EXPANSIVE LIGHTING

Abstract:

The composition of visual landscapes significantly impacts the utilization of eye features, consequently reflected in perception. As an outstanding species, human perception holds profound planetary consequences, directly influencing experience and behavior. This paper investigated why humans have become specialized in the certain type of visual attention, referred to as fovea vision. Furthermore, it explores peripheral vision and how these two modes are stimulated by lighting. It is commonly known that we receive and process visual information very differently in fovea and peripheral vision, which suggests a difference in time perception. To quantify the seemingly unquantifiable, the sense of chronological time was used to investigate the experiential variances resulting from fovea and peripheral light stimuli. There was conducted an experiment, designed based on research, where the participants were asked about sense of time, after fovea and peripheral stimuli. Despite time and resource limitations, there was found that sense of time increases with peripheral stimuli. Additionally, that peripheral-time is influenced by what came before, while fovea-time remains consistent. This paper highlights the importance of considering the outer limits beyond the fovea, and suggests that doing so, can bring us closer to our surroundings through embodiment and spatial engagement.

Abstract:

With the intensification of contemporary urbanization, an increasing number of people are living and working in high-density urban environments. The importance of a good indoor environment for human psychology and health is increasingly evident, so researchers are paying more attention to the impact of indoor environments on human health and well-being. This article first extensively searches and organizes theories related to lighting, natural sounds, and indoor environments. Based on this, a mixed method combining qualitative and quantitative research is used to investigate the effects of combining lighting and natural sounds on emotions and productivity. This study intends to provide a scientific basis for the future design of more restorative indoor environments. Finally, the data analysis of the experimental results shows that the environment combined with cool light and natural sound is more helpful in improving people’s well-being, restoring people’s emotions, and improving people’s attention and work efficiency.

Visual Rhythm in light design. How light patterns create atmosphere in a museum

Abstract:

Studies indicate that incorporating light rhythms have the potential to generate an atmosphere of curiosity to further explore a space. In lighting design, we can describe rhythm as the ‘flow of light’ as the repetition of shadow, shading and highlight patterns of an illuminated three-dimensional surface that we experience in space when we walk through it. To further investigate this topic, a survey was conducted in a computer-generated museum setting to examine how rhythmical light scenarios of both artificial and natural light can create dynamic atmospheres so that they influence the spatial exploration. For this purpose, scenarios of two categories were made by relative darkness in order to create “mystery” and brightness for ‘focal glow’. Each scenario included the incorporation of daylight conditions, encompassing both morning and evening settings. The experiment revealed a preference for the “mystery” scenarios and the evening conditions of both “mystery” and the “focal glow” scenarios. Nonetheless, it is advisable to conduct similar experiments in real-life settings to attain more substantial results and minimize potential survey bias.

Keywords: light rhythm, atmosphere, spatial exploration, museum setting, daylight.
