EaTheremin (Eat + Theremin) is a fork-type device that  enables users to play various sounds by eating foods. This device changes the act of eating into practical daily entertainment.
Potential applications of this device include a device for motivating eating for small kids who do not like to sit and eat foods.

//**研究背景 Background[#x3dc5deb]

**動作原理 Mechanism[#g9263297]



The device has two electrode in fork grip and tines. 
When a user grip the fork, put food at the tines, and eat, an electronic circuit with fork, food and human body is made.
EaTheremin generate various sound according to the resistance between the electrodes. 
Since the resistance value often varies by several features of foods (e.g., types, length, or thick- ness) and movements of the user, the device plays sound reflecting eating actions. 

//食べテルミンにはアナログとデジタルの二種類を作成しました。アナログ食べテルミンには、握り部分にDrawdio互換回路とスピーカを内蔵しています。デジタル食べテルミンでは、抵抗値をArduinoで読み込み、予め用意したMP3音源を選択して音を出しています。We developed two prototypes, Analog EaTheremin and Digital EaTheremin, which generate sounds in different manners. Analog EaTheremin generates simple sound (sine wave) according to the resistance. Digital EaTheremin generates pre-recorded sounds (e.g., onomatopoetic words) depending on the resistance.}}
