Galvanic Tongue Stimulation

What is ELECTRIC TASTE?:

​​-Electric Taste is a taste sensation you feel when your tongue is electrically stimulated.
Generally everyone can experience sourness, bitterness, saltiness and metallic taste

APPARATUSES TO ADD ELECTRIC TASTE TO FOOD and DRINK

-We made the apparatuses look like eating utensils (cups and forks) for greater acceptability.
We proposed Polar opposite type apparatuses and Single-pole apparatuses to apply various stimulus.
These apparatuses have a potentiometer to control output voltage individually.

COMMUNICATION BY CHANGE IN TASTE(CHI2011)

-We can use physical contact as the means to switch the circuit on and off.
We use this system for drinking/eating together and body contact.

TASTE SHAREING

-Shareing an electric taste recipe is easily by its waveform data via a delivery site.
When you want to reproduce it you adjust the waveform by an amp.

AUGMENT THE SENSE OF TASTE(AH2011)

-the difference between exhale and inhale can be recognized by the taste device if sensor values change into an Electric Taste pattern and then outputted.

VIEWING SYNCHRONIZED WITH EATING(CHI2012)

-We can detect whether user “eat or not” by checking the change of current.
We can synchronize change of tastes to our other senses like visual or auditory.

ENHANCING SALTINESS WITH CATHODAL CURRENT (CHI2013)

-Salt is necessary for life. However, we often tend to consume too much salt.
Despite the high risk for high blood pressure and other diseases, most people find it difficult to decrease salt intake.
However, it may be possible to reduce salt intake by increasing the perceived saltiness of food.
Weak cathodal current applied to the tongue inhibits the taste of salt,but perceived saltiness tends to increase after the current is released.
Using this phenomenon, we develop a saltiness enhancer, which can non-intrusively control the taste of food.
