The Mobile Office in your Jacket Pocket

Sigma is a digital assistant with a Braille keyboard, voice output and approximately as
many functions as you would expect from a Palm or Psion for the sighted, so that
your text documents, appointments, schedules and addresses will always be at hand.
Maximum productivity is safeguarded by up to 96 MB of memory and automatic
synchronization with a PC or Notebook.

Sigma is entirely voice-controlled: several levels of 'talk' and variable read-aloud
options will satisfy beginners and advanced users alike.

Sigma is 'helpful': Detailled online help offers support by way of
easily understandable messages in natural language. A comprehensive manual and a
tutorial in conventional print and in Braille will help you learn. The sophisticated
control is operated optionally via the function keys or a menu (like in Windows programs).

Sigma's high-level performance includes:
-text processing with many functions
-easy document management
-appointment calendar with alarm
-address database
- ToDo-list
- world clock with summer time recognition
- alarm clock function
- up to 10 timers (can all run simultaneously even for several years)
- 'automatic' diary
- calculator
- currency, weight, distance units converter
- dictionary with lots of useful information
- integrated longhand and shorthand translator (SBSBRL)
- spellchecker
- parallel processing of many texts simultaneously (paragraph, search, replace,
copy, print)
- text format converting
- macro-enabled
- batch processing for complex procedures
- automatic data synchronization with PC

Sigma is programmable in Basic and C with special libraries for synthetic voice
output: Why not write your own programs and integrate them into existing functions?

Sigma is compatible: (limited) DOS compatibility guarantees maximum data
compatibility with a PC or Notebook in Windows. Can be connected to Braillezeile
and Braille printer. Many DOS programs can run in text mode.

Sigma is ergonomic: key spring-back action and required pressure are comparable to
the requirements of a high-quality keyboard. 6 or 8 point Braille possible. The voice
output is very easy to understand with a clear, pleasant pitch in different voices
and variable talking speeds.

You can speak onto Sigma under Windows or DOS, where it works like a PC
drive, so that manual file management (file transfer, delete, rename) becomes
exceedingly simple. In addition, each input can be directly monitored on the PC
screen.
