Minus Board is a sharable whiteboard app for iPad. I built it as a pet-product for myself as I need to communicate with my remote co-workers, I found that it's hard to explain many ideas without sketching, such as software system architecture. Since I cannot find a decent sharable whiteboard app for iPad, I decided to build one. For the whole story behind this project, you can read my article: How I launch a product in few weeks

It can stand for more than 10K online audiences based on some cheap rental dedicated servers. The peak output bandwidth usage once reached 1.5Gbps. It is composed by different sub-systems, including audio streaming servers, website, Flash player, web-based chatroom, mobile apps, client GUI and routine tools. It was written mainly in Python.

Augmented Reality GPS Guidance System is the graduate project for my Bachelor degree of Computer Science. It is a prototype of GPS guidance system with augmented reality concept. It is composed by an embedded system which runs WinCE OS with GPS module, digital compass module and a webcam. It reads lat/lon and direction, then renders corresponding augmented reality road map on the captured image from the webcam. The video demonstrates how it works on a moving cart in campus. Due to the factor 3D rendering is not well supported in that embedded system environment, I also developed a simple software-based 3D road map rendering system. The whole system is written in C++ language with MFC.
