The sharing of tasks between the human and the cobot in a collaborative workspace is an important activity, however the question arises how to quantify the tasks, of the human, the cobot and at the end of the collaborative workspace, for example in an assembly process?
Hi Alejandro Chacón ,
Based on previous works, I developed a psychological scale to measure four perspectives of human-cobot interaction fluency (the human contribution, the human emotion, the perception of robot contribution, and the human-robot team interaction). Maybe it can be useful for you? The article with the scale can be found here: https://www.sciencedirect.com/science/article/abs/pii/S0921889022001105
Best regards!

Hello Alejandro Chacón ,
the metrics to quantify a task depend on the goal you want to achieve: find an optimal task allocation (with respect to performance or ergonomics), ensure safety, etc.
Examples of metrics are efficiency (e.g. capability indicators), fluency (e.g. concurrent activity or fluency scales), task flexibility (e.g. neglect tolerance, teaching time), physical ergonomics (e.g. strain index), and cognitive ergonomics (e.g. workload).
A colleague and I have summarized metrics for assessing human-robot teaming. Many of them can be used (or built upon other metrics) to quantify sub-aspects of tasks: Article Benchmarking Teamwork of Humans and Cobots – An Overview of ...
What would be the values from the VSD (Values Sensitive Design) considered in an HRI workspace?
I have not come into contact with VSD so far. Some values that we consider metrics in our paper:
Values of business:
* Productivity increase
* Required flexibility
Values of workers' compensation board/law enforcement:
* Safety
Values of the user:
* Technological acceptance
* Appropriate workload
* Trust
As I understand, VSD is a comprehensive framework to identify those values. The metrics described in our paper are a good starting point but need to be filtered for the use case at hand. Explorative, qualitative studies are a potential next step to discover additional values or refine the list.
