Since 1990 we have worked as electronic engineers in the field of computer aids for handicapped persons. We design and assemble complete workstations for physical, visual or mental disableds and for the blinds. Moreover, we produce special aids for computer access such as microkeyboards, braille keyboards, mouse simulators and other input units. Our electronical aids are distributed to customers all over Europe. We develop individual computer based solutions for severe and multiple handicapped persons to make possible verbal communication, writing or environment control.

Micro keyboards M32 with mouse simulator

 prices (article ts-m32h)

The micro keyboards M32h and M32q with mouse-simulator are aids for disabled persons to operate a computer despite of their severe handicap. It might be a very low muscular strength in the upper limbs, causing a very limited work range of the hands and a small finger power to stroke normal keys (Muscular Dystrophy, ALS,...). In this case a computer serves as communication or writing aid or as an environment control device.

Our micro keyboard is a very small sized keyboard (4inch x 4.3inch) with closely spaced switches. The keys require zero force using a magnetic stick. The various hand hold sticks are very slight and balanced (optional mouth stick, headpointer or finger splint).

The M32q has a landscape layout similar to a standard keyboard, while the M32h is layouted in portrait format useful for the capabilities of different operators. Closed to the keyboard area (right or above) a set of switches of the same type gives access to a mouse controlling 8 directions of the mouse cursor and the two mouse keys including double click and drag-and-drop.

The keyboard case can be arranged tabletop or in any placement using mounting systems. Both keyboards are fully compatible with a standard keyboard and mouse, no special software (drivers etc.) are required.

Mini keyboard M42 with different mouse simulators

 prices (article ts-m42ta)

The mini keyboard family M42 consists of small sized keyboards (only 7.7inch x 4.3inch x 1.2inch) with closely spaced microswitch keys (grid of 0.4inch) and mouse simulators like mini trackball, touchpad or key controlled simulator, depending on the handicap. Concerning the use by motor impaired persons the M42 is between the standard space saver keyboard and the special micro keyboards with magnetic sticks (M32, see above).

A very little strength is required to activate keys, they can be stroked by finger, mouth stick, headpointer or splint. Keys like Alt or Ctrl lock automatically. The mouse simulator has additional keys for double clicking and drag and drop.

The small size case insures that a small range of movement is sufficient to access entire keyboard and mouse. The keyboard is easy to mount in any position using an optional mounting system.

The M42 produces all the keycodes of a standard keyboard and interact with the computer like such a keyboard and a standard mouse.

Expanded keyboard with mouse simulator    (Sumo)

prices (article ts-gr-03)

In case of severe motor impairments the use of a standard keyboard with a keyguard is often insufficient. For these computer users an expanded keyboard may be a powerful aid. An expanded keyboard prevents unintentional activation of one or more than one key at a time by well spaced, enlarged and slightly recessed keys and allows the user to stabilize limb on keyboard without activating keys. The resulting large size case requires a wide range of movement on the flat panel keyboard.
To limit these straining movements and to obtain a higher input efficiency a special layout has been designed. It places the most-often-used keys of the German language in a small area near the center of the layout, rarely used keys in a larger distance (we localize it depending of your national language).
Another new feature of our expanded keyboard is the ability to activate a special mouse mode by key or program. In this mode, the cursor keys control the mouse cursor and the other cursor keys (Page Up/Down, Home, End) emulate the mouse clicks, the double click and keylock of the left mouse key.
The expanded keyboard plugs into the USB interface , no special interface or drivers are needed.

Input unit Keyboard/Mouse    (Bedieneinheit)

prices (article ts-be-8/30)

To reduce confusion for the novice computer users, children, or mental impaired persons a special input unit has been designed. It can operate even in keyboard mode or in mouse mode using the same sensors and it is very useful for low level educational software, simple computer games or therapy software.

These input unit is configured with 9 sensors. The internal sensors (external sensors are optionally) are round pads with diameters from 1 inch to 2 inch. They are well spaced and arranged in a hole 0.1inch deeper than the surface of the flat housing. The user or an assisting person can switch between keyboard mode and mouse mode using a separate key or software controlled. In mouse mode the input unit runs like a mouse simulator (see above), in keyboard mode it realizes the most important inputs like cursors, Enter and so on.  
The input units are fully compatible with standard keyboards and mouses (USB) and can operate simultaneously with the standard  keyboard and mouse.

Mouse simulator with mini joystick    (Maus-Simulator)

prices (article ma-si-01)

Today's communication programs, text processors, teachware or computer games are operated by the computer mouse. To give the users with palsied or other motor co-ordination conditions access to such a software a mouse with a modified handling is required.

Our Mouse Simulators with joystick, keypad or single sensors control the mouse cursor by pressing the 4 or 8 position stick or keypad into the wanted direction (mini or maxi joystick, shaft optional with rubber ball, different diameters of the keys). The mouse speed and dynamic can be adjusted in a configuration mode independent from the operating system of the PC.

Additionally to the left and right mouse keys we emulate the double click and the keylock for drag and drop by separate keys. Just this keying control is very hard to achieve with motor impairment and so we minimise accidental keystrokes.

The keys in the table top housing around the joystick or in the pad are situated in holes that expose and isolate each keytop. The colours and symbols on the keytops suppose a better recognition and selection.

For extremely impaired persons we offer Mouse Simulators with a more robust joystick in a larger case with larger keytops and other forms of Mouse Simulators with trackballs or touchpads too.

Our Mouse Simulators can be attached to the USB port, are recognized as standard mouses and operate with the default mouse drivers under WINDOWS or with the Mac too.

Braille keyboard T8braille

prices (article ts-t8-br)

Generally a blind PC user works with an QWERTY standard keyboard. But, if he has no experiences with such a keyboard or his mechanical braille typer is very handy for him, he can reach a higher efficiency in text input using a braille chord keyboard. Moreover the braille input is necessary in case of Grade 2 braille (stenography). In addition to the braille chords our T8braille is able to produce all the keystrokes to control computer software. On a braille keyboard all the inputs to the computer are composed by pressing one up to 8 keys (8-dot computer braille in a national code). For simple text processing and Grade 2 6-dot-braille is sufficient. Therefore the T8braille can be modified from 8-dot- to 6-dot-braille and to other character sets by switches on the back of the flat tabletop case.

The T8braille is fully compatible with standard keyboards and can operate simultaneously with an optional keyboard via an internal automatic switch. The braille keyboard is also available as one-hand-keyboard for the left or right hand.
