Analysing and modelling sequences of eye movement behaviour during visual search

视觉搜索过程中的眼动是一种重要的行为，有助于我们识别和检查环境中的不同物体。我们经常从事视觉搜索，这是一项在我们的日常生活和几个关键领域（如机场安全，放射照相和法医搜索）中具有重要意义的任务。拟议的研究项目旨在检查搜索者在视觉搜索过程中的眼球运动序列。一系列问题有待探索，包括搜索者如何计划他们的眼睛从一个位置到另一个位置的运动，在视觉搜索期间，在他们忘记并返回到先前访问的对象之前，搜索者可以在他们的记忆中保存多少对象（即，记忆容量），以及当我们搜索时无法识别对象。这些概念中的许多概念以前只通过查看平均值或总体水平进行了部分检查。然而，相对较少的工作已经进行了检查时，以及为什么某些行为发生在视觉搜索。因此，该项目将关注搜索者计划在当前固定之外的未来固定的程度，以及搜索者记住他们已经搜索过的地方的程度。此外，个体差异，如工作记忆容量可以影响搜索和固定规划的记忆的详细说明将被检查。总的来说，该项目旨在开发一种新的视觉搜索模型，可以解释搜索者在搜索环境中的目标时所做的固定序列。

Eye movement during visual searching is an important behaviour that help us identify and examine different objects within our environment. We engage in visual search regularly and it is a task with great significance both in our day-to-day life and in several critical domains such as airport security, radiographic and forensic searches. The proposed research project is aimed at examining sequences of eye movements that searchers make during visual search. A range of issues are to be explored, including how searchers plan the movements of their eyes from one location to another, how many objects searchers can hold in their memory during visual search before they forget and return to a previously visited object (i.e., memory capacity), and failures to identify objects when we search. Many of these concepts has only been partially examined before by looking at averages, or overall levels. However, relatively little work has been conducted that examined when and why certain behaviours occur during visual search. Therefore, the project will look at both the degree to which searchers plan future fixations beyond the current fixation, as well as the degree to which searchers remember where they have already searched. In addition, a detailed account of how individual differences such as working memory capacity can influence memory in search and fixation planning will be examined. Overall, the project aims to develop a new model of visual search that can explain the sequences of fixations made by searchers when they search for a target in their environment.
