GAME DEVICE CONTROLLING METHOD

PURPOSE:To develop a game enriched with in interests by providing a strain degree sensor for detecting the strain degree of an operator from his palm of a hand and reading out the output of the strain degree sensor before an image of a question is displayed to provide basic data for comparing the output with an output read out after the question is displayed. CONSTITUTION:The outputs of a perspiration sensor 28 and pulse sensor 30 are read by an operating device 16, and basic data is read in timing preceding the timing when a first question is displayed on a display device 10. When an operator seeing the image plane of the question depresses a button on an operating board 12 to show his answer, the operating device 16 corresponds to the result to change the display. At every fixed time thereafter, the data of the sensor 28 is read. Before the operator sees the question on the display device 10, this strain degree corresponds to the calm condition, so that the reference level at this time is read to be stored as reference data. The operating device 16 displays the strain degree overlapping the image plane being displayed on the display device 10.
