1.1. Desktop Computers
Desktop Computer

Desktop computers offer a variety of benefits, they not as portable as a laptops, but can be a more affordable and powerful option, with more features than Laptop computers, therefor ideal for a classroom, office or organisation. There are also a variety of other advantages that Desktops have over Laptop, which include:

– Desktop computers are easier, and less expensive, to upgrade.
– Desktop computers are generally less expensive overall and offer a better overall value.
– Desktop computers generally have larger monitors, which can also be connected to Laptops.

1.2. Laptop Computers

A Laptop, sometimes called a Notebook, is a portable personal computer, which has a Keyboard and screen that can be folded shut for transportation. Laptops are extremely useful for home, working while traveling or for people who have to spend time in bed or hospital and still need to work on their Laptops.

There are numerous advantages to a laptop, but essentially, the choice comes down to portability versus functionality and cost.

While desktop computers are less expensive, more powerful and more user-friendly, there is a lot to be said for being able to work, check emails, chat online, write papers and play video games anytime and anywhere you like. This is particularly true if you are a person with Mobility Impairments.
And besides, laptops these days are highly adaptable, one can easily purchase a more comfortable Keyboard, Mouse or Trackball, a larger monitor and/or an External Hard Drive to store and backup work if space is an issue.

On a Personal Note: I am a C5 Quadriplegic and use a Trackball and wireless keyboard, with “sticky keys”, “key board shortcuts” and “Numb Pad” for finer work.
I often battle with pressure sores and am sometimes laid up in bed for extended periods. I use an Adjustable Bed, which enables me to sit up enough to work in bed with my Laptop on an Over Bed Table, which means that there is no down time in my business.
I honestly consider my laptop to be one of my best buys.

1.3. Tablets and Mountings

Tablets offer many benefits for people with physical disabilities, particularly due to their portability, lightweight design, and touch-based interfaces, which can reduce reliance on keyboards and mice. They support a wide range of built-in accessibility features such as voice control, screen readers, switch access, and customizable touch settings, and can be easily mounted to wheelchairs or used hands-free. Tablets are also convenient for communication, navigation, and everyday tasks, promoting independence and flexibility in different environments.

However, tablets also have limitations compared to desktops or laptops. They typically offer less processing power, smaller screens, and limited multitasking, which can make complex work tasks more difficult. Upgradability is minimal, with fixed storage and memory, and some specialized adaptive software or peripherals may not be fully supported. For users requiring advanced computing, prolonged typing, or high-performance applications, desktops or laptops may provide a more comfortable and efficient long-term solution.

2. Choosing The Right Computer Accessories

Choosing the right computer accessories for people with physical impairments involves matching tools to the user’s strength, mobility, and comfort needs. From ergonomic keyboards to adaptive mice and switch controls, the best choice is one that supports independence, reduces strain, and enhances everyday usability. Please click on the relevant categories listed below to find products that can assist which are available in South Africa.

A. Monitors

All computers comprise of a Monitor, whether they are Desktops or Laptops. A Monitor is an output device that displays information in pictorial form, it usually comprises the display device, circuitry, casing, and power supply. The display device in modern monitors is typically a thin film transistor liquid crystal display (TFT-LCD) with LED back lighting.

Touch screen Monitors are also available for certain types of software, particularly those that do not require pixel-accurate pointing. These monitors use touching of the screen as an input method, items can be selected or moved with a finger, and finger gestures may be used to convey commands. The screen will need frequent cleaning due to image degradation from fingerprints.

There are a variety of different types of Monitors available on the market today, from a diversity of sources. Edit Microsytems also supplies LCD and LED monitors in a wide range of sizes and connectivity options. Their monitor range includes touch screen monitors for special education needs. Contact Edit Microsytems, to find out more about these types of products or to receive a quote.

B. Keyboards & Alternatives

Standard keyboards and a mice are functional ways of interacting with your computer and increasingly other devices like tablets. However, these standard devices can pose difficulties for many people, especially those users with physical, sensory, or cognitive challenges. There are lots of other options available. Being physically comfortable when using your technology is extremely important and extends beyond having a keyboard or mouse that is comfortable to use.

Poor-posture, over-stretching or discomfort can result in aggravating existing conditions or in developing longer-term issues such as Repetitive Strain injuries (RSI’s). Good posture and comfortable working is important for everyone and finding something that works for you is obviously more important in preventing problems than in reaction to them.

The standard computer keyboard is designed to be used with two hands and has a number pad on the right-hand side, which obviously favours right-handed people. Fret not, there are numerous alternatives to the standard keyboard available on the market today including:

i. Ergonomic Keyboards

One-Handed Keyboard

Ergonomic Keyboard are designed to promote a better typing position for your hands and wrists and therefore reduce the chance of strains and discomfort that can ultimately lead to significant issues such as Repetitive Strain Injuries (RSI). Ergonomic keyboards ‘split’ the keyboard in two, placing each half on a curve so your arms are at a more comfortable, relaxed angle when typing.

Some ergonomic keyboards are on a fixed curve. On others, the two halves are hinged in the middle so the angle can be adjusted. On others, the two halves are completely separate and only joined by a connecting wire.

More contoured Keyboards are a further development of the split concept. These place the finger keys into two cupped depressions at shoulder width, with function keys set in-between for use with the thumbs. These fully ergonomic keyboards require very little movement of the arms and wrists and are designed to reduce the risk of RSI. Similar keyboards (with a non-QWERTY layout) are also available for single-handed users, for either left or right-handed use.

An example of these specialised Keyboards, available from Edit Microsystems, is:

The Maltron Single Handed Keyboard (pictured above) was developed as a logical step forward to meet the needs of those who need to type with one hand. The shape matches natural hand movement and the key arrangement minimises finger movement, raising speed and relieving frustration. The special shape and letter layout have been very carefully planned, taking into account the limited number of keys that can be accessed quickly and comfortably.

Word-processing input speeds of 85 words per minute have been demonstrated by operators using Maltron single handed keyboards. The fully ergonomic shape ensures freedom from strain and no RSI type problems have been reported in over 10 years, although all the work is done by one hand! Both Left and Right hand models are designed for “Touch Typing”.

These keyboards have Push-On Push-Off keys for Shift, Control and Alt functions; essential for single hand operation.
Windows keys are also included. This keyboard is USA English and has a USB connector.

v. Smaller, Compact Keyboards

Compact keyboards, as their name suggests, are smaller keyboards. The actual key sizes are quite similar to a standard laptop keyboard and, like a laptop, space is saved by removing the number pad (this can be separate, or some have one that slides out when needed). 
A compact keyboard frees-up desk space and allows you to bring your mouse (or the other things you need) closer to your centreline, which helps to reduce over-extending. As they are smaller, compact keyboards can fit more easily between the arms of a wheelchair and are often more comfortable to use for single-handed users.

Typing Without A Keyboard

As mentioned above, you do not have to use a physical keyboard to control or type on your computer, tablet or smartphone.There are a variety of possible alternatives, including using:

i. On-Screen Keyboard

On-screen keyboards are the way most people now type on tablets and smartphones but are also standard features on most operating systems. Letters can be selected using a touchscreen, a mouse, a switch, or a joystick. Touchscreens use sensors in the screen to track movement and selections and are a very direct and method of interacting with your device.

Tablets and smartphones use touchscreens as well as many laptops. Touchscreen monitors are also available for use with desktop computers. Touch screen Monitors are also available for certain types of software, particularly those that do not require pixel-accurate pointing.
These monitors use touching of the screen as an input method, items can be selected or moved with a finger, and finger gestures may be used to convey commands. The screen will need frequent cleaning due to image degradation from fingerprints.

There are several types available, but you should try to avoid using ‘add on’ touch-screens such as those that fasten over your standard monitor, as these devices lack the accuracy and robustness of modern touch monitors and can cause problems as some learners are more interested in trying to pull them off than using them appropriately. There are a variety of different types of Monitors which are available from various companies in South Africa, such as:

Edit Microsystems can also supply LCD or LED monitors in a wide range of sizes and connectivity options. Their monitor range includes touch screen monitors, which are ideal in a special education needs environment.

An on-screen keyboard, word or pictogram board is used to highlight rows, columns or groups, gradually narrowing-down a selection with each activation of the switch until the desired word or letter is the last option left. Switches work well with cause and effect programmes that require simple choices but are in no means limited to this; skilled operators have few restrictions to what they can do. These types of products are available from various companies in South Africa, including Edit Microsystems who sell the following products:

Big Buddy Button

Uses head movement to control the cursor, which can be done with a wearable headset, or using a camera. With head movement tracking, the cursor is ‘driven’ around the screen in the same way as using a joystick. elections are made using a switch that can be controlled by a puff or bite.
Available from:  Edit Microsystems

Track eye movement, using it to plot the position of the cursor on the screen. Dwelling on a location triggers a ‘click’. This can be used to control programmes as well as to type when used with the on-screen keyboard. Tracking eye movement means that the cursor does not need to be driven around the screen and so is typically much faster than head movement tracking.

D. Mouse Alternatives

The regular Mice/Mouse which is purchased and used with most computers can be difficult to use by young children and persons with Mobility Impairments who have limited use of their hands, including persons with Arthritis and persons with carpal tunnel syndrome.

Trackballs and some other mouse alternatives are also handy when desk space is at a premium and are also easier to use and require less overall effort. They are recommended if you are already suffering from carpal tunnel syndrome and experience pain when moving your forearm.

There are many different types of Alternative Mice/Mouse available, depending on your disability, impairment, or difficulty. It is important to choose one that fits the hand well, feels comfortable and is easy to use, it often takes a little while to get used to using a new type of mouse and can feel a little clumsy at first. Alternatives to the standard mouse include:

i. Ergonomic Mouse

Ergonomic Mice have been designed to reduce muscle strain and decrease discomfort (while using the mouse) associated with a injuries such as carpal tunnel syndrome, arthritis, and tendonitis. Compared to other mice, an Ergonomic Mouse is designed to fit a more natural hand position when being used.

Ergonomic Mice often come in left- and right-handed orientations and in different sizes, to ensure the mouse fits comfortably.
Vertical mice realigning the wrist to a more natural ‘handshake’ position, transferring movement onto the more powerful shoulder muscles.
Adjustable Ergonomic mice are hinged along one side and allow for the mouse to alternate between a flatter more traditional position and the vertical, this encourages a variable wrist position and can help move from a normal mouse to a vertical.

ii. Rollball Mouse

Roll Bar Mice are positioned directly in front of the keyboard and have a ‘bar’ that slides left and right and rolls for up and down movement, eliminating the need to reach for the mouse and reducing unnecessary wrist movements, which can stress your neck, shoulders and elbows. Many of these Roll Bar mice include handy shortcut buttons including double click and copy and paste.

The position of the bar allows it to be operated with your thumbs and keeps your hands on or close to the keyboard. There are various types of these products which are available from companies in South Africa.

iii. Trackball / Roller Ball Mouse

A Trackball or Rollerball Mouse remains stationary with the cursor controlled by rolling a ball with your thumb, fingers, palm, or back of the hand. There is therefor little to no wrist movement, which is ideal for persons with limited hand function who battle to use both the regular Mouse which is sold with a Desktop Computer, or the Mouse Pad used with a Laptop.

A Trackball is basically an upside-down mouse with an exposed protruding ball, which is used to move the pointer. The Trackball has no limits on effective travel and the operator just continues rolling, whereas a mouse would have to be lifted and re-positioned.
Some Trackballs have notably low friction, as well as being made of dense material such as glass, so that they can be spun to make them coast.

The Trackball’s buttons may be differently situated to that of a typical mouse and you get a variety of different types and styles of Trackballs, including cordless ones, which can be handy.
You will need to find one that suits your needs and pocket, as the Trackball is generally more expensive than the normal mouse and more difficult to find in South Africa.

Trackballs are however available from companies such as Edit Microsystems, who also sell some of the following products:

Trackball Mouse

The Logitech Trackman Marble Mouse (pictured at top) has a sleek ambidextrous design that fits either hand comfortably and stays in one place, therefore allowing the user to move the cursor without moving your arm.

Sticky Keys


Sticky Keys is a Windows Ease of Access feature that makes it possible to use keyboard shortcuts or type capital letters without needing to press more than one key at once. Normally, you’d hold down the Shift key while pressing a letter to type a capital or hold down the Ctrl key while pressing ‘S’ to save a document. It’s even trickier if you want to use a shortcut such as Ctrl-Alt-Del or Ctrl-Shift-Esc. 
Sticky Keys makes operating a keyboard with one hand easier, you can press Ctrl, Shift or Alt, let go and then press another key, you should hear a beep if you have the speakers connected. It’s great if you have a Mobility Impairment that affects your arms and can’t press two keys at once.

“I am a C5 Quadriplegic and always use it and find it helps allot. It also makes it easier to use keyboard shortcuts or hold down the Ctrl key while pressing ‘S’ to save a document for example.

You can Setup Sticky Keys when you hit one of your keyboard’s Shift keys five times in a row, this will cause a Window to pop-up, which will ask if you want to enable Sticky Keys. You can also switch it on by going to “Control Panel” then “‘Adjust Computer Settings” then “ease of access” and turn sticky keys on.”
