Description

Hardware Built-in Pointing Transmission Processing Device and Method The present invention relates to a hardware-embedded pointing transmission processing technology, and more specifically, to a hardware-embedded pointing transmission processing device and method capable of providing consistent pointing performance regardless of the operating system (OS) or hardware settings through a pointing transmission function embedded in the hardware. Indirect pointing devices such as the mouse play a crucial role in human-computer interaction, and pointing transfer functions that convert mouse movements into on-screen pointer movements have a significant impact on user experience. However, operating systems provide transfer functions through fixed settings or limited presets, which may fail to meet the diverse requirements of different users. For example, while Windows’ “mouse acceleration” feature significantly impacts the perceived pointer movement speed, this setting may not be suitable for every user's environment or can cause inconvenience. In particular, in environments requiring highly precise pointer control, such as games, the operating system’s default settings can detract from the user experience. Professional gamers, as high-performance users, prefer specific settings that maintain consistent performance rather than relying on these default operating system transfer functions. However, the operating system's default functions apply non-linear acceleration at various speeds, which can lead to inconsistent results. This can be a problem in environments requiring precise manipulation based on muscle memory. To solve this problem, some gamers attempt to control pointer movement solely through hardware settings, but it is still difficult to completely exclude the influence of operating system settings.
