Today our English-learning app “Word Frequency List 2.0″  is available for download on appstore , We list more than 12000 most important English words by their using frequency in this app, the data is from American National Corpus which includes 4.1 billion English words. The words are divided into 5 sets, each word are more ‘important’ than the one after. This could help user to learn English more efficiently by learning words from the more important ones and avoiding rare used ones.

flipink

Today we submitted the app “flipink” to app store, hopefully it will get approve in one week : ). this is the most complex project I have ever built with my parter Perry, more than 50 thousands lines of code really make me exhausted.

Perry is a great iOS programmer, he did all the database,painting tray UI, file management and SNS sharing modules of this app, I did the 3D UI, openGL accelerated painter and designed the icons, UI, and animations.

collide

Very simple but useful algorithm, it has been used in my golf game, compare to setup a whole 3D physic engine in the game, using this class is far more easier and faster.

the code is wrote in as 2.0

Pose recognition using Microsoft Kinect depth sensor

January 1st, 2011

kintectitle

This month I’m working on build a pose recognition middleware ,the whole setup is based on openCV.

I tried a simple way to do the gesture recognition: first use harr-like feature to find the face, then flood fill to get the connected area ,which suppose to be body , then use some sort of  AAM(http://en.wikipedia.org/wiki/Active_appearance_model), ASM (http://en.wikipedia.org/wiki/Active_shape_model) or just simple integral steping model to get the limb’s position and direction.

Golf Game with flash 10.1 api

January 1st, 2011

golfgametitle

I made a Golf Game last month for the company I joined in recently ,this Golf game is based on the new flash 10.1 API, thanks for the enhanced matrix3d class,  my lite 3D flash engine can do more  serious 3D rendering than before.

The movement of the golf ball is calculated real time by a very simple terrain collide algorithm , each time when the colliding happen, it will recalculate the angle of velocity based on the slop of terrain’s colliding point .

I also made a scene edit tool for editing the terrain, plants and physical properties, it’s based on Adobe AIR.
