Q31.
What does a metaphor in a virtual reality system involve?

a.

Displaying visual icons and menus.

b.

Using tracking devices to locate and interpret user motion.

c.

Representing computer tasks using a desktop metaphor.

d.

Utilizing a turtle dragging its tail to create pictures.

Discuss
Answer: (b).Using tracking devices to locate and interpret user motion. Explanation:In a virtual reality system, the metaphor goes beyond the display screen. The user is also portrayed within the metaphor, and the system uses tracking devices to locate and interpret the user's motion, not just keypresses or external pointing device movements.
Q32.
Why can metaphors be problematic in the context of growing internationalization of software?

a.

They may portray cultural bias.

b.

They may not apply to specific computer tasks.

c.

They may hinder computer novices from understanding the system.

d.

They may introduce unnecessary complexity into the user-computer interaction.

Discuss
Answer: (a).They may portray cultural bias. Explanation:In the context of growing internationalization of software, metaphors can be problematic because they may portray cultural bias, making it challenging for users from different cultural backgrounds to relate to the metaphor used in the system.
Q33.
Which personal computer introduced the concept of direct manipulation and the desktop metaphor for file management?

a.

IBM PC

b.

Macintosh

c.

Lisa

d.

Xerox Alto

Discuss
Answer: (b).Macintosh Explanation:The Macintosh personal computer, introduced by Apple Computer, Inc. in 1984, demonstrated the inherent usability of direct manipulation interfaces and the desktop metaphor for file management.
Q34.
How does the direct manipulation interface represent files and directories in the desktop metaphor?

a.

As typographical commands on the screen.

b.

As icons representing the underlying files and directories.

c.

As audio feedback through a high-quality sound system.

d.

As rapidly executing user actions.

Discuss
Answer: (b).As icons representing the underlying files and directories. Explanation:In the direct manipulation interface for the desktop metaphor, files and directories are represented as icons, visually representing the underlying files and directories to the user.
Q35.
What is one advantage of using direct manipulation for file management compared to a command line interface?

a.

Direct manipulation interfaces provide more rapid feedback.

b.

Direct manipulation interfaces prevent typographical errors.

c.

Direct manipulation interfaces offer more complex commands.

d.

Direct manipulation interfaces eliminate the need for visual feedback.

Discuss
Answer: (a).Direct manipulation interfaces provide more rapid feedback. Explanation:One advantage of using direct manipulation for file management compared to a command line interface is that direct manipulation interfaces provide more rapid feedback on user actions, making it easier to understand the consequences of actions taken.
Q36.
Why is it impossible to formulate a syntactically incorrect move operation in the pick-up-and-drag style of command in the direct manipulation interface?

a.

Because the desktop metaphor does not support move operations.

b.

Because the user is prevented from making any errors during drag-and-drop operations.

c.

Because direct manipulation interfaces use complex algorithms to avoid errors.

d.

Because drag-and-drop actions inherently create syntactically correct commands.

Discuss
Answer: (d).Because drag-and-drop actions inherently create syntactically correct commands. Explanation:In the pick-up-and-drag style of command in the direct manipulation interface, it is impossible to formulate a syntactically incorrect move operation because drag-and-drop actions inherently create syntactically correct commands for moving files.
Q37.
How does the direct manipulation interface provide continual visual feedback during drag-and-drop actions?

a.

By displaying typographical commands on the screen.

b.

By providing audio feedback through a high-quality sound system.

c.

By showing icons representing the underlying files and directories.

d.

By preventing the user from making any errors during drag-and-drop operations.

Discuss
Answer: (c).By showing icons representing the underlying files and directories. Explanation:During drag-and-drop actions in the direct manipulation interface, continual visual feedback is provided by showing icons representing the underlying files and directories, creating the illusion that the user is working in the world of the desktop.
Q38.
According to Norman and Draper, what does the model-world metaphor in direct manipulation systems create for the user?

a.

The sensation of acting upon the objects of the task domain.

b.

The sensation of interacting with an intermediary between the user and the world.

c.

The sensation of using a complex interface.

d.

The sensation of being disconnected from the task domain.

Discuss
Answer: (a).The sensation of acting upon the objects of the task domain. Explanation:According to Norman and Draper, the model-world metaphor in direct manipulation systems creates the sensation in the user of acting upon the objects of the task domain themselves, leading to direct engagement.
Q39.
In a direct manipulation system, how are input and output expressions related?

a.

They are represented by separate widgets.

b.

They are aggregated together into a single interaction object.

c.

They are not considered important in the interaction framework.

d.

They are displayed separately on the screen.

Discuss
Answer: (b).They are aggregated together into a single interaction object. Explanation:In a direct manipulation system, input and output expressions are aggregated together into a single interaction object, as widgets embody both input and output languages, blurring the distinction between them.
Q40.
What does WYSIWYG stand for in the context of interfaces?

a.

What You Sense Is What You Gain

b.

What You Show Is What You Get

c.

What You See Is What You Generate

d.

What You See Is What You Get

Discuss
Answer: (d).What You See Is What You Get Explanation:WYSIWYG stands for What You See Is What You Get in the context of interfaces, indicating that the representation on the screen closely resembles the final product.
