    摘要: A touch screen device, an input device, and a control method thereof are provided. The touch screen device includes a channel electrode configured to receive a signal from an input device, a driver circuit configured to apply a drive signal to the channel electrode, a receiver circuit configured to receive the signal from the channel electrode, and a processor configured to control the driver to transmit an input device identification information to the input device such that, when a signal transmitted from the input device is received through the receiver circuit, based on a frequency of the received signal or a pattern of the received signal, the processor determines if the received signal is associated with the input device identification information transmitted to the input device. Accordingly, a touch screen device capable of touch inputting with respect to a plurality of input devices can be provided.

    摘要: A display apparatus capable of being touched plural times by a single user or being used by a plurality of users is provided. The display apparatus includes: a display; a sensor sensing a user touch on the display; and a processor configured to execute a writing function corresponding to a first touch when the first touch is sensed through the sensor and executing a function corresponding to a second touch of a user at a coordinate value at which the second touch is sensed in response to the second touch when the second touch is sensed in a predetermined range of the first touch based on a coordinate value at which the first touch is sensed during a period in which the first touch is input.

    摘要: An electronic apparatus for measuring a frequency of an electromagnetic signal emitted from a coordinate indicating device contacting a sensor pad, and method are provided. The electronic apparatus includes a signal receiving unit that receives the electromagnetic signal, a band-pass filter unit including a pair of band-pass filters that generates a first filtered signal and a second filtered signal by respectively filtering the electromagnetic signal in a first frequency range and a second frequency range corresponding to a center frequency of the coordinate indicating device, and a controller that acquires a frequency value of the electromagnetic signal based on a ratio value between the first filtered signal and the second filtered signal.

    摘要: The disclosure relates to a digital whiteboard, the digital whiteboard including: a display; a first sensor configured to detect a touch position of a writing instrument with regard to a screen of the display; a second sensor configured to obtain an image based on image capturing; and a processor configured to identify a target region, in which a motion is present, in the image by comparing a series of images captured by the second sensor, identify a color of the writing instrument in the identified target region, and display an image comprising the identified color, at a position corresponding to a touch of the writing instrument on the screen of the display.Thus, the color of the writing instrument touching the screen of the display is automatically identified, and the traces of the writing instrument are displayed with the identified color on the screen, thereby giving a user an experience as if the user directly writes with the corresponding writing instrument on the digital whiteboard.
