Simulation control device and information storage medium

A non-transitory computer-readable information storage medium storing a simulation control program for use with a sensor, a processor or circuit, the simulation control program causing the processor or circuit to perform steps comprising:

• displaying a virtual space on a wearable image display device;
• measuring a gaze time of a user with respect to an object that is placed in the virtual space via the sensor;
• determining a measured value based on the measured gaze corresponding to a time in which the user gazes at the object during a gaze time period;
• determining that the object, at which the user gazes, has been selected by the user when the measured value is equal or greater than a first threshold value and increasing a size of an area within the virtual space that is considered to include the object to a first size;
• determining that the selection of the object is confirmed when the measured value is equal or greater than a second threshold value that is larger than the first threshold value and increasing the size of the area within the virtual space that is considered to include the object to a second size that is greater than the first size;
• during measuring within the gaze time period and when the user has removed their gaze from the object, decreasing the measured value of the user's gaze in accordance with a period of time in which the user has removed their gaze from the object;
• determining that the selection of the object has been canceled when the measured value has decreased to a third threshold value;
• and
• setting a first determination standard for determining that the user is gazing at a selected object, to be less than a second determination standard for determining that the user is gazing at an unselected object.
