Evaluation of take-over techniques for limited interaction resources
Objectives: Determine the preferred take-
over technique Evaluate the impact on the task
completion performance Evaluate the user acceptance of
proposed take-over techniques
Experimental setup
GUI
Users
Hardware:
Steerable Camera Projector
Microphone headsets
Portable Display Surface
Software:
Speech detector [D. Vaufreydaz]
Conversation modeling [J. Maisonnaisse]
Finger tracking [J. Letessier]
PDS tracking
Drawing application
The task
Collaborative reconstruction of a graph
The User Interface
Experimental conditions
The proposed take-over techniques: None – fixed interface (the reference) Explicit touch-based steering Explicit direct manipulation take-over Implicit voice-based steering
Explicit touch-based steering
Explicit direct manipulation
Implicit voice-based steering
Rules controlling the interface location:• Interface is steered toward
the “main speaker”• Interruptions are ignored• Drawing inhibits vocal steering• Conflicts result in loss of interface
