Buongiorno nexiani, dalle informazioni che ho letto, **mi pare** che questo sistema sia stato progettato per l'uso generalizzato quotidiano. Purtroppo l'articolo è dietro paywall e io quindi sono escluso dalla conoscenza... anzi non solo io, siccome questa è scienza con la S maiuscola: «the medical training and validation data [...] are therefore not publicly available» e «codes (source code, n.d.r.) may be available from the authors on reasonable request, after permission [...]» Tipo: come e perché funziona non ve lo diciamo (a meno che firmiate un NDA bla bla bla) ma fidatevi, funziona! :-D https://www.nature.com/articles/s41551-020-0534-9 (è una evoluzione di qualcosa di simile già pensato in passato) --8<---------------cut here---------------start------------->8--- A mountable toilet system for personalized health monitoring via the analysis of excreta Abstract Technologies for the longitudinal monitoring of a person’s health are poorly integrated with clinical workflows, and have rarely produced actionable biometric data for healthcare providers. 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. Data availability Restrictions apply to the availability of the medical training and validation data, which were used with permission of the participants for the current study, and are therefore not publicly available. Some of the data may be available from the authors on reasonable request, after permission from the Stanford University School of Medicine and/or the Seoul Song Do Hospital. Code availability The codes may be available from the authors on reasonable request, after permission from the Stanford University School of Medicine and/or Seoul Song Do Hospital. --8<---------------cut here---------------end--------------->8--- Nicola Davis di The Guardian che ha potuto leggere lo studio ne rivela alcuni dettagli e aneddoti: https://www.theguardian.com/society/2020/apr/06/magic-toilet-could-monitor-u... --8<---------------cut here---------------start------------->8--- 'Magic toilet' could monitor users' health, say researchers [...] “We have developed a passive human health monitoring system that can be easily incorporated into a normal daily routine, requiring minimal or even no human intervention,” the team behind the new toilet report. [...] They hope it will eventually become a “daily clinic”, helping in the prevention and early detection of problems from diabetes to urinary tract infections and inflammatory bowel diseases. [...] In addition, the system incorporates cameras that take images of users’ stool. These images are then classified using a machine-learning system – a type of artificial intelligence [...] [...] the team report that the system detects who is using the toilet from a fingerprint scanner on the flush handle, and “analprints” – distinctive creases in the lining of the anus, captured by video frames. [...] However the team say there is more to do, not least in testing the device in large clinical studies – so far a total of 21 participants have tested the toilet. They also stress the need to develop self-cleaning mechanisms to avoid false positives in the tests, adapt the system to squatting toilets, and redesign the urine analysis system for women, as it is currently designed for users who stand up while having a pee. They also hope to expand the range of tests to screen for illicit drug use, sexually transmitted infections and the makeup of microbes in the gut. [...] But whether the system will prove popular is another matter. In a survey of 300 individuals near Stanford University who were asked to rate what they thought of the proposed toilet, 30% said they felt uncomfortable with it, primarily citing privacy concerns, with the analprint the most disliked component. [...] Prof Tim Spector, an expert on the gut microbiome from King’s College London, who was not involved in the research [...] “The future will be either a magic toilet paper that gives you this result or these magic toilets that will give you a chemical analysis basically of the chemicals your microbes are producing, to give a snapshot of your inner health,” he said. --8<---------------cut here---------------end--------------->8--- Saluti, Giovanni -- Giovanni Biscuolo Xelera IT Infrastructures
