Abstract:
A graphical user interface (GUI) may be displayed on a display unit in an apparatus which may include a tactile sensor unit. When a contact by a user is detected at the tactile sensor unit, a control unit may receive a contact detection signal therefrom. Based on the contact detection signal, the control unit may determine a contact pattern and may then display the GUI corresponding to the contact pattern. The GUI may be displayed and modified depending on the location and pressure of contacts by a user's manipulating fingers. Therefore, a user can manipulate the apparatus without any inconvenience or accidental touches.
Abstract:
An input apparatus including an electronic pen and a terminal having a foldable display unit is provided. An electronic pen generates an ultrasonic signal and an infrared signal. A terminal detects the ultrasonic signal and the infrared signal and calculates coordinate information of the electronic pen based on the received ultrasonic signal and the infrared signal. The terminal determines coordinate information of the electronic pen with respect to the foldable display unit by measuring a folding angle of the foldable display unit.
