This research seeks to analyze if there exists an understanding of structural design principles among untrained humans. Building forms and styles have evolved since the earliest structures. For thousands of years buildings were limited by naturally occurring materials. Designs of those periods reflected the structural principles of those materials. In the last few hundred years technological advances have provided structural methods which radically altered how buildings can be designed. An example is the difference in column spacing between historic and modern buildings, where the former has much tighter spacing due to natural material’s spanning limitations.
To analyze the understanding of untrained humans an eye-tracking study was conducted using A.I.-3M-VAS eye-tracking software. This technology utilizes artificial intelligence to graphically display eye gaze sequences, patterns, and durations of focus. The software reflects the first few seconds of eye-tracking, providing insights into subconscious reactions before a logical response is formed. Images of structural elements were designed digitally to reflect a variety of forms, maintain cohesiveness, and remove visual variables. Each image was individually processed through the software providing isolated results.
The results of the study show consistent patterns of focus on locations of structural significance, such as bearing points, connections, and material loads. The consistency by which these concepts received focus concludes that there is an innate human ability to locate structural methods of building. Of note the structural forms which adhered to the limits of natural materials registered different eye tracking patterns than the modern manipulated material forms. The historic methods displayed even tracking throughout the structure, whereas the modern methods created hot spots at the points of greatest structural significance. The differences further emphasizes that untrained people are not limited to just understanding familiar structural forms. This will allow for further research on the physiological effects between form types.
