4. 成果介绍
· 该研究针对内置式标签地图的可用性与易用性问题,借助亚马逊劳务众包平台(Amazon Mechanical Turk)开展用户实证研究,利用一系列信息获取任务的反馈情况来评估内置式标签地图的可用性问题,利用用户在使用地图时的信心、易读性和偏好性等来评估内置式标签地图的易用性问题。此外,还对标签方向、制图区域轮廓形状带来的用户反馈差异性进行了统计分析。用户反馈结果显示内置式标签地图在一些快速形成文本内容概况的任务中表现优异,用户使用的信心指数较高,但在搜索特定标签时性能有所下降,同时,其可读性和布局还有待进一步改善。此外,制图区域轮廓形状对内置式标签地图的可用性具有显著性影响,标签方向和制图区域轮廓形状对内置式标签地图的易用性有显著影响,不同性别的用户表现略有不同。该研究有助于进一步改善标签地图的设计效果。
