Accessibility in computing

Since the first versions of Windows, which is still the most popular operating system worldwide, Microsoft has introduced tools to assist users with various disabilities. One of the first examples is the option to magnify a portion of the desk for easy reading. This virtual magnifying glass, appeared almost two decades ago, was one of the first attempts to help people with vision problems read texts with small sources. Today, the flexibility of programs is such that resizing their content is a part as essential as the rest of the functions.

It is also very popular The command through voice.

It was also common to use a faculty called memory, which allowed us to remember phone numbers, birthday dates, and even email addresses. This is no longer necessary, nor normal.

This list of services They provide us with great comfort, and many times it is very positive, especially in an emergency. Also, if we could calculate the magnitude of mental processing that saves this level of assistance, we would surely obtain a considerable result. The expected, therefore, would be for the human being to take advantage of this ability, since unnecessary, to progress, to resolve certain issues that afflicted him in the era of Windows 3.1 and tube TVs. The expected, unfortunately, is far Light years of reality
