Tracker is a hands-free mouse that translates your movements into direct movements of the computer's mouse cursor. It imitates a standard desktop mouse or trackball allowing hands-free control of the computer.

Tracker holds a sensor that tracks a tiny, reusable dot that is placed on either the users forehead, glasses or any part of their body that they have good controlled movement of. Example: Head placement, When your head moves, the cursor moves.

Tracker gives you wireless access to your IBM compatible or Macintosh computer using either a PS/2 or serial mouse port. Precise tasks such as drawing or computer drafting are accomplished easily. Pointing actions for games, surfing the net and general computer maintenance are also easily accomplished through Tracker.

Tracker also gives you three options to handle the clicking functions necessary to complete any of these tasks: single switch access; WISP, Madenta's wireless sip/puff switch; or a dwell selection program such as Magic Cursor for Macintosh or Gus Dwell for Windows.

New to Tracker this year:

WISP 2000- Wireless Integrated Sip/Puff Switch

You have Tracker. Now how do you do the mouse clicks? The answer: WISP. A discreet sir tube mounts on your ear and connects to a battery-operated transmitter belt-pack, about the size of a pager. Puff or sip on the tube to perform mouse functions-puff for left mouse button, sip for right-and the transmitter sends the message wirelessly to a receiver plugged into Tracker. Wireless freedom allows you to move around the office or leave your work area without having to disconnect your equipment.

New to WISP this year:

Screendoors 2000

Screendoors 2000 provides you with an on-screen keyboard and word prediction. Used incombination with a hands-free mouse, you can have complete hands-free access to the computer. You can enter text at an improved rate into any program running on you computer.

As you type, the Word Predictor in Screendoors 2000 searches for the most likely word9s0 it believes you're attempting to enter. It then offers works in the Prediction list for you to choose. Screendoors 2000 word predictor is a learning predictor. If it's not familiar with a word you're typing, it learns the word and includes it in the Prediction list for next time. As well, the Predictor will predict next possible words for the one you just typed.

New to Screendoors 2000 this year:


PROXi is a fully integrated home and office automation solution that gives you independent control of the phone, 256 electrical devices, eight remote controls, an intercom system, and a bed controller.

You can control PROXi with a IBM compatible or Macintosh computer using access methods such as: voice commands, keyboard entry, point and click, or single-switch scanning. PROXi can also be controlled by a wide variety of Alternative Augmentative Communications (AAC) devices including IntelliKeys, Liberator, Ke:nx. GUS, and Dynavox.

PROXi has been designed to help you be more independent and have more convenience at home or in the office. However, PROXi is not a replacement for a full-time attendant.

What's new in Environmental Control Units this year at Madenta Inc.


Nemo is a device, which can mount on a wheelchair and recognizes the spoken commands of a person with a disability to control their surroundings. A person with a physical disability may find it difficult to turn on lights, answer the telephone, or control their television. Using Nemo, all they have to do is say "lamp on"; Nemo immediately recognizes their voice and sends out an infrared signal (like a television’s remote control) to turn on the lamp. Through this process, Nemo can control dozens of devices, including lights, the phone, televisions, door openers, and intercoms.

If the person with a disability can’t speak, there is a single switch-scanning mode as well. All they have to do is watch a menu on the backlit LCD screen and press a switch when the desired item is hilited.

Complete standalone system, does not require a computer to setup or make changes to in the future, simple and clean.
