Advanced Interaction Techniques Flashcards
Define: Advanced Interaction Technique
A method that uses complex technologies to allow
users and computers to communicate
Define: 3D Interaction Technique
A method for users and computers to communicate
in a real-world, 3D space
List three broad types of 3D interaction
Navigation
Selection and manipulation
System control
Define: Navigation Technique
An interaction technique that allows the user to move
to a desired position within the virtual environment
List three reasons to travel
Exploration
Searching
Maneuver
What are the six categories of navigation techniques?
Physical locomotion Device-based Steering Selection-based Manipulation-based Scaling-based
What does physical locomotion rely on for travel?
The user’s physical movements
T/F Physical Locomotion usually mimics a natural method of locomotion in the real world
T
List examples of physical locomotion
Walking Redirected walking Seven league boots Walking in place Human joystick
Which physical locomotion applies slight rotations to the user’s movements instead of using a one-to-one mapping?
Redirected walking
Name the physical locomotion: The user physically steps in place to virtually walk in the direction of the steps
Walking in place
Name the physical locomotion: Uses the position of the user relative to the center of the tracked space to create a 2D vector
Human joystick
What is the device-based navigation technique
Use devices that respond to the user’s physical movements for travel
What is the steering-based navigation technique
Allows the user to continuously control the direction of virtual motion
What is the selection-based navigation technique
Allow the user to select a route, a target, or a predefined motion and then automatically moves the user along a path to the destination
What is the manipulation-based navigation technique
Allow the user to use a manipulation technique for travel
What is the scaling-based navigation technique
Change the scale of the world so that a physical movement of one meter can represent one nanometer, one kilometer, or another distance
Define: Selection Technique
An interaction technique that allows the user to choose
one or more objects from a set of available objects
Define: Manipulation Technique
An interaction technique that allows the user to position, rotate, scale, or otherwise modify objects
T/F Often easy to separate selection and manipulation techniques due to manipulation closely following selection
F
List 5 categories of selection techniques
Touching Pointing Occlusion Enclosure Indirect
List 4 categories of manipulation techniques
Hand-centered
Offset-based
Proxy
Indirect
Define: System Control Technique
An interaction technique that allows the user to request the system to perform a function, change the mode of interaction, or change the system state
Define: Symbolic Input Technique
An interaction technique that allows the user to communicate symbolic information (e.g., text, numbers, etc.) to the system
