Head-mounted display with vibration motor for display image correction
A recently granted patent (Publication Number: US11887281B2) discloses an innovative information processing device integrated into a head-mounted display. The device includes processing circuitry that acquires measurement values from a motion sensor within the display, generates display images based on these values, and corrects the measurements during vibration periods. The correction process involves removing vibration frequency components from the measurement waveform, ensuring accurate data processing. Additionally, the device can correct images from external sources and perform smoothing processes on measurement waveforms during vibration periods, enhancing the overall user experience.
Moreover, the patent extends to an image displaying method and a non-transitory computer-readable storage medium storing instructions for executing the method. The method involves acquiring measurement values from the motion sensor, generating display images, displaying them on a panel, and vibrating a motor within the display to correspond with the image contents. The method also includes correcting measurement values during vibration periods by removing vibration frequency components. Furthermore, the method allows for image correction from external sources, waveform smoothing during vibration, and adding reverse-phase waveforms to enhance the user experience. This innovative technology aims to improve the accuracy and quality of display images in head-mounted devices, offering users a more immersive and seamless visual experience.
