1. Technical Field
The present disclosure relates to a touch device and a control method thereof.
2. Description of Related Art
a-1b are schematic operation interfaces of a conventional touch device 1. The touch device 1 can be a smart phone, a tablet computer, or the like. For example, when a user of the touch device 1 needs to answer a call, the user may need to operate a slide bar X displayed at a bottom of a display screen to answer the call. However, it is inconvenient for the user to operate the slide bar X of
Therefore, what is needed is a touch device and a control method that can overcome the described limitations.
a-1b are schematic operation interfaces of a conventional touch device.
The disclosure is illustrated by way of example and not by way of limitation in the figures of the accompanying drawings in which like references indicate similar elements. It should be noted that references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references mean “at least one.”
Reference will now be made to the drawings to describe embodiments of the present disclosure.
The lengths of the first and third side surfaces 111, 113 are longer than the lengths of the second and fourth side surfaces 112, 114. The rear surface 116 faces the front surface 115. The touch display screen 12 is received in the front surface 115.
The touch display screen 12 displays graphics, receives contact operations from a user, and executes corresponding functions based on the received contact operations. The touch display screen 12 displays an operation interface (not labeled). The operation interface comprises at least one shortcut mark A. When the at least one shortcut mark A is operated on, the touch device 10 executes a corresponding function. In one embodiment, the at least one shortcut mark A is a slide bar.
The main control unit 21 controls the touch device 10 to display graphics, play video, communicate with other devices, and outputs control signals to the input unit 22, the display control unit 23, the data storage 24, and the detection device 25. The input unit 22, the display control unit 23, the data storage 24, and the detection device 25 operate based on the control signals. In one embodiment, the main control unit 21 is a central processing unit (CPU).
The input unit 22 determines locations of the touch display screen 12 that are touched and outputs corresponding sensing signals to the main control unit 21.
The display control unit 23 outputs image data to the touch display screen 12 based on the control signals. The touch display screen 12 displays images based on the image data.
The main control unit 21 generates information (hereinafter “holding information”) based on how the touch device 10 is held by the user. In one embodiment, the holding information comprises first information, which indicates whether the touch device 10 is held in the landscape orientation or the portrait orientation, and second information, which indicates whether the touch device 10 is held by a right hand, a left hand, or both the right and left hands. In the embodiment, the detection device 25 comprises a first contact detection unit 251, a second contact detection unit 252, a third contact detection unit 253, a fourth contact detection unit 254, a fifth contact detection unit 255, and an orientation detection unit 256. The first through fifth contact detection units 251-255 and the orientation detection unit 256 detect whether the touch device 10 is held by the left hand, the right hand, or both hands in the landscape orientation and the portrait orientation, and output detecting signals to the main control unit 21.
The data storage 24 stores first corresponding relations between the detecting signals outputted from the detection device 25 and the holding information. The data storage 24 further stores second corresponding relations between the holding information and display locations of the at least one shortcut mark A. The data storage 24 can be an EPROM, EEPROM, or Flash ROM.

The orientation detection unit 256 is located between the enclosure 11 and the touch display screen 12, detects whether the touch device 10 is held in the portrait orientation or the landscape orientation, and selectively outputs a sixth detecting signal or a seventh detecting signal to the main control unit 21 based on the detection. When the orientation detection unit 256 detects that the touch device 10 is held in the portrait orientation, the orientation detection unit 256 outputs the sixth detecting signal to the main control unit 21. When the orientation detection unit 256 detects that the touch device 10 is held in the landscape orientation, the orientation detection unit 256 outputs the seventh detecting signal to the main control unit 21.
The first, second, third, fourth, and fifth contact detection units 251, 252, 253, 254, 255 can be resistive touch devices, capacitive touch devices, or other appropriate touch devices. The orientation detection unit 256 can be an accelerometer, a gravitation sensor, or other appropriate device for detecting the landscape and portrait orientations of the touch device 10.

In step S101, when the touch device 10 is powered on, the detection device 25 detects a number of points of contact of sides of the touch device 10, detects whether the touch device 10 is held in the landscape orientation or the portrait orientation, and outputs the corresponding first through seventh detecting signals to the main control unit 21 based on the detections.
In step S103, the main control unit 21 generates the holding information, which indicates how the touch device 10 is held, based on the first through seventh detecting signals.
In step S105, the main control unit 21 adjusts the display locations of the at least one shortcut mark A based on the holding information.
The touch device 10 dynamically adjusts the display locations of the at least one shortcut mark A according to the holding information making the touch device 10 of the present disclosure more convenient to use.
In alternative embodiments, the fifth contact detection unit 255 can be omitted, such that only the first through fourth contact detection units 251-254 are used to detect the number of points of contact contacted by the user.
It is believed that the present embodiments and their advantages will be understood from the foregoing description, and it will be apparent that various changes may be made thereto without departing from the spirit and scope of the present disclosure or sacrificing all of its material advantages.
