针对视线交互技术中的点击定位问题,本研究在视线辅助点击技术的基础上引入气泡光标技术,提出了视线辅助气泡光标技术,并考察了该技术在精确定位方面的作用。结果显示:(1)视线辅助气泡光标的点击操作绩效显著优于手控尖点光标,并且时间知觉更低;(2)视线辅助气泡光标的点击操作时间显著慢于手控气泡光标,并且主观努力程度更高;3)目标位置对三种光标类型的操作绩效均有显著影响,且对视线辅助气泡光标的影响作用最大。本研究的结果为视线辅助点击技术的优化提供了新思路。 相似文献

眼动交互中边框和视标对作业绩效的影响研究 总被引:1,自引:0,他引:1
研究人计算机界面设计中的眼动交互反馈方式,为优化基于视线追踪技术的人计算机界面设计提供工效学依据。12名被试在交互对象有无边框提示和当前注视位置有无视标反馈的四种组合条件下,通过眼动交互完成目标选择任务,由计算机自动记录作业时间、选择错误和超时数目。结果发现,有无当前注视位置的视标反馈对作业时间有显著影响,有视标反馈可加速目标字母的搜索与定位过程和目标激活过程,由视标反馈所产生的作业时间下降,主要由目标定位时间的缩短所致;边框提示对用户的作业绩效无显著影响。根据上述结果可得以下结论:对当前注视位置提供视标反馈是一种有效的反馈方式,基于视线追踪的人机交互系统应为用户提供这种反馈信息。 相似文献

由于人眼注视的方位能够表达用户的兴趣中心等信息,使得基于眼动的用户界面备受关注,同时眼动也成为攫取当前认知加工过程的一个窗口。本研究采用2排列方式×6目标项位置的被试内设计,主要考察了眼动人机界面中交互对象的不同空间排列方式及目标项位置对选择工效的影响,以期为设计和优化基于视线追踪的人机交互界面的布局提供心理学依据。所获得的主要结论如下:(1)在基于视线追踪的人机交互中,对象水平排列方式优于垂直排列方式;(2)不同对象排列方式影响目标项位置对作业时间的效应模式,对象水平排列时,作业时间随着目标位置右移而线性递增;垂直排列时,作业时间随目标位置下移以非线性方式递增;(3)目标项位置仅影响目标定位时间,目标激活时间不受对象空间排列方式和目标项位置的影响;(4)基于视线追踪的人机交互系统其对象排列方式以水平方式为宜 相似文献

采用线段平分任务,以无文字线索作为基线条件,考察文字线索的浏览方向、空间位置和移动光标对具有两种不同方向阅读经验的熟练双语者伪忽视的影响。结果发现,无文字线索条件下,光标从左往右方向移动时被试的判断偏向于线段中点的右侧,而从右往左移动时,偏向于线段中点的左侧。在有文字线索条件下发现,文字线索的浏览方向和空间位置的交互作用显著,简单效应检验显示文字线索的浏览方向和空间位置一致时伪忽视明显,不一致时伪忽视消失。结果表明,文字线索浏览方向、空间位置与移动光标能够影响伪忽视。伪忽视的存在和消失,不仅与眼球运动有关,还有与大脑两半球的激活水平有关。研究结果支持了视觉扫描假设和激活朝向假设。 相似文献

摘 要 采用E-prime编排认知实验研究照明环境与TFT-LCD视觉显示终端界面背景饱和度的交互效应对视觉绩效的影响。依据字母视力表设计原理制作认知材料,以认知速度与准确率为视觉绩效评价指标。结果发现,照度与饱和度的交互效应对视觉绩效存在显著影响,色温与饱和度的交互效应仅对准确率存在显著影响,三因素交互作用对准确率存在显著影响。结果表明,不同照度、色温下,通过调节显示终端界面背景饱和度可改善视觉绩效。 相似文献

体感交互是新兴的人机交互方式;当前,相关的人因学研究相对缺乏。本研究采用典型任务结合主观评价法,首次探索了用户运动信息反馈形式对体感交互用户体验的影响。笔者从易学性、控制性、情感与心理负荷四个方面,比较了有、无人形反馈形式对游戏体感菜单操作可用性的影响。结果发现,二者在心理负荷上无差异,无人形反馈在易学性上优于有人形,但有人形反馈在控制感上优于无人形,且更受用户喜爱。基于该结果,笔者建议在体感操作界面上使用有人形反馈。 相似文献

Eye movements reveal what is at the center of people's attention, which is assumed to coincide with what they are thinking about. Eye-movement displays (visualizations of a person's fixations superimposed onto the stimulus, for example, as dots or circles) might provide useful information for diagnosing that person's performance. However, making inferences about a person's task performance based on eye-movement displays requires substantial interpretation. Using graph-comprehension tasks, we investigated to what extent observers (N = 46) could make accurate inferences about a performer's multiple-choice task performance (i.e., chosen answer), confidence, and competence from displays of that person's eye movements. Observers' accuracy when judging which answer the performer chose was above chance level and was higher for displays reflecting confident performance. Observers were also able to infer performers' confidence from the eye-movement displays; moreover, their own task performance and perceived similarity with the performer affected their judgments of the other's competence. 相似文献

Recent studies on gaze behaviours in individuals with autism spectrum disorder (ASD) have utilised “live eye tracking.” Such research has focused on generating quantitative eye tracking measurements, which provide limited (if any) qualitative contextual details of the actual interactions in which gaze occurs. This article presents a novel methodological approach that combines live eye tracking with qualitative interaction analysis, multimodally informed conversation analysis. Drawing on eye tracking and wide-angle video recordings, this combination renders visible some of the functions, or what gaze “does,” in interactional situations. The participants include three children with ASD and their adult co-participants during body-movement gaming sessions. The article demonstrates how quantitative eye tracking research can be extended qualitatively using a microanalytic interaction analysis to recontextualise the gaze shifts identified. The findings in this article show that the co-participants treat a child’s gaze shifts differently depending on when these occur in a stream of other action. The study suggests that introducing this qualitative dimension to eye tracking research could increase its ecological validity and offer new insight into gaze behaviours in ASD. 相似文献

In clinical reports, individuals high on social anxiety are often described to avoid gaze at other people, whereas several experimental studies employing images of persons yielded conflicting results. Here, we show that gaze avoidance crucially depends on the possibility of social interactions. We examined gaze behaviour in individuals with varying degrees of social anxiety in real-life and in a second group of participants using a closely matched laboratory condition. In the real-life situation, individuals with a higher degree of social anxiety had a reduced bias to look at near persons compared to individuals with a lower degree of social anxiety, while gaze behaviour in the laboratory group was not modulated by social anxiety. This effect was specific to social attention since there was no corresponding effect regarding fixations on objects. The presence of anxiety effects in real-life but not in the laboratory condition, where participants do not expect to be evaluated by gazed-at conspecifics, points to critical deficits of current laboratory research paradigms in eliciting authentic social attentional mechanisms, possibly leading to spurious results. 相似文献

Gunby, Rapp, Bottoni, Marchese and Wu (2017) taught three children with autism spectrum disorder to follow an instructor's gaze shift to select a specific item; however, Gunby et al. used different types of prompts with each participant. To address this limitation, we used a progressive training model for increasing gaze shift for three children with autism spectrum disorder. Results show that each participant learned to follow an adult's shift in gaze to make a correct selection. In addition, two participants displayed the skill in response to a parent's gaze shift and with only social consequences; however, the third participant required verbal instruction and tangible reinforcement to demonstrate the skill outside of training sessions. 相似文献

We demonstrate that a person's eye gaze and his/her competitiveness are closely intertwined in social decision making. In an exploratory examination of this relationship, Study 1 uses field data from a high‐stakes TV game show to demonstrate that the frequency by which contestants gaze at their opponent's eyes predicts their defection in a variant on the prisoner's dilemma. Studies 2 and 3 use experiments to examine the underlying causality and demonstrate that the relationship between gazing and competitive behavior is bi‐directional. In Study 2, fixation on the eyes, compared to the face, increases competitive behavior toward the target in an ultimatum game. In Study 3, we manipulate the framing of a negotiation (cooperative vs. competitive) and use an eye tracker to measure fixation number and time spent fixating on the counterpart's eyes. We find that a competitive negotiation elicits more gazing, which in turn leads to more competitive behavior. 相似文献

The current study explores the influence of familiarity on explicit eye gaze judgement in preschoolers. We introduce reaction times for touches as a new measure for children studies. Children aged four–six years saw either their caregiver's face or a stranger's face looking at an object or away from it. Children were asked to touch the face that was looking at the object and reaction times to correct touches were measured. Children reacted faster to strangers' faces than to their caregivers' faces. This may indicate that preschoolers used the face of a stranger more effectively as a source of information about the environment and for this reason detected the eye gaze-object relationship faster. In addition, children's reactions were faster in a nonsocial shape-matching task than in the social eye gaze-judgement task. The applied paradigm is appropriate to further investigate the development and influencing factors of explicit eye gaze judgements in preschoolers. 相似文献
