PDAs(Personal Digital Assistants), one of the typical mobile devices, are examined in this study to identify the factors affecting their usability. This study focuses on the menu design of PDAs. Three factors including menu extension method, menu structure, and screen orientation were manipulated in a usability experiment. Task completion times, error rates, and degree of subjective satisfaction were measured. Guidelines for designing a PDA menu are proposed based on the experimental results.
