Core functions for organizing space & interpreting movement:

BOUNDARY MASKING

• Bind cursor movement to screen coordinates
• Bind cursor movement to odd shaped cast members
• Eclipse the effects of object forces

VELOCITY

• Read the input device's instantaneous velocity
• Read the input device's raw movement vector (with or without updating the cursor)

FRICTION

• Dampen linear input interpretation
• Increase linear input sensitivity

ACCELERATION

• Adjust acceleration and deceleration curves
• Read the input device's instantaneous acceleration

PROXIMITY SENSITIVITY

• Turn sprites into gravity wells
• Turn sprites into repellers
• Set the drop-off radii for proximity effects
• Set forces to have unique effects according to input device's relative movement vector
• Constrain and focus input device axes

INERTIA

• Make use of device trajectories in conjunction with other forces, even after a device is released

SPACE WEAVING

• Set bounded spaces to wrap
• Set discontiguous spaces to worm-hole
• Define interdependent object positioning for dynamic calibration
