Abstract:
A user interface apparatus using a speaker to control device operations by utilizing a speaker and a method thereof are provided. The user interface apparatus includes a user input pad that forms at least a portion of the exterior of a speaker and is configured to generate an impact sound wave based on an external impact An impact sound wave recognizer is configured to receive feedback of an output signal output via the speaker and separate a reverse current signal due to the impact sound wave included in the feedback signal. In addition, a controller is configured to analyze a waveform of the reverse current signal separated by the impact sound wave recognizer to recognize a user input pattern, and output a control signal that corresponds to the recognized user input pattern. The device operations of various devices may be controlled by tapping or flicking the exterior of a speaker.
Abstract:
An apparatus and method for recognizing a touch of a user terminal are provided. The method includes retrieving, by a controller, an acoustic wave signal according to an input generated from an exterior and analyzing the acoustic wave signal. In addition, the controller is configured to detect a type kind and strength of the acoustic wave signal and adjust the screen data of the output unit to correspond to the detected type and strength of the acoustic wave signal.
Abstract:
A security apparatus having a force-based touch interface includes: a touch input including a touch plate for a touch input and a force sensor spaced apart at a predetermined distance by a connection member in a direction perpendicular to a touch surface of the touch plate and measuring a pressing force applied to the touch plate at a plurality of measurement points; and a processor configured to recognize directions of a shear force using magnitudes of the pressing force measured by the force sensor, to compare the recognized directions of the shear force with directions of a shear force of a previously registered security code, and to determine whether to disable security according to a comparison result.
Abstract:
A touch input device includes: a touch plate having a first surface facing in a first direction, and a second surface facing in a second direction opposing the first direction; at least one elastic member connected to the second surface of the touch plate, and deformed in at least one of the first direction and the second direction when a touch is applied to the first surface of the touch plate; and a plurality of sensors connected to the at least one elastic member and detecting when the elastic member is deformed to sense the touch. The plurality of sensors are disposed to be inwardly spaced apart from end edges of the touch plate, and output a first signal when a sensor among the plurality of sensors senses that one point of the touch plate is pulled in the first direction and a second signal when the one point of the touch plate is pushed in the second direction, and the touch plate has a plurality of touch areas divided by a plurality of imaginary lines connecting the plurality of sensors to each other virtually.
Abstract:
The present disclosure relates to an apparatus and method for recognizing a user input. The apparatus comprises a sensor configured to sense an acoustic wave signal generated by knocking a surface of a medium, an extractor configured to separate an initial pulse signal from the acoustic wave signal and extract signal characteristic of the separated initial pulse signal, and a controller configured to recognize a knocking gesture based on the signal characteristic extracted by the extractor and generate a corresponding control signal.

Abstract:
A variable mounting sound wave touch pad includes an upper touch pad connected to a microphone to recognize a sound wave. A lower touch pad is spaced apart from the upper touch pad. A plurality of mounting members have one end attached to the lower touch pad and the other end protruding toward the upper touch pad and vary by an actuator which interlocks with the lower touch pad.
Abstract:
A system for controlling a sound wave-based touch recognition interface includes: an auditory user interface (AUI) pad configured to transfer a sound wave, a sound wave recognition member configured to convert the sound wave transferred from the AUI pad into an electrical signal, and an actuator member attached to one side of the AUI pad and configured to be deformed in response to the electrical signal converted by the sound wave recognition member.
Abstract:
A touch screen guide is provided that includes an edge-shaped frame disposed on a surface of a touch screen and both ends of an inside surface of the edge-shaped frame includes first guide grooves. A menu guide has both ends movably inserted into the first guide grooves of the frame, a substantial center is longitudinally provided with a moving space, and upper and lower portions of an inside are provided with second guide grooves. A touch guide includes upper and lower portions movably inserted into the second guide grooves of the menu guide and a substantial center is provided with an insertion space. Accordingly, a user may recognize which button is being operated when touching the touch screen viewing the screen to prevent the touch screen from being erroneously operated, thereby improving the convenience of use and the marketability.
