Patent ID: 7160253

Claim:
A method of measuring mental load, the method comprising: measuring, by an electronic device, at least one pulse parameter; generating, by the electronic device, at least two different cognitively loading tasks for the person participating in the measurement, the first task determining a reference level and at least one other task determining the loading capacity level; determining, by the electronic device, at least two pulse parameters related to the at least two different cognitively loading tasks for the person participating in the measurement; comparing, by the electronic device, the pulse parameters during the different tasks with each other; and generating, by the electronic device, a value descriptive of the mental load of the person participating in the measurement on the basis of the comparison of the pulse parameters, the first task used to determine the reference level being based on reflexive action and the at least one other task used to determine the loading capacity level being based on the use of memory.
