Just doing a bit of free reading between classes.
Has anyone compared wearables on the basis of workload?

Mental workload was already identified as a critical criterion for acceptance of assistive devices in the 1970s and the rise of myoelectric prostheses
In a human-computer interaction context such as that of wearable assistive devices, mental workload can be considered as the “demand placed on the user by the system” 7.
or the same task, two people will not have the same mental workload, depending on their initial capacities, their experience, their reaction to time pressure or fatigue, etc.
a robotic rehabilitation device that is too complex to use could negatively impact the patient’s motivation 9 and limit his or her involvement in the recovery process 10, greatly affecting the overall beneficial therapeutic effect 11.
You gotta check out these references.
While walking is considered an activity requiring little or no cognitive effort for an able-bodied person, the use of a lower limb prosthesis or exoskeleton requires a high level of concentration
Oh wow.
The mental workload caused by the use of assistive devices thus becomes a major consideration for the ecological/realistic use of assistive devices and their long-term adoption.
It is therefore crucial to be able to assess the mental workload imposed by the use of assistive devices, to ensure that the devices designed generate a minimal mental workload so that they can actually be usable and used.
In this way, an interface like any other.
Cognitive modelling allows to estimate the complexity of a task and the time needed to perform it by breaking it down into small simulated mental steps. It can therefore be used to evaluate the mental workload induced by a task without having to actually perform it.
Preach.
From one of the graphics of the paper, it looks like around 2% of studies on workload use cognitive modeling. And with the other categories that it is compared to here, Skin, Eye, Heart, Brain, its easy to see why; those other measures are simple to observe and measure. But modeling gives you much more latitude about conclusions one can make now and in the future.
A query mentioned: prosthesis “mental workload”
