Furthermore, if the parameters are supplied to the game machine as parameters, the moving direction and movement of the displayed item can be controlled by the bending angle of the elbow and the bending angle of the shoulder. Although the shoulder sensor 18 is a sensor that detects the inclination, the shoulder sensor 18 is configured by a sensor that detects acceleration, generates an electric signal corresponding to the bending speed of the upper arm (angular velocity of the shoulder), and generates various parameters.

A bus 61 transfers information between blocks.

The above-described hardware configuration is substantially the same as that of a personal computer or a workstation. A tone generation program is installed in a personal computer or a workstation, and an output from various sensors 55 is supplied. It can be a device. In the musical tone generating apparatus shown in FIG. 5, when performing, the CPU 50 detects operation amounts from the various sensors 55 to obtain musical tone control parameters such as key-on / key-off data and tone color parameters. Performance data is generated based on the performance data. The performance data is transmitted to the sound source device 6 via the output interface 59.

Thereby, it is possible to emit a musical tone corresponding to the operation amount of the various sensors 55 mounted on the human body, and it is possible to produce a musical tone reflected on the movement of the human body.

Next, the processing executed when the tone generator shown in FIG. 5 is activated will be described with reference to a flowchart. FIG. 6 is a flowchart of a main process that is steadily executed when the tone generator is activated. When the main process is started, an initial screen displayed on the display 57 is set and the RAM 52 is set. Initial setting processing such as resetting of various buffers and flags is performed (step S1). Next, a panel setting process for setting or changing a tone parameter, which will be described later, is performed (step S).
2). When the panel setting process is completed, a sensor information detection process described below for detecting the operation amounts from the various sensors is performed (step 3). When the sensor information detection process is completed, performance control described later is performed to generate performance data in accordance with the parameters. The process is performed (Step S4). When the parameter control process is completed, an output process for outputting the performance data generated at a predetermined timing to the tone generator 60 is performed (step S5).

In this case, the process waits until the operation panel 58 is operated to select a sensor to which a parameter is to be assigned (step S11). Then, the operation panel 58
Is operated and a sensor selection instruction is issued, the operation panel 58 is further operated to wait until a change parameter to be assigned to the selected sensor is selected (Step S).
12). Here, by operating the operation panel 58 while viewing the display screen of the display 57, for example, a tone parameter for controlling a dark tone from a bright tone or a pitch parameter for controlling a high tone from a low tone is selected. Can be selected, a volume parameter for controlling a large volume from a small volume can be selected, and a reverberation parameter for controlling a large volume of reverberation can be selected. At the time of this selection, a plurality of types of change curves having different modes of change may be prepared for each parameter so that the change curve may be selected.

Next, a setting is made so that the selected parameter is assigned to the selected sensor (step S), and the panel setting process ends. Step S1
If it is determined at 0 that no instruction to change the parameters assigned to the various sensors has been issued, the panel setting process is skipped. By the panel setting process for operating the operation panel 58, the elbow sensor 14, the shoulder sensor 18,
The musical tone parameters to be assigned to the head sensor 31, the wrist sensor 21, and the like, and their change curves can be set arbitrarily.

Next, the sensor information detection process executed in step S3 of the main process will be described with reference to the flowchart shown in FIG. When the sensor information detection process is started, an A signal, which is an operation amount, is detected from the elbow sensor 14 (Step S20). Next, a B signal, which is an operation amount, is detected from the shoulder sensor 18 (Step S21), a C signal, which is an operation amount, is detected from the head sensor 31 (Step S22). A certain D signal is detected (step S23), and the sensor information detection processing ends. Through such sensor information detection processing, the operation amounts of the elbow sensor 14, the shoulder sensor 18, the head sensor 31, and the wrist sensor 21 can be captured as A signals to D signals.

Next, the parameter control process executed in step S4 of the main process will be described with reference to the flowchart shown in FIG. When the parameter control process is started, the elbow sensor 14, the shoulder sensor 18, the head sensor 31,
The A signal to D signal captured from the wrist sensor 21 and the previously captured A signal to D signal are compared, and it is determined whether or not there is a change in the values of both corresponding signals (step S30). . Here, when it is determined that the values of both the current and previous signals have changed, the signal magnitude is determined by referring to the parameter table of the change curve assigned to the sensor corresponding to the changed signal. The corresponding parameter value is set (step S31). Then, performance data is generated based on the newly set parameter value that has changed and the previous parameter value that has not changed, and the parameter control process ends.

If it is determined in step S30 that there is no change in the values of the corresponding signals, the parameter control process is skipped. With such parameter control processing, the elbow sensor 14, the shoulder sensor 18, the head sensor 3
1. It is possible to generate performance data based on changes in the A signal to D signal, which are the operation amounts of the wrist sensor 21. Since the musical tone is generated based on the performance data, the tone color and pitch of the musical tone change each time the operation amount of the various sensors 55 changes, and the musical tone corresponding to the gesture can be emitted. Further, in the above description, the motion detecting attachment 1 is attached to the joint of the human body by the attachment ring and the fastener. However, the present invention is not limited to this. Instead, it may be mounted by various fixing means that can be mounted.
