Problems solved by technology

However, the above-mentioned models are all about stationary targets, they cannot analyze the performance of users in the task of moving target selection, and we cannot use them to design moving target selection technology and find a new user performance model for moving target selection. It is of great significance to understand the performance of users in the task of moving object selection and to develop new moving object selection techniques.

Embodiment Construction

[0031] In order to make the above-mentioned features and advantages of the present invention more comprehensible, the following specific embodiments are described in detail in conjunction with the accompanying drawings.

[0032] This embodiment provides a method for selecting a moving target based on user performance model correction, such as figure 1 As shown, the steps are as follows:

[0033] 1) Display the content of the interface, and the optional targets contained in it are represented by a set as T={t 1 ,t 2 ,...,t n};

[0034] 2) Wait for the user's input until a selection point s appears;

[0035] 3) After obtaining the selected landing point s, for the optional target set T, calculate the probability set P={P(t 1 |s),P(t 2 |s),…,P(t n |s)};

[0036] 4) take t * (t * ∈T) such that P(t * |s) is the largest in P, and t * as the final target.

[0037] In step 1), the interface content is the content displayed by the general interactive system, and the presen...

Abstract

The invention provides a moving target selection method and a moving target selection system based on correction of a user presentation model. The method comprises the steps of performing dimension matching on a display interface, wherein an optional target included in the interface is expressed by a target set; acquiring a selection fall point, and calculating a selected probability of each optional target in the target set according to the selection fall point to obtain a probability set; taking the optional target corresponding to a maximum probability in the probability set as a final selected target. According to the moving target selection method and the moving target selection system based on correction of the user presentation model, for a moving target selection task, a target selected fall point distribution model is established, and the moving target selection is further corrected through the model to improve the efficiency of interactive tasks.

Description

technical field [0001] The invention belongs to the field of computer graphic user interfaces, and in particular relates to an auxiliary selection method and system for moving objects in a graphic user interface. Background technique [0002] In recent years, interactive systems with dynamic content such as computer games, traffic control display systems, and video surveillance systems have become more and more ubiquitous, and virtual reality (Virtual Reality, VR) and augmented reality (Augmented Reality, AR) technologies have further enriched these interactive systems. content in a dynamic and rapidly changing interactive scenario. In this kind of user interface with dynamic content, which contains a large number of moving targets, it is common and challenging to select the target on the move. The user needs to plan to press the button to capture the target while continuously tracking the target (Reference: Khalad Hasan, ToviGrossman and Pourang Irani. "Comet and target gh...
