comfort

The choice of computer mouse is a very individual thing and depends on many factors:

  • How many hours a day you work at your computer?
  • Is your primary computer a desktop, a laptop or notebook or even a tablet; but you won’t be needing a mouse if it is a tablet, will you?
  • How big your hands are.
  • Do you want/need to use wired, wireless or bluetooth?
  • Whether you use the scroll function or not.
  • Do you suffer from wrist pain?

In some of these instances, the cheaper type mouse that comes with your computer will serve your needs adequately, but if you, like me work for about eight hours every day, the comfort and functions of your mouse are particularly important.

On the left below is a photo of the first mouse I paid in excess of $60 for and never regretted it at all. It was comfortable in my largish hands and I didn’t ever suffer any wrist pain even though I worked at my PC sometimes up to 12 hours in a day. The day I dropped it on the tiled floor and broke it was a very sad day for me.

Luckily I was able to buy another different model  but with the same profile within a couple of days. That one too has died lately so I’m looking for a new one, the Kensington mouse on the right below might well be the one since I have had a word in Santa’s ear!

The logitech 2nd from left has served as my laptop mouse for a couple of years – it does look a bit battered, doesn’t it? Very similar profile and quite comfortable. The third photo shows my big hands – imagine my right hand wrapped around one of these tiny mobile models! However, I do carry a retractable one around in my laptop bag, as a backup and the occasions when an extra mouse is needed to test someone’s computer.

 History of the computer mouse

Tracking Technology

.
Did you know that the name mouse is derived from “Manually Operated User Select Equipment”? This makes the argument about whether more than one computer mouse should be called computer mouses or computer mice (as we do for the rodent variety). It seems there has been no absolute ruling and generally computer companies avoid the issue by calling them mouse devices. Probably mouses is technically correct, but it sounds awkward and people tend to use mice for the plural form.
.
The original design for a mouse was mechanical; the mouse had a ball in a compartment underneath and embedded around the edge were some little rollers. These would clog up from the dust and dirt from the user’s desk and needed cleaning to keep the mouse running smoothly (I did this countless times when clients or friends complained that their mouse wasn’t working properly). There were also four sliding type feet that clogged up as well, but these devices were a boon when the alternative was just keyboard shortcuts.
.

Along came optical technology and made our lives so much easier. A small LED on the bottom of the mouse translates the movement of your hand into movement of the mouse pointer. Laser mouse devices work the same way, but using a laser instead af the LED. Laser mice have a higher dpi (dots per inch) which means they are more sensitive. For general users this extra sensitivity is not really needed, but graphic designers and gamers often appreciate the difference and make a laser mouse their choice.

Wired Connectors

.
The early mice (see above) had a serial connector plug, see picture below. Serial ports were the original standard for interfacing any device with any other device on a computer. Later, a smaller 6 pin Mini Din was introduced by IBM on their PS/2 personal computer and this led to the connector type being called PS/2. For many years PC’s had PS/2 connectors for both keyboard and mouse.
.
Some computers still come with two PS/2 ports, but more commonly they just have one, the USB (Universal Serial Bus) being the most common type of interface on all computers, whether PC or Mac. All USB ports look the same, but there is the original USB 1.1 and USB 2.0 which allows much faster (almost 40x as fast) or increased delivery capabilities. The ports are backwards compatible, so you can plug an old USB 1.1 device into a 2.2 port and it will still go.

Wireless

Originally the mouse device was connected to the computer by a cable using one of the technologies above, but nowadays you have the choice (an increasingly common one), to go with wireless. The early hassles of wireless connections seem to have been ironed out and wireless usually works very easily on any platform. Yay! So much more freedom.

.
wireless.
Radio Frequency – this is the most common type of wireless interface. A generic mouse operates on th 27MHz frequency and the mouse is powered by batteries. More expensive models can come with rechargeable batteries or charging docks for the mouse. They may use higher frequencies and have a longer range.

bluetooth.
Bluetooth was useful for lower speed devices like a mouse and was common on early laptops. They are also battery powered and use the 2.4GHz radio frequency to communicate with a receiver/charger supplied with the package or some other Bluetooth adapter...
..aa

RFIDRFID (Rapid Frequency Identification) technology uses radio-frequency electromagnetic fields to transfer data to automatically identify and track tags, which for a mouse is movement. Developed by a company called A4Tech, the mouse must be used in conjunction with the included mose pad, but the advantage is that it is wireless and no batteries are needed.
.

Wheels and Buttons

Nearly all mouse devices nowadays have three buttons, with the middle button also being a scroll-wheel. This scroll wheel is essential in my opinion to navigate up and down your screen and on web pages. Any other buttons, typically on the left hand side for a right handed mouse or on the RHS for a left handed mouse, can be programmed by the user to carry out different functions.

 

Buying a computer mouse

A quick search on eBay will show just what a variety of choice there for buying a new mouse – some are fun, some are fancy, some for serious gamers and some ergonomic models for users like me. So how do you choose?

Narrow down the options with these requirements:

  • Do you want wired or wireless?
  • Do you need laser or will Optical suit your needs?
  • What size – full-sized, medium or small (also called compact,  mini, mobile, laptop etc)
  • PS/2 or USB? USB is more common but if your computer does not have many USB ports, but does have PS/2 ports, using a PS/2 mouse (or keyboard) will leave an extra USB port available for other peripherals.
  • Scrolling – do you need left and right as well as up and down?
  • Buttons – does your work (or play) require advanced features?

A great place to see what is available is on eBay, even when you want to shop locally. The wide variety of mouse devices listed there will give you a good idea of all the functions and help you narrow down your choice.

The fall in value of currencies, while costs continues to rise is causing millions of older people around the world to fear what their life will be like in their senior years. There is so much uncertainty that retirement savings carefully put aside for all those years will no longer be sufficient to provide the expected comfort in later life. Such questions as what would happen if they developed health problems, what if one partner dies and the other is left, what if they could no longer afford to live in their family home.

It is not all doom and gloom. According to USNews Money department writer, Richard Satran in an article published 5th March 2103:

Fear has motivated people to start saving more, but here are two positive ways to upgrade savings

Given a half-decade of economic uncertainty, fear may still be the biggest motivator for retirement saving. The financial crisis inspired people everywhere to save more and hold off on short-term spending. “It shook people out of their complacency and got them thinking, ‘I should save more,'” says Ken Hevert, Fidelity’s vice president of retirement products. “All age groups—young people, too, are showing a tendency to be more conservative.”

New surveys by two leading financial-services companies show how attitudes toward saving have evolved, and highlight a couple of easy steps that can have a big impact on savings.

 These easy steps can be summarized in the following two tips:

“Tip 1: Planning for retirement boosts savings dramatically” – the planning process gives them positive goals for retirement

“Tip 2: Putting eggs in more than one basket produces far higher returns” …. “opening more channels for collecting funds has a positive effect on the amount people save”

Does planning give people a sense of taking control of their lives which helps to overcome the fear factor?

If you’re approaching retirement age and wondering what you can do to enjoy a long and healthy life in your golden years then consider adopting the attitude of a lifelong learner. Most people think of lifelong learning as being confined to academic endeavors however the lifelong learning approach covers all areas of life including spiritual, social, academic and physical.

Lifelong learning is based on an attitude of constantly growing and evolving in various areas of your life. The old saying that whenever anything is not growing it is decaying could be just as true for us as humans. No matter what a person’s age there are great benefits to be gained by challenging yourself in the different areas of your life, physical, mental and self-deveopment.

Physical challenges must be appropriate for your level of fitness, but regular exercise of some kind will leep your body healthier and your brain healthier too. Mental challenges do not have to be academic study, they can be a new hobby or interest, a new caring or chrity venture, more involvement with family. The most growth in personal development will come when you take on something that is currently outside your comfort zone (nasty words those, aren’t they? How we love to stay in our comfort zone, even when it isn’t all that comfortable really).

Lifelong learners live by the motto “you’re never too old to learn” and this attitude is a big part of the reason that people who approach life with this mindset are seen to perhaps live longer but definitely enjoy a better quality of life – is the so-called law of nature known as the “use it or lose it” true?

It does seem to be the case that those who are considerably inactive develop mobility problems as they age, whereas those who are quite active do not develop these mobility problems. A similar effect takes place with anyone who takes no part in any mentally challenging activity or pursuit. After years of mental inactivity Continue reading
