- akennberg 14y agoMedicine and military applications would be great! Dentist: How dentist grips the tool indicates how it behaves. Eg. control speed of a rotary tool like a drill based on a grip. Doctor: Patient giving doctor feedback with their hand. Military: For some guns, one finger on the trigger does a single shot for precision, two fingers does bursts for rapid fire.
- swohns 14y agoThese guys did a killer demo at NYTM. Very cool demo of turning a plant into an instrument (they played an orchid on stage). There was a good question about detection of differing touches of the doorknob, this could totally replace the key some day!
- josh_blum 14y agoHow can this differentiate between users though? Can the frequency be replicated?
- stephengillie 14y agoSome of that may depend on precision - how precise is the sensor? Can it pull a fingerprint, so it will basically do a fingerprint scan to authorize door unlocking? I'm reminded of #66 on the Evil Overlord list - My security keypad will actually be a fingerprint scanner. Anyone who watches someone press a sequence of buttons or dusts the pad for fingerprints then subsequently tries to enter by repeating that sequence will trigger the alarm system. http://www.eviloverlord.com/lists/overlord.html http://www.eviloverlord.com/lists/overlord.html
- hrayr 14y ago#99 Any data file of crucial importance will be padded to 1.45Mb in size. Ah, sign of the times. This list was compiled in 1996.
- raphman 14y agoA persons 'capacitive footprint' depends on skin moisture, clothing, anatomy, etc. This allows Touché to distinguish certain users from each other in a lab setting. As this approach uses only a single electrode (which is why it is so cool), the data it offers is quite limited compared to more complex sensor layouts. In real life, such a sensor would need to work reliably even if I wear different shoes, have dirty hands, etc. Therefore, its false rejection rate needs to be very low. Which leads to a high false acceptance rate, i.e. several other people with similar capacitive footprints may open my door, too.
- btn 14y agoThe authors of Touché did a follow-up paper at UIST this year to study this exact question [1]. In brief, you can train a classifier on the impedance profile of specific users, but there are some significant limitations (impedance profiles naturally drift over time, and accuracy doesn't look so good with a lot of users).

- joshschreuder 14y agoThat sounds like Makey Makey (http://www.makeymakey.com/ http://www.makeymakey.com/), though that's based off a simple electrical circuit which is different to this I think.
- frankdenbow 14y agoWhen was this at NYTM?
- davidtyleryork 14y agoGo CMU! We might not start as many startups as MIT but our research is some of the best in the world. #proud
- Nav_Panel 14y agoAlways HCI (or Robotics) too. It's like, you never actually see what they're doing but it's always awesome (except for that large robot in some room on NS second floor right near the Wean bridge, but that might not be HCI). Also #proud :)
- epenn 14y agoI think (?) the room on NS 2 you're thinking of is part of the Quality of Life Technology Center. <3 CMU and #proud. Can we all agree that the robot in the Gates 3 lounge area is somewhat creepy-looking though? His avatar looks like a cross between Julian Assange and Andy Warhol.
- jQueryIsAwesome 14y agoWhenever I want to feel excited about the future I just look at this video; seriously is really magic stuff. Changing your bathtub temperature with one gesture of your hand in the water; changing the channel by a simple gesture in the couch, the use-cases are virtually unlimited. Also if one day it becomes even more sensitive it could transform any object into a fingerprint detector!
- manveru 14y agoYou might want to watch http://www.youtube.com/watch?v=lm5TdgQj7vg http://www.youtube.com/watch?v=lm5TdgQj7vg then.

- akavi 14y agoI really liked the demo controlling the music player; it struck me as the one I'd be most likely to actually see in the near future (The door with the different signs was neat, but requires a bit more hardware). I'm curious where the sensors were placed for that one (I couldn't see them on the guy's arms) and if say, getting caught in the rain or a really dry day, would throw it on the fritz.
- lewisgodowski 14y agoAren't the sensors placed within the door? Or am I missing something?
- est 14y agoIs forecasting baby urination possible with sensing electrical signals?
- antidoh 14y agoWhat would you do with that information? The diaper gets wet, sometime today.
- pirateking 14y agoThis is too cool. I cannot wait to try how a manipulatable material and holographic interface feels. Glad to see Bret Victor's important rant[1] resonating as well. Does anyone have any tips about getting involved with this area of work? Any good forums or open source projects? [1] http://worrydream.com/ABriefRantOnTheFutureOfInteractionDesign http://worrydream.com/ABriefRantOnTheFutureOfInteractionDesi...
- raphman 14y agoThere is little "open source" research on hardware for novel user interfaces. Most of this stuff is published at scientific conferences like CHI, UIST, ITS, TEI. As "novelty" is quite important for publishing one's work at these conferences, there is little incentive for doing open research. Some nice stuff and communities can be found at http://nuigroup.com/forums http://nuigroup.com/forums or http://hackaday.com/ http://hackaday.com/ (btw: Bret Victor apparently pulished his rant _after_ Touché had been submitted to CHI.)
- pirateking 14y agoI figured. Thanks for the links though, lots of interesting stuff there. (I remember seeing this video when it was posted months ago as well, but thanks for clarifying the timing as to which event came first.)
- GuiA 14y ago>Does anyone have any tips about getting involved with this area of work? Do a PhD :) ralphman has it spot on. Even the non-academic companies who do this (Disney Research, Microsoft Research, etc.) will usually prefer hiring PhDs. Doing a PhD in HCI is fun, challenging, will drive you insane, and is very rewarding! (I dropped out of mine after 2 years to do the startup thing but intend on going back :) )
- gregsq 14y agoThere's lots of prior art here, thinking of patents. You might want to look at Atmel's maXTouch capacitive sensors. In particular what's going on with the noise floor, or signal to noise that's a relevant factor for resolution [1]. And a side band attack btw. Infrared sensors are affected greatly by environmental infrared, so dual transmitter types and fast switch sampling and interferometric approaches. You'll need to consider high sampling rates both in the time and frequency domains. There's other stuff but I'll keep mum about that. 1. http://www.atmel.com/microsite/maxtouch_eseries/ http://www.atmel.com/microsite/maxtouch_eseries/
- atpaino 14y agoGoogle must be all-over this for their Glasses. Seems like it would be a great solution to the input problem with them.
- rrmm 14y agoI always have a kind of negative reaction to these sorts of interfaces. What I tend to see in this demo is how to make a doorknob unintuitive, how to make music player functionality undiscoverable, how to accidentally lock yourself out, how to frustrate a user whose mental model of the sensor is incorrect. I realize you have to approach new technology and interaction paradigms optimistically, but all I can think of is my own frustration when an ill-considered neato-feature is foisted on me when I least want it. Like blue LEDs and touch sensitive buttons that lack a physical button (eg atmel q-touch).
- redguava 14y agoIt's up to the developer to make it usable, that doesn't take away from the fact that it's pretty amazing technology and people will find really cool stuff to do with it. I just wouldn't blame the tech for bad implementations.
- rrmm 14y agoI don't blame the tech. I'm just anticipating all the ways this is probably going to be used and am annoyed at those developers in advance. :D
- redguava 14y agoAgreed if I have to start pinching my door handle to lock it then I won't be impressed. Consider me an optimist though, I have faith in our fellow developers... even if there are a few blemishes on their record.
- rrmm 14y agoI won't fault you for your optimism: technological advancement thrives on it.
- wladimir 14y agoA tech demo is a tech demo, it shows what is possible, not what is necessarily feasible to market to the big public as a new UI metaphor. Often it takes a long time to perfect something. So no need to be negative. Don't confuse it with a commercial of something that is actually brought to market.
- lewisgodowski 14y agoI believe Avatar Land at Walt Disney World will include this technology for interacting with the Tree of Souls and other plant and wildlife.
- yozmsn 14y agoThis is kinda old, I saw a video about this on the verge a couple months ago...
- czr80 14y agoYes. We must hide it away and never speak of it again.
- babebridou 14y agoI might be going on a tangent here, but I can't help thinking there's something wrong with product names for the past few years. We're now naming things with incredibly common words, changing their very meaning into something else. Facebook, Touché, Bonjour, Spaces, Windows... For some reason, it's creeping me out. I'm afraid to see one of those next big thing named Lundi, Ball, Tisch or Hora. It's like we're robbing our languages of their meaning, bit by bit, for commercial purpose. We can do better than that, can't we?
- icebraining 14y agoWith some exceptions, I don't think brand names are eclipsing the common definitions of the words, but just appending new definitions to them, which can easily be distinguished based on context - not unlike any other non-branded word with multiple definitions. And we also gain new common words from brands that become generic, like Tabloid or Bikini.
- stonemetal 14y agoAnd we also gain new common words from brands that become generic, like Tabloid or Bikini. Bikini isn't a brand that became a generic word. It is a loan word from the native Marshall Islanders(http://en.wikipedia.org/wiki/Bikini_Atoll http://en.wikipedia.org/wiki/Bikini_Atoll), that was stolen for a brand then became generic. Which ironically proves his point.
- icebraining 14y agoBikini isn't a brand that became a generic word It is. The fact that the brand name itself was derived from an existing proper noun doesn't change that fact. And speaking of language abuse, I feel that some day the verb 'steal' will be synonymous with every possible offense. How does one steal an island name?
- Mordor 14y ago"recognition rates approaching 100%" - how many times do we hear this? Basically it doesn't work, except for a set of carefully constructed circumstances.
- akeck 14y agoI think this tech could give robots much more data from physical human contact.
- nerdfiles 14y agoConsidering that autistics and empaths tend to have remarkably rich gestural languages for communicating a wide array of non-verbal units of meaning, or even propositions, and further that allocentric language may present scoped indexicals (and not to mention Ame. Sign Language), we may have an opportunity to develop interestingly rich gestural/touch APIs from the mechanics of neurologically rooted gestures which describe or underpin norms of highly complex, spontaneously emergent non-verbal communication. For instance, would finger-flipping or self-stimulation be considered "noise" to such a system, or would the system be configurable or adaptive or "fuzzy" enough to make successful interpretations of various deviant forms of model human behaviors? (I'm wondering the intersection between these types of interfaces and the training (or, say, auto-designing) of them via neural networks.)
- mleonhard 14y agoThis could be used to give robots a sense of touch over their entire bodies.
