Abstract
Human beings are doing a smooth communication with the auditory, visual and haptic information. Multimodal interfaces are obtained by utilizing the communication method of human to human-machine interface. Machine operation assist could be improved by visual and auditory information given the time difference in presentation. In our study, the validity of multimodal assists with time difference is experimented by vibration control task of a pendulum. Four types of operation assisting was compared time to complete vibration control. The four types of operation assisting are #1: without assist, #2: with only visual assist, #3: with visual and auditory assists (no time difference) and #4: with visual and auditory assist (100ms delay for the auditory). Experimental results show that giving a time difference to the information presentation is effective in the machine operation performance.
