AI Technical Summary
Existing digital display devices fail to dynamically adjust image output to accommodate individual user needs, particularly for correcting presbyopia, leading to suboptimal visual acuity for users at varying distances.
A system comprising a distance sensor, central processing unit, and image optimization algorithm that processes user parameters and distance data to adapt image output in real-time for optimal visual acuity.
Enables dynamic pixel-based correction of presbyopia by adjusting display images based on user distance and vision profiles, enhancing visual acuity for users with presbyopia.

Abstract
Description
Regarding Fig. 1 (The block diagram): "Fig. 1 shows a functional block diagram of the arrangement (100) according to the invention. The arrangement comprises a distance sensor (10) configured to detect the distance between a user and the display device (50). The determined distance data are transmitted to the central processing unit (20). In parallel, the processing unit (20) retrieves specific user parameters from the memory module for vision profiles (30). The integrated image optimization algorithm (40) processes this data in real time to adapt the image output to the individual needs of the user." Regarding Fig. 2 (interaction and algorithm): "Fig. 2 illustrates the technical interaction between the user (1) and the terminal device (3). Here, the measured distance (5) is represented as a variable input value for the control algorithm. The schematic representation of the algorithm clarifies the decision-making process: Based on the user profile (1) and the current distance, a correction factor is calculated, which directly modifies the display on the screen (3) to ensure optimal visual acuity."
