An Agent has been detected in the matrix!

An Agent of the Matrix in the Rift

So, as it turns out the Oculus Rift latest SDK and Runtime no longer supports using "extended model" with the Oculus Rift.  Which means we need to update our support for it.  I have started working with LWJGL and some examples.  Above you can see a virtual screen rendered in front of the user in the oculus rift. 


The QA Countdown to Release

Here is a list of the current services in MRL so we can figure out what to QA.

Update: Here's a better preview using MaryTTS

 

Here's a sneak peak at the new WebGUI with ProgramAB and the speech recognition using Google Chrome web speech toolkit.

 


Boston Hack-A-Day meetup

So, I saw on hack-a-day that there was going to be a meetup at the Artist Asylum here in Boston.  I wasn't even aware of any maker spaces around here, so I just had to go check it out.  Awesome times, lots of cool projects, including.. yes..  a hover board... 

 


Gear Motor and the Elbow.. Work In Progress

Ok, So I realize that I'm editing and updating this blog in reverse.. but so be it.  Anyway, here's another little update on the progress with these bevel gear / robot arm joint project.  It moves!  It knows where it moves!  

 

 


Kinect Depth Map rendering in Blender

Well, as we open the gateways to blender from MRL, it seemed like a pretty obvious leap to start trying to render point cloud data from the kinect via OpenNI in blender.  I had the kinect write out to a text file all the x,y,z points.  In a small python script in blender, I loaded that text file and rendered small circles for each point.

Just came across this robot...  It's a bit more agile than the InMoov .  

 


Analog Signals, Software based DSP, Audio processing and more in MRL

Wow. this is a big topic.. I really just want to start the conversation about a few things in MRL.  An open source DSP software library TarsosDSP was identified as a nice library to help implement these DSP like functions.  The library says that it is for audio processing, but lets consider that audio processing is just analog processing.  Arduino analog inputs are definitely analog and should be able to be pumped into any self respecting DSP library.


How many blobs do you see?

New OpenCV filter  "SimpleBlobDetector" has been added.  It will watch a video stream and count up the number of blobs that it sees.  

There is no blob tracking, right now, it just tracks all points of interest so long as the new point of interest is more than 10 pixels away from an existing one.  

In the image below, I drew some blobs on a sheet of paper and held it up in front of the camera..  look at that, there are 5 blobs! 

 


2 Cameras 1 Kinect...

So,  I was able to get 2 cameras (OpenCV) working at the same time as having 1 Kinect (OpenNI) running.

Interestingly enough, comparing the camera images to the kinect image, it seems the kinect has the image reversed on the x axis...
