As many People living in the danger of natural disasters are not wealthy, they can not afford expensive early warning systems. But even in poor regions many people own a mobile phone. Therefore Pixoguard is an early warning system for mobile devices. Since these mobile phones are often very old the application requirements should be as low as possible to ensure the application can be run on many devices. The aim was to ensure that a resolution of only 128 by 128 pixels is enough to communicate complex information.
Also the colors were reduced to only 11 tones to save phone memory and run the application on a large range of cellphones. Cohesive pixel animations help to explain advices and warnings and a simple cursor up; down; left; right navigation provides maximum device compatibility.
