Patent granted for head-mounted display apparatus with object detection
A recently granted patent (Publication Number: US11886636B2) describes a head-mounted display apparatus that aims to enhance user safety and attention management. The apparatus includes a display unit that shows an outside scene with target objects, a line-of-sight detection unit, a time calculation unit, and a determination unit. The system calculates the time required for target objects to reach the user and assesses the risk level associated with each object. Based on the user's line of sight and the calculated risk levels, the display unit prioritizes showing images related to the target objects with higher attention levels. Additionally, the apparatus incorporates features such as distance detection, focus time monitoring, temperature sensing, and motion detection to further refine the attention management process.
Furthermore, the patent also outlines a method for controlling the head-mounted display apparatus. The method involves acquiring information about target objects, detecting the user's line of sight, calculating the time for objects to reach the user, determining the risk levels of the objects, and displaying images based on attention levels. By integrating these functionalities, the apparatus aims to optimize user attention allocation and enhance situational awareness. The system's ability to dynamically adjust displayed content based on real-time data and user interactions underscores its potential utility in various applications requiring efficient attention management and risk assessment.
