摘要
对多媒体人机交互界面的视觉精度进行评估,能够提高多媒体人机交互界面的用户体验。对人机交互界面视觉精度评估,需要计算结构信息强度,获取评估值,完成人机交互界面视觉精度的评估。传统方法首先检测图像质量,计算精度评分值,但忽略了获取评估值,导致评估效果不理想。提出多媒体人机交互界面视觉精度评估方法,结合Harris特征点检测算法,提取人机界面视觉显著性区域,计算界面子图像平均结构信息能量及结构信息强度,获取评估值。仿真测试结果表明,所提方法大大提高了多媒体人机交互界面的用户体验。
Traditional evaluation method of vision precision of multi - media human - computer interface always ignores acquisition of evaluation value, which leads to unsatisfied estimation effect. In order to solve the problem, a new evaluation method is proposed. Integrated with algorithm of Harris feature point detection, vision salient region of human - computer interface is extracted. Average energy and strength of structural information of interface sub - im- age are calculated. Thus, evaluation value is acquired. Simulation results shows that the proposed method improves user experience of the multimedia human - computer interface by a large margin.
