What are the performance requirements of a mouse?

The performance requirements of a mouse typically include sensitivity (measured in DPI, or dots per inch), which affects cursor precision; polling rate, which determines how often the mouse reports its position to the computer; and ergonomics, influencing comfort during prolonged use. Additionally, a mouse should have a reliable connection (wired or wireless) and responsive buttons for accurate input. Durability and build quality are also important to ensure longevity under regular use.
