Method for hypotheses making and testing about user mental actions in human-computer interaction

The new method is offered for hypotheses making and testing about user mental actions in human-computer control systems. This method is used to create interface design for the control systems taking into consideration their specific character. The method is based on the critical-path method and its methodical and mathematical tools. The linear model of interface is used as input data. The analysis of critical-path chart allows making reasonable corrections to the source model and increasing its accuracy.
