[0038] The accompanying drawings are only for illustrative purposes and should not be construed as a limitation of this patent;

[0039] To better illustrate this embodiment, some components in the accompanying drawings are omitted, enlarged or reduced, which do not represent the dimensions of the actual product;

[0040] For those skilled in the art, it is understandable that some well-known structures and their descriptions in the accompanying drawings may be omitted.

[0041] The technical solutions of the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0042] Embodiment 1

[0043] The embodiment of the present invention provides a game controller, as Figure 1 shown in the figure, which includes a game controller body. The game controller body includes left and right grips, and further includes at least two sensing electrodes, a signal processing circuit and a communication control circuit. Among them, at least two of the sensing electrodes are respectively arranged on the surfaces of the left and right grips of the game controller body. The signal processing circuit is connected to the sensing electrodes. The signal processing circuit converts the electrophysiological signals collected by the sensing electrodes into digital signals and transmits them to the communication control circuit. The communication control circuit generates game control instructions according to the digital signals.

[0044] In this embodiment, the electrophysiological signals of the human body are identified by the induction electrodes and transmitted to the signal processing circuit. There is an electrical connection between the induction electrodes and the input end of the signal processing circuit. Since the measurement object is the potential difference of bioelectrical signals, both hands need to hold two induction electrodes at the same time, and the potential difference between the two induction electrodes is calculated by the subsequent circuit. When only one electrode is held, the signal is invalid.

[0045] After the signal processing circuit appropriately processes the electrophysiological signals, it converts them into digital signals and transmits them to the communication control circuit. After the signal processing circuit receives the input signals from the two induction electrodes, it processes the data. The processing methods include but are not limited to common-mode rejection, drift compensation, filtering, and amplification. Since the effective amplitude of the electrophysiological signals is low, signal amplification is required; since there is generally AC power frequency noise in electrical appliances, in order to ensure that the game controller is connected to wired devices such as game consoles and personal desktop computers through wires and is not interfered by power frequency noise, filtering needs to be performed on the power frequency noise; the processed signals participate in the internal data operations of the circuit; the operation results are transmitted to the communication control circuit via digital signals.

[0046] In a further embodiment, the electrophysiological signals collected by the induction electrodes include heart rate electrical signals, electromyography signals, and body temperature signals.

[0047] Embodiment 2

Among them, the software client runs based on the hardware end, the hardware end includes a display module, the software client is communicatively connected to the game controller, the software client receives the game control instructions generated by the game controller, and the software client completes the specified game actions on the display module according to the game control instructions.

[0049] In a specific embodiment, the software client runs based on the hardware end, the hardware end includes a display module, the hardware end can be a PC end or a mobile phone end, the games controlled by the game controller are displayed in the form of animations or pictures on the display module of the hardware end, and when the game controller sends control instructions to the software client, the software client controls the game pictures displayed on the display module according to the control instructions.

[0050] In a specific embodiment, the game control instructions generated by the game controller and the software client complete the specified game actions on the display module according to the game control instructions, specifically as follows:

[0051] EMG signal activates game actions: When the intensity of the EMG signal generated by the user's grip force obtained by the induction electrode reaches the set value, the communication control circuit recognizes it as an "attack command" and sends a control command of "execute the character attack animation" to the software client. After receiving it, the software client controls the character in the display module on the hardware side to attack and completes the control command of "execute the character attack animation".

[0052] Body temperature change adjusts game difficulty: If the induction electrode obtains that the user's body temperature continues to rise (such as due to tension), the communication control circuit determines that the user is in a high-pressure state and automatically generates a control command of "reduce game difficulty" to adapt to the user's state. After receiving it, the software client controls to reduce the game difficulty in the display module on the hardware side and completes the control command of "reduce game difficulty".

[0053] In a further embodiment, the software client and the game controller are connected by a wired communication connection or a wireless communication connection. Among them, the wired communication connection includes a serial bus connection, a PS / 2 interface connection or an IEEE1394 interface connection, and the wireless communication connection includes a Bluetooth connection, a radio frequency connection, an ultra-wideband connection or an infrared connection.

[0054] This embodiment also provides a feedback method for the game control system, as Figure 3 shown, including the following steps:

[0056] The signal processing circuit converts the electrophysiological signals into digital signals and transmits them to the communication control circuit;

[0057] The communication control circuit generates a game control command according to the digital signal and transmits it to the software client;

[0058] The software client completes the dynamic color feedback, animation shape change and interface element response of the display module according to the game control command.

[0059] In a specific embodiment, the software client completes the dynamic color feedback, animation shape change and interface element response of the display module according to the game control command, which may include:

[0060] Dynamic color feedback: When the induction electrode obtains the user's heart rate signal and the communication control circuit determines that the user's heart rate increases, the communication control circuit generates a control command of "heart rate increase". When the software client receives the control command of "heart rate increase", it gradually changes the background color of the game interface on the display module from blue to red to create a tense atmosphere;

[0061] Animated Shape Change: When the induction electrode acquires an electromyogram signal and the communication control circuit determines that it is in the charging state at this time, the communication control circuit generates a control command of "charging".

[0062] Interface Element Response: When the induction electrode acquires the user's body temperature signal and the communication control circuit determines that the user's state is relaxed at this time, the communication control circuit generates a control command of "deep breathing suggestion". When the software client receives the control command of "deep breathing suggestion", a prompt box automatically pops up on the display module, displaying "deep breathing suggestion".

[0066] In a specific embodiment, the load is controlled by the driving circuit.

According to the different parameter change trends of the electrophysiological signal, the different types of driving circuits, and the different types of loads, the user can define the control command and the action generated by the corresponding load in the program.

The drive circuit controls the amplitude of the drive motor to increase by 80% according to the instruction of "amplitude increased to 80%", completing the tactile feedback;

[0075] Vibration feedback: When the user completes a game task, the communication control circuit sends a control instruction of "vibration" to the drive circuit.

[0077] Sound prompt: The communication control circuit monitors the user's heart rate signal in real time. When it detects that the heart rate value is lower than the preset fatigue threshold (for example: a 15% decrease from the resting heart rate baseline), it sends an instruction of "play preset audio" to the speaker drive circuit to control the speaker to play a preset prompt sound, and at the same time dynamically reduces the game background volume; Through a combined strategy of acoustic feedback and volume adjustment, the user is guided into a rest state.
