Research on Optimization Design of Corridor Entry Space of Elderly Facilities Based on Visual–Perceptual and Electroencephalogram Feedback Mechanisms

This study conducted research and discussion on the irrational layout of the corridor entry front room space in Chinese elderly facilities and proposed a design strategy for this spatial area. Based on a survey of elderly facilities and the general needs of the elderly, three design elements were added to the corridor front room space: windows, furnishings, and vertical greening. A model was built and eight different sets of pictures were generated; 28 subjects viewed the pictures according to their personal preferences while EEG data and subjective questionnaires were collected and analyzed. The results indicated that [Scene WF] was more popular among the elderly and that the demand for furnishings was higher among the elderly. The EEG results also showed that the energy in the frontal region of [Scene WF] was significantly higher than the other scenes. Significance was found between the AF3 and AF4 electrodes in the frontal region and the time and number of viewings (p < 0.01), as well as with subjective satisfaction (p < 0.01). These findings demonstrate that adding these three design elements to this space helped the elderly to have a more enjoyable experience, created a more pleasant and comfortable environment for the elderly, and improved the overall efficiency of the interior space. Additionally, the study provides valuable information for the design of future elderly facilities.
