Lightwriter SL35

What is a Lightwriter?

A Lightwriter is an easy-to-use portable communication device. The user simply turns it on and types a message on the keyboard, which appears in the dual displays, and can be spoken out loud with DECtalk speech synthesis.

Lightwriters are designed to help individuals with speech impairments, autism, laryngectomies, cerebral palsy, head injury, and persons with progressive conditions (i.e. ALS/MND) communicate. The Lightwriter is small, lightweight, and attractive in any situation.

Standard features of the Lightwriter SL35:

  1. Dual Displays – One facing the ‘user’ and the other facing out to the ‘communication partner’. This feature alone enables face-to-face conversation as the displays are bright and the text large and easy to read, even at a distance. Listeners aren’t required to hunch over the user’s shoulders to see what’s being said.

  2. Compactness and Attractive Design – Readily portable and easy to handle
  3. Ease of Use – Most people can turn it on and begin using it with minimal instruction or manual reading
  4. QWERTY LightTouch raised-key keyboard – The specially-designed highly legible, splash proof, LightTouch keyboard requires very low operating force to operate.

    The adjustable keyboard surround can be raised to give a low-rise support for people who may have slightly inaccurate key selection. An optional Deep Keyguard is available.

  5. DECtalk speech synthesis for English – American-English male, female – and child voices included. Speech exceptions ability is built-in for making special words sound right. Any word typed will be spoken aloud to give a natural form of communication, and allows conversation over the telephone.

    Listen to samples of DECtalk Text-to-Speech voices (WAV):

    Acapela HQ natural voice speech synthesis is available on models SL38, and SL85. Other European languages and speech synthesisers are available as options.

  6. Memory – Store memories so that frequently used words or phrases can be retrieved quickly
    • 36 memories of up to 250 characters each: one memory for each of the letter and number keys
    • Abbreviation Expansion – Frequently-used words or phrases can be stored and retrieved as a 2 or 3 key code, e.g. DC = “I’d like a drink of coffee, please.”
    • Speedwriting – Add your own speedwriting abbreviations (SPDWRTG ABBREVS)
    • Facility to browse through the memories to see what is stored
    • Sequences: use 2 keys to play complicated key sequences, such as: “Print eight memories, with gaps between, the first one bold and the last one italic”

  7. Text Prompting/Word Prediction – Set up word prompting after selection of 1, 2, or 3 characters (or none). Stored vocabulary can be scrolled for visual selection.
    Examples of prompting after typing one character:
    • If T is selected, the display will show The, if H is then selected, the display will change to THat, etc.
    • Or, if T is selected, the display will show The. Then scroll to choose from the stored vocabulary list.

  8. Context Sensitive HELP – Online context sensitive help (an abbreviated handbook onscreen) is available with setups, etc.

Other features include:

  • Built in buzzers – to summon attention
  • Expansion ports – connect to printers, plug in alternative PC keyboards, and connect to computers to back-up or edit memories and to save settings
  • Tremor control – adjustable tremor control to suppress inadvertent key presses
  • Adjustable speed of replay of messages and memories
  • 8-function calculator built in
  • Speech Exceptions
  • Two call signals with buzzer button
  • Adjustable Auto-off

Lightwriter SL35 Options

Custom factory-built models with the following options are available to suit everyone’s different needs. Some of the options are:Alternative VFD Display

  • Alternative VFD Display – If the standard LCDs do not suit, one or both displays can be substituted with vacuum fluorescent displays (VFD) to help users with low vision. The text and display width on the VFD is smaller but the characters are brighter than those on the LCD.
  • ABCDE Keyboard Layout – If the user is not familiar with the QWERTY layout, the keys can be arranged in ABCDE layout. The unit can be supplied in this layout (at an extra cost) or the keys and software can be changed in the field.
  • Switch Scan Module – The Lightwriter can adapt to scanning with one or two switches for users with progressive conditions who become unable to continue using a keyboard.
