Human Information Processing and Ubiquitous Computing
Abstract
This keynote speech focuses on the important research developments in Human-Computer
Interaction (HCI) from both technological and human point of view, discussing the
contributions from psychology, design, human factors, and computer science. HCI refers to
the design and implementation of computer systems that people interact with. It has human in
its core but requires the design of interaction of human with computer technology. To design
an appropriate interaction model, one needs to know how humans process information and
especially if there are differences in human information processing architectures from one
person to another. The latest trend in HCI is ubiquitous computing. The term ubiquitous
computing is often used interchangeably by ambient intelligence and pervasive computing. It
refers to the deletion of a desktop and the use of embedded systems so that the technology
becomes invisible to humans while surrounding them anytime and anywhere. The acceptance
of technology is highly dependent on the way we process information. We conducted a
number of experimental studies. Our findings state that there are differences in brain activities
of males and females as well as differences in cognitive processing models.Males and females
use different cognitive architectures for information processing. In this speech we will review
these experimental studies investigating the human factors for the design of ubiquitous
systems, demonstrate the differences between human information processing in the
integration of speech and hand gestures, and discuss where the biggest challenges remain for
the development of multimodal ubiquitous systems.
