Abstract
Methods and systems for providing computer implemented services using user input are disclosed. To obtain the user input, a passive human interface device may be used. The human interface device may include any number of magnets that may produce a magnetic field used to discern the user input. The magnets may be mechanically coupled to actuatable elements of the human interface device thereby encoding information regarding actuations of the human interface device into the magnetic field produced by the magnets. The magnetic field may be sensed and used to identify actuations by the user which may indicate input from the user.
