AirPaintÂ allows you to paint in air with your iPhone. It uses the built-in accelerometer to estimate how you move the iPhone when painting a stroke in air and the stroke is then displayed on screen.Â
Inspired by light graffiti, AirPaint brings the concept of long exposure in photography to the iPhone. Light graffiti is a method of capturing light motion in the air using camera's long exposure (see guide). Work by Â lichtfaktorÂ is a great example.Â AirPaint unfortunately offersÂ onlyÂ a small portion of this type of painting by only utilizing iPhone'Â accelerometer. One can't help but feel slightlyÂ disappointedÂ by theÂ limited set ofÂ featuresÂ in this app especially considering the possibilities that exist. One of these could be the ability to create a form of photo collage using the iPhone's camera and air drawing with ability to overlay/position your drawing in space/your photo with scalability and perspective transformation. Another great element that would really make this app exciting is ability to set Z value variable, ie movement in depth/third dimension. One would then be able to set a variable of lets say 2 meters and when you move your iPhone it would reconstruct your graffiti in three dimensions. You could then overlay this onto the photo your earlier had taken. Of course, this is a lot more programing but nevertheless a great opportunity for the app to seriously appeal to all those interested in light graffiti and those that have not tried it because of all the toolsÂ requiredÂ to produce attractive results.
