## Background
CROSS-REFERENCE TO RELATED APPLICATION(S) AND CLAIM OF PRIORITY
This application is a continuation of U.S. patent application Ser. No. 13/179,244, filed Jul. 8, 2011, now U.S. Pat. No. 8,588,809 B2 entitled “APPARATUS AND METHOD FOR OPERATION ACCORDING TO MOVEMENT IN PORTABLE TERMINAL”, which claims benefit under 35 U.S.C. §119(a) of a Korean patent application filed in the Korean Intellectual Property Office on Jul. 8, 2010 and assigned Serial No. 10-2010-0065709, the contents of which are incorporated herein by reference.


TECHNICAL FIELD OF THE INVENTION
The present invention relates to an apparatus and method for sensing when a user raises a portable terminal using an acceleration sensor and a touch sensor, and making the portable terminal transition to a wake-up state and a hot key menu access activation state.
BACKGROUND OF THE INVENTION
When a portable terminal is in a sleep mode or lock mode state, in order to wake up the portable terminal, the conventional art has performed the following operations.
First, in a flip type portable terminal, it wakes up when the portable terminal is flipped open or a predefined button of the portable terminal is pressed.
In a slide type portable terminal, it wakes up a cover is slid out or a predefined button of the portable terminal is pressed.
In a bar type portable terminal, it wakes up a hold key is pressed for a predetermined time.
Among these, unlike the flip type or slide type portable terminal, the bar type portable terminal could not intuitively forward its own current state to a user unless the user pressed a hold key.
However, this method has a problem of causing an inconvenience in that a user should directly press and hold a hold key, and also has a problem of not being capable of obtaining a prompt feedback from the portable terminal because the user just cannot use a hot key of the portable terminal.
Furthermore, there is a problem in that this method is in contraposition to reducing the number of buttons.

DETAILED DESCRIPTION OF THE INVENTION
FIGS. 1 through 3, discussed below, and the various embodiments used to describe the principles of the present disclosure in this patent document are by way of illustration only and should not be construed in any way to limit the scope of the disclosure. Those skilled in the art will understand that the principles of the present disclosure may be implemented in any suitably arranged wireless communication system.
Below, embodiments of the present invention provide an apparatus and method for operation according to a motion in a portable terminal.
FIG. 1 is a schematic diagram of a portable terminal according to an embodiment of the present invention.
Referring to FIG. 1, an acceleration sensor 100 determines acceleration according to a motion of the portable terminal and returns a determination value. Touch sensors 110 are provided at both sides of the portable terminal and sense a user's touches. In the present disclosure, an operation of a user raising the portable terminal to look at the screen of the portable terminal is referred to as a grip.
FIG. 2 illustrates a process in a portable terminal for waking up based on detecting a movement according to an embodiment of the present invention.
Referring to FIG. 2, a touch sensor of the portable terminal determines a touch sensor value (block 210).
When a touch is detected (block 220), the portable terminal controls an acceleration sensor to determine acceleration and determines a movement angle of the portable terminal according to the determined acceleration value (block 230). The angle determination using the acceleration sensor can use an existing algorithm.
If the determined angle belongs to a grip zone (block 240), the portable terminal determines that a user raises the portable terminal, and transitions to a wake-up state (block 250). In an embodiment, the portable terminal may also consider the acceleration and movement path.
Here, the determined angle belongs to the grip zone when the angle (e.g. orientation angle, movement angle, and such) of the portable terminal belongs to an angle range associated with a user raising the portable terminal (e.g. a range of motion, movement path, and such), and the grip zone represents an angle range of +/− in a state of holding the portable terminal erect (e.g. within a threshold from a set angle or orientation at which the portable terminal is to wake up from a sleep state) and can change according to a user's definition and an experiment value.
When the touch does not occur (block 220) or the determined angle does not belong to the grip zone (block 240), the touch sensor of the portable terminal returns to block 210 and waits for a touch to be detected.
FIG. 3 is a block diagram of a portable terminal according to an embodiment of the present invention.
Referring to FIG. 3, the portable terminal includes a modem 310, a controller 320, a storage unit 330, an acceleration sensor 340, and a touch sensor 350.
The modem 310, a module for communicating with other devices, includes a wireless processor, a baseband processor and so forth. The wireless processor changes a signal received through an antenna into a baseband signal and provides the baseband signal to the baseband processor. And, the wireless processor changes a baseband signal from the baseband processor into a wireless signal such that it can transmit the baseband signal on an actual wireless path and transmits the wireless signal through the antenna.
The storage unit 330 may be a memory that stores a program for controlling a general operation of the portable terminal and temporary data generated during program performance.
When the portable terminal moves, the acceleration sensor 340 determines and outputs an acceleration value for the motion.
The touch sensor 350 indicates when a touch is sensed.
The controller 320 controls a general operation of the portable terminal. For example, the controller 320 processes and controls voice calls and packet communications. In an embodiment, the controller also controls the acceleration sensor 340 and the touch sensor 350 according to the present invention.
When the controller 320 detects that a touch occurs through the touch sensor 350, the controller 320 controls the acceleration sensor 340 to determine acceleration, and determines an angle of the portable terminal using the determined acceleration value. The angle determination using the acceleration sensor can use an existing algorithm.
If the determined angle belongs to the grip zone, the controller 320 determines that a user raises the portable terminal, and transitions to a wake-up state. According to an embodiment, the determined angle belongs to the grip zone when the determined angle of the portable terminal belongs to an angle range associated with a user raising the portable terminal. The grip zone represents an angle range of +/− in a state of holding the portable terminal erect (e.g. within a threshold from a set angle or orientation at which the portable terminal is to wake up from a sleep state) and can change according to a user's definition and an experiment value.
When the touch does not occur or the determined angle does not belong to the grip zone, the controller 320 waits until a touch is detected by the touch sensor 350.
Embodiments of the present invention can be used for allowing a user to wake up a portable terminal or enter a hot key menu without pressing a key of the portable terminal.
Although the present disclosure has been described with embodiments, various changes and modifications may be suggested to one skilled in the art. It is intended that the present disclosure encompass such changes and modifications as fall within the scope of the appended claims.
