Taste The Television: TTTV

Associate Professor [Homei Miyashita] from Meiji University’s School of Science and Technology in Tokyo has developed a new technology for reproducing taste on a television or monitor, a system called Taste the TV (TTTV). The team of researchers used taste sensors to sample a variety of foods, and came up with a palette of 10 different aerosol flavors which can be combined in various ratios. The taste is generated in a staging area at the top of the screen onto a thin plastic film, which is then scrolled down into position.

Possible applications shown in the video below the break include cooking programs, restaurant menus, and wine tasting events. We’re not quite sure how popular this would be to consumers. Tele-tasting a cooking show with friends would be inconvenient, if not unsanitary. We’re also not aware that current video interface protocols such as HDMI or ATSC include any provisions for senses other than sight and sound. If you have access to scholarly journals, [Prof Miyashita] research paper on TTTV is available in the 34th Annual ACM Symposium on User Interface Software and Technology.

We’ve written about a couple of taste-generating projects before, see here and here.

Taste-O-Vision Is Now A Thing


Not satisfied with late 1950s concepts of Smell-O-Vision [Nimesha]  has created something extraordinary: A digital taste sensor, capable of representing taste with a little bit of heat, electricity, and an Arduino

The device purportedly works by via thermal and electrical stimulation of the tongue using silver electrodes. According to this video, different tastes are created with different currents and temperatures. For example, a sour taste is produced on the electrodes by varying the current from 60uA to 180uA and increasing the temperature up to 30 degrees C. Mint is produced by simply decreasing the temperature from 22C to 19C.

The control electronics include an Arduino, a motor controller, and a heat sink attached to one of the silver electrodes. Communication is done through USB, and of course there’s a mobile app for it, more specifically a protocol called Taste Over IP. This allows anyone to send a taste to anyone with one of these devices.

Videos below, and before you laugh, we’d really like to try one of these out.

Thanks [Jess] for the tip.
