How does RSIGuard compute/measure strain?
Each action you do during working at the computer affects the strain calculation. Keyboard strain is a function of which keys you use (e.g. Ctrl-X causes more strain than plain X, and Shift-Ctrl-F9 causes more than Ctrl-X) as well as how quickly you type. A period of time with no typing relieves some keyboard strain, moreso if there is no mousing either. Mouse strain is a function of how much mouse moving you do combined with how much clicking, dragging, double-clicking, etc. Each action is assigned an appropriate amount of strain and actions that take advantage of AutoClick features are appropriately reduced in assigned strain. Again, a period of time without mousing relieves accumulated mouse strain. Although there are other factors, this is the basic idea behind BreakTimer’s strain calculation. For the more math minded, the unit for strain is arbitrary but absolute, constant, and comparable between a user over time as well as between different users. In the display that shows typing
