Abstract
A haptic sense rendering apparatus is disclosed that includes a haptic sense rendering unit, a magnet, a coil that magnetically interacts with the magnet and drives the haptic sense rendering unit, and a drive circuit that generates a drive signal for driving the haptic sense rendering unit to emphasize at least one of a drive starting operation and a drive terminating operation and supplies the generated drive signal to the coil.
Claims8
A haptic sense rendering apparatus comprising:
- a haptic sense rendering unit;
- a magnet;
- a coil that magnetically interacts with the magnet and drives the haptic sense rendering unit;
- and
- a drive circuit that generates a drive signal for driving the haptic sense rendering unit to emphasize at least one of a drive starting operation and a drive terminating operation and supplies the generated drive signal to the coil, wherein
- the drive signal generated by the drive circuit includes a basic pulse and an auxiliary pulse that is attached to an edge portion of the basic pulse and the auxiliary pulse is attached to a falling edge portion of the basic pulse and has an opposite polarity with respect to a polarity of the basic pulse.
A method of driving a haptic sense rendering apparatus that includes a haptic sense rendering unit, a magnet, and a coil that magnetically interacts with the magnet and drives the haptic sense rendering unit, the method comprising the steps of:
- generating a drive signal for driving the haptic sense rendering unit to emphasize at least one of a drive starting operation and a drive terminating operation;
- and
- supplying the generated drive signal to the coil, wherein
- the drive signal includes a basic pulse and an auxiliary pulse that is attached to an edge portion of the basic pulse and the auxiliary pulse is attached to a falling edge portion of the basic pulse and has an opposite polarity with respect to a polarity of the basic pulse.
