A pressure-sensing type massage chair system comprising: pressure sensing units (S1, S2, S3, S4, S5) installed in any one or more of at least a seat portion , footrest portions , a backrest portion , armrest portions , a headrest portion , and combinations thereof and configured to detect movement of any one or more of at least user's hips, feet, back, hands, head, and combinations thereof, or a change in a user's center of gravity; a first command signal output unit configured to receive pressure signals from the pressure sensing unit (S1, S2, S3, S4, S5) and match the received pressure signals with pre-input first command matching information to output a first command signal corresponding to the first command matching information; a control unit configured to receive the first command signal from the first command signal output unit and apply any one or more of at least a seat control signal for controlling the seat portion , a footrest control signal for controlling the footrest portion , a backrest control signal for controlling the backrest portion , an armrest control signal for controlling the armrest portions , a headrest control signal for controlling the headrest portion , and combinations thereof; characterised in that the system is further comprising a command start time detecting unit configured to detect a command input start time, wherein the command input start time detected by the command start time detecting unit is a "body-ON-head-OFF" time point at which the pressure signal is not generated in the pressure sensing unit (S5) installed in the headrest portion while the pressure signals are being generated in the pressure sensing units (S1, S2, S3, S4) installed in the seat portion , the footrest portions , the backrest portion , and the armrest portions , or the command input start time detected by the command start time detecting unit is a simultaneous input point in time at which at least two or more of the pressure signals are simultaneously input. pressure sensing units (S1, S2, S3, S4, S5) installed in any one or more of at least a seat portion , footrest portions , a backrest portion , armrest portions , a headrest portion , and combinations thereof and configured to detect movement of any one or more of at least user's hips, feet, back, hands, head, and combinations thereof, or a change in a user's center of gravity; a first command signal output unit configured to receive pressure signals from the pressure sensing unit (S1, S2, S3, S4, S5) and match the received pressure signals with pre-input first command matching information to output a first command signal corresponding to the first command matching information; a control unit configured to receive the first command signal from the first command signal output unit and apply any one or more of at least a seat control signal for controlling the seat portion , a footrest control signal for controlling the footrest portion , a backrest control signal for controlling the backrest portion , an armrest control signal for controlling the armrest portions , a headrest control signal for controlling the headrest portion , and combinations thereof; characterised in that the system is further comprising a command start time detecting unit configured to detect a command input start time, wherein the command input start time detected by the command start time detecting unit is a "body-ON-head-OFF" time point at which the pressure signal is not generated in the pressure sensing unit (S5) installed in the headrest portion while the pressure signals are being generated in the pressure sensing units (S1, S2, S3, S4) installed in the seat portion , the footrest portions , the backrest portion , and the armrest portions , or the command input start time detected by the command start time detecting unit is a simultaneous input point in time at which at least two or more of the pressure signals are simultaneously input. <EOS>
