Question 1

1.1

The QWERTY keyboard format became designed by way of Christopher Latham Sholes, who patented it
in 1868 and later sold it to Remington in 1873. The format became created for the following motives:

1. Typewriter Mechanics: Early typewriters had mechanical fingers (typebars) that could conflict or jam
if adjacent keys were pressed in short succession. The QWERTY format became designed to reduce the
probability of those jams through spreading out usually used letter pairs, thereby decreasing the
chances of typebars colliding.

2. Adaptation of Morse Code Operators: Many early typewriter users were telegraph operators who
were accustomed to the Morse code. The QWERTY layout turned into prompted by means of the want
to accommodate those operators, making it less difficult for them to adapt to typing.

3. Ease of Use: The QWERTY arrangement aimed to enhance typing performance by means of placing
frequently used keys within smooth reach. Although no longer the maximum green design by way of
present day requirements, it furnished an affordable compromise given the mechanical constraints and
typing practices of the time.

4. Historical Momentum: Once the QWERTY layout changed into adopted by means of the Remington
typewriters, it have become the usual. As typewriters became extra considerable, typists became aware
of this format, main to its enduring recognition and resistance to alternate even with the advent of
computers.

In precis, the QWERTY format became a sensible technique to the mechanical barriers of early
typewriters and has persisted due to historical inertia and great adoption.

1.2 When designing interfaces, the maximum problematic mistakes that designers could make
include:

1. Lack of User-Centered Design:

Ignoring User Needs: Failing to apprehend and prioritize the desires, choices, and behaviors of the give
up users can bring about an interface that is difficult to use and does now not meet customers'
expectancies.

Over complexity: Creating an interface that is too complicated or cluttered can overwhelm users,
making it difficult to navigate and discover essential facts or functions.

2. Poor Navigation and Information Architecture:

Unclear Navigation: Designing doubtful or inconsistent navigation systems can confuse customers and
make it tough for them to find what they are looking for.
