Computers are increasingly being used in settings§away from the desktop. Examples of such systems§include in-vehicle navigation systems, personal§digital assistants, and mobile telephones. Working§with such devices is more complex because the§interactions are typically carried out in conjunction§with other tasks. In addition, the interaction§frequently happens in a non-stationary environment,§i.e., one where the user and the computing device are§moving.§§This book details the investigation whether§completion time in dual-task situations increases,§and whether the activation of on-screen controls§through manual input devices, such as a trackball,§joystick, or touch screen, is unchanged when the§targets are not stationary, and whether the present§models for predicting task completion time still§apply in mobile settings. §§The book presents at a collection of predictive§models for estimating the time it takes to enter data§in a nomadic context. The models provide designers of§mobile devices estimates for mean task completion§time of data input tasks.
