NEM:基于真实感框架的自然用户界面评估方法

NEM: a Natural User Interface Evaluation Method Based on Reality Framework

针对当前自然用户界面缺乏普适性评估方法的问题,基于真实感框架提出一种自然用户界面评估方法——NEM.该方法以真实感框架为基础定义评估指标,对多源数据进行采集及特征提取;并通过层次分析法(AHP)构建指标权重模型,最终给出评估建议;最后以自然用户界面中具有代表性的笔式用户界面为实例,基于NEM方法对Tilt交互任务进行评估,得到了多维度融合的评估结果,并为Tilt交互提供设计建议.实例结果表明,文中方法能够有效地体现自然用户界面的特点,拓宽评估带宽,从而指导自然用户界面的设计和评估.

In this paper,we propose a natural user interface evaluation method(NEM)based on reality framework.This method defines evaluation criteria based on reality framework,extracts features from multi-source data,utilizes AHP method to construct a weight model,and finally provides integrated evaluation result.This paper takes pen-based user interface,one of the most representative NUIs,as an example.We evaluate Tilt interaction tasks based on NEM and get the multi-dimensional integrated evaluation results,which provide design guidelines for Tilt Interaction.It demonstrates that NEM can effectively embody the features of NUI and broaden evaluation bandwidth,and can be used to guide the design and evaluation for NUI as well.
