アプリケーション

基本システムを拡張する取り組みが3種類あります。それは調査用ツール、表現用ツール、そして協力用ツールです。 組み合わせについては、hereを参照してください。

There are three types of activities distributed with the base system: tools for exploring, expressing, and collaborating. A matrix of applications that have been (or are being) built for the laptop can be found here.

ツール(調査用)(Tools for exploring)

  • a web browser built on the Firefox engine;
  • a simple document viewer based upon evince (including the ability to view PDF);
  • News Reader, an RSS (“really simple syndication”) reader (PenguinTV);
  • multimedia playback using gstreamer (the Real Networks Helix™ platform has been ported to the laptop and is available for download but is not part of the base distribution);
  • OpenDocument Viewer to read documents in OpenDocument format, a highly-compressed format that is a fully open international standard (ISO 26300);
  • The Opera web browser and the Real Networks Helix™ platform have been ported to the laptop and are available for download but not part of the standard distribution.
  • Measure, a tool for exploring the physical world by measuring DC and AC voltages, observing them on a oscilloscope like interface, being able to watch waveforms in frequency domain (spectrum analyzer), logging data at a specified time interval, and drawing the graph of logged data.
