We introduce inter-technology backscatter (Interscatter), a novel approach that transforms wireless transmissions from one technology to another, on the air. Specifically, we show for the first time that Bluetooth transmissions can be used to create Wi-Fi and ZigBee-compatible signals using backscatter communication. Since Bluetooth, Wi-Fi and ZigBee radios are widely   Read More ...

FingerIO is a novel fine-grained finger tracking solution that transforms any space around off-the-shelf smartphones or smartwatches into an interactive surfaces. FingerIO does not require instrumenting the finger with sensors and works even in the presence of occlusions between the finger and the device. We achieve this by transforming the   Read More ...

We introduce Passive Wi-Fi that demonstrates for the first time that one can generate 802.11b transmissions using backscatter communication, while consuming 3 – 4 orders of magnitude lower power than existing Wi-Fi chipsets. Passive Wi-Fi transmissions can be decoded on any Wi-Fi device including routers, mobile phones and tablets. Building   Read More ...

Quoting the article “Now researchers at the University of Washington have found a way to eliminate the airtime and the hassle—by using the human body as a conduit for passing security codes from one device to another. By holding a smartphone in one hand, for example, and touching a doorknob   Read More ...

We show for the first time that commodity devices can be used to generate wireless data transmissions that are confined to the human body. Specifically, we show that commodity input devices such as fingerprint sensors and touchpads can be used to transmit information to only wireless receivers that are in   Read More ...

  The article says Shyam Gollakota uncovered a way to create Wi-Fi signals without radio transistors. And here’s the real payoff: These “passive Wi-Fi” devices use 10,000 times less power than a typical Wi-Fi chip, and 1,000 times less power than the most efficient Bluetooth, thereby significantly reducing the need   Read More ...
