About my blog

New depth sensors such as the one embedded in the MS Kinect system work in real-time, enabling to create an instant 3D scan of objects. In this project, we are exploring a large-scale installation that demonstrates this by a 400+ array of motors and LEDS. This work includes interaction design, hard-coding and lots of soldering etc. The result will be put on exhibit on various international shows.(Expert: Jouke Verlinden)

Program of demands

Finished writing our program of demands this morning. Now onto the design and the bill of materials!

 

 

Program
of demands – Kinetic mirror
Number Item Explanation
1 Dimensions The
mirror consists of 400 linear motor faders ordered in a widescreen format of
16 by 25. Just looking at the pixels this gives us a moving surface of 100
wide by 64 centimeters high. The frame will encompass this surface and place
the screen at eyeheight. The entire display should be able to fit inside the
trunk of a volvo v70 (1.13 by 2) or inside an aircraft cargo container.
2 Force
handling and stability
The
frame has to be strong enough to handle the worst-case scenario: 400 linear
faders that shoot from one end of their 20 cm guide rail to the other with
200 cm/s
3 Mobility Either
the frame can be taken apart and stored in several cases for transport. Or
the frame itself becomes a single storage unit. 
4 Budget The
entire project has a budget of 9800 euro’s. Subtracting from this the cost of
the linear faders and the PCB’s there remains between 800 and a 1000 euro
available for the frame
5 Ease
of build
We
are on a limited timeframe, so the entire construction would have to take
place in 2 weeks. If possible we are going to use as much off the shelf
material as possible
6 Power
usage
Preliminary
estimation of the power requirements for the entire display comes to about
1500 Watt. This will be delivered by computer power supplies.
7 Acces
to individual parts
In
the optimum case it would be possible to change a single broken fader without
disassembling the entire structure. There also has to be easy acces to the
kinect, power supply and pc inside the frame.
8 Interactie Interaction
between the display and passersby is handled by a combination of the xbox 360
Kinect hooked up to software running on a mac mini. The kinect is capable of
processing a 3D environment between 1.2 and 3.5 meters from the device, it
has a horizontal range of 57 and a vertical range of 43 degrees. Interaction
between the passersby and the mirror increases if the distance between the
scanned person and the mirror becomes smaller.
9 Appearance Should
be clean (white) and futuristic. As little should distract from the mirror as
possible.
10 Weight Heavy
enough to stop the vibrations caused by the linear faders, but light enough
to be transported by car or by air transport.

Exiting stuff ahead!

this project proposal is based on two important technology enablers:

 

  1.  Microsoft’s Kinect – have a look at some of these marvelous movies using the real-time depth scanning. for example YouTube Preview Image
  2. Simple motor faders, e.g. used in professional audio mixing equipment, cf YouTube Preview Image
There are many challenges ahead, software, hardware, electronics and the interactive experience. Let’s roll!
