Project proposal: Virtual Flesh

Proposal

Making methodology : Max/Jitter (tracking color), Pysical Computing (PIC, BX24, Basic Stamp)

A few ideas

1. color tracking : tracking the blue spot on a knife and a pork

Images of a virtual flesh(a vrtual fish) is projected on a dish which is used as a screen. Viewers can interact with a image of fish which is the image on the screen with a physical knife and a physical pork which are set aside of the dish. On them there are blue spots and the blue color. And they can be delivered by the real time video. Tracking the signal shows the result image of their action onto viewing screen.

2. Image tracking : image maipulation, pixel by pixel (?)

the idea one can be controlled by the methodoly of image manipulation.

3. Using sensor : Touch sensor or FSR ?

Images of a virtual flesh(a vrtual fish) is projected on a dish which is used as a screen.Viewers can interact with a image of fish which is the image on the screen with a physical knife and a physical pork which are set aside of the dish. On them there are blue spots and the blue color. The pointing spot of the pork and the knife on the dish can be toggled with some kinds of senses and its signals input to micrecontroller and its output represents the reult on the viewing screen.

Working Process

4/25

In the class Jeff recommend Qprox sensor would be useful for this project. Because I worried that if I use touch sensors, the wires make the plate ulgy. So I decided to change the sensor to Qprox. I had to purchase Qprox for 'digikey'. But today is weekend day it is hard to get. What can I do! And I taught from Catherine how to connect Qprox sensor. At first look, it seems very complicate.

Mac has QT310. Mac and I test to make a circuit with Qprox looking at the dacument sheet. In the while, we found that QT310 and QT113 are very different. QT 310 needs 0.47 capacitor and we found that it is hard to get. and the circuit is a little more complicate then QT113. Fortunately I could 4 QT113 from Gabriela and tested it.

Finally I got an Qprox from digikey. But it was a little bit different. If I give a power LED turns on and when I touch it the LED turns off. Jeff told me that becuase of the difference QT 113H and QT113, it has opposite values. QT 113H gives a high value when I touch it. but QT113 gives low value. And if I connect eight Qprox with --capacitor then it interfereing each other and so Jeff also solve the problem with different capacitor and we found the best choice for my project is using 0.0022 capacitor. I tested it and made sure that it got a value more than 400 as its default and if I touch it it changes to 0. So I need to change my code for my new chips.

Using 0.0022 miliFarad capacitor or paralell connection with two 0.001 miliFarad capacitors makes the eight Qprox sensor less sensitive in the circuit. But I found that it was too stable, so it the touch through the plate is not detected with these.. What can be the altenate choice.. I should get a capacitor having middle value between 0.002 mF and 104M (I don't know how big is this). Capacotor has various kind of type. one of them is ceramic type and metalistic type. I don't know what's the difference..

1 mili Farad (or any other unit) is 1/1,000th or .001 times the unit. (10-3)

1 micro = 1/1,000,000 or 0.000 001 times the unit (10-6 )

1 nano = 1/1,000,000,000 or 0.000 000 001 times the unit (10-9)

1 pico = 1/1,000,000,000,000 or 0.000 000 000 001 times the unit (10-12 )

104=0.1mF *10-3

I bought some 0.001 microlFarad capacitors from RadioShack to make 0.0022 microFarad in paralell connection. and I found the fact that 104M is 0.1 MicroFarad. and 103 = 0.01 microFarad is working through plate!!!

But I found another fact that even though I use 103 = 0.01 microFarad it is very hard to control. If I changed one Qprox, it affect the others immediately. So I am still trying to figure it out how to make the eight Qprox sensors stable .
