Imagine watching your favorite cooking show and being able to experience its flavors right in your own home; or traveling with an exciting travel show and being able to sample local cuisine as it unfolds right before your eyes! While this might sound like science fiction, recent advancements in technology may soon make this reality; so meet “TV screen that lets you taste.”
Imagine being able to taste what you see on a television screen: although this idea might seem unbelievable, digital taste has actually been around since 2002 and early experiments were performed back then. With recent technological advancements however, we are now able to take this concept one step further.
Digital Taste Synthesis technology enables TV screens to produce food-like flavours through electrical and chemical signals that stimulate taste receptors on your tongue, mimicking their flavor profiles of different foods. This technique has long been utilized by food companies as an artificial flavoring technique and to improve processed food flavors.
Recently, however, this technology has only recently made its debut in entertainment. To create a television screen that lets you taste food, the first step involves creating a digital signal to mimic its taste; this can be accomplished by analyzing chemical constituents of food before activating taste receptors on your tongue using electrical and chemical stimulation signals to generate taste sensations.
Once the digital taste signal has been generated, it can be delivered to viewers through various means – including television screens, special devices connected to them or smartphone apps – so they can use their tongue to pick up on it and taste what’s being displayed on-screen.
A TV screen that allows viewers to taste is boundless in its potential applications. Cooking shows could use this technology to enable viewers to experience real-time taste-testing of dishes being prepared on live cooking shows; travel shows could use it to give their audiences an immersive taste experience of local cuisine in each destination being highlighted on screen.
Technology behind TV screens that let viewers taste has already been demonstrated in various settings. In 2019, researchers from National University of Singapore created a prototype device allowing users to taste virtual flavors through electrical and thermal signals applied directly to taste receptors on the tongue – creating the sensation of taste sensation.
Rekimoto Lab of Japan in 2020 created the Norimaki Synthesizer device, which enables users to sample different flavors by placing a small strip of film on their tongue. Using both electrical and thermal signals, Norimaki Synthesizer stimulates taste receptors on your tongue for an immersive sensorial experience of taste sensations.
Even with all these advances, some obstacles remain before creating an interactive TV screen that lets us taste. One key challenge lies in designing taste signals to accurately mimic different foods; to do this requires understanding their chemical makeup as well as creating precise electrical and chemical signals which stimulate taste receptors on the tongue.
Another challenge lies in crafting devices that are accessible and affordable. While the technology that powers TV screens that enable consumers to taste has been demonstrated on various occasions, its complexity makes mainstream adoption difficult and expensive. To become mainstream, this technology needs to be further refined so it is more easily adopted by average consumers.
Even with these difficulties, the potential benefits of TV screens that allow us to taste are evident. This technology could revolutionize how we experience entertainment.
