Face Electrodes Let You Taste and Chew In Virtual Reality (newscientist.com)

walterbyrd quotes a report from New Scientist: Experiments with "virtual food" use electronics to emulate the taste and feel of the real thing, even when there's nothing in your mouth. This tech could add new sensory inputs to virtual reality or augment real-world dining experiences, especially for people with restricted diets or health issues that affect their ability to eat. Several projects have succeeded in tricking us into tasting things that aren't there. Nimesha Ranasinghe at the National University of Singapore has already experimented with a "digital lollipop" to emulate different tastes, and a spoon embedded with electrodes that amplify the salty, sour, or bitter flavor of the real food eaten off it. However, his experiments with electrical stimulation had less success simulating sweetness compared to the other tastes. But digitizing this taste could be particularly useful in, for example, helping people cut back on sugary food or drinks. So Ranasinghe and his colleague Ellen Yi-Luen Do started experimenting with thermal stimulation instead. Their new project, presented at the 2016 ACM User Interface Software and Technology Symposium (UIST) in Tokyo, uses changes in temperature to mimic the sensation of sweetness on the tongue. The user places the tip of their tongue on a square of thermoelectric elements that are rapidly heated or cooled, hijacking thermally sensitive neurons that normally contribute to the sensory code for taste. In an initial trial, it worked for about half of participants. Some also reported a sensation of spiciness when the device was warmer (around 35 degrees Celsius) and a minty taste when it was cooler (18 degrees Celsius). Ranasinghe and Do envisage such a system embedded in a glass or mug to make low-sugar drinks taste sweeter.

    Diabetes can be caused by consuming too much sugar, but if you cut back on the amount but still preserve the same taste, you start treading down the very dangerous path of insulin resistance as well. Your body will stop making the proper amount of insulin for what it detects in taste because it's used to lack of sugar, and you'll wind up with diabetes all the same - it's only an effective way to allow somebody whose body already doesn't produce or absorb the proper amount of insulin to satisfy a sugar craving. However, this does have some great potential for MMO games and cooking websites and the like - while taste is arguably our least useful sense in such an environment, such a sensor might find a place for allowing people to preview recipes before they cook them or such.

      Well, from what I can find and what I know, yes. Tasting sweetness alone triggers insulin, at least according to this research report, and a forum for diabetics agrees with this also. So, while artificial sweetener probably has less impact than consuming the real deal, it's obviously not a way to enjoy ridiculously sweet foods without any repercussions since you'll still have a blood sugar level crash afterwards, and this taste machine wouldn't provide much over artificial sweetener in terms of diabetes prevention or guilt-free sugar surges.

      Even without the diabetes connection I would beware the obesity link. Your brain learns the connection between taste and the actual amount of sugar it gets. If you give it repeated "sweet taste" stimulus without the follow-up sugar-hit (say through "diet" soda, or this) and the system will learn the new normal and start to crave even more sweet (because your new source of sweet is obviously a bit weak). Which is why diet soda is a really, really bad idea: it trains your brain on bad data, so you *will* eat a lot more cake and chocolate along with that feel-good, zero-cal non-sugar water.

      Remember: your brain evolved when food was scarce and energy input mattered. Lazy tricks simply will not work (and may harm): you need to do the hard yards to retrain that neural-network, and even then there are no guarantees.

      Glad I wasn't the only one. But yes, smell is very much intertwined with east. I have two friends with Chron's, and the medicines for each knocked out their sense of smell and taste. The one guy decided that eating was boring and lost a lot of weight - no problem because he needed to. The other guy needed to have his wife as part of the healing process - doctors told her she had to nag him to eat even if he didn't want to.

      That guy eventually got to go off his meds - I think it was remicaid (sp?) or somthing like that, and his sense of smell came back while in the office. Never saw a mid 50's guy so excited. Now he's sporting a bit of a belly.

      Synesthesia - awesome! I also have an enhanced sense of smell, which brings up a pet theory of mine. I find that women smell really good, and men do not - to me. I'm not talking about perfume or unclean body odor, but an inherent smell to each sex. Women just smell good. And I find a relationship between the smell and who I find attractive. I have always suspected that people might be noticing a smell that doesn't quite reach their threshold of sensation, but react to it anyhow.

      Which has always made me wonder about the idea of sexual orientation as inborn or a choice. I never chose to find the inherent smell of women attractive, but it tells me something about myself.

    "I woke up and my pillow was gone"

    I think it's actually a good idea to venture down this road, but we need to be careful not to create dangerous situations (eg "eating fire/acid") that would normally be deadly in reality because it may induce people to try it in reality. Or worse, people might think they are still in the game (eg GTA-like games) or develop a motion-memory about it.

    For the most part I believe that VR is just going to be an utter fail, but the ability to trigger taste/touch/smell would go a long way into improving VR. Right now the inability to feel anything is the first reason why VR isn't really usable, controllers are not a viable input device. It would be possible to induce a heart attack in someone with VR visuals or touch senses (eg cutting someones arm off with a hack saw) because the body believes it's happening when it's not if we venture down this road without safety.

    VR already makes people sick, even if it's not "supposed to", because not everyone is tuned the same way. I'm sure there will be more than a few people who have a barely high end enough VR system who get so sick from it that they will never try it again.
