Wi-Fi strength revealed in physical space

Posted to Data Art  |  Tags:  |  Nathan Yau

Digital Ethereal is a project that explores wireless, making what’s typically invisible visible and tangible. In the piece above, a handheld sensor is used to detect the strength of Wi-Fi signal from a personal hotspot. A person waves the sensor around the area, and long-exposure photography captures the patterns.

Reminds me of the Immaterials project from a while back, which used a light stick to represent signal strength rather than a signal light.
