ABSTRACTIn human-computer interactions, higher-level visuospatial function is likely needed to effectively use the interface. The aim of this study is to clarify whether individuals with visuospatial defects can use electronic devices effectively. We quantitatively and qualitatively analyzed the ability of seven individuals with Bálint syndrome and seven individuals with left-unilateral spatial neglect (USN) to input a digit sequence into a flat touch interface. Control groups consisted of seven individuals with memory deficits and 11 healthy individuals. Participants with Bálint syndrome took longer and had more hesitations than the USN group and the two control groups to input numerical sequences (Steel-Dwass test, p < .01). In addition, participants with Bálint syndrome had a high percentage of hesitations for exploration of the button array on the interface relative to USN and the memory deficit group (Fisher's exact test, p < .05). Regarding neuropsychological data, participants with Bálint syndrome had a lower score for visuospatial working memory than participants with USN and the memory deficits control group (Steel-Dwass test, p < .01). The results shed some light on the relation between visuospatial working memory deficits and the spatial perception of interface layouts and spatial control during electronic device operation.

视觉空间工作记忆障碍个体对电子设备的数字输入操作

摘要在人机交互中,可能需要更高级别的视觉空间功能才能有效地使用界面。本研究的目的是阐明视觉空间缺陷的个体是否可以有效地使用电子设备。我们定量和定性地分析了 7 名 Bálint 综合征患者和 7 名左单侧空间忽视 (USN) 患者将数字序列输入平面触摸界面的能力。对照组由 7 名有记忆缺陷的人和 11 名健康人组成。与 USN 组和两个对照组相比,Bálint 综合征参与者输入数字序列的时间更长,犹豫更多(Steel-Dwass 检验,p < .01)。此外,与 USN 和记忆缺陷组相比,Bálint 综合征参与者在探索界面上的按钮阵列时有很大的犹豫(Fisher 精确检验,p < .05)。关于神经心理学数据,Bálint 综合征参与者的视觉空间工作记忆得分低于 USN 参与者和记忆缺陷对照组(Steel-Dwass 测试,p < .01)。结果揭示了视觉空间工作记忆缺陷与电子设备操作过程中界面布局和空间控制的空间感知之间的关系。Bálint 综合征参与者的视觉空间工作记忆得分低于 USN 参与者和记忆缺陷对照组(Steel-Dwass 测试,p < .01)。结果揭示了视觉空间工作记忆缺陷与电子设备操作过程中界面布局和空间控制的空间感知之间的关系。Bálint 综合征参与者的视觉空间工作记忆得分低于 USN 参与者和记忆缺陷对照组(Steel-Dwass 测试,p < .01)。结果揭示了视觉空间工作记忆缺陷与电子设备操作过程中界面布局和空间控制的空间感知之间的关系。
