摘要

目的降低ALS患者的认知负荷,提出一套适用于ALS患者的眼控交互界面设计原则。方法选用市面上ALS患者使用的眼控交互界面进行实验,实验主要分为自由浏览测试、任务测试、主观评价测试3个阶段。根据实验结果发掘界面存在的问题,并提出相应的设计原则,运用设计原则对原界面进行设计优化,得到优化后的界面。再根据眼动数据（眨眼率、眨眼时间、总注视点数、瞳孔直径、热区图、AOI注视率）、绩效数据（任务完成时间、任务完成率）和主观数据（NASA-TLX量表）,对比分析原界面和优化后界面的认知负荷。结果优化后界面的眼动数据和绩效数据均优于原界面,主观认知负荷也小于原界面。结论提出的ALS患者使用的眼控交互界面设计原则具有一定可行性,主、客观认知负荷综合分析的方法适用于ALS患者的眼控交互界面优化分析。

Abstract

The work aims to reduce cognitive load for ALS patients and propose a set of design principles of eye- controlled interaction interfaces suitable for ALS patients. Initially, experiments were conducted using existing eye-control interaction interfaces available in the market, focusing on three phases: free browsing tests, task tests, and subjective evaluation tests. These experiments identified problems with the current interfaces, leading to the development of corresponding design principles. Then, the design principles were applied to optimize the original interface, and compare the cognitive load of the interface before and after optimization by eye movement data (such as blink rate, blink time, total fixation number, pupil diameter, hot zone map, AOI fixation rate), performance data (task completion time and task completion rate) and subjective cognitive load (NASA-TLX scale). The eye movement data and performance data of the optimized interface were both superior to those of the original interface, and the subjective cognitive load was also less than that of the original interface. The results show that the proposed design principle of eye-controlled interfaces for ALS patients is feasible and the comprehensive analysis method of subjective and objective cognitive load is suitable for the optimization analysis of eye-controlled interfaces in ALS patients.
