Posters and drawings on the walls of primary health centers in India. If you want to get an idea of the seriousness of the matter to educate and treat the local population, you can have a look at the comparison of top 10 causes of death between the developed and developing countries.
Can you design a poster so convincing that the beholder would change the attitude, or get motivated for proper treament or prevention? I am no graphic designer, but this presents a good challenge for those of you who are.
on a different note: my new team, Nokia Research Center India worked on a mobile service pilot called Health Radar, a reporting system for malaria outbreaks in 2009. this is no graphic design work, but it dealt with how we can change the existing practices of information dissemination and assimilation. changing the existing and forming new habits are the most challenging part of making the new practice work, which is to happen to various people involved throughout the whole process. in the next decade or so we hope to see the top 10 causes of death list in the developing countries will see a dramatic change.
