Development of Educational Applications for Smartphones
Cell phones are one of most ubiquitous portable technology devices available. New services are added almost every day and cellular telephony became a bright example of co-evolution of human societies and new information technology.
This paper presents a study of using this widely available platform for educational purposes, specifically for digital signal and image processing (DSP/DIP) education. While cell phones are already used for different educational purposes they were not used for DSP and DIP which are fundamental disciplines in electrical and computer engineering.
The following learning and technology goals are addressed. (1) An educational software toolbox for cell-phones is developed. Image, voice and audio samples can be taken using phone's camera, microphone or downloading. The idea is to link engineering concepts with everyday experiences at any place and any time. The toolbox has a handy user interface and students can download and install it on their phones for applying various built-in DSP/DIP algorithms and visualizing results.
Students can learn simple DSP/DIP concepts without implementing their own algorithms. (2) Students can develop their own applications for cell phones using software development tools for mobile OS, thus learning topics which are normally not covered by conventional software development courses. The applications can be installed on so-called smart phones which allow application download. (3) The toolbox also allows communication of information with a centralized server for assessment in distributed learning environments.
Thus the presented toolbox provides an opportunity to use typical cell-phone data for educational purposes at any place, at any time, and in distributed environments. The idea of developing a cell phone based educational toolbox for DSP/DIP is motivated by recent studies and polls which indicate a wide acceptance of this platform by student constituency.
1. Introduction Our motivation is based on the current popularity of cell-phone platforms and projected technology advances of mobile hardware and software. Mobile phones are highly popular all over the world. The current trend in mobile technology indicates that the tasks achievable by mobile handsets will soon exceed our imagination. Mobile phone sales worldwide are soaring and in 2004, there were more than 1.5 billion mobile phone users worldwide. This number reached 2 billion by end 2005 fuelled by strong demand from developing economies in Asia and Latin America.
Modern mobile phones are some of the most advanced and technologically complex devices that people use on a daily basis. They are equipped with cameras that can capture still images and also streaming video with reasonable resolution. These phones are also equipped with software
