Virtual Drinks Hacks Your Senses Using Lights, Scents And Electrodes To Make Water Taste Differently

A zero-calorie mojito? World's first virtual cocktail hijacks your senses using lights, scents and electrodes to make water taste like your favourite drink

• 'Vocktail' can change a glass of water into a Mojito or a glass of wine via an app
• The technology tricks your brain into thinking it is experiencing a flavour
• It uses LED lights, tongue electrodes and scent canisters to fool your senses
• Virtual drinks could be used to satisfy your taste buds without any of the calories

A 'virtual cocktail' glass that lets you change the flavour of your drink using your smartphone has been developed by scientists.

Offering a customisable range of drinks and tastes, the 'Vocktail' can change a glass of water into a Mojito at the press of a button.

The world-first technology tricks your brain into thinking it is experiencing a specific flavour by fooling your senses of sight, smell and taste.

Virtual drinks could one day be used to satisfy your taste buds without any of the calories by turning water into your favourite beverages, experts claim.

HOW IT WORKS

The world-first technology tricks your brain into thinking it is experiencing a specific flavour by fooling your senses of smell, taste and sight.

Smell: The 3D-printed glass houses three scent cartridges connected to micro airpumps.

The pumps release 'smell molecules' that change your perception of the beverage's flavour, the researchers claim.

Taste: On the rim of the glass are two electrode strips, which send electric pulses into your tongue to stimulate your taste buds.

A jolt of 180 microamps mimics a sour taste, while 80 microamps gives a bitter taste and 40 microamps a salty taste.

Sight: The Vocktail also tricks the brain using an LED light system at the base of the glass.

The colour corresponds to the drink, meaning a maroon light is shone when drinking a red wine, while a bright orange is shone for a Sex on the Beach.


Developed by researchers at the National University of Singapore, the glass's three sensory components are controlled via a smartphone app.

Because the software can combine a number of smells, colours and tastes, the Vocktail can create almost any flavour, the scientists claim.

Lead developer Dr Nimesha Ranasinghe said: 'Our approach is to augment beverage flavour experience by overlaying external sensory stimuli.

'For example, in the Vocktail we overlay colour, taste and smell sensations to create an adjustable flavor experience.

'Flavour is mainly how we perceive food and that's achieved through the use of these senses.

'Therefore, by changing the colour of the drink, using a different smells and changing the taste through electricity, we are able to simulate the flavor of a drink, without it actually changing the liquid.'

For example, a lemon scent will trick your brain into believing it is tasting a lemon-flavoured drink.

On the rim of the glass are two electrode strips which send electric pulses into your tongue to stimulate your taste buds.

A jolt of 180 microamps mimics a sour taste, 80 microamps gives a bitter taste and 40 microamps a salty taste.

On top of taste and smell, the Vocktail also fools the brain using an LED light system at the base of the glass.

The colour is altered to correspond to the drink - a maroon light is shone when drinking a red wine, while a bright orange light accompanies a Sex on the Beach.

Dr Ranasinghe said: 'We are currently working on not only increasing the number of smells, but also a silent release mechanism.

The researchers are now working on increasing the number of smells available, as well as a silent release mechanism for the scent canisters

'The reason behind having an app is to empower the users to augment the existing flavours, enabling them to experiment and create flavours of their own.

'However, we know that simulating our sense externally is not as convincing as the real taste of the drink, so we're constantly conducting experiments to create an even more immersive experience.

'We want to bring it to pubs and bars, but we need industry partners to bring it out of the lab and into reality.'
