  • Patent number: 10303303
    Abstract: A combination touch and transducer input system is provided, which facilitates user input into an electronic system with a finger and/or a transducer (e.g., a stylus). The system includes a transducer configured to generate an electric field, and a sensor including an array of electrodes and a controller. The transducer is configured to transmit digital data, such as pen pressure data and switch status data, to the sensor. For example, the transducer comprises electronic circuitry configured to encode the digital data in a signal for transmission to the sensor. The sensor controller is configured to operate both in a touch sensing mode and in a transducer sensing mode. During the touch sensing mode, the controller determines a position of a proximate object (e.g., a finger) by capacitively sensing the object with the array of electrodes.

  • Patent number: 10228781
    Abstract: A resistive force sensor may be configured with two exposed pads, each exposed pad electrically connected to a terminal. When a force is applied to a force applicator, a conductive pad moves into contact with the exposed pads, thus completing an electrical circuit and providing a precise measurement of the point in time when a user has supplied sufficient force to switch the apparatus from one mode of operation to another. In another implementation, two resistive sensors may be disposed above and below portions of a conductive pad with an elastic member disposed between the two resistive sensors. When a force is applied to the force applicator of the apparatus, a differential resistance may be calculated between the two resistive sensors. Since resistive sensors may experience thermal drift due to changes in environmental temperature conditions, the differential resistance between the two resistive sensors allows a temperature-independent measurement of force.

When the first control is selected, a movement vector is calculated based on the input coordinate point and a predetermined coordinate point, and a display area of a virtual space, which is displayed on a display device, is moved. Alternatively, when the first control is selected, the movement vector is calculated based on the input coordinate point and predetermined coordinate point, and an object is moved within the virtual space. When the second control is selected, the object is moved to a position in the virtual space, the position corresponding to the input coordinate point. Then, the display device is caused to display the virtual space within the display area.

  • Patent number: 8711130
    Abstract: A position pointer is provided, which includes a housing having an opening, a rod disposed in the housing such that one end thereof projects from the opening, and a variable capacitor having a capacitance value which varies in response to pressure applied thereto through the rod. The capacitor includes a dielectric member having a first face portion opposite a second face portion, a first electrode section disposed on the first face portion of the dielectric member, a conductive member facing the second face portion of the dielectric member and forming a second electrode section when brought into contact with the second face portion of the dielectric member, and an elastic member coupled with the conductive member and adapted for biasing the conductive member away from the second face portion. A contact area between the conductive member and the second face portion varies depending on the pressure applied through the rod.

  • Patent number: 8493340
    Abstract: The presently disclosed technology teaches using a tilt-sensitive virtual marking implement to render an impression on an electronic presentation device. Further, a bearing measurement and a tilt measurement of the virtual marking implement are made with respect to the surface. The tilt and bearing are then used to vary geometry of an impression profile associated with the physical marking implement as well as an intensity of the rendering. A user may actively vary the impression profile while he or she produces strokes of the virtual marking implement across the surface without changing the physical marking implement selection or switching to a different virtual marking implement. When creating a rendering on a virtual canvas using the virtual marking implement and the surface, a user may wish to vary an orientation of the virtual marking implement so that a corresponding impression profile mimics an impression of a selected physical marking implement.
