Problems solved by technology

[0004] Although virtual buttons can make users more convenient when using a mobile terminal with a touch panel, such virtual buttons do not fully meet the needs of users, and too many buttons may obscure the display screen, causing troubles in use
In addition, when a user edits a program, watches a video or plays a game, when the user's finger or stylus touches, it is easy to move out of the sensing range of the virtual key, so that the mobile phone cannot receive the user's instruction, causing user operation troubles. Affect the normal use of the program, and reduce the user experience satisfaction of the mobile phone

Embodiment 1

[0037] refer to image 3 , image 3 A block diagram of a mobile terminal according to Embodiment 1 of the present invention is shown. in particular, image 3 The mobile terminal 1 is shown, and the mobile terminal 1 includes a touch screen 10 with a fingerprint recognition function, a touch recognition module 11 , a fingerprint recognition module 12 , a fingerprint processing module 13 and a storage 14 . The touch recognition module 11 is configured to recognize a finger operating the touch screen 10 . The fingerprint identification module 12 is configured to identify the fingerprint of the finger identified by the touch identification module 11 as the first fingerprint. The fingerprint processing module 13 is configured to compare the first fingerprint with a pre-stored fingerprint, and if the first fingerprint matches the pre-stored fingerprint, execute the button function of the virtual button corresponding to the pre-stored fingerprint. The storage 14 is for the user t...

Embodiment 2

[0055] The block diagram of the mobile terminal of embodiment 2 and image 3 same. The flowchart reference of embodiment 2 Figure 6 . Figure 6 The flow chart shown with Figure 4 The flow chart shown differs in that the Figure 4 After step S103 shown and Figure 4 A step S204 is added before the step S104 shown.

[0056] In step S204, after it is determined that the first fingerprint matches the pre-stored fingerprint, it is further judged whether the area where the virtual button corresponding to the first fingerprint and the pre-stored fingerprint is located overlaps, and if so, step S205 is executed.

[0057] Specifically, for a schematic diagram of a display interface of the mobile terminal 1 in Embodiment 2, see Figure 7 . The user uses the fingerprint as the touch screen 10 with fingerprint identification function to control the object C on the screen of the mobile terminal 1 . Same as Embodiment 1, in this embodiment, four virtual keys 101A, 101B, 101C and 1...

Embodiment 3

[0060] The block diagram of the mobile terminal of embodiment 3 and image 3 same. The flowchart reference of embodiment 3 Figure 8 . Figure 8 The flow chart shown with Figure 4 The flow chart shown differs in that the Figure 4 After step S103 shown and Figure 4 A step S304 is added before the step S104 shown.

[0061] Step S304, after determining that the first fingerprint matches the pre-stored fingerprint, further judge whether the distance between the center of the first fingerprint and the center of the area where the virtual key corresponding to the pre-stored fingerprint is located is less than a predetermined distance, and if so, execute step S305.

[0062] Specifically, for a schematic diagram of a display interface of the mobile terminal 1 in Embodiment 3, see Figure 9 . The user uses the fingerprint as the touch screen 10 with fingerprint identification function to control the object C on the screen of the mobile terminal 1 . Same as Embodiment 1, in t...

Abstract

The invention provides a mobile terminal and a method for preventing faulty operation of a virtual key. The mobile terminal is provided with a touch screen with the fingerprint identification function and touch identification function. The method comprises the steps that a, a first fingerprint for operating the touch screen is collected; b, whether the first fingerprint is matched with a pre-stored fingerprint or not is judged, and if yes, the step c is carried out; c, the pre-stored key function of the virtual key corresponding to the pre-stored fingerprint is carried out. According to the mobile terminal and the method for preventing the faulty operation of the virtual key, through the fingerprint identification technology, the faulty operation generated when a finger of a user moves out of the virtual key can be avoided.

Description

technical field [0001] The invention relates to the field of mobile terminals, in particular to a mobile terminal and a method for preventing misoperation of virtual keys. Background technique [0002] With the development of science and technology, various electronic devices are constantly being introduced. Among them, the touch panel is an important milestone in the development of science and technology. The touch panel can display images and input commands through touch. The touch panel adopts the method of direct sensory input, which can replace the keyboard and mouse, and also create many new technological applications. For example, the touch panel can be used as a display screen of a mobile terminal to watch videos, operate games, run programs, and so on. [0003] In different applications, different virtual buttons are displayed on the screen of the touch panel for the user to click to issue instructions. see Figure 1A to Figure 1C In the mobile terminal 1 shown,...
