A toilet with facial recognition for your butthole

From Nature.com (emphasis added):

Here, we describe easily deployable hardware and software for the long-term analysis of a user’s excreta through data collection and models of human health. The ‘smart’ toilet, which is self-contained and operates autonomously by leveraging pressure and motion sensors, analyses the user’s urine using a standard-of-care colorimetric assay that traces red–green–blue values from images of urinalysis strips, calculates the flow rate and volume of urine using computer vision as a uroflowmeter, and classifies stool according to the Bristol stool form scale using deep learning, with performance that is comparable to the performance of trained medical personnel. Each user of the toilet is identified through their fingerprint and the distinctive features of their anoderm, and the data are securely stored and analysed in an encrypted cloud server. The toilet may find uses in the screening, diagnosis and longitudinal monitoring of specific patient populations.

tl;dr — Data gathering for toilets using biometrics of your anus. Got it? Okay cool.


The article itself is paywalled, as far too many academic articles are, but one Twitter user shared screenshots of this screening, diagnosis, and longitudinal monitoring technology:

Other pages explain:

We performed 410 fingerprinting [Ed note: butthole] trials from 10 participants … Among 11 participants, two video clips of the anus per participants were acquired from 7 participants, whereas one video clip of the anus per participant was acquired from 4 participants … As an input, individual frames of the anus from participant 1 were used for identification purposes.

British man's colon bursts due to an abundance of poop

That poop you’ve been holding in until you get home? Stop it: use a restroom as soon you can. The wind you’re not breaking because you’re only on your fourth date? Make an excuse to walk away from the table and let it rip. Working your way through a keto diet and haven’t had a dump in a few days? Ingest large amounts of Psyllium husk, stat.

Good God, just read this, from Ars Technica:

Doctors are urging caution after a 24-year-old UK man underwent emergency surgery when they discovered that his severely enlarged colon, filled with feces, had burst.

At the time of the surgery, the man had “reduced consciousness” and severe abdominal pain, as well as air trapped under his diaphragm, failing kidneys, and acidic blood.

In a short communication published this week in BMJ Case Reports, doctors elaborated on the man’s rare conditions, known as “megacolon” and “megarectum.” These are poorly-understood ailments marked by enlarged entrails that aren’t caused by a physical blockage. Sometimes they can be explained by genetic abnormalities or other acquired conditions, such as diseases that affect intestinal motility or muscle and connective-tissue function. But in this case, the man seemed to have a chronic, idiopathic case, meaning there was no clear cause of the gargantuan guts.

Apparently he a long history of constipation. In a great deal of discomfort, he came to his local hospital’s emergency department, looking for help. The doctors on duty, assuming it was just a typical log jam, gave the pained individual marching orders to head on home and sort things out using laxatives and self administered enemas. Read the rest
