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 encode information regarding actuations of the human interface device in magnetic field distributions emanating from the human interface device. The magnetic field distribution may be sensed to identify user input provided by a user of the human interface device. The user input may be used to provide the computer implemented services.
Claims20
A human interface device, comprising:
- a top portion for receiving forces applied by a user, the top portion being adapted to:
- rotate with respect to a bottom portion in response to a first force applied by a user, and
- translate from a first position to a second position with respect to the bottom portion when a second force is applied by the user;
- a permanent magnet positioned to rotate and translate with the top portion, the permanent magnet being adapted to generate a magnet field distribution to encode user input received by the human interface device via the forces applied by the user;
- and
- the bottom portion adapted to be in contact with a surface on which the human interface device is placed,
- wherein the permanent magnet is positioned such that orientations of poles of the permanent magnet change in response to a rotation of the top portion.
