Reality mining

March 18th, 2008

Interesting article about reality mining. Basically it is about collecting “reality information” about people, mainly from their cell phones. For example positioning by GPS, Cell-ID, proximity to hotspots; social networks by analyzing phone logs and bluetooth proximity and so on. This is about the same thing you can do with IYOUIT, but what is explicit in this article is the use of data mining algorithms to analyze the data and factor analysis to find correlations among multiple variables. Using this they can for example “…accurately model the social networks of about 100 MIT students and professors. They could also precisely predict where subjects would meet with members of their networks on any given day of the week”.

This is an aspect to consider for personalizing learning reminders.

Location based services based on Cell-ID

March 14th, 2008

No activity here for a long time, but now it’s time to start blogging again.

Yesterday I found an interesting article about Place-Its, which might be described as mobile post-it notes that are activated on your cell phone when entering/exiting certain locations. The user can add notes and the criteria for activating the notes, such as “when arriving at work”. The positioning is based on GSM location (MCC, MNC, LAC and Cell-ID). This could be very interesting for mLearning, and relates to the concept Context Awareness, and applications such as IYOUIT and the papers written about that.

I will try to get a student to write some application about that, with the addition of a web based interface as well, and with the addition of adding links to reminders. This could be used for getting reminders of what to study in mLearning situations such as when entering the subway station. Python Series 60 is probably the best choice for developing such an application.

Google Docs Presentation tool

September 18th, 2007

google docs has now added a presentation tool, much like PowerPoint, with possibilities of giving presentations over the net with interaction through google talk.

New iPods

September 5th, 2007

Apple just launched new iPods.

The new nano has a screen with a 320×240 pixel resolution, with a price slightly lower than the previous nanos and with more memory. This is very important for mobile learning since the new low-end iPods has a resolution which makes enhanced podcasts created from lecture powerpoints readable.

However, the technically more interesting new iPod is the iPod Touch, basically an iPhone without a phone. The user interface and the screen (480x320px) are similar to iPhones, the ipod has wifi and it also has a Safari web browser. Given the high resolution of the screen and the relatively low price, podcast for education are probably very appealing on this iPod.

Now, let’s just hope that the stupid limitation of not allowing rectangular enhanced podcasts is now removed, and  we have an excellent learning tool!

Enhanced Podcasts – HOWTO KTH

June 4th, 2007

An enhanced podcast in Swedish about how to make and publish enhanced podcasts in the KTH/CSC environment. The podcast assumes version 2.1.3 of ProfCast. The versions in the lab room “Loftet” is as of today an earlier version and differs in some aspects.

MobileHCI 07 – Workshop

May 29th, 2007


MobileHCI 07  – Workshop
MobiMundi: Exploring the Impact
of Current and Emerging Mobile Technologies and Services on Society
Held at the 9th International Conference on
Human Computer Interaction
with Mobile Devices and Services

·    Position Paper Submission: June 30, 2007
·    Results Notification: July 6, 2007
·    Final Submission: TBA (Mid August)
·    Workshop date: September 11, 2007
·    Main Conference: September 11-14, 2007

Mobile information and communication technologies are increasingly
impacting the lives of individuals and are a major factor in helping
re-shape our cultures and societies. Ubiquitous computing and mixed-
reality computing scenarios are becoming commonplace and have a huge
influence in the way in which individuals relate with others and their
surroundings. This workshop will provide the environment for
researchers and developers to explore the impact of existing and
emerging mobile information and communications technologies and
services on society.

Position papers are currently being accepted for review for select
participation in this unique workshop. Topics considered (but not
limited to) are the following:

·    Interdisciplinary perspectives towards mobile interaction (e.g.
Social aspects)
·    Exploring theories which help us understand how mobile technologies
impact our cultures and societies;
·    Exploring the the social-shaping of mobile technologies and
·    Determining how human behavior in mobile contexts and mixed-
realities is measured and evaluated;
·    Examine the possibility/potential of safety issues (e.g., health
effects, security issues);
·    Exploring the impact of mobile gaming and the emergence of a global
youth gaming culture;
·    Exploring the the impact of mobile technologies and services on
youth and children;
·    Discussing the impact of mobile technologies and services on
cultures and communities;
·    Examining ubiquitous gaming and social computing scenarios and its
impact on society;
·    Determining ways in which mobile technologies can amplify and
enhance human cooperation,
·    Investigate the emergence of smart-mobs and mobile ad-hoc social
·    Explore the concept of social presence within virtual and mixed
·    Examine the impact of mobile blogging and citizen journalism;
·    Examine the unintended and imaginative uses of mobile technologies
and services;
·    Examining the negative aspects of mobile technologies and services;
·    Explore the impact of wearable computers on culture and fashion;
·    Discuss the acceptance of wearable computers within social contexts.
·    Explore best practices for Web sites for mobile devices and examine
how this can enhance society;
·    Discuss results from ethnographical and related field studies with
mobile technologies and services;
·    Explore how mobile technologies can enhance group interaction and
·    The future of location-aware interaction;
·    Explore the concept of mobility, work environments and other mobile

The MobiMundi Workshop (Mobile World) will be held on the 11th of
September 2007.  To encourage interaction, our workshop will be
limited to 30 participants and will be highly interactive and will
allow for ample time for general discussion.

The format of the workshop will be a full-day event in which the
presentation and discussion of thoughtfully written positions papers
will be conducted.  The workshop agenda will be determined by the
organizing committee and will include a panel discussion with invited
speakers who are active researchers in the field of mobile
computing.  The Agenda will be published on the workshop website:

The primary aim of this workshop is to provide the environment for
researchers and developers to explore the impact of existing and
emerging mobile information and communications technologies and
services on society. The goal of this workshop is to assist the
workshop participants to gain a broader understanding on how their
research and development impacts society in order to help improve
current and emerging mobile human computer interaction scenarios and

Authors are invited to submit position statements (max. 2 pages).
All submitted position statements will be peer-reviewed by members of
workshop committee for originality, significance, clarity and quality.

Papers will be published online as MobileHCI07 workshop proceedings.
Authors of papers presented in the Workshop will also be invited to
enhanced versions of their papers for potential publication in a
special issue of a relevant journal.

Podcast about podcasts in education

May 28th, 2007

A presentation by me about using podcasts in education (in Swedish). The enhanced podcast file (m4a) can be viewed using QuickTime or iTunes, the 3gp file is suitable for mobile phones (tested on a SonyEricsson P990i), and the pdf file is… well a pdf file.

Google calendar for mobiles

May 25th, 2007

Google has just announced mobile support for Google Calendar. Previously, it was possible to sync your google calendars to your mobile calendar using goosync. However, based on my own experience this is rather shaky, and to sync several calendars you have to use the “pro” service, which costs about 30 euro per year (and which doesn’t work very well for me).

The new google service allows you to see (all) your google calendars through the mobile’s web browser. Just point your mobile web browser to and log in using your regular google account.

In my own reserach, I have found that one of the highers prioritized mobile services for students is mobile access to schedules for their courses, and using this service makes that easy.
