Home Car Washing Robot Unit, Environmentally Friendly

Home robotics have sure come along way. You can buy a pool sweep to clean your pool and it will float around all day and clean all the leaves out, which is very cool. It is even fun to watch, kind of like watching your clothes wash or the dryer spin at the laundry mat. You can also buy a lawn mover, which once set will mow your lawn all by itself. Now that is cool indeed, it will cut the grass while you drink a beer or two, depending on the size of your middle class neighborhood lawn. Oh it might screw up every once in a while, but that is what you are for, you are the brains of the family and besides it gives you something to complain about; “Those damn robots!”

Then there is the coolest little invention of all; the “cat terrorizing” iRobot “Romba” vacuum. Oh it is sure scary for your cat for about ten minutes. Then eventually becomes your cat’s favorite stalking object as it plays with the thing while it cleans the floor and entertains your cat all day? Your cat never had so much fun attacking anything like this before. Hell, I caught my cat riding around on it. I guess my cat is now too lazy to walk across the house and simply waits until the iRobot Vacuum is headed that way? Go figure and you thought your cat was stupid?

Those are all very fun robotic assistants for the household indeed. But what we need is an environmentally friendly home car washing unit, which washes they car while you watch it go. Now that is what I am talking about. Then you can say; “Hey, you missed a spot!” Now that would be cool, when can I get one of those my car? Think on this in 2006.

On the Importance of Good User Interface Design

It seems obvious, but it’s often ignored. A good user interface design can spell the difference between acceptance of a software product and its failure in the marketplace. If the end-users find the software to be too cumbersome or difficult to understand, then an otherwise excellent product could be doomed to failure. The developer’s goal should be to make the software as professional-looking and easy to use as possible.

Sadly, I’ve found that a great many companiesespecially small or highly specialized software firmspay little attention to the mechanics of good user interface style. “As long as it works, that’s what matters!” seems to be their mantra, with little regard for the inconvenience that this imposes on the user.

Thankfully, that’s not how we operate at our company. Our team of developers invests considerable effort into making out user interfaces as intuitive and foolproof as possible, since we know that this is something our customers would appreciate. I’ve often commended my teammates for recognizing that excellence is worth pursuing.

Going back to the topic I can’t remember how many times I’ve encountered software that was designed to work, but with little regard for ease of use. If the software forces the operator to constantly consult a manual or a cheat sheet, then that’s a pretty good indication that the user interface needs improvement. Similarly, the software should allow the user to perform tasks quickly and efficiently, without sacrificing power and flexibility. This seems intuitive, and yet these considerations are so often lacking.

The sad part is that these shortcomings can often be cured using a few simple guidelines. For example, it helps if the user can enter data using buttons and list boxes, instead of typing it in by hand. It helps if the software provides pop-up dialog boxes, to guide the user along the way. Even the judicious choice of icons and other graphics can turn a steep learning curve into a short and gentle slope.

For that matter, even such trivial matters as spelling and grammar deserve attention. Poorly phrased instructions can severely hinder an operatorand even if they don’t, they do reflect poorly on the developers of that application.

There is much more that can be said about the mechanics of good user interface design, but that’s a topic on which entire book can be (and have been) written. Suffice to say that a company that strives for excellence should pay close attention to the elements of software usability and flexibility. These are critical elements of software excellence, and they are worth pursuing.
