Enhancing Digital Information Awareness. Edition No. 1
VDM Publishing House, May 2009, Pages: 296
Digital information awareness is the process by which
people obtain knowledge about important personal
information stored on their computers. This is
usually provided graphically: when information is
hidden from view it must be summoned to the front and
users are interrupted by the system, disregarding the
costs of the interruption. A solution is to use
speech output to complement the graphics, but its use
invokes anthropomorphic feelings whose cues must be
carefully controlled if the system is to be regarded
as humanized. This book describes the design of a
speech-based assistant nased on a set of intelligent
agents and demonstrates how the content contextually
cues the significance of visually hidden information,
and how the delivery impacts on the social
acceptability of a speaking system, including
attentive interruptions, linguistic variation and
politeness. An empirical study showed that people
felt a degree of rapport with the such a system.
These results led to the abstraction of design
guidelines for speech-based systems that purport to
be humanized in nature. The book is useful to
scholars and professionals concerned with the design
of next-generation user interfaces.
