Galvanic Tongue Stimulation (GTS) is the technique that can induce electrical taste or metallic taste virtually and inhibit and enhance taste induced by water solution. This technique is expected to use for diet support device. However, conventional GTS required to attached electrodes in the mouth. It causes uncomfortable to use for the purpose. Therefore, we invented Galvanic Jaw Stimulation (GJS) which induces and modulates taste without electrodes in mouth. In this paper, we demonstrated whether GJS can induce virtual taste and modulate salty taste induced by NaCl water solution.
