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. You'll only be drinking water, but you'll experience simulated lemonade flavors. So, mind over matter?
但实际上,你喝的是一杯白水。这种特殊的玻璃杯有一圈银电极充当酸性模拟器,该电极会发出800赫兹的脉冲来冲击你的味蕾。玻璃杯底部的 LED装置上演一场微型灯光秀,让颜色在水中扩散。你喝到的只是水,但会尝到模拟的柠檬水味道。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种不同的柠檬水(既有真的,也有虚拟的)。研究小组使用无味食物着色剂让真正的柠檬水变成绿色、浑浊和黄色,他们也用LED 灯让虚拟柠檬水变成相似的颜色。
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.
