Demonstration build: Difference between revisions

Latest revision as of 15:58, 30 September 2008

The XO is often presented in demonstration, at events, to new users, or as a showcase for what would be possible under different school or low-infrastructure scenarios.

Demonstration build

There are many capabilities of the XO that aren't easy to demonstrate on a standard build. We are preparing a set of builds that can show off the features described here.

Dual-boot
- with a Fedora/Gnome or Edubuntu setup (via SD card)
- with any simple hacks to speed up launch -- perhaps a dual-boot OpenWRT?
Video (full screen)
- ogg
- m.youtube / kaltura
- the best that can be done with mpeg & rm
  - has been done using a completely separate build which was stripped of absolutely everything but the ability to play video (No "OS"/GUI at all), and uses proprietary codecs
Audio
- Stereo sound to show off speakers range
- multichannel audio from creative activity (tamtam)
- Duet example
- streaming audio from an online source
Book Readers
- pdf (evince)
- js (flipbook, ICDL, jresig)
Flash
- smooth Flash animation with gnash
- the best that can be done with Adobe Flash
text-to-speech
- Speak
videochat or at least audiochat
drawing w/ stylus
- phun / elements / crayon physics
Browsers
- Full-fledged firefox
- Opera
New Sugar UI and configuration screen
Faster load time (now in joyride)
Abiword
Develop/ Pippy
Xaos Python fractal viewer
Modified xoIRC -- auto join #olpc
a plot of battery strength/usage over time, however crude, like what the Prius offers for gas conservation
a compressed view for the Journal (or a way to link directly to a compressed view)

There are also a number of activities whose demos should be focused down to a couple of minutes, whose components could all be set up in advance; I'm thinking about how to effectively walk through them, without waiting to long for each one to load and set up, but without having more than one in memory at a given time. Is there some way to launch an activity while simultaneously demanding/reserving a block of memory, potentially killing other processes when starting up to improve the repeatability of demo length?

Progress

Here is what is done (from the list above)

full-screen full-motion video
- Ogg / mpeg / many other proprietary codecs all fully supported via mplayer
  - In full screen mode game keys are used for control
  - Usage: mplayer filename
  - Media: Elephants Dream
Book Readers
- Read / Evince working
- ICDL working
Audio
- Stereo mp3 playback working via mplayer
- Streaming audio working via mplayer
Flash
- gnash installed + working
- Adobe Flash player installed + working (latest Flash runs youtube videos at 5-10fps)
Text-to-Speech
- Speak installed + working
Tablet Example
- Unexciting proof of concept tablet activity installed + working
- Tablet drivers may work on joyride but there aren't any interesting activities that show it off
Browsers
- Full-fledged firefox installed + working
- See firefox2 for guide
  - Works well for the most part, it is not the ideal browser for the XO.
  - Designed for a windowed GUI, full of features that are not helpful in the XO enviornment
- Opera
  - Works very well, definitely the happy medium between Browse and Firefox
  - See Opera for installation guide
New Sugar UI and Config screen
- integrated into the joyride-1914 build used
Faster startup
- integrated into the joyride-1914 build used

Difficulties / Requests

Playing youtube video
- Gnash not compatible via youtubes website
- Adobe Flash runs youtube at only 5-10fps
- Mplayer can't seem to play the rtsp stream from m.youtube.com
Need a good TamTam demo

Types of demos

Situational demos

XOs used in

an emergency school (school-in-a-box)
a tiny village w/unconnectivity (digital courier)
a disaster / zero-infrastructure intervention
an agriculture/water intervention
a health intervention / clinics

Learning demos

Children learning...

geometry (Dr. Geo)
collaborative music (lifelong K w/ distributed orchestra)
language
art (interactive creation)
writing (abicollab)
world maps

Parents learning

spreadsheets
geography
