The HyperPen Windows driver is software designed to enable and support communication between a tablet or pen input device (such as a graphics tablet or drawing pad) and your Windows computer. It is commonly used with devices like the Aiptek HyperPen series of graphic tablets. The driver allows the tablet and pen to function properly, allowing for pen pressure sensitivity, tilt support, and other functionality in compatible applications such as drawing software (e.g., Adobe Photoshop, Corel Painter).
