Hitachi had ten patents in mobile during Q2 2024. Hitachi Ltd filed a patent for a head-mounted display (HMD) operated by gesture control, with features such as detecting gesture operations, acquiring position information, and enabling communication between multiple HMDs to prevent overlapping operating spaces. Another patent involves a smartphone with touch and proximity sensors that detect user interaction, allowing for the creation of display information with operating-object images superimposed on existing content, which can be output to an external display.

Application: Head-mounted display (Patent ID: US20240201791A1)
The patent filed by Hitachi Ltd. describes a head-mounted display (HMD) that operates based on gesture commands from a user. The HMD includes components such as a distance image acquisition unit, position information acquisition unit, and communication unit to enable interaction with another HMD. A control unit manages the operating space where user gestures are valid, exchanges position and operating space information with another HMD, and adjusts the operating space to prevent overlap between different HMDs.
The patent's claims detail the specific features of the head-mounted display, including a projector, see-through lens, receiver for position information, communication interface, and controller. The controller is responsible for setting the operating space for user gestures, displaying mixed reality objects, acquiring information from other devices, determining space overlap, and adjusting the operating space accordingly. Additionally, the controller can notify users of limitations in gesture operations, switch operations to a smartphone if necessary, and manage operations related to content selection and viewing initiation or termination. The inclusion of a camera allows for the detection of user gestures, enhancing the overall functionality of the display apparatus.
