Input device and sound output system
An input device includes: a touch device configured to receive a user operation; an actuator configured to apply a vibration corresponding to a drive voltage to the touch device; and a processor. The processor is configured to: apply a first voltage to the actuator to vibrate the touch device with a first vibration in response to a touch-down during a touch operation, the touch-down in which a pressing force of a predetermined value or more is detected from start of touch to the touch device; and apply a second voltage lower than the first voltage to the actuator to vibrate the touch device with a second vibration in response to a touch release during the touch operation, the touch release in which a pressing force of a value lower than the predetermined value after the touch-down is detected.
System and method for detecting and responding to touch inputs with haptic feedback
One variation of a system for detecting and responding to touch inputs with haptic feedback includes: a magnetic element rigidly coupled to a chassis; a substrate; a touch sensor interposed between the substrate and a touch sensor surface; an inductor coupled to the substrate below the touch sensor surface and configured to magnetically couple to the magnetic element; a coupler coupling the substrate to the chassis, compliant within a vibration plane approximately parallel to the touch sensor surface, and locating the inductor approximately over the magnetic element; and a controller configured to intermittently polarize the inductor responsive to detection of a touch input on the touch sensor surface to oscillate the substrate in the vibration plane relative to the chassis.
TOUCH PANEL
A touch panel includes a plurality of first electrodes, a plurality of second electrodes, and a plurality of wirings. Each of the plurality of first electrodes has a first portion formed on a layer different from that on which the second electrodes are formed and intersecting the second electrodes, and a second portion formed on the same layer as that on which the second electrodes are formed, but separated from the second electrode. The second electrode and the second portion of the first electrode are formed on a layer different than the layer where the wiring is formed. The first portion of the first electrode is connected to the second portion through a contact portion formed in an insulating film made of a negative resist between the first portion and the second electrode.
GESTURE DETECTION AND COMPACT REPRESENTATION THEREOF
Techniques are described that may be implemented with an electronic device to detect a gesture within a field of view of a sensor and generate a compact data representation of the detected gesture. In implementations, a sensor is configured to detect a gesture and provide a signal in response thereto. An estimator, which is in communication with the sensor, is configured to generate an elliptical representation of the gesture. Multiple coefficients for the compact representation of the gesture can be used to define the ellipse representing the gesture.
HEAD-MOUNTED DISPLAY AND INFORMATION DISPLAY APPARATUS
To provide a head-mounted display and an information display apparatus that match the intuition of the user and are excellent in operability. A head-mounted display 1 according to an embodiment of the present technology includes a reception unit 12, an image display element 14, and a display processing unit 132. The reception unit 12 receives an operation signal including information on a relative position of a detection target in contact with an input operation surface 21, which is output from the input device 2. The image display element 14 forms an image V1 presented to a user. The display processing unit 132 causes, based on the operation signal, the image display element 14 to display an operation image V10 with an auxiliary image P indicating a position of the detection target being overlapped on the image V1.
METHOD AND APPARATUS FOR CLASSIFYING A TOUCH EVENT ON A TOUCHSCREEN AS RELATED TO ONE OF MULTIPLE FUNCTION GENERATING INTERACTION LAYERS
A system for classifying touch events of different interaction layers includes a touch screen configured to display an interactive element, one or more vibro-acoustic sensors coupled to the touch screen, a touch event detector configured to monitor the one or more vibro-acoustic sensors and to save vibro-acoustic signals sensed by the one or more vibro acoustic sensors, wherein the touch event detector is further configured to detect touch events in which the interactive element is touched by a first or a second finger part of a user, and wherein the touch events result in generating the vibro-acoustic signals, and a vibro-acoustic classifier is configured to classify the vibro-acoustic signals and activate corresponding functions in the different layers dependent upon which finger part is used.
TOUCH DETECTION CIRCUIT, FINGERPRINT MODULE AND CONTROL METHOD THEREOF
A fingerprint module includes a fingerprint sensor, a metal decorative part, a touch detection circuit, and a processing unit. The touch detection circuit generates a first trigger signal when the metal decorative part is touched; the processing unit is connected to the touch detection circuit and the fingerprint sensor; the processing unit generates a finger touch signal when the first trigger signal generated by the touch detection circuit and/or the fingerprint sensing signal generated by the fingerprint sensor is received. The present application also provides a control method of fingerprint module. In the present application, the metal decorative part and the fingerprint sensor are cooperatively used for performing a joint detection and the overall detection range of the fingerprint module is increased, thereby reducing the detection blind area of a finger and improving the detection accuracy of the fingerprint module for realizing a touch detection function.
SYSTEM AND METHOD FOR VARIABLE FRAME DURATION CONTROL IN AN ELECTRONIC DISPLAY
Devices and methods for improving image quality and decreasing power consumption of an electronic display are provided. The electronic device includes a display panel including a plurality of pixels configured to display an image, and to operate at multiple refresh rates. The electronic device also includes a processor configured to instruct the display panel to transition between the multiple refresh rates based at least in part on a blur effective width of the image.
TOUCH SENSITIVE KEYBOARD
Disclosed are keyboards and keyboard switches sensitive to touch, including, hover and pressure. The keyboard switches have transmit and receive antennae that are spaced apart such that no portion of the transmit antenna touches any portion of the receive antenna. The keyboard switches are arranged in logical rows and logical columns such that each of the keyboard switches is associated with one row and one column. Signal emitters are conductively coupled to the transmit antennae for each of the keyboard switches associated with each of the rows, and each of the signal emitters are adapted to cause each of the transmit antennae to transmit one or more source signals. Receivers are coupled to the receive antennae for each of the keyboard switches associated with each of the columns, and each of the receivers are adapted to capture a frame of signals present on the coupled receive antennae. A signal processor adapted to determine a measurement from each frame, corresponding to an amount of the source signals present on the receive antennae during a time the corresponding frame was received. The signal processor further adapted to determine a keyboard switch touch state from a range of touch states based at least in part on the corresponding measurement.
