# Touch

Touch command detects touch events in Start tab and outputs following values:

• Position
• Radius
• Force

Touch command supports multi-touch.
The data for each finger (including Apple Pencil) is accessible with the index.
In this document we call this index TOUCH_ID.

# Outputs

# Position

• OSC Address
  • x position: /(deviceUUID)/touch(TOUCH_ID)1,
  • y position: /(deviceUUID)/touch(TOUCH_ID)2
• JSON key
  • x position: touches[(TOUCH_ID)].x
  • y position: touches[(TOUCH_ID)].y

Position is the relative position of touches from the center of the screen.
The range of values is [-1, -1] to [1, 1].

# Radius

• OSC Address: /(deviceUUID)/touchradius(TOUCH_ID)
• JSON key: touches[(TOUCH_ID)].radius

Radius is the radius of touch event in pixel size.

# Force

• OSC Address: /(deviceUUID)/touchforce(TOUCH_ID)
• JSON key: touches[(TOUCH_ID)].force

Force is the force of 3D Touch, where a value of 1.0 represents the force of an average touch.
