Introduction
• Controlled experimental evaluation of a Kinect based user interface.
• 3D object manipulation in virtual environment.
• Two variations - with & without self avatars.
2
Motivation
• Availability of low cost gesture recognition hardware.
• 3D graphics on web platform.
3
The LeapMicrosoft Windows Kinect
Nintendo Wii
Avatars
• Self Avatars
• Earlier studies – Inconclusive results on spatial cognition tasks.
4
Questions
• Does self avatar have observable effect on interfaces for object manipulation in virtual environments on a desktop display?
• Are there strong individual differences in the effect?
5
Experimental task
• Orientation matching 3D object by rotating object in virtual world.
6
Interface - Display Conditions
7
• Sphere Condition
• Self Avatar Condition
* Between subjects design used
Interface – Interaction Methods
8
• Swipe – Rotation along hand motion.
• Twist – Rotation about the wrist.

Experiment Setup
10
• Kinect
• Orientation Sensor
• Wireless Mouse
Result – Completion Time
• No significant difference between sphere and avatar condition overall
11
Result – Completion Time
• Difference as function of gender and video game experience.
12
Gaming experience / Gender ?
13
Results – Manipulation modes
• Difference in manipulation mode as a function of gender/gaming experience
14
Conclusion
• Effect of self avatar on performance of only a subset of users
• Necessary to check for individual differences in performance data
16
Future Research
• Automatic twist/swipe mode detection• Replace orientation sensor with a low cost
mobile device accelerometer• 6DOF task• Stereographic displays• Symmetrical objects• Tactile Feedback• Comprehension vs. Manipulation
