This led us to suggest that target information together with
visual aid during cooperative task could increase the
cooperative task smoothness. In the future, since we already
knew that cooperative task movement is smoother when human
using visual aid, we want to know the effect of auditory signal
during the start of experiment and its contribution to humanhuman
cooperative task smoothness. Will adding auditory aid
also increase smoothness? We hope to find these answers
regarding all the human senses and its effect to the cooperative
task smoothness in order to apply to our human-like robot
design.
