Somebody is finally thinking of the children

Laptop

7.5 inch diagonal screen at 1200x900 (200 dpi)

800x600 in grayscale

Sunlight readable!

Wi-fi, USB(x3), mic, speakers, camera, SD

Screen rotates to tablet mode

Water resistant keyboard

walk in the rain with it!

More laptop

Laptop, turned on its head

All electronics are in the upper section, except the keyboard.

Easy to replace either component

Carry handle also acts as base stabilizer

Wi-fi rabbit ears double up as latches

Any 12 volt power supply will do

wall wart

car battery

crank power

Green

Looks green, works green

Fully recyclable

5 year life span

Idle power consumption

Desktop 80 watts

Laptop 20 watts

OLPC 1 watt

More green

Power consumption at about 10% of typical laptop

The laptop lifetime is 5 years or 2.5 times longer than a typical laptop

Half the size and weight of a typical laptop

Goal: not a single XO laptop should end up in a landfill

Power innovations

Batteries that last 4x longer

Lithium Iron Phosphate (LiFePO4)

Currently at ~ 5hrs, final goal ~10 hours

Display refresh possible with board powered off

0.1 watt in grayscale mode

Wireless mesh works even when board powers off

Mesh does not require central hub-like infrastructure

Look Ma! No moving parts!

No fans, no hard drive, nothing spins.

1GB Flash + 256 MB RAM

USB storage

SD slot

Only thing that moves is the screen when it swivels over to tablet mode.

AMD Geode processor runs cool.

Linux in the box

Custom Fedora based distro

GNOME-based

Ported applications must follow OLPC HCI guidelines

Sugar, because its sweet!

Sugar

Activities, not applications

Interface Sugar

GNOME based

Borders + center wheel

Wheel is also a metaphor for available resources

Run your own Sugar environment

Applications

Word processor

Yes, but does it run Word?

Paint

Instant Messaging

XMPP based

Browser

Firefox/gecko

Record

stills and video

Bitfrost Approach

Open design

The laptop's security must not depend upon a secret design.

No lockdown

There must exist a way for the security systems to be disabled for maintenance.

No reading required

Security cannot depend upon the user's ability to read a message from the computer.

Unobtrusive security

Whenever possible, the security on the machines must be behind the scenes.

Bitfrost Goals

No user passwords

Users as young as 5 years old, cannot remember a password.

No unencrypted authentication

Authentication of laptops or users will not depend upon unencrypted data over the network.

Out-of-the-box security

The laptop should be both usable and secure out-of-the-box.

Limited institutional PKI

Keys will not be used to validate the identity of laptop users.

Education

Its an education project, not a laptop project.

Nicholas Negroponte, Founder - OLPC

OLPC's Goal:

To provide children around the world with new opportunities to explore, experiment and express themselves.

Yes, but the laptop is way cool!

Building Content

Constructionism is a philosophy of education in which children learn by doing and making.

Electronic books created and stored on the school server

Collaborative activities

IM, Video, Music

E-toys

Build books with multimedia content

Think Lego

Learning outside the box

With sufficient self-confidence, teachers can learn from children without risk of unraveling the fabric of educationquite the contrary, improving it.

Children must not only own the laptop, but take it home. In so doing the whole family will benefit.

The child is not the object of change but the agent of change.

Free and Open Source

FOSS was the only option that was flexible enough for this project

No vendor lock-in on formats

No royalties on redistribution

Perhaps the first example of a software project that has forced hardware manufacturers to modify their way of business.

FOSS: What does it mean?

OLPC manifesto

Four freedoms

Open Source Definitions
