Study on selection of native greening plants based on eye-tracking technology

Abstract

The selection of native greening plants to improve rural greening technology is crucial for enriching methods of building rural plant landscapes. However, there are few studies from the perspective of visual preference using quantitative methods. By using eye-tracking technology, this study studies students in the Central South University of Forestry and Technology and villagers in Changkou Village, Fujian Province, employing pictures of plant organs—leaves, flowers, and fruits—as stimulating materials to analyze five indicators: the total duration of fixations, the number of fixations, average duration of fixations, average pupil size and average amplitude of saccades. A number of findings came from this research First, people visually prefer leaves, followed by flowers and fruits. In terms of species, Photinia × fraseri, Metasequoia glyptostroboides, Photinia serratifolia, Cunninghamia lanceolata and Koelreuteria bipinnata have higher overall preference. Families such as Malvaceae, Fabaceae, Araliaceae, Myricaceae and Cupressaceae have stronger visual attraction than others. Second, there are distinct differences in the preference of shapes and textures of leaves: aciculiform, strip, cordiform, sector and jacket-shape are more attractive; leather-like leaves have a higher visual preference than paper-like leaves; different colors and whether leaves are cracked or not have little effect on leaf observation. Third, the preference for flowers with different inflorescence and colors is significant. Capitulum, cymes and panicles are more attractive; purple is the most preferred color, followed by white, yellow and red. Finally, there are significant differences in preferences for fruit characteristics, with medium-sized fruits and black fruits preferred, while kidney-shaped and spoon-shaped fruits are considered more attractive. Pomes, pods, samaras, and berries have received relatively more attention.

Gender Differences and Optimizing Women’s Experiences: An Exploratory Study of Visual Behavior While Viewing Urban Park Landscapes in Tokyo, Japan

“…Commonly used eye-movement information provided by eye trackers mainly includes fixation, saccade, and follow [26]. In eye-tracking experiments using static images as materials, the eye-movement behaviors involved are predominantly fixation and saccade [33].…”

“…As more than 80% of human sensory input is visual [25], landscape perception and preference are largely dependent on vision [26]. Moreover, providing visual enjoyment is an important function of urban parks.…”

Drought- and Salt-Tolerant Plants of the Mediterranean and Their Diverse Applications: The Case of Crete

“…According to interviews of owners of private green spaces and visitors of public and common use green spaces where this vegetation was established, it was notable that native Mediterranean plants fulfil the aesthetic purpose and can be used in private and public green spaces. The adequate aesthetic value of Mediterranean plants for public and private green spaces has been previously demonstrated in the literature [17,18,190], and can be attributed to their full harmonization with the natural landscape and the capacity to blend in, update and preserve cultural heritage, thus appealing to non-material criteria. For example, trees such as Cercis siliquastrum L., Sambucus nigra L., Styrax officinalis L., and shrubs such as Nerium oleander L., Calicotome villosa (Poir.)…”
