What is a microportal?• A microportal is a small version of a portal designed to
run on mobile devices
• A portal is a web site hosted with portal software that allows for:
• Aggregation of different back end systems, processes or websites brought together via a single portal page.
• It commonly provides personalisation of content
• And hosts the presentation layer of information systems e.g. portlets.

Why do we need a microportal?• Mobile devices have become truly
ubiquitous with 1.52 billion users in September, 2004
• A microportal can take advantage of this unprecedented opportunity to present learning material
• Learning content can be aggregated from different websites, back-end syastems, personalised, and a single sign-on used

The design criteria?• The software must be adaptable
• The software must be extensible
• The software must be ‘intelligent’
• Must render well on disparate devices

What are the design considerations?
• A resource allocation problem in which the utility value of the content must be maximised subject to some constraints
• Considerations for calculating the utility value are:
• Informational content
• Cost
• Design metrics
• Relevance

Mobile devices used• Nokia Communicator 9210 running EPOC32
• Handspring TREO 270 running Palm OS 3.x
• SPV Orange Smart Phone running windows CE
• O2 XDA PDA running Micrsoft Pocket PC 2002
• Palm Tungsten T, running Palm OS 5

Performance evaluation criteria
• Image Rendering
• The the speed of loading a web page
• The ease of content navigation within the microportal
• The overall (albeit subjective) quality of the page.

Discussion - Lessons Learned
• No empirical data was used to compare rendering times
• In terms of overall performance:
– Ericsson P800
– O2 XDA
– Nokia Communicator
– the Palm Tungsten T and the
– SPV Orange Smartphone
– Handspring Treo 270
• Phones with resolutions of 160x160 or less are no good for content adaptation and rendering

Summary
• The unprecedented growth in mobile device
usage has created an opportunity to use mobile
devices for learning.
• Software adapted to different mobile devices
needs to be developed, accessible via a
microportal

Summary
• Adaptable, extensible & intelligent sofware has
been developed for a microportal
• The design considerations and constrainsts have
been discussed.
• Mobile devices hold out a good prospect for
learning via microportals.
