No bulky gloves, no sophisticated camera systems -- just an ultra-thin golden foil on the middle finger. That's all the Dresden researchers need to control a virtual panda with the help of the Earth's magnetic field. When the hand swipes left, towards the magnetic north, the animal also moves in that direction (a). A swipe to the right, makes it go the opposite way (b). When the hand moves towards the middle, the panda moves back slightly towards the left (c).
