DETAILED DESCRIPTION OF THE EMBODIMENTS
The technical solution according to the embodiments of the disclosure will be described clearly and completely in conjunction with the drawings hereinafter. Apparently, the described embodiments are just a few rather than all of the embodiments of the disclosure. All other embodiments obtained by those skilled in the art based on the embodiments of the disclosure without any creative work will fall within the protection scope of the disclosure.
To understand the invention comprehensively, many specific details are mentioned in the following description. Those skilled in the art should comprehend that the invention may be implemented without these specific details. In other embodiments, well known methods, processes, components and circuits are not described in detail, to avoid unnecessary obscure of the embodiments.
A First Embodiment
A flow chart of a method according to the first embodiment of the disclosure is shown FIG. 1. A brightness adjustment method is provided, applied to an electronic device such as cell phones, PDAs (Personal Digital Assistants), notebook computers, tablet computers and media players. The electronic device includes a touch sensitive display and a designated physical button. The method includes steps S101-S103.
In step S101, a click from a user on the designated physical button is detected. The designated physical button may be any physical button on the electronic device. In the embodiment or other specific embodiments of the invention, preferably, the designated physical button may include a volume adjustment button.
The electronic device generally has a function of playing audio or outputting audio, accordingly the physical button for volume adjustment, i.e., the volume adjustment button is provided. Taking the cell phone as an example, the volume adjustment button usually includes two separated “add” and “subtract” keys or a single key (referred to as “add and subtract” button). The click on the “add and subtract” button defaults to volume adjustment, through which related volume of the system or application may be adjusted. The function of the “add and subtract” button may be redefined. Thus, the “add and subtract” button may be added the function of brightness adjustment, or the “add and subtract” button is a multifunction button for simultaneous volume and screen brightness adjustment.
In step S102, if the click is detected, a designated panel is displayed on the touch sensitive display, where the designated panel includes a brightness adjustment panel of the touch sensitive display. When the user clicks on the designated physical button, e.g., presses one of the add and subtract keys, the brightness adjustment panel for adjusting the brightness of the display is displayed on the display, so that the user may perform brightness adjustment. A virtual button only appears at a specific location at a specific time in a specific application, and cannot be activated at any time, thus its response level is low. Thereby, the physical button instead of virtual button is adopted in the invention, and compared to the virtual button, the physical button does not vary with the applications, has a fixed location, may be controlled at any time, and possesses a higher response level.
In the embodiment or other embodiments of the invention, preferably, the step that the designated panel is displayed on the touch sensitive display (where the designated panel includes a brightness adjustment panel of the touch sensitive display), includes: querying current brightness information of the touch sensitive display, and displaying a brightness adjustment bar of the touch sensitive display on the touch sensitive display based on the brightness information. The brightness adjustment panel may be a brightness adjustment bar, horizontally or vertically, able to be slid back and forth in the corresponding direction and display current brightness values or brightness percentages. In addition, in some embodiments of the invention, the brightness adjustment panel may be in other forms, such as a dial with figures, an input box for numbers, and a select box for numbers and so on, and these forms which may be used here do not depart from the spirit and protection scope of the invention.
In step S103, the brightness of the touch sensitive display is adjusted based on gesture operation of the user on the brightness adjustment panel. Specifically, the brightness value which the user intends to input may be obtained based on user gestures on the touch screen such as dragging, sliding, toggling, and clicking, thus the brightness of the touch sensitive display is adjusted.
In addition, to take into account user's habit and ensure that the user may still use the volume adjustment button to adjust the volume, the conventional volume adjustment option may be also activated by clicking the volume adjustment button, i.e., panels for volume adjustment and brightness adjustment may pop up simultaneously. That is, in the embodiment or other specific embodiments of the invention, preferably, the designated panel may further include a volume adjustment panel; accordingly, the method may further include, after displaying the designated panel on the touch sensitive display:
adjusting the volume of the electronic device, based on gesture operation of the user on the volume adjustment panel and/or operation of the user on the volume adjustment button. That is, the user may adjust the volume through clicking the “add and subtract” button or adjust the volume through the touch screen according to his habit. Alternatively, the function of adjusting the volume through clicking the “add and subtract” button may be kept unchanged, but the volume adjustment panel is not activated, and only the brightness adjustment panel is activated.
In addition, in the embodiment or other specific embodiments of the invention, preferably, the method may further include, if the click is detected:
notifying the current application to process the click; and
if the current application does not process the click, proceeding to a subsequent step.
The volume adjustment button is redefined in many programs, e.g., the “add and subtract” button may be given a function of zoom in and out on the map in a navigation program, thus requirements of the current application may be met first. In a case that the application does not respond to the click on the designated physical button, the subsequent step such as displaying the brightness adjustment panel is executed.
In implementation, when the user presses the volume adjustment button, the system notifies the current application to respond to it first. If the current application does not respond to it, the system notifies a Audio Service to adjust the system volume by default, and the Audio Service notifies a UI (user interface) service to display the volume adjustment panel on the interface. When the volume adjustment panel is initialized, the volume adjustment bar is displayed. Meanwhile the current screen brightness is queried from system settings, and the brightness adjustment bar is displayed beside the volume adjustment bar based on the brightness value provided by the system. The user may change the position of the brightness adjustment button through a touch operation. Accordingly the brightness adjustment bar changes the current brightness of the display through a Power Service (power service) based on the position of the adjustment button, and a new brightness value is stored in the system settings at the same time.
In the embodiment or other specific embodiments of the invention, preferably, the method may include, after displaying the designated panel on the touch sensitive display:
if no operation of the user is detected in a designated duration, the designated panel is closed. A volume slider and a brightness slider may disappear automatically if no operation is performed on the screen in a few seconds.
