Estimating Productivity: Composite Operators for Keystroke Level Modeling
Task time is a measure of productivity in an interface. Keystroke Level Modeling (KLM) can predict experienced user task time to within 10 to 30% of actual times. One of the bigges...

Left invertibility of discrete-time output-quantized systems: the linear case with finite inputs
This paper studies left invertibility of discrete-time linear output-quantized systems. Quantized outputs are generated according to a given partition of the state-space, while inp...
