The correct answer is: D. Use Joystick
A joystick is a hand-operated lever that pivots on a base and is used for controlling aircraft, vehicles, and other machines. It is a type of pointing device that is often used in video games and other applications where precise control is required.
A tracker ball is a pointing device that is used to control the movement of a cursor on a computer screen. It consists of a ball that is enclosed in a socket and is moved by the user’s hand. The movement of the ball is then translated into movement of the cursor on the screen.
A keyboard is an input device that is used to enter text into a computer. It consists of a set of keys that are arranged in a QWERTY layout. When a key is pressed, it sends a signal to the computer that corresponds to the character that is printed on the key.
A space mouse is a three-dimensional pointing device that is used to control the movement of a cursor on a computer screen. It consists of a ball that is moved by the user’s hand and a set of buttons that are used to select commands.
The best way to move around a 3D environment is to use a joystick. A joystick is a very precise pointing device that allows the user to move the cursor in any direction. It is also very easy to use and does not require any special training.
A tracker ball is a less precise pointing device than a joystick. It is also more difficult to use, as the user must move their hand around the ball to move the cursor.
A keyboard is not a good way to move around a 3D environment. It is not a precise pointing device and it is difficult to use for moving the cursor in a 3D environment.
A space mouse is a good way to move around a 3D environment. It is a precise pointing device and it is easy to use for moving the cursor in a 3D environment. However, it is not as precise as a joystick and it is more expensive.
