Andreas Spanias is Professor in the School of Electrical, Computer, and Energy Engineering at Arizona State University (ASU). He is also the founder and director of the SenSIP center and industry consortium (NSF I/UCRC). His research interests are in the areas of adaptive signal processing, speech processing, and audio sensing. He and his student team developed the computer simulation software Java-DSP (J-DSP - ISBN 0-9724984-0-0). He is author of two text books: Audio Processing and Coding by Wiley and DSP; An Interactive Approach. He served as Associate Editor of the IEEE Transactions on Signal Processing and as General Co-chair of IEEE ICASSP-99. He also served as the IEEE Signal Processing Vice-President for Conferences. Andreas Spanias is co-recipient of the 2002 IEEE Donald G. Fink paper prize award and was elected Fellow of the IEEE in 2003. He served as Distinguished Lecturer for the IEEE Signal Processing Society in 2004.

Abstract

iPhone/iPad Based Interactive Laboratory for Signal Processing in Mobile DevicesWith today's rapid development in mobile technology, wireless devices such as the AppleiPhone, the iPod touch and the iPad have become a popular platform for education. Theiradvanced multi-touch interface and improved processing power can also be exploited forengineering and STEM education demonstrations. In addition, as normal computing moves fromthe desktop to handhelds, the potential to encourage students into science and engineering is veryreal. This paper presents the design and implementation of a portable interactive signalprocessing simulation software operating on the iPad/iPhone platform. The online object-oriented iPad/iPhone software is called i-JDSP and is based on the award winning Java-DSP (J-DSP) concept. J-DSP is an on-line laboratory previously developed from the ground up in auniversity environment primarily for education and research. This i-JDSP iPad/iPhoneenvironment (soon-to-be a formal iPad/iPhone application) is implemented in Objective-C and Cas a native Cocoa Touch application that can be run on any iOS device. i-JDSP offers basicsignal processing simulation functions such as FFT, filtering, frequency response on the newcompact and convenient iPhone/iPad graphical user interface (GUI) and provides a verycompelling multi-touch programming experience. All simulations can be visually established byforming interactive block diagrams through multi-touch and drag-and-drop. The iPad/iPhoneplatform is very attractive and we expect that this new environment will expand the communityof student and faculty users. We also expect that these practices will become exemplary forseveral STEM areas. The software is at an alpha-stage and will be released as beta version byDecember 2010. We plan to disseminate the software in our classes and specifically in the DSPand Signals and Systems classes at our university. We will create and monitor a community ofstudent users. We will create specific online laboratories and exercises based on this platform.Preliminary results including performance analysis and student feedback will be discussed indetail in the full paper.
