Abstract
A wearable device includes a PCB (Printed Circuit Board), a fan element, a radar module, an IMU (Inertial Measurement Unit), and a processor. The fan element is disposed on the PCB. The radar module is adjacent to the fan element. The radar module detects the rotation state of the fan element, so as to generate a detection signal. The IMU is disposed on the PCB. The IMU measures the movement state of the PCB, so as to generate measurement data. The processor calibrates the measurement data according to the detection signal, so as to output a calibration measurement result.
Claims19
A wearable device, comprising:
- an HMD (Head Mounted Display)
- a PCB (Printed Circuit Board);
- a fan element, disposed on the PCB;
- a radar module, disposed within 10 mm of the fan element, wherein the radar module detects a rotation state of the fan element, so as to generate a detection signal;
- an IMU (Inertial Measurement Unit), disposed on the PCB, wherein the IMU measures a movement state of the PCB, so as to generate a measurement data;
- and
- a processor, calibrating the measurement data according to the detection signal, so as to output a calibration measurement result.
A control method, comprising the steps of:
- providing a PCB, a fan element, a radar module, and an IMU, wherein the fan element and the IMU are disposed on the PCB, and the radar module is within 10 mm of the fan element;
- detecting a rotation state of the fan element via the radar module, so as to generate a detection signal;
- measuring a movement state of the PCB via the IMU, so as to generate a measurement data;
- and
- calibrating the measurement data according to the detection signal, so as to output a calibration measurement result.
