Can AI-driven health apps, developed with artificial knowledge, pump up your exercise?
In the course of the COVID-19 pandemic, residence health apps have been all the fashion. From January by means of November 2020, roughly 2.5 billion well being and health apps have been downloaded worldwide. That pattern held and reveals no indicators of slowing down, with new knowledge predicting progress from $10 million in 2022 to $23 million by 2026.
As extra individuals use health apps to coach and observe their growth and efficiency, health apps are more and more utilizing AI to energy their choices by offering AI-based exercise evaluation, incorporating applied sciences together with pc imaginative and prescient, human pose estimation, and pure language processing strategies.
Tel-Aviv-based Datagen, which was based in 2018, claims to offer “high-performance artificial knowledge, with a give attention to knowledge for human-centric pc imaginative and prescient purposes.”
MetaBeat will carry collectively thought leaders to provide steerage on how metaverse know-how will rework the way in which all industries talk and do enterprise on October 4 in San Francisco, CA.

The corporate simply introduced a brand new area, Good Health, on its self-service, visible artificial knowledge platform that helps AI builders produce the information they should analyze individuals exercising and prepare sensible health gear to “see.”
“At Datagen, our focus is to assist pc imaginative and prescient groups and speed up their growth of human-centric pc imaginative and prescient duties,” Ofir Zuk, CEO of Datagen, instructed VentureBeat. “Virtually each use case we see within the AI area is human-related. We’re particularly attempting to unravel and assist perceive the interconnection between people and their interplay with surrounding environments. We name it human in context.”
Artificial visible knowledge represents health environments
The Good Health platform offers 3D-annotated artificial visible knowledge within the type of video and pictures. This visible knowledge precisely represents health environments, superior movement, and human-object interactions for duties associated to physique key level estimation, pose evaluation, posture evaluation, repetition counting, object identification and extra.
As well as, groups can use the answer to generate full-body in-motion knowledge to iterate on their mannequin and enhance its efficiency rapidly. For instance, in instances of pose estimation evaluation, a bonus the Good Health platform offers is the potential to rapidly simulate totally different digicam sorts for capturing a wide range of differentiated train artificial knowledge.
Challenges to coaching AI for health
Pose estimation, which is a pc imaginative and prescient method that helps decide the place and orientation of the human physique with a picture of an individual, is among the distinctive options that AI has to supply. It may be utilized in avatar animation for synthetic actuality, for instance, in addition to markerless movement seize and employee pose evaluation.
To accurately analyze posture, it’s essential to seize a number of pictures of the human actor with its interacting setting. A educated convolutional neural community then processes these pictures to foretell the place the human actor’s joints are situated within the picture. AI-based health apps typically use the system’s digicam, recording movies as much as 720p and 60fps to seize extra frames throughout train efficiency.
The issue is, pc imaginative and prescient engineers want huge quantities of visible knowledge to coach AI for health evaluation when utilizing a method like pose estimation. Information involving people performing workouts in numerous varieties and interacting with a number of objects is very advanced. The info should even be high-variance and sufficiently various to keep away from bias. Amassing correct knowledge which covers such a spread is sort of not possible. On high of that, guide annotation is sluggish, liable to human error, and costly.
Whereas a suitable degree of accuracy in 2D pose estimation has already been reached, 3D pose estimation lacks by way of producing correct mannequin knowledge. That’s very true for inference from a single picture and with no depth data. Some strategies make use of a number of cameras pointed on the particular person, capturing data from depth sensors to realize higher predictions.
Nevertheless, a part of the issue with 3D pose estimation is the dearth of huge annotated datasets of individuals in open environments. For instance, massive datasets for 3D pose estimation akin to Human3.6M have been captured completely indoors to get rid of visible noise.
There may be an ongoing effort to create new datasets with extra various knowledge concerning environmental circumstances, clothes selection, sturdy articulations, and different influential elements.
The artificial knowledge resolution
To beat such issues, the tech business is now broadly utilizing artificial knowledge, a kind of knowledge produced artificially that may intently mimic operational or manufacturing knowledge, for coaching and testing synthetic intelligence techniques. Artificial knowledge gives a number of important advantages: It minimizes the constraints related to the usage of regulated or delicate knowledge; can be utilized to customise knowledge to match circumstances that actual knowledge doesn’t enable; and it permits for big coaching datasets with out requiring guide labeling of knowledge.
Based on a report by Datagen, the usage of artificial knowledge reduces time-to-production, eliminates privateness considerations, offers lowered bias, annotation and labeling errors, and improves predictive modeling. One other benefit of artificial knowledge is the power to simply simulate totally different digicam sorts whereas producing knowledge to be used instances akin to pose estimation.
Train demonstration made easy
With Datagen’s sensible health platform, organizations can create tens of 1000’s of distinctive identities performing a wide range of workouts in several environments and circumstances – in a fraction of the time.
“With the prowess of artificial knowledge, groups can generate all the information they want with particular parameters in a matter of some hours,” Zuk stated. “This not solely helps retrain the community and machine studying mannequin, but in addition means that you can get it fine-tuned very quickly.”
As well as, he defined, the Good Health platform optimizes your skill to seize tens of millions of considerable visible train knowledge, eliminating the repetitive burden of capturing every component in particular person.
“By way of our always updating library of digital human identities and train sorts, we offer detailed pose data, akin to areas of the joints and bones within the physique, that may assist analyze intricate particulars to boost AI techniques,” he stated. “Including such visible capabilities to health apps and units can considerably enhance the way in which we see health, enabling organizations to offer higher providers each in particular person and on-line.”
Health AI and artificial knowledge within the enterprise
Based on Arun Chandrasekaran, distinguished VP Analyst at Gartner, artificial knowledge is, to date, an “rising know-how with a low diploma of enterprise adoption.”
Nevertheless, he says it should see rising adoption to be used instances for which knowledge have to be assured to be nameless or privateness have to be preserved (akin to medical knowledge); augmentation of actual knowledge, particularly the place prices of knowledge assortment are excessive; the place there’s a must steadiness class distribution inside present coaching knowledge (akin to with inhabitants knowledge), and rising AI use instances for which restricted actual knowledge is obtainable.
A number of of those use instances are key for Datagen’s worth proposition. In the case of enhancing the capabilities of sensible health units or apps, “of specific curiosity would be the skill to spice up knowledge high quality, cowl the large gamut of eventualities and privateness preservation in the course of the ML coaching section,” he stated.
Zuk admits that it’s nonetheless early days for bringing AI and artificial knowledge, and even digital applied sciences total, into the health area.
“They’re very non-reactive, very lean by way of their capabilities,” he stated. “I’d say that including these visible capabilities to those health apps, particularly as individuals train extra in their very own residence, will certainly enhance issues considerably. We clearly see a rise in demand and we are able to simply think about what individuals can do with our knowledge.”
