What is it about?
Our study shows that some signals collected from smartwatches are different when the device is on the right or left hand. Our results demonstrates that one side (left or right) might yield more informative signals, depending on the task performed.

Why is it important?
We demonstrated that the current suggestion, or placing wrist-worn wearable devices on the non-dominant hand, could lead to lower performance in some scenarios. Researchers should consider these results when performing data collection, and smartwatch makers when implementing new products.
Perspectives
Writing this article was really fun and it allowed me to challenge myself with many wearable-related problems. From the work performed, we also published two python libraries, one for detrended cross-correlation analysis and one for effect size analysis, which I also hope could be useful to the public at large. It was also wonderful to be able to collaborate with the co-authors, without whose knowledge and insights the work could not have been possible.
