BeYourOwnDoctor

OLPC – GsoC 2008

Project: Be Your Own Doctor (based on data from Health hardware)

Abstract

Until today there is not a widely used method for the computer to interact with the user based on her/his emotions. While the cost of electronics components decreases, new devices for getting and using human biological signals are developed.

Be Your Own Doctor (BYOD) will make it easy for children to get acquainted with their bodies using data from TeleHealth Hardware of OLPC platform (ECG, GSR, Pulse) and present them in a funny and children-friendly user interface.

Children will be able to have a better understanding of their body functions and explore parameters like their heart rate, galvanic skin response (the sweat in their hands -a clue for anxiety), breath rate while doing different activities.

Additionally, prior to writing BYOD itself, I will write and implement the software that will get the data from the BioSignals devices (if there is not such a software until time of developing). I have already developed a similar hardware for my BSc. thesis. In any case it can be used only sampled data from electronic sources to simulate the bio signal data!

About me

My name is Ioannis Valasakis (tungolcildATgmailDOTcom) and I am from Greece. Right now I am completing my BSc. (Electronics Engineering and Computer Systems - 4th year) thesis which is about a Portable Biomedical Electronics Device. I have developed a battery-powered wireless ECG with physical signal probes that gets physical data (like 3-lead ECG, GSR, Heart Pulse) from the user/patient using embedded AVR processors.

The data are transmitted wirelessly (or serially via RS232) to a central station for further processing. It's low-level code is in C using GCC AVR's compiler, Python on the fronted and also Qt for the GUI in the OS.

Work Experience

2007-2008 (1 year) University of Athens - Media Department (www.media.uoa.gr) Programming - Artistic Supervision I was the core developer (with another one assistant) for a game created in Adobe's Flash for children with special needs. The programming was done in ActionScript 2.0 and the animation/interface in Flash.

2004-2006 (2.5 years - reference letter available if requested) Intracom Defense Electronics (www.intracomdefense.com) Electronic Engineer I started from internship and they offered me to continue because of my merit. I was in the development team on a state-of-the art military communication system, called WISPR.

In the past I was as a project leader in GNU's Greek Translation Team, worked on various open source projects, using Linux and involved in the community since 2000 and compiling a Knoppix clone for Electronics Engineering design.

I know how to speak C (also for embedded AVR processors), Python (also PyGame), Adobe's Flash. I have also some limited experience using Qt framework and C++. I use Linux and Mac, editors like VI or Emacs, Eclipse. I know shell programming and have been developing personal projects like my Remote Home Automation Project which controlled any electronic device by simply sendind a short message (SMS) to a mobile phone in the home base!

As for human languages I speak and write in English, German and Greek (mother language).

Proposal

Affective computing is a modern term which relates, arises or is influenced by emotional phenomena. Emotion is fundamental to human experience and interaction but technology has in great extend ignored it. As a result frustrating user experience is accounted [1]. It's best use -in my personal opinion- is in making people understand their personal health matters and making computer more emotionally-intelligent. Because of OLPC, my hope is that many children will benefit from this approach -and especially children that don't have much experience with technology.

Based on the concept of affective computing, BYOD will help children better understand how their bodies and the associated biological signals work. The software will get data from the TeleHealth Hardware devices (ECG, GSR, Pulse), process and present them in a funny and children-friendly user interface. If there is not such a code for getting the data from the embedding device I can implement such a software in C or Python programming language (I have the experience to complete this, in a very short time).

As there is nothing similar for wide use today (only some software but often poor written or with limited capability because of their use as research tools) I believe that it will have a great benefit for the community in general and for children especially.

Also, it will be a stimulation for more open source projects in OLPC, concerning health awareness, physical data monitoring and/or game development, which will help children understand even better their bodies. An example is a space game where the children by lowering their heart rate could get more points and fewer enemies. Or a Pac-Man clone, in which less ghosts are chasing you while you feel calm, e.t.c.

You can see a similar project with BYOD here: http://vadim.oversigma.com/hhd/hhd.html, although Vadim Gerasimov is utilizing a much simpler approach for showing purposes. My plans are more extended.

Deliverables - Timplane

• Final software in appropriate form
• Code for data acquisition from health hardware or a sample data suite for testing purposes

Based on my experience in industry I believe I can complete this project in the specified time limit (always with the help of a mentor)! That is about two months and a half...:)

Conclusions

Google's program is a very helpful program for the whole community. It helps students familiarize with the concepts of open source software and more importantly with team work.useful software for children. Students also gain knowledge about how a real program works, it's time limits, e.t.c. I hope that with my great enthusiasm and knowledge about the specific topics of Medical Devices, Open Source Programming and Children Gaming I will offer to the children around the world! That's also my hope!
