------------------------------------------------ Modern HCI emphasizes user-centered design, where the design process is centered around the users.

Using the general user-centered activities described in Chapter 2, propose a design for a software prototype for one of these user groups:
- Elderly
- Children
- Disabled people
- Professionals

Your software prototype can be on any platform—web, mobile, stand-alone, wearable, etc. Your tasks include:

1. **Name and Objective**
- Name your software prototype.
- Explain its aim, objectives, and the problem it is designed to solve.

2. **Collect Requirements**
- Gather requirements from potential users via an online survey and interviews or observations based on your chosen user group.
- Collect a minimum of 10 survey responses and two sets of interview or observation data.

3. **Present Requirement Results**
- Analyze the needs, tasks, and functionality based on your collected data.
- Highlight any surprising suggestions or feedback from users, including metaphors if any.

**Designing Process**
Prepare for prototyping by including a drawing and description of each UI design. Describe how the prototype will look and work based on your analysis and findings from Question One. Your tasks include:

1. **Preparing the Conceptual Design**
- Present at least three model layouts that describe abstractly what the users require, how the problem can be solved, and what users can do with the prototype.
- Include interdisciplinary knowledge from Chapter 1 in your conceptual design. This can be achieved with simple sketches.

2. **Preparing the Concrete Design**
- Translate the conceptual design into detailed designs including colors, sounds, images, menus, icons, etc.
- Consider concrete design issues discussed in Chapters 7 and 12. Use any familiar visual programming tools.

**Prototyping**
Prepare the interaction design of your proposed concrete design from Question Two. Your tasks include:

- Provide the behavior as well as the look and feel of your designs, allowing potential users to interact and navigate with the UI during prototype evaluation.
- The prototyping process should not aim to achieve a fully functional product.
- Use any visual programming tool to create this. Include each screenshot with a description of the function, its previous and subsequent state, and highlight UX design practices used to prevent errors.
- Refer to UX design patterns discussed in Chapter 13.

Submit a 2-minute video presentation on the prototype interaction to complement your screenshots.

**Evaluation**
Determine the usability and acceptability of the product based on UX criteria:

- Choose a minimum of 3 potential users, preferably those interviewed earlier or involved in your product requirement survey.
- Conduct a User Acceptance Test (UAT) and review feedback based on:
- Average subjective satisfaction related to its aim and objectives.
- Number of both familiar and unfamiliar metaphors/details to users.
- Number of confusing actions/functions/inputs/outputs for users.
- Any new suggestions or feedback from users for improvement.
