Fig. 5

(A) Skin-applied 2D sensor as on-skin electronics with directional perception. (B and C) Movie snapshots demonstrating touchless manipulation of a virtual object using our on-skin 2D magnetic field sensor. The hand is turned with respect to the direction of the magnetic field lines of a permanent magnet. This motion of the hand is monitored and the angular position is transformed into the setting of a virtual dial, in turn controlling the light intensity of a virtual bulb (movie S4).
