This thesis project presents a research through design process that has aimed to explore how we can design interactive technologies that can support mindfulness practices in beginners. This has been done by designing a meditative lamp, Lumina, which can be controlled by the user’s neural oscillations. The user interacts with the lamp by changing alpha and beta brain waves levels through meditation. The prototype has been evaluated with four participants and the testing sessions had three stages: a preliminary questionnaire to learn about participants' mindfulness level, interaction with my prototype providing the opportunity to explore mindfulness and electroencephalography (EEG), and a post-interview to reflect on their experience with the prototype. The biggest challenge of this project was to support mindfulness without disrupting the practice. Lumina has been developed through an iterative process, guided by relevant literature and works in the field of meditation, neurology, and calm technology.
