhunter.com/trends/origin-wireless-ai.md) - [Wi-Fi-Enabled Senior Care Sensors](https://www.trendhunter.com/trends/wifi-sensing.md) - [AI-Powered WiFi Security Systems](https://www.trendhunter.com/trends/home-security-alarm-system.md) - [Device-Tracking Wifi Routers](https://www.trendhunter.com/trends/radix-be22000-turbo.md) - [Upgraded Wireless Sensing Technologies](https://www.trendhunter.com/trends/wireless-sensing-technology.md) - [Long-Range Wi-Fi Security](https://www.trendhunter.com/trends/edge-camera.md) - [Sculptural Wifi Routers](https://www.trendhunter.com/trends/huawei-x3-pro-wifi.md) - [Indoor Multi-Gigabit Networking Solutions](https://www.trendhunter.com/trends/airvine-wavetunnel.md)
