WikiReader

from Wikipedia, the free encyclopedia
A WikiReader with an activated on- screen keyboard .

WikiReader was a project that made it possible to display a text version of Wikipedia on a mobile device. The project received support from Openmoko . The source code has been published.

In October 2009 the project presented a portable offline reader for Wikipedia. Updates in different languages ​​were available online; so there were Wikireader versions of the English Wikipedia, Wiktionary, Wikiquote and the Gutenberg project, which could be installed together on a user provided SDHC memory card (16 GB). In contrast to Wikipedia itself, the device has a child safety feature .

The device can also run Forth programs; a simple calculator application is included.

At the end of 2014, the WikiReader website was closed and the project was discontinued for unknown reasons. Since then there have been no more database updates for the existing WikiReader. Devices and self-made updates are only available on the secondary market .

restrictions

  • Text-only display: The WikiReader device can only display text. Therefore, no Wikipedia images are saved or displayed.
  • Tables: The WikiReader does not display any article text that is located within a Wikipedia table.
  • HTML "special characters": WikiReader can not process certain HTML special characters ( entities ) in the Wikipedia article text, so these are not shown on the display.
  • Mathematical formulas: The original version of WikiReader could not yet display any information encoded with LaTeX (see mathematical expressions ) as a formula in Wikipedia articles. This fact was corrected with an optional firmware update, which is preinstalled on newer WikiReaders.
  • Dealing with omitted information: WikiReader does not provide any indication of gaps in omitted passages in an article. This concerns z. B. Pictures, tables and mathematical formulas as well as other information that could not be converted into text format and are simply left out without allowing any conclusions to be drawn about the resulting information gap.
  • Search function: The search options of the WikiReader are very rudimentary. There is no full-text search option . You can only search for lemmas from Wikipedia articles. WikiReader supports the suggestion search for article lemmas, starting with the first letter of a lemma. Search terms must be entered correctly. Searching with wildcards is not supported.
