Abstract:

Tangible interfaces, such as keyboards, mice, touch pads, and touch screens,
are widely used in human computer interaction. A common disadvantage with them
is the presence of mechanical or electronic devices at the point of interaction
with the interface. This presentation will start from a brief background
introduction of ubiquitous computing, and then introduce work aimed at
developing new tangible computer interfaces that can be created out of almost
any surface by detecting the vibrations generated by the interaction of a
user's finger with the surface. Various approaches have been investigated in
this work, including the time difference of arrival (TDOA), the location
template matching method, and continuous object tracking. Corresponding
demonstrations will be also presented.
