1. A system for performing sensory evaluation on a plurality of sensory indexes corresponding to respective feelings of an occupant according to traveling of a moving body, the system comprising:
one or more sensors to acquire information according to the traveling of the moving body, the information including (i) road surface information on a road surface on which the moving body travels and (ii) at least one of acceleration information on an acceleration of the moving body and angular velocity information on an angular velocity of the moving body; and
one or more microcomputers configured to:
generate evaluation data to be used for the sensory evaluation, based on the information by:
generating time-series data of at least one of the acceleration information and the angular velocity information as the evaluation data; and
making at least one of a time range and a time interval of the time-series data different for each of a plurality of evaluation circuits;
select, based on the road surface information, at least one sensory index as an evaluation index from among the plurality of sensory indexes;
calculate evaluation values for the evaluation indexes from the evaluation data using the evaluation circuits corresponding to the evaluation indexes;
aggregate the evaluation values; and
output or display a result of the aggregated evaluation values.
