Context-based presets for lighting setup by Kyungah and Jeongmin

Kyungah Choi and Jeongmin Lee published an article entitled as, “Context-based presets for lighting setup in residential space” in Applied Ergonomics (Vol52. 222-231). This study identified context-based lighting setup presets for residential space, which can be applied as the basis for designing a user-centered LED illumination control interface. The multilateral relationships between household activities, affects, and lighting setups were explored to derive twenty context-based presets for the residential space, varying diversely in hue.


This study aims to derive context-based lighting setup presets in residential space by exploring the multilateral relationships among household activities, affects, and lighting setups. Three procedures were involved: First, sixty affective words were evaluated through which seven affect factors were extracted to facilitate the evaluation of colored illumination in the subsequent experiment. Second, in the user study, seven affect factors and thirty household activities were used to evaluate 147 lighting setups extracted from combinations of twelve hues, six illuminance levels, and three purity levels. As a result, twenty lighting setup presets were derived that were not only activity-based, but affect-based as well. Lastly, the twenty presets were prototyped as a set of testbed to further explore potentials and limitations. This study demonstrates that intuitive, context-based presets can help users explore the effects of colored illumination in creating a diverse range of user experiences.
