One or more non-transitory computer-readable storage media having stored therein a program causing a computer to perform information processing when executed by one or more processors, an information processing system, computer implemented method

An information processing system comprising:

• one or more processors;
• a first controller comprising a first mouse sensor and a first inertial sensor;
• and
• a peripheral device to which the first controller is detachably attached so as to cover an opening to the first mouse sensor;
• one or more non-transitory recording media that cause a computer to execute information processing when executed by the one or more processors,
• wherein the information processing comprises:
• in a first mode, operating a first virtual object based on output from the first mouse sensor;
• in a second mode, operating the first virtual object or a second virtual object based on output from at least one of the first inertial sensor or a first sensor further provided in the first controller, without operating the first virtual object based on output from the first mouse sensor;
• changing from the second mode to the first mode based at least on the opening to the first mouse sensor being covered;
• and
• changing from the first mode to the second mode based at least on the opening to the first mouse sensor being covered, movement in two-dimensional directions indicated by the first mouse sensor being smaller than a first value, and movement of the first controller indicated by the first inertial sensor being greater than a second value.

A computer-implemented method comprising:

• in a first mode, operating a first virtual object based on output from a first mouse sensor of a first controller configured to be detachably attached to a peripheral device that covers an opening to the first mouse sensor;
• in a second mode, operating the first virtual object or a second virtual object based on output from a first sensor of the first controller, without operating the first virtual object based on output from the first mouse sensor;
• changing from the second mode to the first mode based at least on the opening to the first mouse sensor being covered;
• and changing from the first mode to the second mode based at least on the opening to the first mouse sensor being covered, movement in two-dimensional directions indicated by the first mouse sensor being smaller than a first value, and movement of the first controller indicated by a first inertial sensor provided in the first controller being greater than a second value.
