ITap Index Finger Tap Interaction by Gaze and Tabletop Integration

This dataset contains experimental results evaluating ITap, a novel index finger tap interaction technique that integrates gaze-based object selection with tabletop touch gestures. The dataset includes Task Completion Time (TCT), Error Rate, System Usability Scale (SUS) scores, and NASA-TLX workload scores obtained from user studies.<br>1. Task Completion Time (TCT)TCT represents the time taken by participants to complete each interaction task using ITap.The dataset provides TCT values measured across different target distances and interaction scenarios.2. Error RateThe error rate measures the number of incorrect selections or unintended interactions per trial.It helps assess the precision and reliability of the ITap method compared to alternative selection techniques.3. System Usability Scale (SUS) ScoresThe SUS is a widely used usability assessment questionnaire.<br>4. NASA-TLX Workload ScoresNASA-TLX is a subjective workload assessment tool used to measure the cognitive and physical demands of ITap.It includes six subscales: mental demand, physical demand, temporal demand, performance, effort, and frustration.The dataset provides NASA-TLX ratings to evaluate the overall user burden when using ITap.

本数据集收录了针对ITap的评估实验结果，ITap是一种将基于视线的物体选择与桌面触摸手势相融合的新型食指点击交互技术。本数据集包含通过用户研究获取的任务完成时间（Task Completion Time, TCT）、错误率、系统可用性量表（System Usability Scale, SUS）得分以及NASA-TLX工作负荷得分。
1. 任务完成时间（Task Completion Time, TCT）：TCT指代参与者使用ITap完成每一项交互任务所耗费的时长。本数据集提供了在不同目标距离与交互场景下测得的TCT数值。
2. 错误率：错误率用于衡量每次试验中出现的错误选择或非预期交互的次数，可用于评估ITap方法相较于其他可选选择技术的精度与可靠性。
3. 系统可用性量表（System Usability Scale, SUS）得分：SUS是一款被广泛应用的可用性评估问卷。
4. NASA-TLX工作负荷得分：NASA-TLX是一款用于衡量ITap所带来的认知与体力需求的主观工作负荷评估工具，其包含六个子维度：心理需求、体力需求、时间需求、表现水平、努力程度以及挫败感。本数据集提供了NASA-TLX评分，用于评估使用ITap时的整体用户负担。
