Mobile HCI 2004: Mobile Design and Interaction
O2 Active: enhancing user experience on mobile phones
Anat Amir
a WAP portal plus a Symbian app
[coincidentally, the design was carried out by Iconmobile, the same company I worked with to design Orange's active idle screen]
links to URLs
link to device functions
links to other applications on the device
voice calls
SMS/MMSes
text tickers
wizards
auto-launches, but not on top of stack
access methods:
device toggle key
right idle screen key
icon in app grid
page impressions per unique visitor increased by 25% within the first two months after launch

A Prototype for Remote Vehicle Diagnostics
Jonas Kuschel
How can service technicians get detailed vehicle data when the driver is concerned or when the internal control system has detected an error?
error codes and predefined parameters trasmitted over GPRS
*****
Adaptive Portal Aggregation for Pervasive Client Devices
Gert Kortuem
proposes enhancements to JSR168 portal/portlet spec
a new view called summary mode
shows key status
front page adaptation
automatically update the view depending on context, amount of information
adaptive portal aggregation
context send with HTTP request

Supporting Mobile Applications with Real-Time Visualisation of GPS Availability
Anthony Steed
GPS error changes dynamically over time
if you have a 3D model of the local area then you can calculate a GPS shadow
real time visualisation using live or recorded NMEA strings from GPS
shows that seeing clear sky is not the most important factor
and that GPS availability is *very* locailised in built up areas
doesn't explain/show other GPS effects such as refraction and reflection
the tool can help you tell if your fix is unreliable
[this one is very cool - an old version of hte software is downloadable from his website... I will try to get a copy of the 24 hour visualisation]

Bringing the Office to the Stables
Stefan Wagner
smartfarm
several prototype projects made with PDAs and phones
all failed miserably from a commercial viewpoint
work is highly mobile
farmers highly dependent on PC applications
only use PCs in the office (20-40 min/week)
PC based data accessed through printed paper lists
paper lists more efficient than technology
PC used for more than data input
future work
use SMS to alert, and let farmer print out new paper lists
use barcodes on the paper
pigs fitted with RFID

Comparison of Mobile and Fixed Use of SmartLibrary
Markus Aittola
http://www.rotuaari.net
service shown at last year's conference
been redesigned with web user interface
covers 60000 books in Oulu Uni library
test shows all users find PC version easy, PDA most find it easy, phone most find it hard
