Re: [Sugar-devel] Children want Sugar 0.84, for the wrong reason
See http://bugs.sugarlabs.org/ticket/535#comment:5, Expose Journal, Home, Group, Neighborhood, Frame Sources, where it's suggested that we extend the 'Show Source' facility to more of Sugar. Learners like to exercise and demonstrate their knowledge by customizing or changing their environments. We can guide them to learn deeper concepts by giving them ways to encode their customizations. (Providing a convenient undo, save, and restore facility for their work would accelerate their learning.) The 'Modifying Sugar' chapter in our manual, http://en.flossmanuals.net/Sugar/ModifyingSugar, provides a nice entry ramp for this learning activity. We could provide a similar tutorial for other Sugar features and then benefit from the creativity of all our learners.

I feel that Sugar should aim to reach the same level of hackability of eToys: every UI element is an object that you could drag, drop, copy or modify. Of course, this has consequences in terms of stability and clarity. Before we could unleash this power we need to think of ways to recover from mistakes. If multiple undo is too hard, a restore everything to defaults might be good enough. Perhaps we're worrying too much. Re-installing the system from USB takes only 3 minutes and is already being done very often. A boy just showed up on the door of the repair lab, saying: se borró el Navegador (the Browse activity deleted itself :-) All we need to do is make the backup-update-restore procedure slightly more automated so that kids and teachers could do it without bothering the technicians. Actually, we don't even need to worry too much for a solid backup and restore procedure. I've always suspected that most kids wouldn't care about preserving their diary. Now it's confirmed: kids are flocking here to get the new version of Sugar even though their journals are not going to be preserved across the upgrade. On the other hand, teachers and teacher trainers always ask to preserve the content of their journal. Technicians use a pair of simple shell scripts to tar up the journal to a USB stick, so they don't depend on being within the range of the correct school server.

Re: rotate button sucks on the XO
By opening the XO in its traditional laptop configuration and then holding it by the handle as if it were an opened book (twist 90 degrees), results in a portrait mode configuration that is more ergonomic for a standing user and perhaps more comfortable for casual use while sitting on a couch or in a reading chair. Applications for such a use might easily be imagined. The track pad and keys would be available and could be exploited by application designers.

Most people at OLPC will tell you we are not a 'company'. ... I have been trying to understand it, explain it, live with it , and improve it for a year now. What I think is going on is a unique and somewhat chaotic (perfect storm?) intersection of non-profit, open source, research lab cultures with the need to ship a real product. This is excellent analysis. And I'd go a bit further than Kim actually in saying that I don't feel particularly bad that we are a bit of a mess. Being a bit of a mess means that we are breaking new ground so quickly that the ground is changing faster than the org gets used to it. Which leads to a few observations (which overlap somewhat with what Kim is saying) - IME, people complaining that we don't know what we are doing can be a positive indicator. The scenario outside the car is changing! - Learning to organise and handle new situation X is only worthwhile once we are confident that X is here to stay. - Therefore, there will be many situations that are impossible or not worth to be well prepared for. So being a constant mess is a reasonable approach. We can handle that by saying that strange new situations are common, and we have to keep an open mind and be ready to work w the team to get new and strange things done. - Prioritisation is important. Some things are too much of a distraction. Letting them go to hell can be less disruptive than an all-hands effort. This is - IME - the hardest part. When everyone is ready to take on whatever comes, it's hard to avoid getting the team distracted. Which can also be stated in more blunt terms: We are doing development of new stuff! If you want it predictable and organised, I hear EDS is hiring - the processes and procedures manual is 800 pages :-/ All of the above is from my experience in various organisations large and small, and govt and private. We are radically diffrerent from a big corp, and even from established non-profits. In this space you can expect us to be very good at a couple of very specific things, and a complete mess about a lot of other stuff. We will have to get good at some of that other stuff... in the meantime it'll be frustrating. :-/ There's a good book about this - Waltzing with Bears by either DeMarco or Yourdon, that says basically: if you are considering a project that doesn't take you into uncharted territory, *can it*. It's not worth it if it's not so new that you feel lost and helpless. It's written for big corps that are frozen in terror ;-) but it applies to what we are doing @ OLPC. Uncharted territory.

Re: typing tutor activity
Hi Kate, Please consider the ergonomic and safety aspects of this learning activity. I remember well how my piano teacher provided protective oversight by watching my activities even during a short, 30-minute, weekly lesson. She had me pause and rest for a couple of minutes, after about 15 minutes of continuous or even shorter periods of intense keyboarding. If you could incorporate code to accommodate an algorithm that monitors typing intensity, such as, keystroke rate and continuity, this could be used to issue appropriate reminders to the user to rest their hands, eyes, and other body parts from intense activity. A simple algorithm might be one that monitors the exponentially weighted moving average of time between keystrokes based on accumulation of the output of a timer counter that is read at each keystroke. Some calibration of the work model parameters with actual use data will be needed to set reasonable triggers for the rest reminders. Having such an on-board safety coach would be of great advantage in building an awareness of the body's physiology and it's limits, and contribute another important lesson for the child's safe growth and maturation. I've posted a formula for the exponentially weighted moving average on the OLPC wiki at http://wiki.laptop.org/go/User_talk:FGrose#Keystroke_monitoring . There is also some discussion of XO ergonomics at http://wiki.laptop.org/go/User_talk:FGrose#Ergonomics.2Fsafety. Please write if you would like more assistance. Best wishes, Frederick Grose, MPH, CIH ... The goal of this project is to deliver an activity that allows teachers to create typing lessons for children that are written in the kid's native language using age-appropriate words and sentences. The application will do this using a flexible lesson screen that displays an on-screen keyboard and one or two of a variety of tools to indicate progress/speed/accuracy etc. For each lesson, the lesson screen will be formatted using the lesson text and settings provided in a separate text file edited/written by teachers. As time permits, I plan to develop a GUI interface to help teachers create these lesson text files. If you have any comments, suggestions, or feedback on this project please let me know. ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

OLPC Usability Testing Class Project
This note is a request for the broader community to consider potential topic areas that might be prime for some usability testing. (Here is a quick review of usability testing, http://en.wikipedia.org/wiki/Usability_testing.) Professor Keith Karn in the Information Technology Department, http://it.rit.edu/it/, of the Rochester Institute of Technology (RIT) in Rochester, NY will have 4-5 graduate students (from his class of 20) propose, and over the next 10 weeks, execute a usability testing consultation around the XO or OLPC project. The class met for the first time on Wednesday 12 March 2008, and will meet, as a whole, every Wednesday 6-9:50 pm EDT through 21 May 2008. This OLPC project team will be asked to review the wiki.laptop.org and then contact me as client representative. Because of the academic schedule, we need to review and select a testing topic area in the next 7 days and have a final testing plan prepared by 26 March 2008. What usability issue is currently most timely and significant to the project? Since OLPC is developing a new information and communication technologies platform, there are many possibilities for significant target users, subsystems, components, and activities. Please think about the project design needs, possibilities, and constraints, and suggest topics or issues here or to our wiki page, http://wiki.laptop.org/go/OLPC_Rochester%2C_NY#Project_ideas. We have a few G1G1 XOs in Rochester that we should be able to use for live testing with local children. Larger scale tests could be performed with emulated XOs or hosted Sugar in the RIT Usability Laboratories. The class will be expected to go through the human subject reviews as required. Because so many cultural variables may be important modifiers of understanding user interactions with the OLPC project, perhaps there may be some more basic or common psycho-physical aspects of usability we could address that would be timely and significant for the project. Or, we might be able to recruit user participants from one of the recently settled immigrant communities in the Rochester area to delve into the internationalization and cultural domains. Some reviewers of OLPC have been critical of the shortage of reported usability testing results, so far, however, if we appreciate the pace and resourcing of the development, perhaps this is a chance to address any gaps or curiosities that you may have. We would welcome your thoughts (particularly on usability issues in the near term). Thanks to everyone for all their efforts! ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
