PCI (Prayer–Computer Interaction)

PCI (Prayer–Computer Interaction) is an artwork series that explores how contemporary humans form spiritual, emotional, and ethical relationships with machines—not as tools, but as silent counterparts in moments of vulnerability, hope, and reflection. Rather than framing technology as an instrument of efficiency or control, PCI places computation within the intimate space of prayer, where interaction is guided by presence rather than output. Prayer is understood not as a belief-bound religious act, but as a universal human gesture—an embodied way of facing uncertainty, seeking healing, and reflecting on one’s place in the world.

Using audio sensing and motion-capture systems, primarily through TouchDesigner and depth-based devices such as Kinect, PCI translates participants’ voices, posture, and movements into evolving visual environments. Any form of prayer or contemplative expression, regardless of religious or cultural background, can become input. By responding to rhythm, stillness, and flow rather than language or belief, PCI creates an interfaith, non-verbal space for self-reflection, personal healing, and exploration of life’s meaning—where technology acts as a quiet medium rather than an authority.

On top of these works, I plan to explore different sensor technologies, such as brainwave, heart rate, and facial tracking for a wider variety of techno-theological expression.
