Clamping force measurement system and method for head-mounted device

A clamping force measurement method for a head-mounted device, applied to a clamping force measurement system for a head-mounted device, wherein the clamping force measurement system for a head-mounted device comprises a pressure sensing module and a measurement module, wherein the measurement module comprises at least two measurement device and at least one gas guide device, wherein each of the at least two measurement device comprises at least one hollow compressible unit, and the each of the at least two measurement device is configured to discharge gas when volume of the each of the at least two measurement device is deformed during extrusion;

• a first end of a gas guide device of the at least one gas guide device is in communication with a measurement device of the at least two measurement devices, and a second end of the gas guide device of the at least one gas guide device is in communication with the pressure sensing module to transmit the gas to the pressure sensing module;
• and the pressure sensing module is configured to determine a clamping force of the head-mounted device according to a pressure value of the gas;
• wherein a clamping space is formed between two of the at least two measuring devices and the clamping space is configured for clamping to the head;
• and the clamping force measurement method comprises:
• acquiring a digital pressure value of a discharged gas when volume of the each of the at least two measurement device is deformed;
• and
• determining the clamping force of the head-mounted device according to the digital pressure value.
