Researchers at Tokyo University have developed virtual/augmented reality devices that can manipulate a person's senses. So, that they taste and look at food differently. In one of their initial experiments, they utilized a color-changing cup to manipulate people into thinking that a drink taste different, based on the color of the drink. Furthermore, they developed a table that changes the plate size, in order to change a person's perception of how much they ate. Lastly, the researchers produced a virtual reality headset that can change the size of a cookie and how it taste. These technologies can have the implications to change how much an individual can eat, especially if on a diet and the availability of what we can taste.
