Detailed Description

Evaluates how good Presage is at doing its job (in other words, its ability to reduce keystrokes the user is required to type).

Simulator computes the KSR (Keystrokes Savings Rate) obtained by using Presage preditive ability compared to manually entering text.

The KSR is computed as ( 1 - ( ki + ks ) / kn ) * 100, where ki is the number of input characters actually typed ks is the number of keystrokes needed to select among the predictions presented kn is the number of keystrokes that would be needed if the whole text was typed without any prediction aid.

The simulator is built with a reference to a Presage object which simulates and takes a string holding the text to be run through the simulation. Multiple calls to the simulate method can take place. Each call runs the string through the simulator. The results of each simulate call update the internal state of the simulator object. The results of the simulation can be retrieved at any time by invoking the results method or the get methods.
