Also known as pervasive computing, ubiquitous computing explores advanced
mobile computing where small devices interact with computers embedded in your
home, office, or places you travel. My work focused on integration of digital
appliances and computing infrastructure:

Ubimedia: Hypermedia in a Ubiquitous
[just an interesting concept, not a project]
- What is Ubimedia?:
- Ubimedia is the concept of linking a combination of information elements,
physical objects, events, and properties (linking physical and digital artifacts)
and using these links to access related information elements or physical
objects. (Based on the hypermedia definition on http://www.cs.njit.edu/~bieber/pub/cs-encyclopedia/hypertext.html)
- Ubimedia is a style of building systems for creating, organising, structuring,
and accessing information around a network of multimedia nodes, physical
objects (including people, places and the things in those places) connected
together by links, including both electronic hyperlinks and physical
hyperlinks. (Based on the hypermedia definition on http://aetos.it.teithe.gr/~cs1msa/Hypermedia/hyp0.html)

- Abstract: In this position paper we describe
an emerging area of research that we believe will have significant impact
in the areas of personal mobility and digital media. Our term for this research
area is "ubimedia", a concatenation of 'ubiquitous computing',
and 'physically-linked hypermedia'. We note that the structure of media is
evolving from standalone media objects (photographs, audio tracks, books)
to collections of semantically related media objects connected by hyperlinks.
These hyperlinks may bridge digital and physical objects as well, thus the
term 'physically-linked hypermedia'. Also, we observe that the rapid advance
of computing and communication technologies into the realm of everyday life
is enabling ubiquitous computing ('ubicomp'), widely thought to be one of
the next major waves of computing. Ubimedia research seeks to understand
how to design ubicomp systems to support interconnected physical and digital
media. 4 Pages

The Internet touches many people's lives today, but the profound impact comes
when the web reaches out past our desks and beyond our personal computers.
With ubiquitous digital communications and computing, the web will connect
to our daily lives transforming how we work and play. We are on the threshold
of this transformation.
Walk through an electronics store today. You'll see many small digital devices,
like cameras, audio recorders, telephones and small-screen output devices.
Now imagine all these devices online, all the time, and backed up by a system
of programs running on the Internet that coordinate the devices and their users.
Not only is this possible but it is also exactly what is already being developed.
All we have do to is to pull the parts together.
Let's imagine how people will use these small computing devices combined
with a pervasive network. We will need a flexible software system to coordinate
the devices. Let's build such a system, keeping it simple and insuring it is

How to Run the Web Backwards.
The World-Wide Web combines cross-platform text and image viewing with
hyperlinking. This creates an information "fan-out" where one
document leads to others with simple "link". That's all the web
really does. But the impact of this simple innovation has been phenomenal.
Can we create a similarly interesting system if we combine simple cross-platform
data input with information "fan-in"? I believe the answer is "yes":
if we "run the web backwards" we can build a system to support
digital information appliances to create information in exciting new ways.
Based User Interfaces for Digital Handheld Appliances
At the intersection of ADS described
above and and Cooltown described below is a web-based front end for data
input to services. The solution I am working towards uses a fill-in form
model for data upload like current web browsers, but the data comes from
devices with no keyboard. In addition the target of the upload will be a
service infrastructure. For this I am interested in using XFORMs in cameras
with a SOAP (aka XMLP) based submission protocol.

is the Multipurpose Internet Mail Extensions, a historic mechanism for
defining email attachments and later HTTP content. DIME is the Direct Internet
Message Encapsulation format a recent proposed format that partly overlaps
MIME. In this report I compare this two formats focusing primarily on their
use for combining XML and non-XML data into complex messages

- Shows that frameworks that hide the distinction between local and remote
objects are inherently unreliable
- We argue that objects that interact in a distributed system need to
be dealt with in ways that are intrinsically different from objects that
in a single address space. These differences are required because distributed
systems require that the programmer be aware of latency, have a different
model of memory access, and take into account issues of concurrency and partial
failure. We look at a number of distributed systems that have attempted to
paper over the distinction between local...[A

- Software Upgrade In Ubiquitous Computing
- Adequate approaches for component upgrade should be required among
the critical properties when designing systems for ubiquity. Ubiquitous
computing creates new challenges for upgrade. To illustrate the challenges
I begin a list of the historically successful strategies for systems
of large scale deployment and their critical ingredients for success.
Then I consider the impact of ubiquitous computing on these strategies
and I examine the impact of upgrade on the practical viability of two
proposed ubiquitous computing systems. This gives us starting point for
understanding an important aspect of realistic ubiquitous computing.
