AR Tangible Brush

Also known as Relative-Aligned Tangible Brush

Tangible Brush moved into an AR headset: the lasso is drawn on the tablet and swept through the data by moving the tablet, while the headset shows the data and a virtual tablet in 3D, either at the real tablet's position or driven by relative motion from afar.

How it works

With a HoloLens 2 and a VICON-tracked Galaxy Tab S4. Three mappings were studied: the virtual tablet coincides with the real one (NA); it moves with relative motion and the same orientation (RA); or it moves with clutched relative motion in its own frame (RF). Constrained sweeps along the normal and Boolean AND, OR and NOT are kept. Study 1 (18 participants): RA was preferred, RF was slightly more accurate and NA was least liked. Study 2 (18 participants): RA against the original 2D-screen version had similar time and accuracy but clearly lower workload, and participants used unconstrained 6 DoF sweeps more in AR.
