Taste+

Taste+

Taste+ aims to promote a healthier lifestyle by replacing unnecessary amount of condiments in our daily consumption of food and beverages. It overlays virtual taste sensations on food and beverages and enables people to experience digitally augmented taste sensations while eating and drinking. To achieve this technology, we use weak and controlled electrical pulses on the tip of the tongue and overlay different colors using RGB Light Emitting Diode LED (while eating and drinking). The ability of this technology to simulate primary taste sensations such as salty, sour, and bitter has made us able to merge this technology into everyday eating and drinking utensils such as spoon and beverage bottle, thus to augment the taste sensations of food and beverages.

Technology and Design

Simulated taste sensation

Taste+ utensils send controlled electrical pulses to the users' tongue through the silver electrodes attached. By controlling the frequency and the amplitude of current, we are able to enhance taste sensations perceived by overlaying virtual taste sensations such as salt, sour, and bitter. The dial interface on the utensil allows users to change these properties thus augmenting the existing taste sensations of food and beverages.

Visual Stimulation

Different colors of the RGB LED provides an additional layer of visual stimulation to make the taste sensation more accurate and visually more appealing. The red light corresponds to red wine - bitter mode, green light corresponds to lime green - sour mode, and the blue light corresponds to ocean blue - salty mode.
