Design and Implementation of Virtual Roaming Control Method Based on Pen Tablet

Table 2

Correspondence between pen-tablet signal data and virtual roaming action.

Type	Roaming action	Tablet signal data
The ground roaming	Walking	Position coordinate information, the pressure value
	Running	Position coordinate information, the pressure value
	Jumping	Pressure-sensitive pen button signal
	Perspective rotation	Tilt value of the pressure-sensitive pen
	View zoom	Tablet center touch ring
The air roaming	Free displacement	Position coordinate information, pressure value, tilt value, side button of the pressure-sensitive pen, sensing distance
	Acceleration and deceleration	Tablet button signal
	Perspective rotation	Pressure-sensitive pen button signal
	View zoom	Tablet center touch ring

Note. We can optionally switch the first-person and third-person perspectives for the ground roaming and the air roaming.
