A brain-Computer interface (BCI), also known as brain-machine interface (BMI), utilizes neurophysiological correlates of voluntary cognitive tasks to facilitate direct communication between human brain and computing devices without the involvement of neuro-muscular pathways. This emerging research area has the potential to contribute significantly to enhancing the accessibility of ICT systems f...

Pen Computers: Dream and Reality \Pen computers" [4] oer an interesting alternative to paper. One can write directly on a LDC (Liquid Crystal Display) screen with a stylus or \pen". The screen has an invisible sensitive matrix which records the position of the pen on the surface. The trajectory of the pen appears almost instantaneously on the screen giving the illusion of ink (\electronic ink")...

In 1997, Brian Shackel published the article ‘‘Human–Computer Interaction – Whence and Whither?” In this early foray into historical reflection on the field, past work is covered with a focus on identifying European contributions, issues of particular contemporary interest are explored, and a set of 10-year predictions are offered. In this essay, from a vantage-point of an additional decade of ...

For most computer systems, even virtual reality systems, sensing techniques are a means of getting input directly from the user. However, wearable sensors and computers offer a unique opportunity to redirect sensing technology toward recovering more general user context. Wearable computers have the potential to “see” as the user sees, “hear” as the user hears, and experience the life of the use...
