Augmented Mirror at InnoCarnival 2012

2012-11-02T23:26:00+08:00

After showcasing Augmented Mirror at SIGGRAPH 2012, it is now on show at InnoCarnival 2012 in Hong Kong Science Park during 3/11 - 11/11!

We’re getting a large publicity this time, including a lot of local newspaper articles:

bbTV interviewed me and the news was once on the front page of Yahoo HK!

Vector Sound Wave Morphing

2009-05-20T06:53:00+08:00

This my my final project for the course “Interactivity I”. For this final project, my aim is to explore the vector nature of sound wave while making a tool to let people create their own waveform which can then be saved for other use.

The waveform in the program consists of 10 control points. The first point and the last point are fixed at zero so that the wave can be looped smoothly to form a sound wave. The controls points can be adjusted by dragging or by using keyboard. The points are assigned with keys labelled near them, which are number keys (+shift to move points up instead of down). I recommend using the keyboard as you may adjust multiple points at the same time (which feels like using multitouch surface 8-) ).

Degrafa is used to construct the wave form. I choose to use cubic bezier curve as it is easier for me to implement the algorithm (with the still-in-beta AdvancedCubicBezier which available via SVN).

The 3D cylinder is made by Flash Player 10’s 3D API. It looks quite nice as similar to landscapes.

Sound is synthesized dynamically in real-time (with some delay… okay? ;-) ). If you hear some “clicks” or “pops”, try to export the sound first by clicking on the export button at the bottom-right corner (it will be in wav format, encoded by the WavEncoder from popforge) .

If you hear nothing, you may try to increase the buffer size or use the export function.

CityU’s Usability Testing Lab

2008-11-08T23:01:00+08:00

Just a few days ago, I went to CityU’s brand new Usability Testing Lab to do usability testing for my assignment. It is located in InnoCentre (Kowloon Tong), on the 5th floor, inside Department of Media and Communication. I searched around InnoCentre for so long since Dr. Andy Chun (Yup, another Andy) forgot to say which room the lab is located…

For the lab, I am a little bit disappointed, since it is actually only a little room. But the Department of Media and Communication is great. There are many other special rooms (or labs) for recording, broadcasting etc. And the technician who guided me through using the equipment is really nice.

The special computer used for usability testing:

My site has been tested two times while I also help testing another group’s web site. What we have got were some heatmaps, eye-tracking videos, and some simple software analysis (interesting areas on pages etc.). I think it seems to be too little data for me, but there were no time and people left to do more testing.

Actually what I am interested is booking the lab for testing games… There was already a XBox 360 located in the room and the technician kept asking us to play… It will be good to let me try testing my forthcoming games, but may be I will never have a chance to come back since the lab is not opened for students normally…

Just finished the Transmedia Exchange Presentation, and I’m on CityU News again~

2008-11-07T20:12:00+08:00

In this morning I have just finished the Transmedia Exchange Presentation with my group-mates. That was just a tiny scale of presentation, which most of the audiences were BScCM students.

There were reporters from COMO (Communications Office of City University of Hong Kong) and CM. We presented in this morning and there is article on CityU home page now… They acted so fast! Below is the link…

It’s time to post some photo of our work!
The photo are taken by ar順, and I got them from her Flickr.

The showcase has finished.

2008-06-20T23:29:00+08:00

Spending nearly a whole week on the showcase resulted a tired body and valuable experience.

Although the showcase has finished, it’s not really the time for rest. There are a few websites need to be done soon…

Our work is in CityU News!

I’m really excited about this! Although I cannot remember that I said those words…

PLAYFUL MEDIA, BScCM Special Interest Group Showcase 2008

2008-06-17T02:11:00+08:00

Yup, the showcase has just begun!
I feel so great that I can participate in the showcase!

Our group’s work is called “Mirage” which is an installation.
It was just completed today (an hour after the showcase began…orz), but the result is quite good.

Photo will be posted in the next few days.

Going to “RIA Tutorial - Java Technology Behind Web 2.0”

2008-06-09T22:37:00+08:00

Sun Technology Campus Demo - Talk1

Today I went to “RIA Tutorial - Java Technology Behind Web 2.0” which is held by Sun in CityU’s Computer Lab. It made me interested when I knew that JavaFX will be demoed in the tutorial.

JavaFX can be compared with Flex and Silverlight which are technologies to develop RIAs. Using both declarative and scripting languages. Everything seemed not too difficult although the syntax is differ from C++ or ActionScript that I use most. But I think I would continue concentrating on Flash and Flex (or even try some haxe…) since JavaFX is still in development and it looks not running fast… fast enough to run games.

The tutorial gave very simple demos of JavaFX and jMaki. You may find them from the link on top.

P.S.. I met K and Marco there! I was worrying if I will be the only BScCM yr1 student who really comes…
