Abstract
Reading text on electronic device displays can be difficult in varying ambient light conditions, particularly for users with age-related vision changes. Current solutions require manual font size adjustments, which are static, cumbersome, and separate from automatic brightness controls. This disclosure describes a method for adjusting the font size on a display in response to changing conditions, without requiring explicit user interaction. For example, an ambient light sensor may measure surrounding light levels, and user-specific data, such as age and/or a vision quality rating, can be optionally provided. An algorithm uses these inputs to determine an appropriate font size in real time, using a lookup table, a mathematical function, or another suitable mechanism. This method improves readability and accessibility for users of various types of devices by automatically personalizing font size based on both the user’s environment and individual visual needs. In this way, the technology may reduce eye strain, enhance user comfort, and facilitate the reading experience for a user across various applications and devices.
