WiSee is a reasearch project at the University of Washington; as described in this paper, it uses standard WiFi hardware to sense the location and movements of people within range of the signal. Using machine-learning, it maps specific interference patterns to specific gestures, so that it knows that -- for example -- you're waving your hand in the air. This gesture-sensing can be used to control various devices in your home:
WiSee is a novel interaction interface that leverages ongoing wireless transmissions in the environment (e.g., WiFi) to enable whole-home sensing and recognition of human gestures. Since wireless signals do not require line-of-sight and can traverse through walls, WiSee can enable whole-home gesture recognition using few wireless sources (e.g., a Wi-Fi router and a few mobile devices in the living room).
WiSee is the first wireless system that can identify gestures in line-of-sight, non-line-of-sight, and through-the-wall scenarios. Unlike other gesture recognition systems like Kinect, Leap Motion or MYO, WiSee requires neither an infrastructure of cameras nor user instrumentation of devices. We implement a proof-of-concept prototype of WiSee and evaluate it in both an office environment and a two-bedroom apartment. Our results show that WiSee can identify and classify a set of nine gestures with an average accuracy of 94%...
WiSee takes advantage of the technology trend of MIMO, the fact that wireless devices today carry multiple antennas (which are primarily used to improve capacity). A WiSee/WiSee-enabled receiver would use these multiple antennas in a different way to focus only on the user in control, thus eliminating interference from other people.
Amsterdam's Bibliotheca Philosophica Hermetica (AKA "The Ritman Library) houses more ths 25,000 occult texts, covering "Hermetics, Rosicrucians, Theosophy, alchemy, mysticism, Gnosis and Western Esotericism, Sufism, Kabbalah, Anthroposophy, Catharism, Freemasonry, Manichaeism, Judaica, the Grail, Esotericism, and comparative religion."
The queue area at the Haunted Mansion at Disneyland features a row of changing portraits wherein paintings everyday scenes are revealed as sinister and haunted (originally the effect was done with crossfading slide-projectors; now it's done with an amazing, crisp electroluminiscent effect).
This is my last day at my desk until Labor Day: tomorrow, we're driving to Burning Man to get our annual dirtrave fix! If you're heading to the playa, here's three places and times you can find me:
The field of data analytics is growing as fast as the internet itself. Self-driving cars, airline pricing, and huge marketing campaigns are all driven by the insights that data scientists can distill out of vast sums of information. Even with the help of powerful software like Python, it’s a highly skilled position. But those skills […]
If you’re marketing on the web, your Google-fu needs to be strong – and up to date. Without a firm grasp on what drives traffic, you’ll never be able to take the wheel. That’s why even if you know where to put your keywords, a little extra effort goes a long way on any marketer’s […]
Want to keep the dentist away? A little tooth care at morning and night isn’t bad, but it won’t keep the stains from smoking or fried foods at bay for long. If you enjoy your food and want to avoid the consequences, an upgrade from that old analog toothbrush can make a huge difference. Among […]
