Next: looking beyond the device in digital health | Consumer Controlled Health Information |

Observers of the digital health ecosystem seem addicted to the idea that it is accretive when in truth it is commutative.


News of the demise of sleep tracker Zeo, theclosure of Google Reader through which many of us have reviewed health news, and the imminent  withdrawal of the best (IMO) version of the best Twitter client through which many health tweet chats have been conducted should hopefully serve to remind us of the transitory nature of digital environments.


Personal health data is certainly going to continue to be collected. It will be at the centre of our genome-informed, personalised medical future.

However, we aren’t going to be collecting it via a panoply of trackers, gadgets, wristbands and glasses.


We no more want external health peripherals than we do a keyboard for a tablet computer. They are extraneous, inconvenient, and will only be used by health hobbyists.


Nor are we ultimately going to want to see that data collected by a smartphone-like device. Mobile devices, whether carried, or viewed via a HUD contact lens, or placed on the back of our hand as a removable skin-like overlay, may be a great way of reviewing data, but in the last instance we don’t want integrated onboard sensors tracking our data for the sole reason that it requires us to remember or desire to continue to collect it, even if the process is passive.


This needn’t mean a Matrix-like plug of course, but rather a sensor of whatever sort that merely gathers data.


However, not everyone wants to be a cyborg, nor will it be necessary to be one in order to enjoy the long terms health benefits of fully quantifying (and adapting) our health behaviours.


Assuming that we don’t all succumb to the beguiling technological singularity, the paradigm will be inverted and the social face of health will be human rather than a mimetic poly-alloy.


The future of quantified health will reside in non-invasive sensors that will become as ubiquitous and cheap to use as the bar code, incorporated not only into public spaces but also into products and packaging. Aggregated personal data is Big Data by any other name, and will facilitate the study of health trends and behaviours at a population level.


This may sound like science fiction.


However, aspects of the transformation of  digital health into a non-invasive sensor-facilitated model are just a few steps down its evolutionary pathway.


So let’s look beyond the device-driven quantified self.


We’re not still discussing what happened to our Walkman, pocket calculator PDA, diary, Filofax, digital camera, and so on, and nor do we need to talk about how everything that can be integrated into mobile devices will be, because we already know it’s going to happen.


There are more interesting questions to ask of the future of digital health, such as....
