Remember how far-fetched lifelike robots and self-driving cars used to sound? Now, theyre a reality. And thanks to new research, theres another seemingly improbable technology thats come to life: teleporting a drink. Earlier this month, researchers out of the National University of Singapore and Georgia Institute of Technology presented a method for creating virtual lemonade.还忘记人工智能和自动驾驶汽车曾多次听得一起有多很远吗？而如今它们都沦为了现实。好在了一项新的研究，另外一种看起来不可思议的技术问世了：远程传输饮料。

本月早些时候，新加坡国立大学和佐治亚理工学院的研究人员明确提出了一种建构“虚拟世界柠檬水”的方法。Lets say you cant make it to your cousins summer shindig, but Grannys going to be there making her beloved lemonade. No worries. Using the researchers method, Granny could send you some of the beverage simply by mounting and submerging an RGB color sensor and pH sensor in a glass of her lemonade. (Color affects the drinkers flavor perceptions, and pH affects the drinks acidity.) The taste messaging would then occur via Bluetooth communication, when a control module sends the color and sourness information to a custom tumbler youll soon be sipping Grannys refreshing lemonade out of.假设你无法参与表妹的夏季聚会，但你的外婆又会在聚会上制作她最擅长的柠檬水。不必担忧，只要外婆依照研究人员的办法，在她制作的一杯柠檬水中加装一个 RGB颜色传感器和一个 pH 传感器（颜色不会影响饮酒者的味觉感官，pH值影响饮料的酸度），就可以将柠檬水传输给你。

一个掌控模件不会通过蓝牙通信将颜色信息和酸度信息发送到一个自定义玻璃杯上，让你迅速享用到外婆制作的清新柠檬水。But you, the virtual lemonade receiver, are actually drinking a cup full of plain H2O. The special tumbler has a rim of silver electrodes that serve as a sourness simulator, giving off 800-Hz pulses to tempt your taste buds. An LED (light-emitting diode) device at the bottom of the tumbler gives off a mini light show by diffusing color through the water. Youll only be drinking water, but youll experience simulated lemonade flavors. So, mind over matter?但实质上，你喝的是一杯白水。这种类似的玻璃杯有一圈银电极当作酸性模拟器，该电极不会收到800赫兹的脉冲来冲击你的味蕾。

玻璃杯底部的 LED装置首演一场微型灯光秀，让颜色在水中蔓延。你喝的只是水，但不会滋味仿真的柠檬水味道。这就叫心胜于物？Researchers gave 12 different real and virtual lemonades to 13 participants. The team used tasteless food coloring agents to make the real lemonades green, cloudy and yellow, and LED lights to color the virtual lemonades similarly.研究人员给13名参与者12种有所不同的柠檬水（既有知道，也有虚拟世界的）。

研究小组用于无色食物着色剂让确实的柠檬水变为绿色、混浊和黄色，他们也用LED 灯让虚拟世界柠檬水变为相近的颜色。Participants reported the real lemonade tasted sourer than the virtual. But overall, there were no statistically significant differences in their perceptions of real and virtual flavors, so teleporting lemonade could turn out to be a sweet deal. The team hopes this study leads to further analyses, like extending virtual flavor technologies for multisensory interactions like toasting drinks, or even sharing digital signatures of beverages stored in a virtual cloud.参与者对系统，确实的柠檬水比虚拟世界的柠檬水更加酸一点。但总的来说，数据统计资料表明，他们对确实的柠檬水和虚拟世界柠檬水的感觉没明显区别。

结果证明，远程传输柠檬水显然不切实际。研究小组期望这项研究能更进一步，将这种虚拟世界味觉技术扩展到多感官交互，比如喝酒，甚至还可以共享存储在云盘里的虚拟世界饮料数据。
