Embodiment Construction
[0054] In view of the deficiencies in the current technology for controlling the user interface according to the user's blowing behavior, in the embodiment of the present invention, a plurality of airflow direction sensors are arranged around the screen of the terminal device to collect airflow direction signals, and correspondingly determine whether the airflow acts on the terminal device. The method of on-screen position (hereafter referred to as airflow source position) has been improved to simplify the algorithm and reduce the use of memory resources.
[0055] In the embodiment of the present invention, an array of airflow direction sensors is arranged around the screen of the terminal device, and the number of airflow direction sensors is not less than 2. The more the number of airflow direction sensors, the more accurate the judgment of the position where the airflow acts on the screen. , the corresponding calculation amount is also larger. Each airflow direction sensor ...

The invention discloses a method and equipment for operating interfaces by utilizing airflows to solve the problems of large occupied resource amount of an internal memory and complicated technological realization in the prior art when a control operation is carried out to the interfaces by utilizing souffle. In the method, an equipment screen is divided into a plurality of zones in advance, and a plurality of sensors capable of sensing the directions of the airflows are arranged around the screen. The method comprises the following steps of: receiving the directions of the airflows reflectedby the screen, sensed by each sensor, and determining the straight paths of reflective positions on the screen from each sensor to each airflow and the intersection point of the straight paths according to the airflow direction sensed by each sensor; respectively calculating the space distance between the intersection point and the feature point of each screen zone and determining the positions of the screen zones corresponding to the smallest space distance on the screen as the reflective positions of the airflows on the screen; and carrying out operation control to an user interface displayed in the screen according to the reflective positions of the airflows on the screen.
Description
technical field [0001] The invention relates to the communication field, in particular to a method and equipment for operating an interface by using airflow. Background technique [0002] In the operating system, the user interface is one of the direct manifestations of human-computer interaction. The operating efficiency of the user interface is directly related to the effect of human-computer interaction. If the user interface operation process is complicated and the operating system responds slowly, it will often reduce the attractiveness of the operating system to users and the usability of the system itself; on the contrary, the simple and effective operation process with high sensitivity will improve user efficiency and enhance user experience satisfaction . Due to the fixed interaction mode of the existing keyboard operation mode, the problem of single user experience has appeared, and even in some environments, it cannot meet the requirements of human-computer inte...
