摘要:
A touch-sensitive input unit includes a base, a touch-sensitive input surface for detecting a touch event thereon, the touch-sensitive input surface connected to and moveable relative to the base, and an actuating arrangement including an elastically deformable substrate between the touch-sensitive input surface and the base, and a piezoelectric patch transducer fixed to the substrate for controlling a bending force on the substrate to control a force on the touch-sensitive input surface by modulating a charge at the patch transducer.
摘要:
Methods and apparatus for providing tactile feedback to a touch-sensitive display comprising detecting a touch on the touch-sensitive display and providing tactile feedback by one or more actuators in response to the touch, wherein tactile feedback is substantially the same regardless of a location of the touch. Tactile feedback may optionally be based on the location of the touch relative to the location of the actuators and may also optionally be based on the force of the touch.
摘要:
A method includes displaying an image of a key on a touch-sensitive display and detecting a touch on the touch-sensitive display at a first location. When the first location is located in a predetermined area related the key, tactile feedback is provided that simulates a characteristic of a physical key. The touch-sensitive display may be part of a portable electronic device.
摘要:
A method of controlling an electronic device having a touch-sensitive input surface includes monitoring the touch-sensitive input surface of a touch event thereon, and modulating a force on the touch-sensitive input surface for causing a first movement of the touch-sensitive input surface relative to a base of the electronic device in response to detection of a touch event on the touch-sensitive input surface. The force is applied by at least one actuator in a single direction on the touch-sensitive input surface.
