What are the ergonomic features of a handheld?

Handheld devices often incorporate several ergonomic features to enhance user comfort and reduce strain during prolonged use. These can include a contoured shape that fits the natural grip of the hand, textured surfaces for better traction, and strategically placed buttons or controls that minimize finger extension. Additionally, lightweight materials and balanced weight distribution help prevent fatigue, while adjustable settings for screen brightness and orientation can reduce eye strain.
