Evaluation of a Functional Film Attached on Top of a Tablet PC

This paper presents usability evaluation of a functional film named PenFit attached on top of a tablet PC. We compared a tablet PC with PenFit and that without PenFit from the viewpoint of the ease of writing. We considered several measures to evaluate the ease of writing. We propose "how people can write letters neatly (neatness)", "how people can write quickly (speed)" and "how people can write without fatigue (fatigue)" as the measures to evaluate the ease of writing. As a result, it is suggested that the functional film provides the ease of writing.
