The more a feature seems natural to a user, the more effort it usually takes for a programmer to design that feature. Think about the graphical user interfaces (GUIs) of some of the latest mobile devices sold by Apple.

Based on your understanding of the above statement, create a report in a Microsoft Word document to answer the following:

What challenges the engineering team must have faced to make such user-friendly GUIs?

What are two key features that should be included in all mobile devices? For each, suggest a simple algorithm that may power these features.

One way to gather requirements when creating a system from scratch is to observe a worker performing the required activities, note down the steps, and then translate them into requirements. This particular technique is effective because expressing requirements in words is not always simple. As a computer user applies this technique for creating complex features, you need to think of a moderately difficult process.

Write down the steps of the process you selected and translate it into an algorithm.

Explain the criteria for making this series of steps ready to be translated into a code?

You just completed writing an algorithm. An algorithm is an effective method for solving a problem and is expressed as a finite sequence of instructions. An automaton runs on some given sequence or string of inputs in discrete time steps.

Using the previously designed algorithm, translate the algorithm into an automaton. What input needs to be provided? What is the output of the automaton?

Describe the steps you took to translate the algorithm into an automaton.

You have learned about automata in this week. Using the concept of automata:

In your own words describe abstract machines.

Can all machines be described by automata? Why or why not? Discuss.

Do all machines accept states and have state transitions? Why?
