20130321290 | METHOD AND APPARATUS FOR SENSING TOUCH INPUT - There are provided a method and an apparatus for sensing a touch input. The method of sensing a touch input includes selecting at least a portion of a plurality of nodes in which a sensing signal is generated by a touch input, defining a node group according to the plurality of selected nodes, generating two or more first sub-node groups by dividing a plurality of nodes included in the node group, based on a first axial direction, and determining a first touch vector of the node group by calculating centric coordinates of the respective two or more first sub-node groups. | 12-05-2013 |
20130321291 | ELECTRONIC APPARATUS AND OPERATING METHOD THEREOF - There are provided an electronic apparatus and an operating method thereof. The electronic apparatus includes: at least one mechanical button unit receiving a mechanical button input from a user; a touch screen receiving a touch input from the user; and a control unit detecting a first input signal generated from the at least one mechanical button unit to generate a first control signal and detecting a second input signal generated from the touch screen to generate a second control signal, wherein the control unit generates a third control signal different from the first control signal when the first input signal and the second input signal are simultaneously detected. | 12-05-2013 |
20130326395 | METHOD OF UNLOCKING TOUCH SCREEN AND ELECTRONIC DEVICE USING THE SAME - There are provided a method of unlocking a touch screen and an electronic device using the same. The electronic device includes: a display displaying a locked screen image in a screen locked state; a touch screen to which a touch is input; and a controlling unit unlocking the screen locked state when a first touch event continued for a first preset time or longer in the screen locked state and a second touch event generated within a second preset time after the first touch event has ended are sensed. | 12-05-2013 |
20140085208 | TOUCHSCREEN DEVICE AND ELECTRONIC DEVICE USING THE SAME - There are provided a touchscreen device capable of preventing a typing error of a touch keyboard, and an electronic device using the same. The touchscreen device includes a display unit outputting a keyboard touch region including a touch keyboard, a touchscreen to which a touch is made, and a control unit controlling the display unit to output an expanded keyboard having a preset shape by expanding a touch region of a first touch when the first touch is sensed in the keyboard touch region, wherein the first touch is a floating or hovering touch. | 03-27-2014 |
20140145975 | TOUCHSCREEN DEVICE AND SCREEN ZOOM METHOD THEREOF - There are provided a touchscreen device and a screen zoom method thereof, the touchscreen device including a panel unit to which a touch is input, a control unit generating a zoom signal according to a line touch input to the panel unit and having a predetermined length, and a display unit enlarging or shrinking a screen according to the zoom signal and outputting the screen. | 05-29-2014 |
20140168112 | TOUCH SENSING METHOD AND TOUCH SENSING APPARATUS - There are provided a touch sensing apparatus and a touch sensing method. The touch sensing method includes: obtaining sensed data from a touchscreen and a touch key; | 06-19-2014 |
20140168171 | TOUCH SENSING DEVICE AND TOUCH SENSING METHOD - There are provided a touch sensing device and a touch sensing method, the touch sensing device including a sensing circuit unit detecting a plurality of changes in capacitance generated in a panel unit, a signal converting unit generating a plurality of pieces of sensing data for determining a touch input from the plurality of changes in capacitance detected by the sensing circuit unit, and an operating unit determining the touch input based on the plurality of pieces of sensing data, wherein the operating unit corrects a coordinate of the touch input by applying a predetermined correction value when it is determined that the coordinate of the touch input is included in an edge region of the panel unit, and sets different correction values according to a touch area of the touch input included in the edge region. | 06-19-2014 |
