Human Performance Measurement Inc HPM has a family of modular instruments engineered to characterize the human system quantitatively. Each works with a user-supplied host computer that runs HPM's "BEP for Windows" software and produces measures of important parameters from data acquired during well-defined test trials. Results are stored in a local database and presented in raw form with scientifically accepted units (e.g., centimeters, Newtons, seconds, bits, etc.) as well as in a compact graphical Z-score format.
