specific Embodiment approach

[0059] The invention provides an induction keyboard for a portable terminal and a control method thereof, figure 1 It is a block diagram of, for example, the structure of a portable terminal described in the present invention. The portable terminal includes a microprocessor (MPU) 100 , a memory 120 , an inductive keypad 140 , a fully electrically coupled circuit 150 , a display 130 and a communication interface 110 . The display device 130 is used to display characters, menu items and various information. The communication interface 110 can be any device including a transceiver structure, and the user can communicate with other portable terminals or a network through the communication interface 110, for example, the communication interface 110 with a transceiver can communicate with a wireless communication network. Figure 7 A schematic diagram of the connection between the capacitive sensing unit matrix and the complete electrical coupling circuit and the microprocessor cir...

Abstract

The invention provides an inductive keyboard of the portable terminal and the controlling method thereof. At least one inductive cell is set on the keyboard area of the portable terminal and an inductive surface is formed. An inductive object slides on the inductive surface, so as to make the moving track of inductive object generate multidimensional coordinate data through the inductive cell. The microprocessor of the portable terminal processes the multidimensional coordinate data generated by the moving track, and make the multidimensional coordinate data to be converted into a cursor that moves on a monitor of the portable terminal, thus controls an item of menu to roll. A key is pressed to select the desired item of menu. The inductive keyboard of the portable terminal and the controlling method thereof provided by the invention can keep the original outline configuration of the handset and not lose the original function of the handset's numeric keyboard at the same time the rolling, viewing and selecting function of the item of menu is provided.

Description

technical field [0001] The present invention relates to the field of electronic technology, in particular to a user interface device, specifically an inductive keyboard for a portable terminal and a control method thereof. Background technique [0002] With the development of communication technology, mobile phone, as a kind of portable terminal, has become a popular communication tool. With the needs of users, mobile phones are developing towards miniaturization, humanization, diversification, intelligence and informationization. Traditional mobile phones are mainly used for calls, and the requirements for user interface devices are relatively simple. The mobile phone keypad based on the principle of electromechanical switches can already meet the requirements well. This kind of keyboard usually includes "0-9" ten number / letter keys, and several function keys. An elastic cap is arranged under the key, and when the key is pressed, the conductive layer of the elastic cap co...
