For those celebrating Thanksgiving today, at some point there will come a time where you is simply too full to move. At this point, the sensible action is to sleep it off before rising later in the day, groggy and disorientated, for a second gorging. But what if technology could help? What if, instead of succumbing to your turkey stupor, some sort of chest-mounted robot arm could lob sweet treats into your open mouth? What a world that would be.
We’ve not reached this gravy-soaked utopia yet, but researchers from Australia and India have taken us one step closer with “Arm-A-Dine” — a robot arm worn in the middle of the chest that picks food up off the table and conveys it to you or your dining partner’s mouth.
The intention isn’t to stuff you till you explode, though: Arm-A-Dine is actually a prototype designed to augment the social experience of eating. In a research paper from the Exertion Games Lab at RMIT University in Australia and the Indian Institute of Information Technology Design, researchers explain how most food tech is focused on the preparation of food and not the eating experience.
In a world where researchers warn about a “loneliness epidemic” and many meals are taken with smartphone in hand, Arm-A-Dine is supposed to remind us that eating is a social event.
So, Arm-A-Dine not only grabs food from the table, but also makes a judgement on who to feed it to. A facial recognition app running on an attached smartphone scans your dining partner’s expression. If they’re smiling, your arm offers them the food; if they’re frowning, you get it. (And if the expression is neutral, the arm hovers ambiguously in the middle.)
You can watch a video of Arm-A-Dine below (which we spotted via IEEE Spectrum):
Arm-A-Dine is not a commercial project (at least not yet) and the limitations of the hardware are obvious. The arms can only grab certain items, have limited degrees of movement, and don’t seem to be that accurate when it comes to actually feeding people. (The paper notes: “The gripper stops 10 cm away from the wearer’s mouth for safety reasons.”)
But as the paper notes, this weird robot arm really does succeed in making eating a more socially-engaging experience. Testers said using Arm-A-Dine made them nostalgic (“it reminded me of my mother feeding me when I was a child”) and encouraged them to concentrate on eating (“I had to focus […] in order to pick it up [food] properly”).
Testers even embraced the clumsiness of the arm itself, as it meant they had to work around its limitations and engage with the person opposite, rather than just relaxing and being. As one tester noted: “The most exciting bit was when the third arm moved strangely in the air. It felt as if the arm was teasing us by fluttering between both our mouths.”
So remember that next time you sit down to dinner. When your dining partner complains that you really shouldn’t “wave food around the table” or “waggle potatoes in my face,” just tell them “I’m augmenting the social experience of dining,” before silently stuffing your face.
