There's been a lot of buzz coming out lately around the One Laptop Per Child (OLPC) program and it's founder, technology guru Nicholas Negropnte, but most of this centers around creating a $200 laptop. If you are not familiar with the program, Negropante wants to bring inexpensive network computing, the XO laptop, to children in the developing world, and recently announced a program where anyone can buy one of the inexpensive green laptops if they also buy one that's given to one of the two billion children in the developing world.
There are a lot of interesting and ground-breaking features that OLPC's XO Laptop is including, but one that I don't think receives much attention is it's new interface for computer-human interaction. According to the OLPC site:
The desktop metaphor is so entrenched in personal computer users' collective consciousness that it is easy to forget what a bold and radical innovation the Graphical User Interface (GUI) was and how it helped free the computer from the 'professionals' who were appalled at the idea of computing for everyone.
Negroponte and his crew want to evolve the WIMP (windows, icons, menus, pointer) GUI model away from the business oriented desktop metaphor. Instead, Based on observations by MIT professor Seymor Papert about how kids work with computers, they have created a 'zoom' interface called SUGAR that brings your work off the virtual desktop and into a virtual world, emphasizing community connections. Its principles include:
So how do you build an interface around these principles? Not having seen it in action, it's hard to tell from the screen shots provided in the interface demo on the OLPC Web site. They show a series of screen captures without captions and no clear path being followed. However, it looks as if it keeps things simple with you (the user) at the center surrounded by icons representing your immediate network community and activities you can perform. As you work, the interface zooms around as needed, allowing you to join in activities with other members of your community. For example, it's Web browser not only allows you to annotate pages, but also chat with others in your community directly on the page.
The XO interface is definitely is not your father's PC interface, but whether it catches on will depend a lot on how rapid its adaption rate is around the world. If 2 billion children grow up using the OLPC XO Laptop and thinking of it as the way computers work, then Apple and Microsoft may have no choice but to follow the new leader.
