What does a direct neural interface connect?

The brain to an external device

Electrical appliances to a power source

What is the first step in the process of how brain-computer interfaces work as shown in the diagram?

The patient mentally visualizes the cursor reaching the target

The computer monitor displays the interpreted thought activity

The brain activity is interpreted by computer software

An implanted electrode captures the brain signals

What role does the implanted electrode play in the brain-computer interface process?

It displays the interpreted thoughts on the monitor

It helps in visualizing the cursor's movement

It interprets the brain activity

How is the interpreted brain activity finally represented in the brain-computer interface system?

Through the movement of the cursor on the screen

By the patient's physical movement

By flashing lights on the electrode

What is the primary function of the implanted electrode in brain-computer interfaces as shown in the image?

To receive and relay signals from the brain to robotic limbs

To block brain signals to the muscles

To enhance muscle growth in damaged areas

To visualize hand movements in the brain

According to the diagram, what prevents normal brain signals from reaching certain muscles?

External electrical interference

How does the patient control the robotic arm in the brain-computer interface system depicted?

By mentally visualizing hand movements

By physical movement of the remaining muscles

What is the term used to describe the communication between people and computer systems?

Digital communication interface

What does a menu driven interface allow users to do?

Interact with a computer system through a series of menus

Connect to the internet automatically

What is one of the benefits of using menu driven interfaces?

No need to learn a lot of commands

Needs expert language knowledge

Which of the following is a drawback of menu driven interfaces?

Can be irritating if there are too many menu screens

Intuitive and easy to understand

Requires learning many commands

Why are menu driven interfaces considered ideal for beginners?

Everything is in a logical place/order

They require learning many commands

They use a lot of processing power

What is a benefit of menu driven interfaces in terms of system requirements?

Requires extensive processing power

What is the primary function of voice-driven interfaces as mentioned in the text?

To issue commands to a computer system

Why are voice-driven interfaces considered popular according to the text?

They are natural for people to communicate

They require no physical interaction

They have high-resolution displays

What is one of the benefits of using voice-driven interfaces over traditional keyboard input?

It is much faster than keyboard input

It requires more physical desk space

It increases the risk of RSI (Repetitive Strain Injury)

Which of the following is a drawback of voice-driven interfaces?

Background noise interferes with speech recognition

Easier for people with disabilities

Why might voice-driven interfaces not be suitable for all users?

Users with speech impediments might not be understood

They are universally accessible

They can be used without any power source

They are less natural than typing

What is a privacy concern associated with voice-driven interfaces?

It is difficult to keep data input private as people can hear what you are saying

How can commands be issued on a touch sensitive interface?

By touching the screen with a finger or stylus pen

Which of the following is considered a benefit of touch sensitive interfaces?

Easier hand-eye coordination than mice or keyboards

Dirty screens are difficult to read

Users must be within arm's reach of the display

What is a drawback of using touch sensitive interfaces?

Screen can be easily damaged/scratched

Easier to use as the user simply touches what is seen on the display

No keyboard or mouse is required
