height="80" width="120" align="left">We've
recently seen a couple of intriguing stories about
research projects involving unexpected uses of
hands. One project uses vortices of air to enable
people to <a
href="http://www.disneyresearch.com/project/aireal/">feel
virtual objects</a> as if they were touching an
actual physical object. Another project transmits
otherwise inaudible sounds from one person to
another just by <a
href="http://www.disneyresearch.com/project/ishin-den-shin/">touching
an ear</a> with a finger. In both cases, the
research comes from The Walt Disney Company, which
might be unexpected until you consider that Disney
is a very big user of technology, both in its
films and in its theme parks. Some of the projects
they are working on in the area of wireless and
mobile computing might someday be useful for
libraries. All links below are to Disney Research.

href="http://www.disneyresearch.com/project/transmit-diversity-for-backscatter-rfid/">Transmit
Diversity for Backscatter RFID</a> "By
adjusting the phase of the signal transmitted
from each reader antenna to cancel the phase
delay of the channel, the signals from each
antenna add constructively at the RF tag; hence,
the power delivered to the RF tag is maximized.
This technology can improve the read range and
reliability for radio frequency RF tags in
applications with time-varying channels - e.g.,
backscatter sensors operating near moving people
or where radio frequency identification (RFID)
tags cannot be confined to a portal."</li>

"Drawbacks of GPS are high battery consumption
and the need for a clear view of the sky, making
it impractical in indoor areas, tree-covered
zones, or similar environments where obstacles
shadow the GPS signals. Approaches using the
cellular network are not reliable and precise
enough. In this project, we develop a station
identity management system that preserves base
station location privacy. The objective is to
allow only authorized parties to obtain the
locations of guests."</li>

Acoustic Data Transmission to Ad-hoc Mobile
Phone Arrays</a> "For example, events in a
movie can trigger additional and assisting
information to appear on a phone's display. This
is particularly attractive when there is no need
for a wireless infrastructure. Avoiding the need
for a dedicated wireless infrastructure, the
movie (or show) can directly interact with
phones in the audience, independently of the
local resources."</li>
