The rise of the drones

The ever increasing ability and availability of drone technology will have a major impact on defence and law-enforcement operations in the future.  Where capabilities of platforms used to be defined by the ability to deploy various assets within the capability of a class or type of vessel ( in naval operations for example, a carrier vs an offshore combatant vessel), the latter smaller platforms may soon be able to deploy an aerial capability which could previously only be provided by the larger and far more expensive vessels.

As noted in the article, this can have far-reaching consequences for navies where the majority of tasks are routine patrol and ‘constabulary’ operations of protecting sea lanes and territorial integrity.  With drone technology, a single smaller platform could perform tasks which currently require several more capable and expensive assets (for example, the patrol of a shipping route subject to piracy).

A telling point made in the article is the close involvement of the human in the loop.  Similar to other advances in automation, the command and control function remains within the human domain.  As stated “…there will inevitably be a human in the operational Observe, Orient, Decide and Act (OODA) loop – be they a remote operator, data handler oFull diagram originally drawn by John Boyd for...r decision maker within any of a number of mission sets.”

So the design of the HMI will determine how successful this shift in technology will be.  As has been seen in Afghanistan, the ability of the remote operator of a drone aircraft to gain and maintain situational awareness to perform their mission without unintended consequences will greatly depend on the amount, type and quality of information available to them and what range of tasks they need to perform.  Many combat aircraft have a crew of two due to the separate and demanding pilot and SA/engagement tasks, and military drone strike operations seem to reflect this crewing model. Perhaps this model is a historical legacy which may also change in the future as drones dispense with the constraint of having to fit the aircrew into the platform.

This may cause a shift in emphasis of the Human Factors and Ergonomics discipline.  A lot of effort was traditionally expended in the physical anthropometric ergonomics aspect of the human in the loop probably because it was so obvious. For example, range of movement, posture etc within a cockpit could be calculated and the 95thpercentile adopted as a standard which could then be used to determine interaction within the crew space available in the airframe. As we all know, engineers love standards, so perhaps this aspect was pursued to the detriment of equally or possibly more important aspects of the human/machine interface.

Computer Workstation Variables

Similar adoption of standards cannot be readily applied to much more esoteric aspect of neurological interaction with a system. For example, although it provides a very good framework to predict and test how an operator will interface with a HMI, Multiple Resource Theory doesn’t provide the level of certainty available from physical ergonomic models. Each aspect needs to be tested according to the many variables which could arise and the neural adaptability inherent in the human which makes them so important to the command and control function.  That’s why the non-physical human interaction field is so interesting to us practitioners (and perhaps perplexes many physical scientists who cannot seem to grasp the notion that humans cannot be treated as a simple probability or linear contributor in their decision models).

So while drone technology will enhance capability, it will only do so effectively if there is a requisite paradigm shift in how the interface is designed to incorporate the more difficult ‘neural ergonomic’ aspects described above.  Perhaps we can finally move away from the tyranny of standards which are sometimes adopted without further thought for the equally important sensory, perceptual and cognitive aspects which we pesky Human Factors types are constantly trying to highlight to our seemingly dullard peers in other fields, sometimes with, but unfortunately many times without success.

  2. Hi, just wanted to tell you, I loved this blog post. It was
    funny. Keep on posting!

  3. Hey there! I just wanted to ask if you ever have any issues
    with hackers? My last blog (wordpress) was hacked and I ended up losing a few months of
    hard work due to no back up. Do you have any solutions
    to prevent hackers?
