Paul, On Wed, Mar 4, 2009 at 4:29 PM, p...@laptop.org wrote: [resend from subscribed address] last week i announced a daemon that would activate the grab keys on the XO keyboard. a day or two later there was a thread about how it would be nice if the action of the touchpad rotated with the screen (in much the same way that the dpad keys do). since my daemon was already looking at every input event, it seemed a natural place to implement the rotation feature. and after doing that, the name seemed like it should change. so, announcing olpc-kbdshim. source: http://dev.laptop.org/git?p=users/pgf/olpc-kbdshim rpm: http://dev.laptop.org/~pgf/rpms/olpc-kbdshim-1-1.i386.rpm This is great! Scrolling has never been so easy. :) Thanks Brian after installing the rpm you need to fully reboot your laptop to get the plumbing set up properly. the rpm includes a new command olpc-rotate which takes care of all the mechanics of screen and touchpad rotation. since sugar (currently) handles this key binding, the rpm postinstall script patches /usr/share/sugar/shell/view/keyhandler.py so that it invokes os.system(olpc-rotate) _instead_ of its current builtin behavior. separating it out like this makes olpc-kbdshim and olpc-rotate more useful for non-sugar UIs. i wrote the sugar patch so that it won't break if you uninstall the olpc-kbdshim rpm -- sugar will take over the rotate function again. also, though i haven't tried it on today's brand-new sugar 0.84 (good work everyone!), a look at the current keyhandler.py says the patch should still apply correctly. the topic of ebook-mode touchpad usage came up the other day too. while i didn't create any visible UI support for it, the daemon will put the touchpad in and out of ebook-mode (which means, reflecting it on both x and y axes) using olpc-rotate -e/-n please let me know what you think... paul p.s. btw, the daemon isn't really very olpc-specific. i've been running it on my thinkpad all week, in order to get the use of the grab key scrolling. the thinkpad doesn't have Windows keys (which is what the XO grab keys are), but it turns out the blue Fn key in the corner can be used as a modifier, so that plus my trackstick gives 2D scrolling -- it came in very handy for looking at the bootchart images this morning. =- paul fox, p...@laptop.org ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

Re: Panorama activity
On Sat, Oct 11, 2008 at 10:26 PM, Nirav Patel [EMAIL PROTECTED] wrote: My roomate and I wrote an auto-stitching Panorama Activity during the Yahoo Hack Day at CMU yesterday (ended up winning the Hack for Good award). I'll be posting it in the wiki at some point today. It needs a whole lot of polishing, since it was written in 24 hours. I ran into the same problem that Ben did with autowhitebalance and autoexposure. I looked through the ov7670 driver, and it seems changing V4L2_CID_BRIGHTNESS should flip the auto exposure control (AEC) bit in one of the registers. I added support for changing brightness to the camera module in Pygame, but either disabling AEC doesn't work, or it just makes auto gain control and auto white balance work even harder to change the image. Other than that, the stitching seems to work ok. I'm going to pyramidize it at some point to make it faster, and do something to improve the accuracy. The slowness of stitching doesn't effect the user experience much though, because it only stitches after the user is done taking the pictures. So cool -- can't wait to try. The Activity we wrote uses the Flickr API for an upload to Flickr button. I feel that this is the most important part. There is support for saving the stitched images as Journal entries, but it would be wonderful if a kid anywhere in the world could see panoramas taken by other kids elsewhere. Flickr is far from ideal for this. Beyond not really being designed for viewing panoramas, it is currently set up to just upload every picture to my personal Flickr account. My API key, secret key, and an authentication token are prerecorded in the activity, so anyone could potentially use those values to edit existing photos and upload whatever to my Flickr account: http://flickr.com/photos/nrpatel/ Awesome! :-D Maybe one could set up a one-way upload script for this on dev (or some appropriate community-developed-web-services-server-of-the-future)? This script, then, could handle the uploading via flickr API securely. Regards Brian It seems Gigapan doesn't have an upload API. gigapan.org works in Browse on my os767 XO, but panning around an image is pretty slow. Anyone have ideas on this? A better way to Flickr, ideas for designing a new site, getting Gigapan to add an upload API, etc? The other issue we ran into is integrating OLPCGames with pyGTK stuff. We used OLPCGames to take advantage of capturing the images as SDL surfaces, but we also wanted pyGTK to pop up a Dialog box when the user hits Save, asking for a Title, Tags, and a Description of the panorama. We hacked together something that does pop up the box and saves correctly, but fails to ever destroy the box. It then just sits with the box open, preventing the user from using or exiting the Activity. Is it possible to use pyGTK beyond the toolbox while still using OLPCGames?

Correction, this was hit by the Rwandan *core team*, on their first testing of 767+g1g1 activities (7090 failure case was one of the first few things that was tried). We tried it a second time as an experiment in reproducing a bug error, and instead of just the activity crashing it locked up the machine (keyboard and mouse were unresponsive). Searching Trac for the bug and finding 7090 was a good exercise in bug tracker usage :) I imagine students would encounter this bug rather quickly as well, zooming in on their home continent PDF Google maps style. Can we get some attention on that one? Especially if it can be fixed in the activity, I would like to have a new version in place when we try to upgrade Rwanda 8.2.0 later this year.

Non-developers may participate in categories for level design (for our existing physics based games) or help out with graphic design, music creation, sound effect recording, giving tutorials, and writing documentation. Attendees should have some game development experience, but we will be running tutorials to introduce people to all the tools they'll need to make a successful game for the XO. This will include... * Eric Jordan of the Box2D project will be giving a talk on developing physics games with pyBox2D for the OLPC XO. * Nirav Patel, Google Summer of Code student working on vision processing for the XO will describe combining physics and vision processing for interactive games. * Alex Levenson, OLPC summer intern and creator of the x2o physics game will give a remote introduction to level design for his game.

I just started using the SVGSprite class but I kept on getting an error when using it. I realized that in the SVGSprite class a module named 'svg' is imported, AND a local variable is named svg. So when you call svg.render() it tries it on the local variable (which is a string) and then that causess a crash. The fix is easy, change the line at the top of svgsprite.py from: from olpcgames import svg to: from olpcgames import svg as svgModule and then later in the code there is one reference to svg that needs to be changed to svgModule. Basically just a python scope issue, but I don't know who maintains olpcgames so I decided to just send this to devel.

Re: Computer vision on the XO: what it is. what should it be?
Hey Nirav, games, devel! On Tue, Jul 22, 2008 at 10:43 PM, Nirav Patel [EMAIL PROTECTED] wrote: I'm writing computer vision functions for Pygame (available at http://git.n0r.org/?p=pygame-nrp;a=summary ), and I've gotten to the point where I very much need community input on where to go next. Basically, I would like to know what you want to be able to do with the camera on the XO, whether its related to gaming, input, accessibility, education, or anything else. What it can currently do, in overly simplistic terms: 1. Capture images: This is the basis for everything else, but it can be useful on its own too. For example, letting someone take a picture of themselves, let them select their face in the picture, and then crop that and use it as a character in a game. Yes! This would be something *really cool* to be able to build with during the Physics/Game jam that will be held August 29-31 (full announcement coming soon!). I know you likely won't be in Boston for that time, but I hope you and others will participate in this devfest via IRC/Gobby/Audio/Video! This would also be great to use with Box2D (used in Physics activity and available as the pygame/Elements API), which is showing some promise for simple (GUI-tool-based) physics-based game creation. I've also updated the OLPC physics page to reflect this email and portions of the #olpc-physics conversation on this: http://wiki.laptop.org/go/Physics#Physics_and_vision_processing 2. Get the average color: This is useful for picking values to threshold, but you can also switch to YUV or HSV colorspace and find the average brightness of the area. 3. Threshold images: Thresholding is pretty flexible. You can have it select everything within a threshold of a color or everything outside the threshold of a color. You can also threshold between two images. This lets you get a green screen effect, so you can have a person being displayed realtime over a virtual background. 4. Track an object: After thresholding, you can turn the remaining object into a bitmask and get various properties about it like its bounding box, centroid, size in pixels, and angle with respect to the x-axis. You can also test collisions between the mask and masks of virtual objects. They may seem pretty basic and simple, but you can do a lot of things by combining them. For example: 1. Drawing with a real life object: Have the user pick up an object and hold it up so it fills a box being displayed on screen and hit a button. Save the average color within the box. Threshold out just that color, turn it into a bitmask, get the largest connected component, and find the centroid of it. Use that centroid as the coordinates for the on screen paint brush, perhaps also using the saved average color. The user now has the illusion of using the object in hand as a paint brush. Playing with your Paint! vision processing addition is one of the most fun things I've done on the XO. 2. Play pong with your hand: Have the user step out of the field of view of the camera, save the image. Now threshold between the saved image and the images currently being captured. This results in just showing the differences between the two (like the user, who has now stepped back into the field of view). Turn the image into a bitmask and check it for collisions with the bitmask of the ball in pong. Actually, now that I'm thinking about it, I'll probably write this game when I get home.

Generic motion detection: You can do stuff like thresholding between a background and current images, or tracking whether blobs of colors have moved, but neither is a great way of detecting total motion in an image. There are many optical flow algorithms, but finding one that'll run realtime on an XO will be tricky. The other issue is how to present motion to the developer. Perhaps have the function request two images and a list of points on the first image, and return a list of where it guesses the points are now on the second image. 2. Object recognition: You could guess based on the size or color of an object, but there isn't really a way of detecting if what you're holding up is a lime or a pear. There are a lot of really computationally heavy ways of doing object recognition, but there are also some lightweight ways. The one I was considering was using image moments (which I am currently doing to find the centroid and angle of an object), to get basic parameters like the eccentricity and skewness of an object. There is also the Hu set of invariant moments that will give more information about an object, though not really in a human-friendly form. Thus, while I could fairly easily write functions that would drop a dozen of these numbers, I'm not sure anyone would be able to make use of them in an Activity. We had an

The only reason for #7447 is because we haven't put the UI in to enable it. libabiword supports background colors. If the Powers That Be decide that this is an important feature for children it is very easy to implement it.

Does Abiword provide change tracking, so that users can turn author coloring on and off at will? AbiWord has change tracking but my experience with it is that it is more trouble than it's worth. That said, there is a bug in AbiWord-2.6.4 so that if you turn change tracking on all changes in a collaborative document are marked with the same colour. I'd better fix this so that different users get different colours during a collaboration session. Is there some feedback from the field about how kids are finding collaborative writing?

And the only 'real' solutions I have come up with are: 1 - completely separate the activities from the OS in order to help people understand that most activities are NOT supported or maintained by OLPC; they need to be able to upgrade activities as needed and not wait for new releases from OLPC This is one of those steps that makes sense politically, but doesn't really pan out so well in practice. We really *do* need to have maintainability of a subset of activities. It's unfortunately that defining the set we want to 'own' gets people so flustered, but I still think we may find we need to make some form of commitment in this regard. 2 - push for 'school year' releases (fall and spring); where a school will pick a release and use it for the entire school year so we don't have to worry about upgrades in between that time Yup. and, most recently you will hear me pushing for: 3 - Encourage schools to completely reflash (cleaninstall) their laptops each year. At the end of the school year, you save away kids data (hopefully that is done automatically) and you do a cleaninstall of the next year's image; retest all the latest versions of Activities that you want to use; and provide 'clean' laptops to the kids at the start of the next school year. I think this would be a real shame, honestly. It completely tosses out the benefits of the Journal as a structure for ones interactions and created objects. It means I can't incorporate photos that I took over the summer, or last year, into a story I wrote (for instance, even a what I did this summer essay that we've all written at least once). It means I can't go back and look at some math homework I did to refresh myself on how a particular algorithm works. It means I can't create a new etoys project from an experiment I made last year but didn't have time to continue. It means that I lose references to all the friends/groups I've made. It means that my computer is reset to factory state and I have to change my personal preferences all over again. I think we need to find a way to make solid, secure updates without wiping the machines clean each year; otherwise we're contradicting our goals for learning, as I see it.

Re: Datastore/Journal + [IAEP] Coloring books on the XO?
On Sat, Jul 12, 2008 at 2:32 PM, Seth Woodworth [EMAIL PROTECTED] wrote: How do you feel about providing coloring books like activities in sugar? I've found material from the American Red Cross on Disaster Preparedness in around 20 languages[1]. I feel that it would be fairly trivial work to create a template for children to color in in another activity (hopefully the wonderful painting activity from ICDL). Is this work worth doing? Simple to do, and it seems the appeal is that it would make getting used to the touchpad/whatever-input-method-works-in-this-imaginary-scenario a palatable process for veryveryyoungkids while displaying useful information. I say get it done and make it available--but consider simply adding image overlay capability to Colors[1]. It can already overlay a snapshot from the video camera, so holding up any picture/piece of nature/drawing to the camera can accomplish a similar (and more open ended) feat. This is One More Thing that would be a lot simpler and extensible with a more flexible journal/datastore (meaning storing Pictures, Audio, Video, Data [csv files], etc in a way that can be shared between activities). It seems to my uninformed self that, presently, the activities are constraining the output. (Disclaimer: I haven't gotten that deep into journal/datastore programming yet). I copy Eben... a couple sentences on where thought on this is headed? (there's also a video I took of discussion this... I'll forward when I find it) Is a coloring book an effective method of distributing information in a digital realm? One interpretation is that it is a passive way of learning to fill in shapes that have been handed to the child (and those shapes may be artfully arranged to display informative pictures like in comic books). Is it a constructionist method or how could it be made one? Disclaimer: I have read little on constructionism. In fact, I'm not positive that I used the word constructionism properly in that last sentence. Consider the utility of coloring books. It is to provide a colorless guide to draw with a colored medium in and around. (1) The child has a choice of color for each segment. (unless there are letters like R, G, etc in the segments) (2) The child may choose (/struggle) to which extent they color inside the lines Yes, in (1), there is some freedom (the number of segments ^ the number of colors), but it is constrained. How can we take the benefits of coloring books and make them a tool... a hammer. Make it versatile -- so the child can choose what to over/underlay on their painting. They can choose a graph they made earlier that day. Or a grid for drafting a design of their house. Or some Red Cross pamphlets on the school server. Or a picture of a cat they found on Google Images (find edges, anyone?). That's utility. That's something I'd like to have to play with right now. :) Cheers, night, Brian Seth [1] http://www.redcross.org/services/disaster/0,1082,0_504_,00.html ___ Its.an.education.project mailing list [EMAIL PROTECTED] http://lists.lo-res.org/mailman/listinfo/its.an.education.project ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

Please list the maintainer (lead developer) as the first entry. Only list
developers who need to be given accounts so that they can commit to your

If any developers don't have their SSH2 keys on the web, please attach them

7. Preferred development model
[X] Central tree. Every developer can push his changes directly to the
project's git tree. This is the standard model that will be familiar to
CVS and Subversion users, and that tends to work well for most projects.
[ ] Maintainer-owned tree. Every developer creates his own git tree, or
multiple git trees. He periodically asks the maintainer to look at one
or more of these trees, and merge changes into the maintainer-owned,
main tree. This is the model used by the Linux kernel, and is
well-suited to projects wishing to maintain a tighter control on code
entering the main tree.
If you choose the maintainer-owned tree model, but wish to set up some
shared trees where all of your project's committers can commit directly,
as might be the case with a discussion tree, or a tree for an individual
feature, you may send us such a request by e-mail, and we will set up the
tree for you.
8. Set up a project mailing list:
[ ] Yes, named after our project name
[ ] Yes, named __
[X] No
When your project is just getting off the ground, we suggest you eschew
a separate mailing list and instead keep discussion about your project
on the main OLPC development list. This will give you more input and
potentially attract more developers to your project; when the volume of
messages related to your project reaches some critical mass, we can
trivially create a separate mailing list for you.
If you need multiple lists, let us know. We discourage having many
mailing lists for smaller projects, as this tends to
stunt the growth of your project community. You can always add more lists
later.
9. Commit notifications
[ ] Notification of commits to the main tree should be e-mailed to the list
we chose to create above
[X] A separate mailing list, projectname-git, should be created for commit
notifications
[ ] No commit notifications, please
10. Shell accounts
As a general rule, we don't provide shell accounts to developers unless
there's a demonstrated need. If you have one, please explain here, and
list the usernames of the committers above needing shell access.
11. Translation
[X] Set up the laptop.org Pootle server to allow translation
commits to be made
[ ] Translation arrangements have already been made at ___
12. Notes/comments:
If you reject this, I'll stop using headphones in the office. Bad news.
