This research designed EMG signal controlled virtual menu. There were 9 menu items inside which were arranged in a 3×3 matrix. An EMG signal from the jaw was used to operate the virtual menu. There were five commands to operate the virtual menu: Selecting menu items, up searching, down searching, left searching and right searching. Threshold value of amplitude was used to recognize contraction of the jaw. The duration of the EMG signal exceeding the threshold value called the Timer was used to produce five commands. Fourteen volunteers examined the system. The result shows that a 100 μV threshold for amplitude and 5 Timers used in this research can recognize 98.8% of 840 activities. Six scenarios of tasks from three trajectories were designed to be completed by operators. The result shows that operators can finish all the tasks. The real time spent by operators for those activities was nearly the same as the designed estimated time. The virtual menu was also reviewed based on the operation tiredness, the difficulty in executing selecting and searching commands and the comfort of having the electrodes attached to the jaw skin. Almost 80% of the operators could operate this device without a negative issue. But attaching the electrodes to the jaw made a challenge because it caused discomfort on the operators.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Daily activity,duration,EMG signal,Menu items,Real time,threshold,Threshold-value,virtual menu[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]duration,EMG,threshold,virtual menu[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.1109/ACIRS.2018.8467273[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
