  • Patent number: 10019154
    Abstract: A method, an apparatus and a computer program product for operating items with multiple fingers, adapted to a portable apparatus having a touch screen, are provided. In the method, a first touch operation performed on at least one item displayed on the touch screen is detected. A time of the first touch operation staying on the at least one item is accumulated and determined whether to be over a threshold. When the staying time is over the threshold, an edit mode of the item is entered and a second touch operation performed on the touch screen is detected. Finally, the at least one item is operated according to the first touch operation and the second touch operation.

  • Patent number: 8441377
    Abstract: A method of dynamically adjusting a long-press delay time, an electronic device using the method, and a computer-readable medium are provided, wherein the electronic device has a plurality of keys. When a pressed time corresponding to a key of the electronic device exceeds a long-press delay time of the key, the electronic device executes a long-press function corresponding to the key. In the present method, a plurality of key inputs is first received. Then, the long-press delay time of the key is set according to the input rate related to the received key inputs. Thereby, the electronic device can respond appropriately according to the typing speed of a user, so as to offer the user a smooth operating experience.

  • Publication number: 20130069893
    Abstract: A method of controlling an electronic device, an electronic device and a computer program product using the method are provided. The method includes displaying part or all of a ring and a function image outside the ring on the touch screen while the electronic device is in a user-interface lock state, detecting a user input applied to the function image and/or the ring on or near the touch screen, moving the function image and/or the ring in accordance with the user input, wherein the function image corresponds to an application, transitioning the electronic device to a user-interface unlock state and launching the application if the function image and the ring approach each other within a predetermined distance, and maintaining the electronic device in the user-interface lock state if the function image and the ring do not approach each other within the predetermined distance.

  • Publication number: 20100013778
    Abstract: The present invention relates to a portable electronic device which can be switched between a first mode and a second mode. The portable electronic device comprises a first sensor to detect a touch on the portable electronic device and generate a first signal based on such touch, a second sensor to detect a movement of the portable electronic device and generate a second signal based on such movement, and a processing unit which electrically connects the first sensor and the second sensor. When the portable electronic device is in the first mode, the processing unit switches the portable electronic device to the second mode based on the first and second signals. In addition, the present invention provides a mode switching method that enables the portable electronic device to determine whether to enter or exit from the sleep mode.
