Smooth pursuit is a physiological phenomenon of human eyes, which can be used as eye-control interaction to avoid the "Midas" problem. This article describes smooth properties continuous variable tasks under Euclid's algorithm. Two experiments were conducted investigate effects slider speed, initial position "plus," and value on interactions. The speed are combined in 12 combination forms, positions divided into 7 cases. Then, optimal forms case derived. Experiment 1 four levels up, down,...

Abstract To investigate a suitable design of interactive objects in the fixation‐triggered eye‐control interface, this study conducted two ergonomic experiments based on location an object, area and distance between adjacent objects. Experiment 1 investigated priority distribution different regions recommended values object sizes regions. The results showed that middle‐middle (MM) is optimal area, while middle‐left (ML) middle‐right (MR) upper‐left (UL) are suboptimal areas, remaining...

Multiple-view visualisation leads to additional switching cost on attention management between viewports. In this study, we compare the cueing effect of chromatic and achromatic colours mitigating viewport in multiple-view visualisations through dual-task paradigm. There is a concurrent need for managing within viewports, performing three single-digit mental addition task, which poses challenge capacity-limited working memory (WM). Response time total fixation count support benefit...

Presenting hyperlinks in the form of linear lists is mainstream visualization method semantic information space. Users need to click and jump multiple pages forage perceive relation between connectivity within The jumping process would interfere with learning understanding space, increase cognitive load retrieval degrade user experience. In this paper, an experiment conducted investigate exploratory search behaviors list visualization. We create two tasks, use analysis questionnaire surveys...

The information cluster that supports the final decision in a task is usually presented as series of information. According to serial position effect, result easily affected by presentation order In this study, we seek investigate how mode commodities and informativeness on shopping website will influence online decisions. To end, constructed two experiments via virtual environment. first experiment suggests effect can induce human computer interaction decision-making bias, user results...

Nowadays, people need to process a great deal of complex information, and make more elaborate estimations or decisions. One particular concern when handling information is that the first piece tends bias cognition results in estimation deviation, which referred as anchoring effect. Currently, some researchers on visualization suggest effects can not only be found classical numerical anchors, but form visual anchors. Recent research concerning investigated existence variety forms tasks data...

This paper explores the visual navigation and cognitive effects of color cues on user's decision-making task under multiple coordinated views display. In this paper, concept information scent is proposed to put forward a method for evaluating premise The eye movement index its parameters obtained by tracking technology are quantitatively evaluated analyze explore users in completing different types decision tasks whether there valid or not. It can provide effective theoretical support...

Spatial aggregation and small multiples are two mainstream visualization presentation methods for temporal sequence data. This study compares the effect of spatial aggregated in mental map construction with three task genres: peak value identification (Task 1), variation tracking 2), trend comparison 3). Spatially timestamps get transited through animations. Task completion time favors 1, but animated transition is more favorable 2 3 terms error rate. Subjective rating results aligned...

2.5D graphic or Isometric graphic, as a common expression method, has been fully developed in 2021 and become prevalent UI illustration element. With the rapid development of computer technology, many two-dimensional images are analyzed calculated digitally, integrated data efficiently automatically generated. Aesthetic evaluation starts from subjective perceptual to rational digital calculation. In order better calculate aesthetic combining various researches plane existing index methods,...

Abstract In the present study, we focus on priming effect of colour mitigating attentional reorientation cost, which is led by re-constructing frame reference for attention shift and visual search in sequential presentations temporal data visualization. The study involves two experiments using complementary recordings behavioural performance eye-tracking events. Two aspects primes are highlighted: prime validity perceptual accessibility. A task paradigm integrating feature keeping-track was...

Abstract The paper by Ningyue Peng, Chengqi Xue, Haiyan Wang, Yafeng Niu and Lei Wu, published in Interacting with Computers (August 2021), explores the use of colour to influence behavioural performance using eye-tracking.

View switching, for example different information density, type and magnitude, will cause additional switching cost between scene. In this paper, the user interface of density be used to explore view transition through dual-task paradigm. We use visual-auditory task observe interactive effect two tasks. Subjects need do searching counting in visual scene auditory response meantime. find that 1) (information density) generate from low high by analyzing performance; 2) mutual is obvious when...
