Sugar: a different interface
http://laptopgiving.org/en/software-and-interface.php
Sugar
● Focus on activities, not applications– “Write” a letter vs. “use” Microsoft Word– Educational vs. Vocational
● Run your own Sugar environment!– Download ISO image at
http://wiki.laptop.org/go/LiveCD– Burn to CD.– Boot computer with CD. No installation
required!
Activities
● Write– A simple word processor
● Chat– XMPP based. Same as Google Talk
● Browse– Firefox-based + flash + AJAX
● Record– stills and video
More activities... http://wiki.laptop.org/go/Activities
One forward, One right
An interesting way to draw a circle in TurtleArt
One step forward, wait for one second,
one degree to the right, repeat 360 times
The wait allows you to see the turtle draw
the circle slowly

the XO laptop
Laptop
● 7.5 inch diagonal screen at 1200x900 (200 dpi)– Sunlight readable!
● Wi-Fi, USB, microphone, speakers, camera, SD card slot
● Screen rotates to tablet mode● Water resistant keyboard● Dust resistant design
More laptop
● Laptop, turned on its head– All electronics are in the upper section,
except the keyboard.– Easy to replace components– Carry handle also acts as base stabilizer– Wi-Fi rabbit ears double up as latches and
increase range– Any 11 to 24 volt power supply will do
● wall charger, car battery, crank/yoyo power, solar panel
Hand Crank Charger
http://wiki.laptop.org/go/Peripherals/Hand_Crank
Solar Panel
http://wiki.laptop.org/go/Product_News#Solar_Panels
5 Watt/14Volt panel
Green
● Looks green, works green– Fully recyclable
● 5 year life span
– Idle power consumption
● Desktop – 80 watts● Laptop – 25 to 60 watts● OLPC – 1 to 8 watts
Power
● Batteries that last 4x longer
– Lithium Iron Phosphate (LiFePO4)
– Currently at ~ 5hrs, final goal ~10 hrs
● 0.1 watt in sunlight readable mode● Running at full blast
– Wi-Fi, full backlight, camera, microphone, speakers
– 7 to 8 watts
Mesh Networking
● Mesh does not require central hub-like infrastructure
● Wireless mesh works even when the CPU suspends
Based on an early draft of IEEE 802.11s
No moving parts
● No fans, no hard drive, nothing spins.– 1GB Flash + 256 MB RAM– USB storage– SD slot
● AMD Geode processor runs cool. – Does not need a fan to cool it off– No air slots or ducts
Linux in the box
Fedora 7 and 9 based builds
Sugar runs on popular Linux distros
FOSS: Free and Open Source
● When the project started FOSS was the only option that was flexible enough for this project
● No vendor lock-in on formats● No royalties on redistribution● No discrimination based on fields of
endeavor● Scalable global model for software and
content
FOSS makes it happen

Sugar Guidelines
http://wiki.laptop.org/go/OLPC_Human_Interface_Guidelines
Activities, Not Applications
● There are no software applications. The laptop focuses children around "activities."
● Activities are distinct from applications in their focus —collaboration and expression– Abiword becomes Write– Firefox/Gecko becomes Browse
Presence
● Everyone has the potential for being both a learner and a teacher.
● Employs a mesh network that interconnects all laptops within range.– Telepathy framework
● Telepathy-gabble for using a Jabber server across the Internet
– http://wiki.laptop.org/go/Telepathy_Gabble ● Telepathy-salut for p2p/mesh collaboration
– http://wiki.laptop.org/go/Telepathy-salut
Tools of Expression
● The laptop is a "thing to think with"● Principle of "learning through doing"● Constructivist learning
– http://wiki.laptop.org/go/Constructivism
Journaling
● The concept of the Journal, a written documentation of everyday events,
● Journal metaphor for the filesystem as our basic approach to file organization. – http://wiki.laptop.org/go/Journal
