SeeSaw is a participated interactive installation.

The aim of this work is reflection of human communication through interaction between human and computer.


The installation is comprised of PC, monitor, webcam, tripod, table, white wall, and runway for spectator’s interaction. Below is about the setting of this work.


[ The Algorithm of my project ]

1. Motion recognition for catching emotional action

2. Distance recognition between spectator and computer



[The first setting and testing]

Test program and test setting using numbers


Runway test


[The Fixed setting]


 [Spectator’s instruction]




[Useful programming languages]  


Visual C++

From Wikipedia, the free encyclopediaJump to: navigation, search

 For Visual C#, see Microsoft Visual C Sharp.

Microsoft Visual C++ (often abbreviated as MSVC) is a commercial integrated development environment (IDE) product engineered by Microsoft for the C, C++, and C++/CLI programming languages. It has tools for developing and debugging C++ code, especially code written for the Microsoft Windows API, the DirectX API, and the Microsoft .NET Framework.

OpenCV is an open source computer vision library originally developed by Intel. It is free for commercial and research use under a BSD license. The library is cross-platform, and runs on Mac OS X, Windows and Linux. It focuses mainly on real-time image processing, as such, if it finds Intel’s Integrated Performance Primitives (IPP) on the system, it will use these commercial optimized routines to accelerate itself.


From   robotik.inflomatik.info/other/robocup/doc/obj…



The OpenGL® API (Application Programming Interface) began as an initiative by SGI to create a single, vendor-independent API for the development of 2D and 3D graphics applications. Prior to the introduction of OpenGL, many hardware vendors had different graphics libraries. This situation made it expensive for software developers to support versions of their applications on multiple hardware platforms, and it made porting of applications from one hardware platform to another very time-consuming and difficult. SGI saw the lack of a standard graphics API as an inhibitor to the growth of the 3D marketplace and decided to lead an industry group in creating such a standard.

This is a work control indication for an administrator of SeeSaw installation If you have any problem, please let me know. Thank you.


[When you open the work]

1. Push the power button, and turn on the computer.

2. Insert password “*****”

3. Check condition of tripod, webcam, and cable

4.1. Open “****” folder, and double click “*****”

4.2. Open “***” folder, and double click “******”

5.1. Insert “step number: 10” and “random variable: 10” to the command window

5.2. Insert “step number: 10” to the command window

6. Enter

7. Arrange every window according to the sample picture

8. See the work for around 1 minute to confirm working well


[When the work stopped]

1. Press “Esc” of keyboard, and then the work is shut down

2. If the work doesn’t shut down, push “X” button of each window to shut down.

3. If warning message box pop up, just push close button.


[When you want to close the work]

1. Press “Esc” of keyboard, and then the work is shut down

2. If the work doesn’t shut down, push “X” button of each window to shut down.

3. If warning message box pop up, just push “abort” button.

4. Press “shut down” of  PC(below and left side on the monitor) to shut down PC

5. Turn off electricity



This is a risk assessment 

Is the work, if free standing, liable to topple? Yes


 This work is comprised with 1 PC, 1 monitor, 1 tripod, 1webcam, and cable. The PC will be under the desk safely, and the monitor will be on the desk safely as well. The only concern of this work is webcam and tripod. The webcam will be attached on the top of tripod. The tripod’s height is around 1m. That will be standing by itself on the floor. The position is not pedestrian path, but I will mark the tripod’s position for easy recognition. Moreover, the tripod and cable between webcam and PC will be attached to the floor safely using tape. Because if the cable would be in the air, someone could be hung on the cable. And also I will mark some indications for pedestrian path on the floor.  



Contribution for final show


1. Catalogue

I volunteered catalogue work for our final show. I and Dan have tried to contribute to the work for several months, but we couldn’t contribute, because leader of publication (catalogue) determined to design by her.





2. Set up Week


I worked to build show for set up week. Although I had hard time of pain because of my health condition, I could work for show with others, and I am very proud that.
