• Looking Back on the Process

4
The Problem Statement

• To use a Graphics Tablet as a game play device.
• The users actions using the Graphics Tablet will
  directly affect a characters swinging of a sword
  in a 3d environment.

5
Your Proposed Solution

• Ogre3D as the graphics engine
• While hovering avatar follows pen in pose
  position
• While applying pressure capture direction and
  velocity to calculate a swing
• Ability to switch hands and stances
• Interpolation between strike and pose

6
The Solution You Created

• OpenGL as the graphics engine
• While hovering avatar follows pen in pose
  position
• While applying pressure absolute control of
  swing
• Ability to switch hands
• Interpolation between poses but not strikes

7
Environment

• OpenGL
• SDL
• Standard Windows Libraries
• Tablet Libraries
• Wacom Tablet SDK
• WinTab API
• bbTablet API
• Skeleton Library
• Animadead 2.0
• Maya 6.5

Interaction

• Hovering
• What do we want?
• Avatar follows tablet pointer
• Smooth transition between poses
• What do we need?
• Problems
• How do we do it?

10
Interaction

• Hovering
• What do we want?
• What do we need?
• 5 poses
• UP ---DOWN
• LEFT ---RIGHT
• CENTER
• Problems
• How do we do it?

11
Interaction

• Hovering
• What do we want?
• What do we need?
• Problems
• I want the area of influence on the tablet to be
  round
• Tablet returns values from 0,1
• How do we do it?

12
Interaction

• Hovering
• What do we want?
• What do we need?
• Problems
• How do we do it?
• Create 4 additional Blends per stance
• Blend Each Pose with Center Pose
• Dependent upon radius
• Blend Newly Created Blends
• Dependent upon angle
• Adjust Blend Weight for everything between

• Slash CENTER
• Problems
• How do we do it?

16
Interaction

• Slashing
• What do we want?
• What do we need?
• Problems
• Bad Data
• Transition between slash and hover
• How do we do it?

17
Interaction

• Slashing
• What do we want?
• What do we need?
• Problems
• How do we do it?
• Create 4 addtl poses
• Blend Adjacent poses
• Adjust Blend Weight for everything between

18
Sample Test Cases

• Usability/Playability
• Hovering
• Striking
• Switching hands

19
Test Results

• Hovering
• Greater range of movement
• Striking
• Allow direct control of the swinging. Stop on a
  dime
• Switching hands
• Too sensitive

20
Looking Back

• What conclusions can you derive from this work?
• What exactly did you learn, including positive
  and negative results?
• How would I execute this problem again?
• What are the open problems remaining for this
  project and its related field of study?
• What can be done to extend and perform further
  work on this project?
