MALIANG Magic Pencil
Write in the air. Draw on any surface.
MALIANG works two ways from a single device: in the air as a 6DoF spatial controller, and on any surface as a precise 2D pen. Paired with the SX Hub it turns ordinary screens and tabletops into tactile drawing surfaces, write and sketch as if on paper, with sub-millimeter tip accuracy.
From 3D sculpting and annotation in XR to handwriting and design on a desk, MALIANG is a reference design built to be licensed into OEM devices, the natural input for creative and professional work in the spatial era.
Any shape. Same tiny module.
Everything MALIANG needs fits in the last centimeters of a pencil. Which means the pencil is optional: the same stack rides a ring, clips onto a rifle rail for training, follows a surgical instrument — the tracked object stays essentially unchanged.
IMU + BLE in the body
Inertial sensing rides inside the shaft: fast, fine motion between acoustic updates, clock-synced to the receiver over Bluetooth.
Action button
Select, click, hold — without the line ever leaving the tip.
Ultrasonic emitters
The translucent band is where the pen whispers — emitters the host's microphones, or the SX Hub, can hear. Time of flight does the rest.
Pressure-sensitive tip
Sub-millimeter accuracy at the point itself. The same tip draws in the air and lands on any surface.
