AERIA PEN / DEVELOPMENT HARDWARE SPATIAL INPUT PROTOTYPE

DRAG TO ORBIT · SCROLL TO ZOOM

AERIA / SPATIAL DRAWING + LEARNING

A spatial pen
for learning.

AERIA is a spatial drawing and learning software system. AERIA Pen is the physical interface for exploring what spatial gestures can teach that a mouse, tablet, controller, or conventional stylus cannot do naturally.

V0 CURRENT CHECKPOINT WORKING

A physical spatial pen input prototype for a drawing and learning system.

LEAPPALM XYZ→AERIA IMUQUATERNION→BROWSERVIRTUAL PEN

WORKS TODAY IMPLEMENTED

Physical XYZ tracking and orientation

ROADMAP

Implemented work, current product work, and longer-term research directions.

V0 — PHYSICAL SPATIAL INPUTCOMPLETE

Leap + IMU, physical XYZ and orientation, spatial drawing, snap / close, and core interaction prototypes.
V0.5 — COHERENT LEARNING PROTOTYPECOMPLETE

Unify the product UI and interaction demos. First Learning Mode: WATCH → TRACE → FEEDBACK.
V1 — PORTABLE RESEARCH PENNOW / CURRENT

Webcam tracking with visible coded markers, XIAO IMU, FSR pressure, simple haptics, and an integrated enclosure. Camera-only stable 6DoF is the first milestone.
V2 — TRACKING + INTERACTION REFINEMENTRESEARCH DIRECTION

Optical + IMU fusion, lower latency, pen-tip calibration, pressure calibration, haptic vocabulary, and progressive learning assistance.
V3 — PRODUCTIZATION DIRECTIONRESEARCH DIRECTION

Smaller coded patterns, active optical tracking, headset-camera tracking, and other inside-out approaches.

AERIA LEARNING EMERGING

WATCH→GUIDED→ASSISTED→FREEHAND

Research areas include Ghost Stroke Tutor, spatial trajectory and contour learning, position + orientation + pressure feedback, and pen-specific gestures such as tilt, roll, push / pull, snap, and tactile confirmation.

CURRENT EDGES KNOWN

Leap volume and occlusion remain rough; palm position is not yet calibrated to the true pen tip; orientation jitter is amplified at the tip; closure UX is still being refined; pressure and haptics are not integrated.
