Building Sensor Based Apps for iOS update

Last year I build some apps makeing use of sensors build into the iPhone.

This blog post gives an overview of resources I have explored and found helpful as also examples used.

I tried out some sample code and started to experiment with sensors build into the iPhone.

 

  • A first pretty cool example reminded me of the ContextBlogger that Tim once started. Tagging events with timestamp, tags, GPS location. This is basically what you get from TaggedLocations: https://developer.apple.com/library/ios/#samplecode/TaggedLocations/Introduction/Intro.html#//apple_ref/doc/uid/DTS40008914. If you want to try yourself beware you can only deploy stuff to phones and not run them in the simulator as you need the sensor stuff in the hardware, so compile and run will give you an error with the “No architectures to compile for (ARCHS=i386, VALID_ARCHS=armv6 armv7)”.
  • Second one was a Teslameter (Hi Stefaan ;-)) this one gives you the Gyroscope data and visualizes them in a kind of simple trikorder user interfaces. https://developer.apple.com/library/ios/#samplecode/Teslameter/Introduction/Intro.html#//apple_ref/doc/uid/DTS40008931
  • A simple “air level” Wasserwaage is the third one. Interesting in relation to keep balance whilst doing an other activity, so one could use the module in experiments to calm down as in the Air Medic game http://www.airmedicsky1.org/
More example to come, good book is http://programmingiphonesensors.com/
 

OS X Dictionaries for Dutch

So a lot of times I come across the problem that I have to look up a word or check the detailed meaning of a word when reading and writing dutch. 

Most of the time until now I used van Dale widget, which gives you a good solution but I never found a good way to integrate with the existing dictionary in OS X. So now solution found.

On the the website http://mysite.mweb.co.za/residents/clasqm/os-x/extra-dictionaries-for-dict/dutch.html

I found several dictionaries as

From Dutch:

Čeština ➠➠ Nederlands (2.8 MB)

Dansk ➠➠ Nederlands (442KB)

English ➠➠ Nederlands (1.6 MB)

English ➠➠ Nederlands (1.6 MB)

Français ➠➠ Nederlands (2 MB)

Svenska ➠➠ Nederlands (1.3 MB)

 

To Dutch:

Nederlands ➠➠ Čeština (2.5 MB)

Nederlands ➠➠ Dansk (726KB)

Nederlands ➠➠ Deutsch (3.5 MB)

Nederlands ➠➠ English (4.6 MB)

Nederlands ➠➠ English (2.2 MB)

Nederlands ➠➠ Français (3.3 MB)

Nederlands ➠➠ Svenska (1.4 MB)

that you just can download and add to your system folder for dictionaries, after restarting Dictionary.app in OS X you can use these ;-).

UNESCO Mobile Learning Week report published

From 12-16 December 2011 the first mobile leanring week has been held at the UNESCO headquarters in Paris. This week the report has been published. 

The report provides a good overview on the practical challenges for mobile learning for the information society – that is turning increasingly into a mobile information society. This has implications for education and teaching, where not only educational concepts are of relevance but also economical and societal factors have to be considered. Furthermore, it becomes clearer that mobile learning tackles a different set of educational problems than elearning did some 10-15 years ago.

You can download the report from the UNESCO web-site.

Sensors and Biofeedback

We are currently kicking off some cooperation project for the evaluation of bio-sensor feedback for more focused work. I think there are quite some interesting technologies on the horizon in the area of sensors, bio-feedback, and learning and perofrmance support.

When visiting Stanford University I had some talks with Neema Moraveji (http://moraveji.org/) director of the Calming Technology Lab. They do interesting work on breath control, user feedback, and using the state of being calm for more productive and efficient work. I remember the idea of "if you are working with a computer for your body it’s like being attacked all the time".

An interesting aspect is how to design these kind of tools so that the distraction from the main activities is not high. Split attention effects for monitoring your calm status on the one hand and being productive on the other hand. One idea would probably be that by monitoring your state for some time reactivates senses that we had before and that we have just unlearned by every day stress and schooling.

In one of the upcoming experiment we will probably look how we can use the monitoring of breath, skin resistance, and/or heartbeat while answering multiple-choice questions.

Group versus individual analytics – why versus?

Wolfgang’s recent overview of the discussion on perspectives of learning analytics discusses tactics of annonymising “group analytics” for personal use. The main critique of that blog entry is that the common approach to ensure “privacy’ is flattening the data so no individual can get identified. However, this might render the resulting information useless for learning support. Privacy aspects raise certainly ethical issues for educational applications of analytical data. I consider data flattening as a naïve approach for enforcing privacy. 

First of all, the common data flattening approache takes perspective takes a very pessimistic viewpoint that literally everybody is your enemy from whom you should get protected (e.g., because you might get bullied). Of course, the education system is not a friendly environment, but equally not everybody is an enemy. There are social planes that influence individual learners in different ways.

Secondly, privacy is tightly coupled to personal perception: everybody draws the line between private and public differently and what is considered private is quite fragmented rather than a homogeneous space. The aspect of fragmentation has been quite nicely addressed by Google plus, which makes a difference between the “all private” or “all public” dichtomy of prior social network applications. This fragmentation is further extended by individual choices of what is considered private or public information. 

Thridly, privacy and more particularly data privacy is considered something that has to be produceted. Data privacy is frequently used as a synonm for data protection, for which the provider of an IT system is responsible. However, data protection and data privacy are to very different concepts. I agree that data protection has to be assured by a system provider, but data privacy is a shared responsibility of those who run a system and those who provide the data. Closely related to this problem area is transparency. Learners can only take personal responsibilty of their data/analytics if they are aware what data and analytical approaches are awailable. 

The primary privacy issues that affect learning analytics affect three different problem areas.

  1. Social planes
  2. Personalisation
  3. Transparency

The dimension of social planes for providing tunable perspectives on learning analytics data has been recently discussed in Flores et al. (2011)

Personalisation of information distribution is currently diffusing into a range of social software platforms after Google has introduced the circles in its Plus service. 

Transparency for supporting learning has been covered by Verpoorten et al. (2009) and Glahn (2010).

The main challenge ethical challenge is to integrate these dimensions into an educationally sound framework. This will not be achievable without rethinking and sometimes disrupting popular educational design approaches, paradigms, and organisational policies. 

Self-regulated learning and situation awareness

On the CELSTEC Mobile Media retreat meeting I gave a presentation about the relation between self-regulated learning, reflection, and situation awareness. These concepts are relevant for contextualised informal learning. 

In this presentation I reviewed the Butler & Winne Self-regulation Model and the Endsley Situation Awareness Model. There are some interesting relations that received very little attention in the area of mobile and contextual learning. 

Sex, bombs, and fries for learning

I listened to a very interesting interview with Peter Nowak on innovation in technology and learning. Interestingly, Nowak argues that most innovations that we see today in education and learning are related to high competition in non educational markets, namely the food market, the pornography market, and the military complex. 

His argument is that these volatile markets act as innovators and early adopters that have created and shaped technologies through massive investments. The drivers for this innovation is partly related to performance needs and to the needs of market outreach. Despite negative effects that are related to all of these industries, the high competition and market constraints seem to force them towards seeking technological innovation in order to gain any advantage over their competitors. Then slowly these technologies diffuse towards the mainstream.

Successfull project kick-off

In September and November 2011 two important meetings have happened. On September 5 & 6 the EMuRgency project had its kick-off meeting organized by the Open University of the Netherlands. During the meeting the partners provided a detailed presentation about their expertise, focus in the project and vision. In addition the different activities within the project have been further refined and planned. To “practice what we preach” non-medical experts participated in a short CPR training provided by the partner from the University Hospital in Aachen. Overall, the kick-off has helped all partners to define a common ground, to get to know each other better and to develop a common visiion and concrete workplan for the upcoming months and years.

On November 7 another consortium meeting has happened. This time the focus of the meeting was the administrative and financial management of the EMuRgency meeting. Nadia Thissen from the EMR Stichting has introduced the specifics of the INTERREG IVa programme and consortium members had the opportunity to ask questions. Last but not least we could take a photo of the whole consortium.

 

 

 

 

 

 

 

When did mobile learning start?

Today I came across an interesting posting in a mobile learning forum on XING. The thread started with the question “When did mobile learning really start?”. There was already a posting that claimed that Nokia started the mobile learning idea in 2001. I thought, “wait! 2001 is too late” and started some digging in my references. What I found there was interesting and enlightening. 

To answer the first question we need to understand that mobile learning is NOT about mobile devices.

Mobile learning is about emphasizing aspects of mobility in an educational concept. Besides mobility this includes situatedness,  context dependency, the location of a learning environment etc. 

So when did mobile learning really start. My little research puts the date around 1997. About a year later I had a very enlightening and inspiring discussion with Cathleen Norris and Elliot Soloway in Berlin. Back then they presented their early solutions from HI-CE for “handheld learning”. The core difference to other handhald learning solutions of that time was that they discussed classroom applications that emphasised the mobility of the learners for making the applications valuable. Rather than “handheld devices for learning” they changed the view to “supporting learning on the go with handheld devices”. 

To embrace the difference one has to recall that until around 1997 handheld devices for learning were mostly of the kind of the Little Professor – some were more sophisticated some less. Basically these solutions were relatively small solutions of portable learning systems. With this respect they were very similar to books as the learning content was not affected by the mobility of the learners. Until 1997 mobile and handheld devices were technological extensions of the learning anytime and anywhere metaphore. The HI-CE stuff broke with this perspective. Suddenly learning was dependend on social interactions,movements, locations, and annotations. Instead of enforcing the right time and the right place, the new solutions were empowering learners to create and enrich their spatial learning environments with the new technology. 

My quick research brought another interesting aspect to my attention. In 1998 Rainer Oppermann and Marcus Specht published a concept for a nomadic museum guide. This paper discusses explicitly the application for learning support. The interesting aspect of this paper is that it outlines the first application of Augmented Reality for Learning. This gets clearer with the followup publications from 1999 (1, 2, 3, 4, 5, 6). 

Therefore, the tipping point when solutions for learning changed towards what we now know as “mobile learning”, was around 1997. 

Soon 1700 downloads of Chapter on Mobile and Ubiquitous Learning in L3T

Last year I wrote an article in german to give an overview on mobile and ubiquitous learning developments for the L3T book. Checking out a new visualiation tool if found that the chapter was downloaded nearly 1700 times (1690 to be correct). So I think quite a success. Nice work done together with Martin Ebner from Graz.

So if you speak german and want to read some overview and starting point for mobile and ubiquitous learning get the chapter here:
