Embodiment

[0019] like figure 1 As shown, the navigation method of the focus element in the man-machine interface in this example is implemented in the following steps:

[0020] (1) Establish a data structure: for the coordinates and height and width data of elements, establish a data structure for maintaining element coordinates and height and width;

[0021] (2) Fill the data structure and establish an element management queue object: traverse all acceptable focus elements, fill the obtained coordinates and height and width data of each element in the data structure, and establish an element management queue object;

[0022] (3) Wait for the navigation event to be triggered;

[0023] (4) Set the return value to the current focus element: when the focus navigation event is triggered, it enters the processing flow, and the final return value of the processing flow is the result of a navigation event. First, set the return value to the current focus element;

[0024] (5) Determine the s...

Abstract

The invention relates to the field of computer software, and discloses a focus element navigation method in a human-computer interface, which solves the problem of more occupied system resources during navigation by the prior art. The technical scheme has the key point that the method comprises the following steps of: a, establishing a data structure according to coordinates of the positions of elements and height and width data of the elements; b, filling the acquired coordinates and the height and width data of the elements in the data structure, and establishing an element management queueobject; c, when a navigation event comes, determining a set of navigable effective cutting elements, and judging whether the set is empty, if so, executing a step d, otherwise executing a step e; d, using the current focus element as a focus element after the navigation event is triggered, and turning to a step f; e, searching a focus element most close to the current focus element in the navigation direction, using the searched focus element as the focus element after the event is triggered, and turning to a step f; and f, acquiring the focus element after the navigation. The method has the advantages of less occupied system resources and high focus navigation efficiency, and is widely applied to various embedded devices.

Description

technical field [0001] The invention relates to the field of computer software, in particular to a method for navigating focus elements in a man-machine interface. Background technique [0002] Human-computer interaction technology (Human-Computer Interaction Techniques) refers to the technology of realizing the dialogue between human and computer in an effective way through computer input and output devices. It includes that the machine provides a large amount of relevant information and prompts for instructions, etc. through output or display devices, and people input relevant information, prompts, instructions, and answer questions to the machine through input devices. Human-computer interaction technology is one of the important contents in computer user interface design. It is closely related to the subject areas of cognition, ergonomics, psychology and so on.
