With fast internet connexions and almost unlimited connectivity, medical consultations from your house or your smartphone are not something that seem impossible to achieve in a - not so distant - future.
Only requiring a free software and a webcam, a research team evaluated the joint position of the head. The results were similar to those found in studies with much more expensive setups.
Even if I do not feel comfortable, in some specific cases, doing a full consultation through webcam, we can find some nice features to those affordable technologies. Like gathering gigantic databases of “normal values”, sent by millions of individuals around the world, in order to define mean / standard data to which practitioners could refer.
