摘要
目的通过对跑步机人机界面的可用性评估,提出再设计解决方案,进一步提升产品用户体验。方法首先,采用主客观多维可用性评估方法,对用户与跑步机之间的人机界面进行测量。其中,客观可用性评估采用基于眼动跟踪技术测量的眼动指标(注视点、平均注视时间)以及行为指标(任务完成时间、任务成功率)进行分析;主观可用性评估采用基于用户主观评价的问卷调查方法。其次,结合主客观评价实验结果,提出跑步机人机界面改进建议,并对其进行再设计。结果通过实验结果分析及相应改进建议,设计获得更优的跑步机人机界面。结论构建的主客观多维可用性评估方法适用于跑步机人机界面的评价与改进,并为人机界面设计的测量体系提供理论基础与实践方法。
According to the usability evaluation of treadmill human-machine interface, we propose a redesign solution for improving user experience further. Firstly, we apply subjective and objective multidimensional usability evaluation method to test human-machine interface between user and treadmill. The eye movement index like fixation point and av- eraged fixation time based on eye tracking technique and behavior index like task finish time and task success rate are used for objective usability evaluation. Questionnaire survey based on user is used for subjective usability evaluation. Then, combined with the subjective and objective evaluation results, we make suggestions for improving the treadmill human-machine interface, and redesign it. Based on the result analysis and improvement suggestions, the better treadmill human-machine interface is designed. The proposed subjective and objective multidimensional usability evaluation method can be used for evaluation and improvement of treadmill human-machine interface, and can provide theoretical basis and practical method for testing system of human-machine interface design.
