Electronic organizer
An electronic organizer (or organizer) refers to handy computers that use a personal information manager functionality (PIM) to save and organize data, addresses and appointments in an electronic database. Electronic organizers have a keyboard (from approx. 1987 a QWERTY keyboard), which enables data to be entered quickly, but they have no cellular or Internet functionality. An energy-saving design enables “electronic organizers” to operate for weeks with just one set of dry batteries ; A lithium buffer battery also ensures data retention for several years when the operating batteries are empty.
history
In the early 1980s, powerful programmable pocket calculators appeared on the market , some of which were equipped with QWERTY keyboards ( Sharp , HP , Psion , Casio , etc.). As microcomputers, these could also be used for electronic appointment , address and task management, and therefore often replaced a paper organizer. These devices were therefore no longer marketed as programmable pocket calculators, but as electronic organizers in the German-speaking world. ( Psion Organizer as Psion).
In the course of the market launch of Personal Digital Assistants (PDAs) in 1993, which were not operated with a keyboard, but only via a touch-sensitive screen, and finally also due to the market success of the devices from the manufacturer Palm with handwriting recognition that was suitable for everyday use for the first time, Electronic Organizer disappeared in largely off the market in a short time
Organizer for the blind and visually impaired
Since the conventional organizers can usually not be used by the blind , aid providers have developed special devices for blind users.
The product range extends from the small note-taking device that only has voice output to the model with a notebook keyboard and integrated Braille display .
