The main reason why I bought an iPad is to use it as a multitouch device. My company proposed an interactive installation using multitouch screen for SoBe couple month ago. I had to start making a prototype without a multitouch device because we planned to buy one after the client confirming. It was hard to make a prototype without multitouch screen because multitouch gesture is totally different user experience compared to general interface like a keyboard and a mouse.
iPhone could be a option but it has limitation because of smaller screen size so that it’s hard to control multiple points with detail. In this reason, iPad has ideal screen size and shows great performance.
Memo, an amazing code artist, already made a multitouch remote as iPhone app but there is no iPad version. I also wanted to make my own version so that I can optimize and can control functions as I want. I had a chance to figure out and made a simple prototype finally. It was lucky to make it without any big issue. Here is a video I took today. C++/openframeworks was used. Next step might be making my own multitouch gesture API for c++ and Flash.

This project has couple of special meaning to me. Fist of all, I moved to NYC to do interactive installation jobs and this is the first project here. FB proposed clients installation projects since I joined and finally Pepsi accepted our proposal. Secondly, I learned how our work with simple idea makes people happy and then they make me happy again while staying in Austin for 5 days of SXSW Interactive. You might understand what I mean after looking at photos I took.

Especially we had to focus on how digital tattoos can be looked real because the main idea was ‘Virtually reskin yourself, then fool your friends‘. Users take a tattoo on their skin and send their friends a photo so that they believe it’s real tattoo. So Here is a list of what I did to add tattoos realism.
- Matching the quality of tattoo to user photo. Because the kiosk used a built-in low quality camera and the condition of space wasn’t perfect to take best quality photos so the quality of tattoo was reduced to match quality of them dynamically.
- Multiply Blend mode. It is basically used to overlap a tattoo to skin.
- Tattoo Opacity.
- Contour to skin. This part would be the most great part. The displacement map filter which is a Flash built in feature is mainly used to add skinning tattoo realism. The kiosk application reads pixel values, especially red channel this time, from user photos in runtime and performs a displacement effect on tattoos. By controlling amount of distortion, a tattoo can be not only overlapped as flat as a pancake but also mapped to skin based on user photos .
- Redness Opacity and Thickness.
- Transforming. This allows user to move, rotate, skew and scale a tattoo.
