Anthropomorphism and enmachinement severely limit the operator's ability to operate complex man-machine interfaces.

Pierre-Paul Vidal

Human behavior relies on complex neural processing in multiple networks that cross-reference data from motor and sensory systems, including in operators of complex man-machine interfaces.  One of the mechanisms involved is the concept of efference copying. It is used to predict the sensory consequences of a specific behavioral action in progress, thus making it possible to dissociate self-generated (reafferent) sensory information and extrinsic sensory information ie generated by interactions with the environment. Efference copies are major contributors to internal training models, which predict future body states by taking into account recent and current efferent signals, which are thought to contribute to changes in the state of target effectors.

These mechanisms also apply to tool manipulation. In this context, embodiment can be defined as the ability to develop hybrid internal models, including the body and an object, to model body dynamics complemented by that object. We propose to use the term enmachinement instead of embodiment to distinguish the case where the object to be controlled is a complex machine rather than a simple hand-operated tool.

Given the increasing complexity of machines over the last century, the question of the limits of enmachinement arises. In other words, is it biologically plausible for the central nervous system to develop precise hybrid internal models that fuse the characteristics of complex machines such as helicopters, airplanes and their operators? It's clearly possible, since pilots effectively control their aircraft, but we propose that this has a cost....and limits.

Perceptual-Motor Style: Static and Dynamic

Danping Wang

The concept of style to the study of normal and pathological behavior, and define perceptual-motor style as any distinctive and recognizable way of performing an action or processing a perception. The sensorimotor behavior is generally variable due to noise, redundancy, adaptability, learning or plasticity. However, the idea that part of this variability depends on unique individual strategies has been explored to a lesser extent. The application of the term to the domain of perceptual and motor phenomenology opens new perspectives on the nature of behavioral variability, perspectives that are complementary to those typically considered in the studies of sensorimotor variability. In particular, the concept of style may help toward the development of personalized physiology and medicine by providing markers of individual behavior and response to different stimuli or treatments. Humans exhibit various motor styles that reflect their intra- and interindividual variability when implementing sensorimotor transformations. This opens important questions, such as, At what point should they be readjusted to maintain optimal motor control? Do changes in motor style reveal the onset of a pathological process and can these changes help rehabilitation and recovery? To further investigate the concept of motor style, several quantitative methods were used to quantify both internal and external characteristics of individuals. These results can be used for individual longitudinal monitoring.
