To access interactive systems, blind and visually impaired users can leverage their auditory senses by using non-speech sounds. The current structure of non-speech sounds, however, is geared toward conveying user interface operations (e.g., opening a file) rather than large theme-based information (e.g., a history passage) and, thus, is ill-suited…

Under the umbrella of ubiquitous technologies, many computational artifacts have been designed to enhance the learning experience in physical settings such as classrooms or playgrounds, but few of them focus on aiding orchestration. This paper presents a systematic evaluation of the signal orchestration system (SOS) used by students for a jigsaw…

Learning the Chinese tone system is a major challenge to students of Chinese as a second or foreign language. Part of the problem is that the spoken Chinese syllable presents a complex perceptual input that overlaps tone with segments. This complexity can be addressed through directing attention to the critical features of a component (tone in…
