Abstract (in Japanese) (See Japanese page) 
(in English) Currently, Home Network System (HNS) attracts a great deal of attention. This system can provide value-
added services with connecting various home appliances to the network. We have already developed an integrated
service which enables the integrated operation of more than one home appliance with using Web services in our
previous study. In this paper, we did an evaluative experiment of the integrated service to show its utility in HNS.
In this experiment, we set some typical tasks with operations of the integrated service and consumer appliances,
and then we conducted usability testing to operate the appliances by the subjects actually. In the evaluation, we
evaluated from the viewpoint of the operation efficiency and the satisfaction rating by comparing the operations of
each usual appliances and integrated service in HNS. We were able to confirm that all subjects completed the tasks
of the integrated service from this experiment. Moreover, we could obtain the result in which the average operation
time was a half or less in the maximum, and the average number of errors was 1/10 or less in the integrated service
compared with the usual operation. We were also able to obtain the result that the satisfaction rating of the service
was 1.5 times or more high in the integrated service compared with the usual operation in all tasks.
