养老机构居室色彩与材质要素的视觉舒适度评价

在老龄化背景下,探讨老年人在养老机构居室空间中的视觉需求.从老年人视觉舒适角度出发,首先,通过实地调研并结合正交实验设计获得场景样本,应用虚拟现实技术构建以色彩和材质交互因素为变量的沉浸式虚拟场景;然后,将主观心理实验与客观生理实验相结合,主观心理实验采用层次分析法和语义差异法,客观生理实验测量被试者心电R-R间期和心率指标;最后,运用SPSS软件对实验数据进行差异性分析和协方差分析,综合对比分析主观心理实验数据和客观生理实验数据,提出基于视觉舒适下的养老机构居室空间色彩与材质搭配优选图谱及设计建议.

Study on Visual Comfort of Color and Material Elements in Bedroom of Pension Institution

Under the aging background, the visual demands of the elderly in the bedroom of pension institutions were discussed. From the perspective of visual comfort of the elderly, the scene samples were obtained through field research and orthogonal experimental design, and the immersive virtual scene with interactive factors of color and material as variables was constructed by virtual reality technology. The subjective psychological experiment was combined with the objective physiological experiment. In the subjective psychological experiment, the analytic hierarchy process and the semantic differential were adopted; in the objective physiological experiment, the subjects’ R-R interval and heart rate indicators were measured. Finally, SPSS software was used to analyze the difference and covariance of the experimental data, and the subjective psychological experimental data and objective physiological experimental data were analyzed comprehensively and contrastively, the optimal map and design suggestions are put forward for the color and material collocation of the bedroom of pension institutions based on visual comfort.
