Papenmeier Braillein Keyboard

Introduction

The BEAM XVI-SB is an X-Windows terminal for use by the Visually Impaired and Blind. It comprises a base unit,Alva braille display,monitor and keyboard. Normally a standard 105 Key PC style keyboard is supplied, this document is intended as a refference when an alternative braille format keyboard, the Papenmeier Braillein is added.

The Braillein is a keyboard that has but 19 keys. These keys are pressed as 'chords' to obtain the appropriate 'PC keyboard' equivalent. This is best illustrated by example - To obtain the letter 'b' the braillein user must press and then release together the keys 1 and 2. To make things simpler for the braillist the keys 1 to 6 represent the normal braille letter pins.

The Braillein keyboard has 8 keys that represent the eight dots of a single braille character cell. In addition there are 4 function keys, 4 cursor keys, a space bar and 2 modifier keys (the left shift and right shift).

Installation

The Braillein keyboard can be connected in two ways. Together with a standard keyboard or stand alone. In the 'Tandem' mode a user may use both keyboards.

Stand alone The braillein has two 'flying' cables attatched, connect the 5 way din style plug into the socket on the base unit.

Tandem Connect the 5 way din style plug into the socket on the base unit and connect the normal keyboard into the socket on the Braillein flying lead.

Usage

The reader should be familiar with the operation of the BEAM XVI-SB terminal as controlled by a normal keyboard. If not, then please refer to the XVI-SB documentation.

The Braillein keyboard has three states. Normal, XVI-Object and XVI-Text. The two XVI states are used to control the special features of the terminal. The D key on the Braillein moves between the states while the RS key will return to normal mode regardless of the current state.

In normal mode the eight central keys represent the dots of a braille character. The standard used is US computer braille. Key 7 is used as a shift key. For example key 1 is a, keys 1 & 7 is A.

The following diagram and table show the Braillein key presses and their actions in Normal,XVI Object and XVI Text modes.

Special Keys

To obtain the normal PC Control-<Character>, press the appropriate character key together with keys 7 and 8. For example CRTL-A = 1 7 8.

To obtain the normal PC ALTl-<Character>, press the appropriate character key together with the RS key. For example ALT-A = 1 RS.
