Magnetic Sensor and Virtual Dimmer (IMAGE) Helmholtz-Zentrum Dresden-Rossendorf Caption Controlling virtual light bulbs without touching them -- HZDR's ultrathin electronic magnetic sensor makes it possible. Depending on the fields of a permanent magnet, the movement and the position of the hand, on which the sensor is attached like a second skin, are translated onto a virtual scale that then controls light intensity.
