Explain the special features that an interface would need for a text reading program for a visually impaired student.Choose an application and examine its interface. Describe the target audience for the application. Comment on the suitability of this interface for the target audience. Describe the ways in which this interface could be improved.Use a graphics program to design a drawing screen for a children’s program that is aimed at preschool children. Describe any peripheral devices you would use with this interface. Give reasons for your choices in terms of the target audience.A program is being designed for an interactive gift selection centre in a shop. This selection centre will use a touch screen to allow customers to choose from a range of items selected for various occasions. There will be a main navigation screen with other screens for birthdays, engagements, weddings, Mother’s Day, Father’s Day, Christmas, Easter andbaby gifts. Write a set of design rules to be followed by the screen design team.

Special features for a text reading program for a visually impaired student: The interface would need to have text-to-speech functionality, allowing the text to be read aloud. It should also have high contrast settings for those with partial vision, and the ability to adjust text size. The interface should be simple and intuitive, with clearly labeled buttons and menus. It should also support Braille displays.

Application and its interface: Let's take the example of the Kindle app. Its target audience is anyone who enjoys reading, from children to adults. The interface is quite suitable for the target audience as it allows users to adjust the font size, background color, and brightness for comfortable reading. However, it could be improved by adding a text-to-speech feature for visually impaired users or those who prefer audiobooks. It could also benefit from a more intuitive system for organizing and searching for books.

Designing a drawing screen for a children’s program: The interface

Special Features for a Text Reading Program for Visually Impaired Students:

• Text-to-Speech: This feature converts the text on the screen into spoken words. It helps visually impaired students to understand the content without needing to see it.
• High Contrast Mode: This feature increases the contrast between the text and the background, making it easier for students with low vision to read.
• Screen Magnification: This feature allows users to enlarge the text and graphics on the screen.
• Braille Display: This feature converts text into Braille, allowing students who are blind to read the information through touch.

Application Interface Examination:

Let's take the example of 'Voice Dream Reader', a text-to-speech app. The target audience for this application is people with visual impairments or dyslexia. The interface is suitable for the target audience as it offers customizable speech and reading speed, and supports a variety of text formats. However, the interface could be improved by adding a feature to change the voice tone and adding support for more languages.

Designing a Drawing Screen for a Children’s Program:

Using a graphics program, the drawing screen should be colorful, with large, easy-to-identify icons. The tools should be simple and intuitive, such as a paintbrush, eraser, and color palette. The peripheral devices could include a touchscreen or a stylus for easy drawing. These choices are suitable for preschool children as they are simple to use and understand.

Design Rules for an Interactive Gift Selection Centre:

• Consistency: The design of all screens should be consistent in terms of colors, fonts, and layout.
• Simplicity: The design should be simple and intuitive. Avoid using complex navigation or too many options on one screen.
• Touch-Friendly: As the selection centre will use a touch screen, all elements should be large enough to be easily selected by touch.
• Clear Categorization: Each occasion should have its own screen with clear labels.
• Visual Appeal: The design should be visually appealing with attractive images of the gifts.
• Accessibility: The design should consider accessibility features for people with disabilities.

Special features for a text reading program for a visually impaired student:

• Text-to-Speech: This feature converts the text on the screen into spoken words. This is crucial for visually impaired students as it allows them to understand the content without needing to see it.

• High Contrast Mode: This feature increases the contrast between the text and the background, making it easier for those with some vision to read the text.

• Screen Magnification: This feature allows the user to zoom in on specific areas of the screen, making the text larger and easier to read.

• Keyboard Shortcuts: These allow the user to navigate through the program without needing to use a mouse.

Application: Microsoft Word

• Target Audience: Microsoft Word is designed for a wide range of users, from students to professionals, who need to create, edit, and share documents.

• Suitability: The interface is suitable for the target audience as it is user-friendly and offers a wide range of tools for creating and editing documents. However, it may not be fully accessible for visually impaired users.

• Improvements: The interface could be improved by incorporating more accessibility features, such as a built-in screen reader, better contrast options, and more comprehensive keyboard shortcuts.

Designing a drawing screen for a children’s program:

• The interface should be simple and colorful, with large, easy-to-press buttons.

• Peripheral Devices: A touchscreen or a drawing tablet would be ideal for this interface, as they allow children to draw directly on the screen. These devices are intuitive and easy to use, making them suitable for preschool children.

Design rules for an interactive gift selection centre:

• The interface should be simple and intuitive, with clear instructions.

• The touch targets should be large enough to be easily pressed.

• The navigation should be consistent across all screens.

• The interface should use high-contrast colors to ensure readability.

• The interface should include clear visual cues to indicate which items are selected.
