2003-04-25 [missed the first couple of minutes of this] printable organic electronics barcodes that could tell you when eggs have spoiled, etc. The key to all of this is RFIDs: bits of passive silicon that store a string of numbers. The radio reader hits the silicon which answers with its data -- so the reader is where it gets it power from. [so could the radio reader drive a tiny amount of power through some logic and do computation, then store something? now *that's* nanotech. Each time you read it, something iterates and stores it back in permanent memory, *inside* the RFID itself. non-continuous computation] RFIDs are useful, and being used, but they need to be a lot cheaper, 0.5c each. these guys http://www-device.eecs.berkeley.edu/~viveks/ are making conducting ink, out of gold nanocrystals. a traditional inkjet printer can print these, or even screenprint (which is how product packaging is down) [i like that idea. have multiple stages. print circuits, hit with radio to computer, print more circuits, hit with radio to compute more. so it's like a growing *running* computer.] another field: "flexonics": devices on-demand [there's a URL at the bottom of this slide, but I can't see it] combination of three technologies . 3d printers -- used for rapid prototyping plastics . organic electronics -- print electronics and packaging all at once . novel actuators -- similar to shape memory alloy, musclewire. wires produce voltages when you squeeze them together gives you this: a printer that does all three -- people are building this at the moment. casing, electronics, actuators, all printed at once layer by later from an electronic file, all as different inks. [this is like the real world non-general case of Drexler's *thing*-printer. it's computer chips to the turing machine. now all we need if for someone to prove that anything that can be built using generalised nanotech can also be built with this kind of printer... hey, that's interesting: the nanotech version is actual kind of inefficient. why throw away all that accumulated de-entropy to make nanodust, only to have to accumulate it again? is there a model anywhere of the effort to create order? much better to do it centrally, in the inks themselves, so this printer only puts in high level order.] another field: "smart dust". self-assembling networks for environmental monitoring, smart buildings. smart dust motes: wireless transceiver. hundreds of thousands of them, running TinyOS. data hops through the network. power supplies: - a battery that lasts a decade - scavenging power from vibrations. office walls vibrate a bit from air conditioning, so you get it from that. mix them up in paint, paint them on the way. another field: Microrobots . MEMS based, fabricated like integrated circuits are fabricated. these are things that can be printed and stamped out really cheap. . solar-powered . autonomous more in the future: "robofly" like smart dust with *wings* this guy says he things this technology changes the way we view the world. "it turns the whole world into a database that we can query and interact with" ==== This guy saying that people are constantly touching, constrantly looking across the room, just to make eye contact, just to look around. "It may be a bit geeky, but you're just pinging the person." Just to say, I've seen you, you seen me, that's it. Graph of types of communication: X axis is "ambient". Y axis is "richness". We can Mobile Personal Ambient Always-On devices. Because you can multi-leaf. Generation Txt . social connectivity and entertainment will be primary chars of wireless devices . young people will build relationships . most are highly social and experimental . mobile . intolerant of poorly designed devices The devices that people carry... provides emotional thing constant connection -- that's why people carry mobile phones. [this is all based on studies] Why is SMS good? . stealth/ nondistruptive . rapid disseminiation, always on . anonymity/ physical transendence -- the identity thing Some new media being experimented on . camTouch . inTouch . Phone Bracelet (PaPR) . Scent (RCA) . Media Cup (Karlsruhe) At Intel: Connexus, trying to implement the "glancing" sort of awareness as a bracelet, and it picks up: force sensing (moving), light, pulse and then replicates it on the other side so it all goes through a central server. what they found is that it's so *personal* that people don't want to recieve messages from many people. they exchange the device and it's just the other person they'll feel, that one person. there's no meaning, you decide your own embedded messages. you tap one bracelet, and feel it on the other one. [um. all these touching bracelet thing.. him and his girlfriend it's all a bit masturbatory. everyone gets the joke.] so eventually they want to be able to send the pulse. pulse on one side means a little glow on the other. now he's saying the same thing with a dog. what does it do all day? [so this is like the microsoft metrics thing. a complex metric of dog behaviour maps to a glow of the bracelet, or if it's a rare thing maybe the bracelet vibrates. you have an awareness of what it's doing all day] other things: context aware gaming, tagging & message play he claims there's a communication between you and your community by tagging, leaving messages around in the environment. grafitti. [this is the semiotcracy. we have to have this ability to join messages to anything, otherwise we can't communicate.] familiar stranger: you have a relationship with strangers at a train station. you have an agreement with them to ignore them without any implications of hostility. the further you are from routine encounter, more likely to interact "socio-metric stars" [<-- this was quoted, what does it mean?] imagine all these strangers are wearing these bracelets, or the scents. just sounds and mp3s and events. get back to work and it syncs and you can see what was going on. have fun playing with this idea without engaging in dialogue. wardriving is kind of similar. lots of *message play* you can do. [it's all about play. no other reason to communicate with these people. it's fun! that's important, and valid.]
