VRPN is a great library to interface to a lot of input devices commonly used on Virtual Reality applications. From magnetic trackers to datagloves, the list of supported devices is quite long.
So, why do not use a BeagleBoard with a wifi interface as a VRPN server?. That could be very useful as the beagle is pretty small, has low power consumption (so it could run on batteries if needed) and enough CPU power to deal with most of the input devices supported by VRPN.
Our current simple-alpha-version of Wendy is available for download!. Wendy is a simple SDL application used to prototype our Pervasive Widgets (AKA Hermits).
You can download the source code from here. You will need the SDL, SDL_image and SDL_ttf development packages to compile it..
Here is the README for this version 0.1. It has been tried (not really tested) on x86 linux (Ubuntu), BeagleBoard, OMAP Zoom2 and Openmoko Freerunner :)
In our first demonstration introducing our Pervasive Widgets (the HERMITs), we just used the events on our SDL application (Wendy) to detect the user activity. However that is not very convenient if we want to use proper widgets in our devices, so we need to look for a more transparent way to detect user activity.
As we are running an X-server the XScreensaver extensions are a good option for that. What we want is to be able to detect when there is some user activity, but we do not want to get events every time user press a key or touch the screen... we want them only if that didn't happen for a while
Now that the first decade of XXI century is about to finish, it is time to introduce a revolutionary concept to develop during the next one.
The Papermint Design team proudly introduces the HERMITs.
Halloween is the perfect excuse to do something cute.
We can't resist the monster sexappeal side and decide to do something. So we are having a party for kids on this month and a terrrific poster to announce.
If you want to use for your own scary party just download the full size image without the test from the image gallery (here)
Enjoy the sangría!
MUVIMAN is a simple PhotoMint deviation. MUVIMAN extends the idea of real-time image sharing to real-time video sharing. Based on picoFlamingo this system allows to watch different real-time video streams and zoom into any of them.
MUVIMAN is aimed to support security guards on museums or offices allowing them to check in advance nearby video sources to increase their situation awareness.
We prepared a very simple concept demonstration and put it on a video.
Yesterday we announced our new project: PhotoMint. We think this is a nice project specially suited for our OMAP ZoomII and a interesting way to get us into the OMAP DSP world that we have not tried yet.
One of the most interesting features in the new picoFlamingo ("The Cracking Egg") is the possibility to dynamically update slides. In order to illustrate this feature we had written this clock demonstration. It looks like this:
As you can imagine the digital clock in the middle of the screen will update every sec. The best thing is that this demo is almost trivial using the new
Our first try to put everything in a case. Still needs lot of work but it's a beginning. For a final version we will need to unsolder some connectors and build a small power supply to be able to use just one power source for everything
And this is how it will look like with the picoDLP on top, before adding all the pico cabling. We also build a simpler case for our old B6.
Check this video showing the new main features included in the next picoFlamingo version, "The Cracking Egg". What you see on that video is a work in progress version and there is a lot of room for improvement.
Keep reading for the details...
We announced this some time ago, and actually, the first draft was ready at some time in April, however it has been difficult to get time for reviewing it. It is far from being complete, and will need a couple of updates, but it is an start.
Let's first introduce CP.
CP stands for Cool Project... and what's that?. Well, we are having lots of ideas and not too much time so we are putting them here and, maybe, somebody else will implement them sooner than us, or maybe they have already been implemented and we are not aware of that. In the next weeks we will be telling you about these CPs and hopefully some of you will bring them to live or will warn us about something already done.
Let's go for this Magic Frame CP!
This is our next step towards a fully portable picoFlamingo: Speech Recognition. This new feature makes the remote control device optional so, only the picoFlamingo box (will come at some point) is all you
need to make a presentation at any time in any place.
For speech recognition we are using Julius. A very nice tool that seems quite stable and powerful. Check out this video demonstration.
Finally we've some time to start working with the OMAP Zoom 2 and you can check the results in this video.
