This article presents a research on the benefits of using double mousing devices in computers, as compared to using the orthodox single-mousing device.

The study shows that it's safer, from an ergonomic perspective, to be able to offload some mousing operations from the dominant hand to the less dominant hand, it improves accuracy and it often improves personal productivity. This article describes some of the academic studies that underlie these assertions and observations, discuss some of the pragmatic aspects of bi-manual mousing, and illustrate some of the alternatives available for consideration.
