wifi sensing

The creator of ESPARGOS, an ESP32-based antenna array from the University of Stuttgart, explains how it senses phase and amplitude of WiFi signals to localize devices and build a WiFi camera. It demos the Python library and project.

CNLohr maps Wi-Fi signal strength at high resolution by moving an ESP8266 on a CNC mill, then visualizes the 3D data in WebGL. The result shows interference patterns in space.

Disney Research presents Touche, a swept frequency capacitive sensing technique that recognizes complex hand and body configurations, and adds touch sensitivity to humans, liquids and everyday objects.

Mobileye co-founder and CTO Amnon Shashua explains what goes into sensing for autonomous driving and whether end-to-end deep learning can work for it. He argues for decomposing the problem.

A clip of Louis CK on Conan riffing that everything is amazing and nobody is happy, about people complaining over airplane wifi and taking modern technology for granted.

Lex Fridman interviews Bryan Johnson, founder of Kernel and previously Braintree, about brain-computer interfaces and Kernel's non-invasive brain monitoring hardware. It covers what the devices can do today and the company's plans.

William Osman describes helping build parts of the MrBeast Squid Game event, including hacking together hundreds of wifi-controlled blood packs in about three weeks. He covers the chaos and near-failures along the way.

A University of Tokyo lab demonstrates a book scanner that flips pages automatically and scans over 250 pages per minute. It uses real-time 3D recognition of the flipped pages and then restores each one to a flat image.

Google ATAP's 2015 introduction to Project Soli, a radar-based sensor on a chip that tracks sub-millimeter hand motions for gesture interaction in small devices.

Linus Tech Tips covers Intel's CES 2024 demos, focusing on Thunderbolt Share and Wi-Fi 7 improvements.

Google ATAP's short 2014 introduction to Project Tango, a mobile device effort to give phones and tablets a human-scale understanding of space and motion. It pitches ideas like indoor navigation and games that interact with your physical space.

Technology Connections explains how touch lamps work and traces them back through patents to the 1950s, far earlier than most people assume.

A Louis C.K. bit from a Conan O'Brien appearance about airplane Wi-Fi and how quickly people feel entitled to new technology.

Mentour Pilot's 56-minute account of the MH370 disappearance and what is now known, including the WSPR radio tracking technique and other sensing methods. It was made ahead of renewed search efforts.

David Sachs of InvenSense explains how gyroscopes, accelerometers and compasses work on their own and together, demonstrated on a modified Android handset. He covers sensor fusion algorithms and why rotation math such as Euler angles matters.

A short clip of Louis CK on Conan riffing that everything is amazing and nobody is happy, about complaining over modern wonders like air travel and wifi. The uploader added a note about the comedian's later misconduct.

Boston Dynamics shows its humanoid robot Atlas picking up and manipulating objects, and altering the obstacle course to reach its goal. The clip demonstrates locomotion, sensing and athletic manipulation.

A short Discovery nature clip from North America showing a red fox listening for field mice under the snow and then diving headfirst to catch them. The narration says the fox uses its hearing and the Earth's magnetic field to aim its jump.
