Tech could probably start narrowing down health solutions for people. I wonder. Theorycrafting for a moment.
Someone who owns facial recognition cameras, could also analyze a swarm of other features, by the means of big tech style research and development. Gait analysis, body temperature with millimeter wave scanners, pose and skeletal estimation, arm->body ratio, skin pallor, hair length, face mood and health markers, maybe analyse mouth or teeth images with enough resolution and correct camera angle.
With pose estimation and kinematic animation you could start harvesting body language and mannerisms. Common ticks, impulsive behaviour can be grouped together.
If you also record and analyze speech, across phones and mall microphones, one could isolate out tourettes (and some speech pathologies?).
An awful lot of vaguery could be made clear...
I wonder if treating these diagnostic conditions like a programming language and organising the diagnostic routes properly, we could allow for a technique for the user in combination with a properly designed website, to individually narrow down their own experience into a doctors apppointment, and waste less resources on 'wild goose chase' doctor appointments, intiated by clueless patients.
What ever happened to Watson's autodiagnosing abilities?
