Previous week has been used to create and holding a presentation of the project in the course skriving, forskning og publisering. In addition, a living document of the end report has be created which can be found here, or you can use the link added in the links section for this blog.
progress report week 9
The last week has been used to write a more detailed description for the project in the course Forsking, skriving og publisering. This description can be found here.
Progress report
Nothing much have been done on the project since last progress report. The only thing that has been done is parsing GPRMC sentences sent from the GPS receiver to the mobile application. This must be done because N70 does not support JSR-179 (Location API). The plan is to make a API similar to JSR-179, but heavily reduced to include only the parts that are needed for this project. In this way, it will be easy to take full advantage of JSR-179 if development of the project will continue after the end of the course.
In addition, a bug was discovered with the bluetooth-service-chooser-GUI, which enables the user to chose the appropriate GPS-service that should be used. The GUI had a cancel command that instead of canceling the search for services made the application hang. This bug happened only when running the application on the mobile and not on the emulator which made the task of finding the bug harder. The problem occurred since the command waited for the service-find-thread to end which never happened.
In the near future, some scenarios of the application will be posted along with use cases. In addition, the following week I will concentrate on writing the project description and making the project specification instead programming.
Progress report
This week the focus has been on connecting my Nokia N70 to my Holux GPSlim 236 using bluetooth and Java. The first task was to find the devices in the proximity of N70 and the services provided by these devices. In order to make the end user experience as good as possible, a GUI with a list of the services was developed. The next task was to open a connection to the service chosen by the user. Currently, the output from the service is only appended to the main form as StringItems.
The next task will be to parse the sentences outputted from the GPS, and extract the necessary information. In addition, some decision must be made to how much of the data from the GPS that is necessary to store and use to represent a jogging route.
Getting started
On Wednesday, I got the devices which the project joggerlogger will be developed for. The mobile phone and the GPS receiver that will be used is Nokia N70 and Holux GPSlim 236.
Prelimenary project plan
A prilimenary plan for the project has been made and it is available here
Tentative project description
The idea is to make an application which enables joggers to log their movement when they are jogging a route. The log can be used to visualize the route on a map along with statistics like number of kilometers and average speed. In addition, the statistics can be compared with previous statistics from the same route, making it possible to see if some improvements have been made.
Another use of the log is to share it with other joggers by uploading it to a central server. Thus, joggers around the world can cooperate with each other and find the best routes. The routes can be placed on a map, enabling joggers to find routes in the area where they live. Furthermore, statistics from jogging the routes can be shared, and used to compare and compete with other joggers. The statistics can also help joggers find a route that is appropriate according to their fitness level and the time available for jogging.

Assignment 2 – Mobile Phones
Give a short overview of the development and deployment of mobile phones and mobile services. Have the mobile markets developed differently in different parts of the world? Use your preferred search engine to find appropriate online sources, and refer to these in the text.
Mobile phones started being used mainly for calling and talking with other people, but it uses has evolved tremendously. The first real change happened with the introduction of Short Message Service (SMS) in the early 90s. SMS enabled people to send text messages to each other instead of talking, and become extremely popular in Europe, Asia and Australia. The second change happened with the introduction of Multimedia Messaging Service (MMS) and incorporation of cameras in mobile phones. MMS addressed limitations of SMS, and enabled people to send pictures and sounds as well as text. As a result, mobile users could share pictures taken with the mobile phone with others. The third change is probably happening now with the introduction of UMTS.
The mobile phone market is big and has had a tremendous growth over the past 10 years. It is especially big in Europe, Japan, Taiwan and Korea, and a great part of the population in those areas has mobile phones. In Norway, for example, there is over one mobile phone per inhabitant. Still, further growth is expected since the mobile phone market is growing in several of the most populated countries in the world. This includes countries like China, India and Brazil.

Give a short overview of how you think mobile phones and mobile services will develop in the next five years.
I think mobile phones will just keep replacing other devices by incorapting these in the phone in such a way that one has only one device to carry around. It will probably include a mp3 player, camera, mobile phone, e-reader, watch, GPS and DVD player.
The mobile phones will also get more powerful along with greater speed for transferring data between devices. These two factors will enable a whole range of services not possible today. I have a hard time picturing what types of services that will be offered. However, I am pretty sure they will become a very important part of our lives.
